Bio-based is booming. Increasingly more businesses see a healthy business case in products that are not made with fossil raw materials, but with biomass. But where are the opportunities for the Netherlands? And which roles can the government, trade and industry and science play? This PM special contains interviews with and experiences of pioneering entrepreneurs and agricultural attaches in the Netherlands and abroad [Dutch] Biobased is booming. Steeds meer bedrijven zien een gezonde businesscase in producten die niet gemaakt zijn met fossiele grondstoffen maar met biomassa. Waar liggen de kansen voor Nederland? En welke rol is daarbij weggelegd voor de overheid, het bedrijfsleven en de wetenschap? In deze PM-special onder meer interviews met en ervaringen van pionerende entrepreneurs en landbouwattaches in binnen- en buitenland.

The study shows it is possible for the Dutch industry to expand its strong knowledge position to a forceful international competitive position by aiming innovations towards the realization of a biobased economy. The main conclusions of this report are that the biobased economy offers big opportunities for sustainable economic development in the Netherlands and in Europe, but there is no guarantee of success. At a European level a stable and inviting investment climate necessary for biobased economic activity is lacking. In the Netherlands there is a need for a proactive innovation policy to substantially accelerate the development of promising business cases [Dutch] Deze verkenning vertrekt vanuit trends en ontwikkelingen in de wereld en kijkt vervolgens naar de consequenties voor Europa en Nederland. Dit 'van buiten naar binnen' perspectief contrasteert met veel andere analyses die doorgaans vertrekken vanuit de kansen voor bio-based processen en producten en vooral ingaan op de 'gewenste' maatschappelijke context. Gekeken is enerzijds naar globale maatschappelijke trends en anderzijds naar specifieke sleutelactiviteiten binnen het Nederlandse innovatiesysteem. De verkenning gaat met deze benadering niet alleen in op de mondiale en Europese context, maar analyseert ook op systematische wijze de sterkten en zwakten binnen het Nederlandse innovatiesysteem.

The Dutch Agricultural Covenant included a target for sustainable energy of 200 PJ. The agricultural industry is expected to contribute 75 to 125 PJ (bio-energy). The sector is wondering whether this target is realistic. The aim of this project was to map the quality and quantity of residual flows in the agricultural industry that exist and are available or are already deployed for bio-energy (in the Netherlands), both today and in 2020. [Dutch] In het Agroconvenant is een doelstelling opgenomen voor duurzame energie van 200 PJ. Van de agro-industrie wordt een bijdrage van 75 tot 125 PJ (bio-energie) verwacht. De sector vraagt zich af of deze doelstelling wel realistisch is. Het doel van dit project was het in kaart brengen van de kwaliteit en kwantiteit van reststromen uit de agro-industrie die aanwezig of beschikbaar zijn of reeds (in Nederland) ingezet worden voor bio-energie nu en in 2020.

Bles, M.; Schepers, B.; Van Grinsven, A.; Bergsma, G.

2011-03-15

The Dutch status document on bio-energy has been updated with data for the year 2011. This document provides an overview of the amount of energy derived from biomass, a description of the current bio-energy policy framework and a discussion of the extent to which the Netherlands is on track for securing European renewable energy targets. The status document shows there has been a slight increase in the share of bio-energy in overall energy consumption as well as in the total amount of renewable energy generated (which now stands at a little over 4% of gross final consumption). The question, however, is whether this growth is sufficient to meet the European target of 14% renewables in 2020. The limited growth is due partly to the decrease in the amount of energy generated in the category 'other incineration'. In addition, there was a decline in the physical delivery of transport biofuels because certain types of fuel can be 'double-counted' in the records, although they do not contribute to the 14% target. This document provides an overview of the amount of energy derived from biomass, a description of the current bio-energy policy framework and a discussion of the extent to which the Netherlands is on track for securing European renewable energy targets [Dutch] Het statusdocument bio-energie 2011 geeft de huidige status weer van bioenergie in Nederland, inclusief trends en verwachtingen voor de toekomst. Het doel van dit document is inzicht verstrekken aan overheden en marktpartijen in de ontwikkelingen van bio-energie. De kabinetsdoelstellingen voor hernieuwbare energie zijn conform de doelstellingen uit de richtlijn voor hernieuwbare energie (2009/28/EG), die is vastgesteld door de EC. In 2020 moet 14% van het nationale bruto finaal eindgebruik afkomstig zijn van hernieuwbare bronnen, de Nederlandse overheid schat dat dat overeenkomt met 300 PJ. Naar schatting is in 2011 ongeveer 88 PJ aan hernieuwbare energie geproduceerd, ongeveer evenveel

Full Text Available Several disciplines form alliances in primary schools and secondary schools to guide pupils with complex and multifaceted learning and behavioural problems. The functioning of these alliances is discussed in this article. The author presents the results of a qualitative study into the organisation of the alliances at three schools. Based on literature study, interviews, observations and document analyses, the author describes how professionals try to agree during consultation and how they learn from each other. She concludes with recommendations for effective co-operation when pupils need care. These recommendations refer to a clear structure of the alliance, attention for informal processes and professionals who account for their actions by expressing their knowing-in-practice. In basis- en voortgezet onderwijs werken verschillende disciplines samen in de zorg aan leerlingen met complexe gedragsproblemen. In dit artikel wordt verslag gedaan van een kwalitatief onderzoek naar deze samenwerkingsverbanden. In het onderzoek, dat plaatsvond op drie scholen, is gebruik gemaakt van literatuurstudie, interviews, observaties en documentanalyse. De resultaten worden in dit artikel besproken en hebben betrekking op de organisatie van het samenwerkingsverband, op de inhoudelijke afstemming tussen professionals tijdens overlegsituaties en op het leren van elkaar. De auteur sluit af met een aantal aanbevelingen voor effectieve samenwerking rondom zorgleerlingen. Deze aanbevelingen gaan over een heldere structuur van het samenwerkingsverband, aandacht voor informele processen en professionals die hun handelen verantwoorden door hun ervaringskennis expliciet te maken.

The working group on Economic Instruments of the Biodiversity and Natural Resources Task Force addressed the question how the recommendations of the report of the United Nations 'The Economics of Ecosystems and Biodiversity' (TEEB) can be realized in the Netherlands. A selection of topics has been made for which policy proposals are developed which might be promising and can lead to a better protection of the biodiversity. The following proposals were investigated and/or elaborated: decrease of the social discount rate; further greening of the tax system; import levy on bulk commodities; taxes on non-sustainable wood; levy on the use of open space; differential tax on animal proteins; and a revision of biomass incentives. [Dutch] In de Taskforce Biodiversiteit en Natuurlijke Hulpbronnen (TF) heeft een werkgroep Economische Instrumenten zich gebogen over de vraag hoe de aanbevelingen van het rapport van de Verenigde Naties 'The Economics of Ecosystems and Biodiversity' (TEEB) concreet kunnen worden ingevuld in het Nederlandse beleid. Er is een selectie van onderwerpen gemaakt waarvoor beleidsvoorstellen zijn uitgewerkt die kansrijk zijn en leiden tot een betere bescherming van biodiversiteit. De volgende voorstellen zijn nader onderzocht en/of uitgewerkt: verlaging van de maatschappelijke discontovoet; verdere vergroening van het belastingstelsel; importheffing op bulkgoederen; belasting op niet-duurzaam hout; heffing op onttrekking van open ruimte; gedifferentieerde belasting op dierlijke eiwitten; en herijking van stimuleringsbeleid biomassa.

The introduction of Market Based Measures (MBMs) to reduce the CO2 emissions of international sea shipping will have relatively limited economic effects for the Netherlands. Moreover, these effects are largely in line with those in other countries. For the Netherlands, however, the manner in which MBMS are organised and enforced is likely to be particularly important, given the importance of ports to the Dutch economy, the country's relatively large bunker sector, and the fact that Dutch shipowners operate relatively small vessels and on a relatively small scale. MBMs include pricing measures in the form of tax or trade systems, as well as other market-related proposals. In this research study, the consequences are analysed of four international MBM proposals for the Netherlands [Dutch] Om de CO2-uitstoot van de internationale zeevaartsector terug te dringen worden momenteel zogeheten Market Based Measures (MBMs), zoals bijvoorbeeld het veilen van emissierechten of het invoeren van een heffing, overwogen. De invoering van de MBMs zal voor Nederland relatief beperkte economische effecten hebben. Deze effecten wijken bovendien niet bijzonder af van die voor andere landen. De wijze waarop de MBMs worden georganiseerd en gehandhaafd, is voor Nederland mogelijk wel van onderscheidend belang. Dit gezien het belang van de havens voor de Nederlandse economie, de relatief grote bunkersector, en de relatief kleine schepen en kleinschaligheid van de Nederlandse reders.

Moving towards a bio-based and circular economy implies a major focus on the responsible and sustainable utilization of bio-resources. The emergence of nanotechnology has opened multiple possibilities, not only in the existing industrial sectors, but also for completely novel applications of nanoscale bio-materials, the commercial exploitation of which has only begun during the last few years. Bio-based materials are often assumed not to be toxic. However, this pre-assumption is not necessarily true. Here, we provide a short overview on health and environmental aspects associated with bio-based nanomaterials, and on the relevant regulatory requirements. We also discuss testing strategies that may be used for screening purposes at pre-commercial stages. Although the tests presently used to reveal hazards are still evolving, regarding modifi-cations required for nanomaterials, their application is needed before the upscaling or commercialization of bio-based nanomaterials, to ensure the market potential of the nanomaterials is not delayed by uncertainties about safety issues.

Bio-based materials are new materials or chemicals with renewable biomass as raw materials such as grain, legume, straw, bamboo and wood powder. This class of materials includes bio-based polymer, biobased fiber, glycotechnology products, biobased rubber and plastics produced by biomass thermoplastic processing and basic biobased chemicals, for instance, bio-alcohols, organic acids, alkanes, and alkenes, obtained by bio-synthesis, bio-processing and bio-refinery. Owing to its environmental friendly and resource conservation, bio-based materials are becoming a new dominant industry taking the lead in the world scientific and technological innovation and economic development. An overview of bio-based materials development is reported in this special issue, and the industrial status and research progress of the following aspects, including biobased fiber, polyhydroxyalkanoates, biodegradable mulching film, bio-based polyamide, protein based biomedical materials, bio-based polyurethane, and modification and processing of poly(lactic acid), are introduced.

Bio-Based Polymers with Potential for Biodegradability

Directory of Open Access Journals (Sweden)

Thomas F. Garrison

2016-07-01

Full Text Available A variety of renewable starting materials, such as sugars and polysaccharides, vegetable oils, lignin, pine resin derivatives, and proteins, have so far been investigated for the preparation of bio-based polymers. Among the various sources of bio-based feedstock, vegetable oils are one of the most widely used starting materials in the polymer industry due to their easy availability, low toxicity, and relative low cost. Another bio-based plastic of great interest is poly(lactic acid (PLA, widely used in multiple commercial applications nowadays. There is an intrinsic expectation that bio-based polymers are also biodegradable, but in reality there is no guarantee that polymers prepared from biorenewable feedstock exhibit significant or relevant biodegradability. Biodegradability studies are therefore crucial in order to assess the long-term environmental impact of such materials. This review presents a brief overview of the different classes of bio-based polymers, with a strong focus on vegetable oil-derived resins and PLA. An entire section is dedicated to a discussion of the literature addressing the biodegradability of bio-based polymers.

The reported thin-film polymerization has been used as a screening method in order to find bio-based liquid crystalline polyesters with convenient melting temperatures for melt-processing purposes. An in depth study of the structural, morphological and chemical changes occurring during the ongoing polycondensation reactions of these polymers have been performed. Structural and conformational changes during polymerization for different compositions have been followed by time resolved X-ray and Infrared spectroscopy. In this study, bio-based monomers such as vanillic acid and 2,5-furandicarboxylic acid are successfully incorporated in liquid crystalline polyesters and it is shown that bio-based liquid crystalline polymers with high aromatic content and convenient processing temperatures can be synthesized.

Prospects for a bio-based succinate industry.

Science.gov (United States)

McKinlay, James B; Vieille, C; Zeikus, J Gregory

2007-09-01

Bio-based succinate is receiving increasing attention as a potential intermediary feedstock for replacing a large petrochemical-based bulk chemical market. The prospective economical and environmental benefits of a bio-based succinate industry have motivated research and development of succinate-producing organisms. Bio-based succinate is still faced with the challenge of becoming cost competitive against petrochemical-based alternatives. High succinate concentrations must be produced at high rates, with little or no by-products to most efficiently use substrates and to simplify purification procedures. Herein are described the current prospects for a bio-based succinate industry, with emphasis on specific bacteria that show the greatest promise for industrial succinate production. The succinate-producing characteristics and the metabolic pathway used by each bacterial species are described, and the advantages and disadvantages of each bacterial system are discussed.

For almost two decades, the chemical industry has put great effort into developing bio-chemicals,among others to fight global warming caused by greenhouse gas emissions, one of the biggest threats that are faced by our society today. To facilitate a growing and versatile bio-based chemical...... production, the US Department of Energy proposed in 2004 a list of 12 building block chemicals which can either be converged through biological or chemical conversions. Moving toward more bio-based chemicals, the chemical industry does not only claim to reduce climate change impacts, but also...... that they are increasing overall sustainability in chemical production. Whether such claims are justifiable is unclear. When sustainability of bio-based polymer production is assessed, various environmental trade-offs occur that need to be considered. It is not enough to claim that a bio-chemical is sustainable...

Draft of the EU regulation for the infrastructure for alternate fuels. Impact assessment for the Netherlands; Concept EU Richtlijn Uitrol Infrastructuur voor Alternatieve Brandstoffen. Impact Assessment voor NL

2013-08-15

On 24 January 2013, the European Commission approved a proposal for a directive on the rollout of infrastructure for alternative fuels for transport. The directive mostly covers the charging infrastructure for electric vehicles; CNG, LNG and hydrogen refuelling stations for road traffic, and LNG bunker facilities for shipping. On assignment of the Dutch Ministry of Infrastructure and the Environment, ECN conducted an impact assessment of the proposal for the directive for the Dutch situation. The overall conclusion is that the estimates for the Netherlands in the framework of the directive with regard to the required infrastructure for alternative fuels and the investment amount reasonably concur with the government's objectives and the expectations of market parties. Given all uncertainties about numbers and exact costs, the conclusion is drawn that, until the end of 2020, an amount of about Meuro 400 will be needed for investments in the infrastructure for alternative fuels. However, this covers only a part of the investments related to the directive. To realise the objectives, applications for alternative fuels will need to be stimulated and the financial gap in exploiting infrastructures also needs to be financed. As it is difficult to determine beforehand which costs are involved, it is important to maintain flexibility in objectives for volume and realisation pace of the infrastructure for alternative fuels. In this respect, a result obligation to realise a certain volume of infrastructure before a set date, as envisaged by the directive, is not beneficial [Dutch] Op 24 januari 2013 heeft de Europese Commissie een voorstel voor een richtlijn goedgekeurd betreffende de uitrol van infrastructuur voor alternatieve brandstoffen voor transport. De richtlijn heeft vooral betrekking op oplaadinfrastructuur voor elektrische auto's; CNG, LNG en waterstoftankstations voor wegverkeer, en LNG bunkerfaciliteiten voor de scheepvaart.

A method was formulated to map the Flemish sector contributions and foreign contributions to PM10, PM2.5 and ozone concentrations in Flanders. Flemish emissions scenarios from MIRA and the corresponding European emissions scenarios from IIASA were used for this. The content and production of these emissions scenarios were described in the Environment Outlook 2030 Flanders (REF and EUR scenarios) and in the MIRA study 'Particulate matter and photochemical air pollution. Visionary Scenario of the Environment outlook 2030 Flanders. In the context of this study, which emissions and atmospheric chemical processes play an important role in explaining the particulate matter and ozone concentrations in Flanders for the current situation (base year 2007) and for the three emissions prognoses for 2020 were analysed: (1) for an emissions scenario according to current European legislation; (2) for an emissions scenario with a number of additional European emissions reduction measures; (3) for an emissions scenario with further reaching emissions reductions. In general the emissions and the concentrations decrease in the three scenarios for 2020. The changes to emissions are related to sector and place, which has an impact on the relative sector contributions for Flanders.

A brief review of extrusion-based tissue scaffold bio-printing.

Science.gov (United States)

Ning, Liqun; Chen, Xiongbiao

2017-08-01

Extrusion-based bio-printing has great potential as a technique for manipulating biomaterials and living cells to create three-dimensional (3D) scaffolds for damaged tissue repair and function restoration. Over the last two decades, advances in both engineering techniques and life sciences have evolved extrusion-based bio-printing from a simple technique to one able to create diverse tissue scaffolds from a wide range of biomaterials and cell types. However, the complexities associated with synthesis of materials for bio-printing and manipulation of multiple materials and cells in bio-printing pose many challenges for scaffold fabrication. This paper presents an overview of extrusion-based bio-printing for scaffold fabrication, focusing on the prior-printing considerations (such as scaffold design and materials/cell synthesis), working principles, comparison to other techniques, and to-date achievements. This paper also briefly reviews the recent development of strategies with regard to hydrogel synthesis, multi-materials/cells manipulation, and process-induced cell damage in extrusion-based bio-printing. The key issue and challenges for extrusion-based bio-printing are also identified and discussed along with recommendations for future, aimed at developing novel biomaterials and bio-printing systems, creating patterned vascular networks within scaffolds, and preserving the cell viability and functions in scaffold bio-printing. The address of these challenges will significantly enhance the capability of extrusion-based bio-printing. Copyright © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Microbial conversion of biomass into bio-based polymers.

Science.gov (United States)

Kawaguchi, Hideo; Ogino, Chiaki; Kondo, Akihiko

2017-12-01

The worldwide market for plastics is rapidly growing, and plastics polymers are typically produced from petroleum-based chemicals. The overdependence on petroleum-based chemicals for polymer production raises economic and environmental sustainability concerns. Recent progress in metabolic engineering has expanded fermentation products from existing aliphatic acids or alcohols to include aromatic compounds. This diversity provides an opportunity to expand the development and industrial uses of high-performance bio-based polymers. However, most of the biomonomers are produced from edible sugars or starches that compete directly with food and feed uses. The present review focuses on recent progress in the microbial conversion of biomass into bio-based polymers, in which fermentative products from renewable feedstocks serve as biomonomers for the synthesis of bio-based polymers. In particular, the production of biomonomers from inedible lignocellulosic feedstocks by metabolically engineered microorganisms and the synthesis of bio-based engineered plastics from the biological resources are discussed.

A manual has been drafted by means of which it must be possible to determine whether materials, to be processed in a bio-energy project, is waste or biomass. The manual is based on national and international legislation and jurisprudence. [Dutch] Een handreiking is opgesteld om duidelijkheid te verkrijgen over de vraag wat afval is en wat biomassa is. Het antwoord op die vraag is uitgewerkt aan de hand van wetgeving en jurisprudentie, zowel nationaal als internationaal. Met enkele voorbeelden voor biomassa wordt praktisch dit toegelicht. Eenduidigheid in het onderscheid afval/niet-afval is van groot belang voor ieder bio-energieproject. Dit onderscheid kan grote consequenties hebben voor de inpassing in de ruimtelijke plannen, maar ook voor de vraag wie het bevoegd gezag is die de milieuvergunning uiteindelijk moet verlenen. In veel gevallen zijn bij bio-energieprojecten met afvalstoffen extra milieumaatregelen nodig die extra kosten met zich meebrengen Daarnaast moet de initiatiefnemer rekening houden met langere en meer gecompliceerde vergunningprocedures.

Recent Advances in the Sound Insulation Properties of Bio-based Materials

Directory of Open Access Journals (Sweden)

Xiaodong Zhu

2013-12-01

Full Text Available Many bio-based materials, which have lower environmental impact than traditional synthetic materials, show good sound absorbing and sound insulation performances. This review highlights progress in sound transmission properties of bio-based materials and provides a comprehensive account of various multiporous bio-based materials and multilayered structures used in sound absorption and insulation products. Furthermore, principal models of sound transmission are discussed in order to aid in an understanding of sound transmission properties of bio-based materials. In addition, the review presents discussions on the composite structure optimization and future research in using co-extruded wood plastic composite for sound insulation control. This review contributes to the body of knowledge on the sound transmission properties of bio-based materials, provides a better understanding of the models of some multiporous bio-based materials and multilayered structures, and contributes to the wider adoption of bio-based materials as sound absorbers.

Bio-based Industries Joint Undertaking: The catalyst for sustainable bio-based economic growth in Europe.

Mengal, Philippe; Wubbolts, Marcel; Zika, Eleni; Ruiz, Ana; Brigitta, Dieter; Pieniadz, Agata; Black, Sarah

2018-01-25

This article discusses the preparation, structure and objectives of the Bio-based Industries Joint Undertaking (BBI JU). BBI JU is a public-private partnership (PPP) between the European Commission (EC) and the Bio-based Industries Consortium (BIC), the industry-led private not-for-profit organisation representing the private sectors across the bio-based industries. The model of the public-private partnership has been successful as a new approach to supporting research and innovation and de-risking investment in Europe. The BBI JU became a reality in 2014 and represents the largest industrial and economic cooperation endeavour financially ever undertaken in Europe in the area of industrial biotechnologies. It is considered to be one of the most forward-looking initiatives under Horizon 2020 and demonstrates the circular economy in action. The BBI JU will be the catalyst for this strategy to mobilise actors across Europe including large industry, small and medium-sized enterprises (SMEs), all types of research organisations, networks and universities. It will support regions and in doing so, the European Union Member States and associated countries in the implementation of their bioeconomy strategies. Copyright © 2017 Elsevier B.V.

Liu, Lu; Ye, X Philip; Bozell, Joseph J

2012-07-01

Acrolein is an important chemical intermediate for many common industrial chemicals, leading to an array of useful end products. This paper reviews all the synthetic methods, including the former (aldol condensation) and contemporary (partial oxidation of propylene) manufacturing methods, the partial oxidation of propane, and most importantly, the bio-based glycerol-dehydration route. Emphasis is placed on the petroleum-based route from propylene and the bio-based route from glycerol, an abundantly available and relatively inexpensive raw material available from biodiesel production. This review provides technical details and incentives for industrial proyduction that justify a transition toward bio-based acrolein production. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.

Replacing fossil based plastic performance products by bio-based plastic products-Technical feasibility.

Science.gov (United States)

van den Oever, Martien; Molenveld, Karin

2017-07-25

Larger scale market introduction of new bio-based products requires a clear advantage regarding sustainability, as well as an adequate techno-economic positioning relative to fossil based products. In a previous paper [Broeren et al., 2016], LCA results per kg and per functionality equivalent of bio-based plastics were presented, together with economic considerations. The present paper discusses the mechanical and thermal properties of a range of commercially available bio-based plastics based on polylactic acid (PLA), cellulose esters, starch and polyamides, and the feasibility of replacing fossil-based counterparts based on performance. The evaluation is approached from an end user perspective. First, potentially suitable bio-based plastics are selected based on manufacturers' specifications in technical data sheets, then a first experimental evaluation is performed on injection moulded ISO specimens, and finally a further selection of plastics is tested on large 50×70cm panels. This technical feasibility study indicates that so far bio-based plastics do not completely match the properties of high performance materials like flame retardant V-0 PC/ABS blends used in electronic devices. The performance gap is being decreased by the development of stereocomplex PLA and hybrid PLA blends with polycarbonate, which offer clearly improved properties with respect to maximum usage temperature and toughness. In addition, several materials meet the V-0 flammability requirements needed in specific durable applications. On the other hand, improving these properties so far has negative consequences for the bio-based content. This study also shows that replacement of bulk polymers like PS is feasible using PLA compounds with a bio-based content as high as 85%. Copyright © 2016 Elsevier B.V. All rights reserved.

Determining the bio-based content of bio-plastics used in Thailand by radiocarbon analysis

Ploykrathok, T.; Chanyotha, S.

2017-06-01

Presently, there is an increased interest in the development of bio-plastic products from agricultural materials which are biodegradable in order to reduce the problem of waste disposal. Since the amount of modern carbon in bio-plastics can indicate how much the amount of agricultural materials are contained in the bio-plastic products, this research aims to determine the modern carbon in bio-plastic using the carbon dioxide absorption method. The radioactivity of carbon-14 contained in the sample is measured by liquid scintillation counter (Tri-carb 3110 TR, PerkinElmer). The percentages of bio-based content in the samples were determined by comparing the observed modern carbon content with the values contained in agricultural raw materials. The experimental results show that only poly(lactic acid) samples have the modern carbon content of 97.4%, which is close to the agricultural materials while other bio-plastics types are found to have less than 50% of the modern carbon content. In other words, most of these bio-plastic samples were mixed with other materials which are not agriculturally originated.

Processing and characterization of bio-based composites

Science.gov (United States)

Lu, Hong

Much research has focused on bio-based composites as a potential material to replace petroleum-based plastics. Considering the high price of Polyhydroxyalkanoates (PHAs), PHA/ Distiller's Dried Grains with Solubles (DDGS) composite is a promising economical and high-performance biodegradable material. In this paper, we discuss the effect of DDGS on PHA composites in balancing cost with material performance. Poly (lactic acid) PLA/DDGS composite is another excellent biodegradable composite, although as a bio-based polymer its degradation time is relatively long. The goal of this research is therefore to accelerate the degradation process for this material. Both bio-based composites were extruded through a twin-screw microcompounder, and the two materials were uniformly mixed. The morphology of the samples was examined using a Scanning Electron Microscope (SEM); thermal stability was determined with a Thermal Gravimetric Analyzer (TGA); other thermal properties were studied using Differential Scanning Calorimetry (DSC) and a Dynamic Mechanical Analyzer (DMA). Viscoelastic properties were also evaluated using a Rheometer.

The SER (Social and Economic Council of the Netherlands) Energy Agreement for Sustainable Growth outlines the ambition to provide a long-term perspective for the Dutch energy economy with short and medium term agreements. Therefore, a large number of concrete measures and elaborations are agreed upon. Quantitative assessments are made of the effects for 2020-2023. Because there are almost no concrete measures for a longer period and the uncertainties are increasing for the longer term, calculations were not carried out for years after 2023. The extent to which the agreed steps contribute to the necessary building blocks for the energy transition in the long term is assessed qualitatively. Agreed targets in the agreement are: (1) A reduction in final energy consumption by an average of 1.5% per year; (2) 100 PJ energy conservation in final energy consumption in 2020; (3) 14% renewable energy by 2020 and 16% in 2023; (4) at least 15,000 jobs with an emphasis on the next few years [Dutch] Het SER-Energieakkoord voor duurzame groei schetst als ambitie het bieden van een langetermijnperspectief voor onze energiehuishouding met afspraken voor de korte en middellange termijn. Het is daartoe een groot aantal concrete maatregelen en nadere uitwerkingen overeengekomen. ECN/PBL hebben met het EIB een kwantitatieve doorrekening gemaakt van de effecten voor 2020/23. Omdat er vrijwel geen concrete maatregelen zijn afgesproken die gericht zijn op een verder liggende periode en de onzekerheden op langere termijn steeds meer toenemen, is geen doorrekening voor latere jaren gemaakt. De mate waarin de afgesproken stappen bijdragen aan de nodige bouwstenen voor de energietransitie op langere termijn is kwalitatief beoordeeld. Afgesproken doelen in het akkoord zijn: (1) Een besparing van het finale energieverbruik met gemiddeld 1,5% per jaar; (2) 100 PJ besparing in het finale energieverbruik in 2020; (3) 14% hernieuwbare energie in 2020 en 16% in 2023; (4) Tenminste 15.000 banen met

Bio-Based Coatings for Paper Applications

Directory of Open Access Journals (Sweden)

Vibhore Kumar Rastogi

2015-11-01

Full Text Available The barrier resistance and wettability of papers are commonly controlled by the application of petroleum-based derivatives such as polyethylene, waxes and/or fluor- derivatives as coating. While surface hydrophobicity is improved by employing these polymers, they have become disfavored due to limitations in fossil-oil resources, poor recyclability, and environmental concerns on generated waste with lack of biodegradation. Alternatively, biopolymers including polysaccharides, proteins, lipids and polyesters can be used to formulate new pathways for fully bio-based paper coatings. However, difficulties in processing of most biopolymers may arise due to hydrophilicity, crystallization behavior, brittleness or melt instabilities that hinder a full exploitation at industrial scale. Therefore, blending with other biopolymers, plasticizers and compatibilizers is advantageous to improve the coating performance. In this paper, an overview of barrier properties and processing of bio-based polymers and their composites as paper coating will be discussed. In particular, recent technical advances in nanotechnological routes for bio-based nano- composite coatings will be summarized, including the use of biopolymer nanoparticles, or nanofillers such as nanoclay and nanocellulose. The combination of biopolymers along with surface modification of nanofillers can be used to create hierarchical structures that enhance hydrophobicity, complete barrier protection and functionalities of coated papers.

Bio-based Polymer Foam from Soyoil

Science.gov (United States)

Bonnaillie, Laetitia M.; Wool, Richard P.

2006-03-01

The growing bio-based polymeric foam industry is presently lead by plant oil-based polyols for polyurethanes and starch foams. We developed a new resilient, thermosetting foam system with a bio-based content higher than 80%. The acrylated epoxidized soybean oil and its fatty acid monomers is foamed with pressurized carbon dioxide and cured with free-radical initiators. The foam structure and pore dynamics are highly dependent on the temperature, viscosity and extent of reaction. Low-temperature cure hinds the destructive pore coalescence and the application of a controlled vacuum results in foams with lower densities ˜ 0.1 g/cc, but larger cells. We analyze the physics of foam formation and stability, as well as the structure and mechanical properties of the cured foam using rigidity percolation theory. The parameters studied include temperature, vacuum applied, and cross-link density. Additives bring additional improvements: nucleating agents and surfactants help produce foams with a high concentration of small cells and low bulk density. Hard and soft thermosetting foams with a bio content superior to 80% are successfully produced and tested. Potential applications include foam-core composites for hurricane-resistant housing, structural reinforcement for windmill blades, and tissue scaffolds.

SYNTHESIS AND CHARACTERIZATION OF BIO-BASED POLYESTER POLYOL

Directory of Open Access Journals (Sweden)

MİTHAT ÇELEBİ

2016-11-01

Full Text Available Polyurethanes are versatile polymeric materials and are usually synthesised by isocyanate reactions with polyols. Due to the variety of isocyanates and polyols, particularly polyols, polyurethanes can be easily tailored for wide applications, such as rigid and flexible foams, coatings, adhesives, and elastomers. Considerable efforts have been recently devoted to developing bio-based substitutes for petroleum-based polyuretahanes due to increasing concerns over the depletion of petroleum resources, environment, and sustainability. Polyester polyols based on aliphatic and aromatic dicarboxylic acids are one of the most important materials in polymer technologies. Large volume of plants oils are used as renewable resources to produce various chemicals which are industrially important to make soaps, cosmetic products, surfactants, lubricants, diluents, plasticizers, inks, agrochemicals, composite materials, food industry. This study introduces synthesis and properties of bio-based polyols from different renewable feedstocks including vegetable oils and derivatives. A comparison of bio-based polyol properties with their petroleum-based analogues were investigated.

Geothermal energy is too expensive to serve as energy supply for most horticultural entrepreneurs. Therefore, research has been carried out into options to use heat from more shallow layers (shallow geothermal energy). Unlike shallow geothermal energy deep geothermal energy can be applied on a smaller scale, possibly also for individual growers. It can be applied in combination with an existing heating system, but with a more sustainable outcome. Because drilling is done in shallow layers, drilling costs and financial risks are lower [Dutch] Geothermie is voor de meeste tuinbouwondernemers teduur om als energievoorziening te dienen. Daarom is onderzoek gedaan naar mogelijkheden om warmte te gebruiken uit ondiepere lagen (ondiepe geothermie). In tegenstelling tot diepe geothermie is ondiepe geothermie op kleinere schaal toepasbaar, mogelijk ook voor individuele kwekers. Het kan in combinatie met de bestaande verwarmingsinstallatie worden ingezet maar met een duurzamer resultaat. Omdat ondieper wordt geboord zijn de boorkosten en de financiele risico's lager.

Voor het verval. Belemmeringen en voorwaarden voor vroegsignalering en bewonersparticipatie

Directory of Open Access Journals (Sweden)

Vasco Lub

2009-12-01

Dit artikel onderzoekt de mogelijkheden van preventieve strategieën in het aanpakken van wijkverval en sociale onveiligheid. Gebaseerd op het vermoeden dat het broken windows-beleid doeltreffend kan zijn bij de aanpak van wijkverval, is een brochure met een lijst van 34 sociale en fysieke indicatoren ontwikkeld om bewoners en professionals te helpen bij het signaleren en aanpakken van tekens van verval. Door middel van een actieonderzoek in een aandachtswijk werd de bruikbaarheid van deze indicatoren onderzocht en werd in kaart gebracht welke factoren preventieve strategieën kunnen belemmeren, dan wel kunnen bevorderen. Het onderzoek toont aan dat verscheidene contextuele, bestuurlijke en bureaucratische factoren een belemmering vormen voor een effectieve preventieve aanpak. Daarbij kan onder andere gedacht worden aan: verschillen in verwachtingspatroon tussen bewoners en professionals; de manier waarop tekens van verval in de leefomgeving worden geïnterpreteerd door lokale actoren; de middelen waarmee frontliniewerkers in hun taakuitvoering worden toegerust; en het gebrek aan een verantwoordingswijze die gebaseerd is op het behalen van zichtbare resultaten. Voor het goed functioneren van een vroegtijdige aanpak van wijkverval, is het van groot belang dat lokale overheden een gemeenschappelijk perspectief ontwikkelen, de samenwerking tussen bewoners en professionals – en tussen professionals onderling – faciliteren, instanties aanspreken op resultaten en doelstellingen expliciteren om van overleg tot collectieve actie te komen.

De ontwikkeling van een met onderzoek onderbouwde methodiek voor het meidenwerk

both would seem to be valuable as means for making tacit knowledge explicit, and have the potential for solidifying, substantiating and transferring it. This is because they would act as guiding principles to provide direction for methodological action by social professionals in contact with the target group. They exist alongside each other and can be deployed according to the situation, goals, persons and resources available for the range of working methods, target groups, goals and contexts. SAMENVATTINGDe ontwikkeling van een met onderzoek onderbouwde methodiek voor het meidenwerkDit artikel doet verslag van een zoektocht naar de mogelijkheden voor het ontwikkelen van een met onderzoek onderbouwde methodiek voor het meidenwerk. Het geeft inzicht in de mogelijkheden en moeilijkheden voor het opbouwen van een kennisbasis voor open benaderingswijzen in de praktijk van het sociaal werk. De aanleiding is het verzoek van Amsterdamse meidenwerkers om hulp bij het ontwikkelen van een met onderzoek onderbouwde methodiek voor een bijna 90-jarige diverse en dynamische praktijk. De achtergrond vormt de discussie over de kennisbasis van het sociaal werk. Gangbare modellen als “evidence-based practice”, “practice-based evidence” en “common factors” worden besproken op geschiktheid voor het ontwikkelen van een met onderzoek onderbouwde methodiek voor open benaderingswijzen, waarna programma evaluatie als mogelijk alternatief wordt uitgediept. De conclusie is dat er vooral met betrekking tot open benaderingswijzen binnen het sociaal werk dringend meer aandacht nodig is voor het proces van methodiekontwikkeling en de wijze van onderbouwing. De eerste ervaringen met programma evaluatie en het daaruit voortvloeiende model van methodische principes zijn voorzichtig positief. Programma evaluatie lijkt handreikingen te bieden voor het omgaan met het spanningsveld tussen de wetenschappelijke kwaliteit van de bevindingen en de bruikbaarheid voor de praktijk. Methodische

Bio-Based Adhesives and Evaluation for Wood Composites Application

Directory of Open Access Journals (Sweden)

Fatemeh Ferdosian

2017-02-01

Full Text Available There has been a rapid growth in research and innovation of bio-based adhesives in the engineered wood product industry. This article reviews the recent research published over the last few decades on the synthesis of bio-adhesives derived from such renewable resources as lignin, starch, and plant proteins. The chemical structure of these biopolymers is described and discussed to highlight the active functional groups that are used in the synthesis of bio-adhesives. The potentials and drawbacks of each biomass are then discussed in detail; some methods have been suggested to modify their chemical structures and to improve their properties including water resistance and bonding strength for their ultimate application as wood adhesives. Moreover, this article includes discussion of techniques commonly used for evaluating the petroleum-based wood adhesives in terms of mechanical properties and penetration behavior, which are expected to be more widely applied to bio-based wood adhesives to better evaluate their prospect for wood composites application.

The bio-based economy relies on sustainable, plant-derived resources for fuels, chemicals, materials, food and feed rather than on the evanescent usage of fossil resources. The cornerstone of this economy is the biorefinery, in which renewable resources are intelligently converted to a plethora of products, maximizing the valorization of the feedstocks. Innovation is a prerequisite to move a fossil-based economy toward sustainable alternatives, and the viability of the bio-based economy depends on the integration between plant (green) and industrial (white) biotechnology. Green biotechnology deals with primary production through the improvement of biomass crops, while white biotechnology deals with the conversion of biomass into products and energy. Waste streams are minimized during these processes or partly converted to biogas, which can be used to power the processing pipeline. The sustainability of this economy is guaranteed by a third technology pillar that uses thermochemical conversion to valorize waste streams and fix residual carbon as biochar in the soil, hence creating a carbon-negative cycle. These three different multidisciplinary pillars interact through the value chain of the bio-based economy.

Developing a hybrid dictionary-based bio-entity recognition technique

Science.gov (United States)

2015-01-01

Background Bio-entity extraction is a pivotal component for information extraction from biomedical literature. The dictionary-based bio-entity extraction is the first generation of Named Entity Recognition (NER) techniques. Methods This paper presents a hybrid dictionary-based bio-entity extraction technique. The approach expands the bio-entity dictionary by combining different data sources and improves the recall rate through the shortest path edit distance algorithm. In addition, the proposed technique adopts text mining techniques in the merging stage of similar entities such as Part of Speech (POS) expansion, stemming, and the exploitation of the contextual cues to further improve the performance. Results The experimental results show that the proposed technique achieves the best or at least equivalent performance among compared techniques, GENIA, MESH, UMLS, and combinations of these three resources in F-measure. Conclusions The results imply that the performance of dictionary-based extraction techniques is largely influenced by information resources used to build the dictionary. In addition, the edit distance algorithm shows steady performance with three different dictionaries in precision whereas the context-only technique achieves a high-end performance with three difference dictionaries in recall.

2013-07-01

Funding will support the continuation of the Center for Advanced Bio-based Binders and Pollution Reduction Technology Center (CABB) in the development of bio-based polymers and emission reduction technologies for the metal casting industry. Since the formation of the center several new polymers based on agricultural materials have been developed. These new materials have show decreases in hazardous air pollutants, phenol and formaldehyde as much as 50 to 80% respectively. The polymers termed bio-polymers show a great potential to utilize current renewable agricultural resources to replace petroleum based products and reduce our dependence on importing of foreign oil. The agricultural technology has shown drastic reductions in the emission of hazardous air pollutants and volatile organic compounds and requires further development to maintain competitive costs and productivity. The project will also research new and improved inorganic binders that promise to eliminate hazardous emissions from foundry casting operations and allow for the beneficial reuse of the materials and avoiding the burdening of overcrowded landfills.

Engineering BioBrick vectors from BioBrick parts

Directory of Open Access Journals (Sweden)

Knight Thomas F

2008-04-01

Full Text Available Abstract Background The underlying goal of synthetic biology is to make the process of engineering biological systems easier. Recent work has focused on defining and developing standard biological parts. The technical standard that has gained the most traction in the synthetic biology community is the BioBrick standard for physical composition of genetic parts. Parts that conform to the BioBrick assembly standard are BioBrick standard biological parts. To date, over 2,000 BioBrick parts have been contributed to, and are available from, the Registry of Standard Biological Parts. Results Here we extended the same advantages of BioBrick standard biological parts to the plasmid-based vectors that are used to provide and propagate BioBrick parts. We developed a process for engineering BioBrick vectors from BioBrick parts. We designed a new set of BioBrick parts that encode many useful vector functions. We combined the new parts to make a BioBrick base vector that facilitates BioBrick vector construction. We demonstrated the utility of the process by constructing seven new BioBrick vectors. We also successfully used the resulting vectors to assemble and propagate other BioBrick standard biological parts. Conclusion We extended the principles of part reuse and standardization to BioBrick vectors. As a result, myriad new BioBrick vectors can be readily produced from all existing and newly designed BioBrick parts. We invite the synthetic biology community to (1 use the process to make and share new BioBrick vectors; (2 expand the current collection of BioBrick vector parts; and (3 characterize and improve the available collection of BioBrick vector parts.

Hydrogen is a clean fuel with very low emissions. In fuel cells the hydrogen can be converted to electricity with a high efficiency that can be used in electric transport and stationary applications. In order to promote and demonstrate this aspect ECN has investigated which applications Ecomare can use and demonstrate. Ecomare is the centre for Wadden and North Sea on Texel. The following options are investigated: Bicycles with fuel cells on hydrogen; Small utility vehicles with fuel cells on hydrogen; Back-up systems with fuel cells on hydrogen; Combined heat and power system with fuel cells on natural gas. The availability of transport systems with fuel cells is still small; from the bicycle market the cargobike from Masterflex is the best option. The cargobike will become available by mid 2009. The small utility vehicle that is potentially available is the VEM vehicle as developed in the Hychain project. For both vehicles the hydrogen logistic requires special attention since nonstandard hydrogen storage cylinders are used. For the stationary applications the demonstration aspect is less compared to the transport applications. The back-up systems are no necessity for Ecomare and the heat requirement in summertime is to small to for possible combined heat and power systems using fuel cells. Special attention is required for permits from the local authorities and fire department, and the transport of hydrogen by the ferry to Texel. [Dutch] Waterstof is bij gebruik een schone brandstof; er komen nauwelijks emissies bij vrij. Met behulp van brandstofcellen kan waterstof met een hoog rendement omgezet worden in elektriciteit, eventueel te gebruiken voor elektrisch vervoer. Om deze aspecten te promoten en tijdens het gebruik te laten zien wil Ecomare door ECN laten onderzoeken welke waterstoftoepassingen bij Ecomare ingezet kunnen worden. De volgende 4 opties zijn verder onderzocht: Fietsen met brandstofcellen op waterstof; Klein bedrijfsvoertuig met brandstofcellen

To increase the share of biomass for renewable energy in Europe conversion pathways which are economic, flexible in feedstock and energy efficient are needed. The BioBoost project concentrates on dry and wet residual biomass and wastes as feedstock for de-central conversion by fast pyrolysis, catalytic pyrolysis and hydrothermal carbonization to the intermediate energy carriers oil, coal or slurry. Based on straw the energy density increases from 2 to 20-30 GJ/m{sup 3}, enabling central GW scale gasification plants for bio-fuel production. A logistic model for feedstock supply and connection of de-central with central conversion is set up and validated allowing the determination of costs, the number and location of de-central and central sites. Techno/economic and environmental assessment of the value chain supports the optimization of products and processes. The utilization of energy carriers is investigated in existing and coming applications of heat and power production and synthetic fuels and chemicals. (orig.)

A new control strategy was developed based on the application of wireless sensor network with the connection to a smart grid to investigate if it is possible to save energy on the level of the user under the condition of maintaining the same or even improved level of individual comfort. By using different scenarios, for individual comfort and energy consumption, agents provide the steering of the process control This forms the basis of a new approach to optimize the energy consumption, after which the effect of it can be used on the level of residential building to optimize the interaction with the electrical infrastructure, the smart grid. [Dutch] Er vindt onderzoek plaats naar een nieuwe regelstrategie gebaseerd op de toepassing van een draadloos sensor netwerk dat is gekoppeld aan het smart grid. Doel van deze regelstrategie is om op gebruikersniveau energie te kunnen besparen met behoud of zelfs verbetering van het individueel comfort. Er zijn verschillende scenario's voor individueel comfort en energiegebruik van apparatuur met behulp van agents die voor de aansturing kunnen zorgen. Zo wordt de kern van de energievraag geoptimaliseerd. De doorwerking hiervan tot op het niveau van woninggebouw en de koppeling met het externe elektriciteitsnet kan vervolgens worden geoptimaliseerd.

2018-04-01

Full Text Available The use of biodegradable/bio-based polymers is of great importance in addressing several issues related to environmental protection, public health, and new, stricter legislation. Yet some applications require improved properties (such as barrier or mechanical properties, suggesting the use of nanosized fillers in order to obtain bio-based polymer nanocomposites. In this work, bionanocomposites based on two different biodegradable polymers (coming from the Bioflex and MaterBi families and two different nanosized fillers (organo-modified clay and hydrophobic-coated precipitated calcium carbonate were prepared and compared with traditional nanocomposites with high-density polyethylene (HDPE as matrix. In particular, the injection molding processability, as well as the mechanical and rheological properties of the so-obtained bionanocomposites were investigated. It was found that the processability of the two biodegradable polymers and the related nanocomposites can be compared to that of the HDPE-based systems and that, in general, the bio-based systems can be taken into account as suitable alternatives.

BioC is a simple XML format for text, annotations and relations, and was developed to achieve interoperability for biomedical text processing. Following the success of BioC in BioCreative IV, the BioCreative V BioC track addressed a collaborative task to build an assistant system for BioGRID curation. In this paper, we describe the framework of the collaborative BioC task and discuss our findings based on the user survey. This track consisted of eight subtasks including gene/protein/organism named entity recognition, protein-protein/genetic interaction passage identification and annotation visualization. Using BioC as their data-sharing and communication medium, nine teams, world-wide, participated and contributed either new methods or improvements of existing tools to address different subtasks of the BioC track. Results from different teams were shared in BioC and made available to other teams as they addressed different subtasks of the track. In the end, all submitted runs were merged using a machine learning classifier to produce an optimized output. The biocurator assistant system was evaluated by four BioGRID curators in terms of practical usability. The curators' feedback was overall positive and highlighted the user-friendly design and the convenient gene/protein curation tool based on text mining.Database URL: http://www.biocreative.org/tasks/biocreative-v/track-1-bioc/.

Impact of Bio-Based Plastics on Current Recycling of Plastics

Directory of Open Access Journals (Sweden)

Luc Alaerts

2018-05-01

Full Text Available Bio-based plastics are increasingly appearing in a range of consumption products, and after use they often end up in technical recycling chains. Bio-based plastics are different from fossil-based ones and could disturb the current recycling of plastics and hence inhibit the closure of plastic cycles, which is undesirable given the current focus on a transition towards a circular economy. In this paper, this risk has been assessed via three elaborated case studies using data and information retrieved through an extended literature search. No overall risks were revealed for bio-based plastics as a group; rather, every bio-based plastic is to be considered as a potential separate source of contamination in current recycling practices. For PLA (polylactic acid, a severe incompatibility with PET (polyethylene terephthalate recycling is known; hence, future risks are assessed by measuring amounts of PLA ending up in PET waste streams. For PHA (polyhydroxy alkanoate there is no risk currently, but it will be crucial to monitor future application development. For PEF (polyethylene furanoate, a particular approach for contamination-related issues has been included in the upcoming market introduction. With respect to developing policy, it is important that any introduction of novel plastics is well guided from a system perspective and with a particular eye on incompatibilities with current and upcoming practices in the recycling of plastics.

Waste cooking oil (WCO) is a kind of non-edible oil with enormous quantities and its unreasonable dispose may generate negative impact on human life and environment. However, WCO is certainly a renewable feedstock of bio-based materials. To get the rebirth of WCO, we have established a facile and high-yield method to convert WCO to bio-based zwitterionic surfactants with excellent surface and interfacial properties. The interfacial tension between crude oil and water could reach ultra-low value as 0.0016 mN m-1 at a low dosage as 0.100 g L-1 of this bio-based surfactant without the aid of extra alkali, which shows a strong interfacial activity and the great potential application in many industrial fields, in particular, the application in enhanced oil recovery in oilfields in place of petroleum-based surfactants.

Viscous Flow Behaviour of Karanja Oil Based Bio-lubricant Base Oil.

Sharma, Umesh Chandra; Sachan, Sadhana; Trivedi, Rakesh Kumar

2018-01-01

Karanja oil (KO) is widely used for synthesis of bio-fuel karanja oil methyl ester (KOME) due to its competitive price, good energy values and environmentally friendly combustion properties. Bio-lubricant is another value added product that can be synthesized from KO via chemical modification. In this work karanja oil trimethylolpropane ester (KOTMPE) bio-lubricant was synthesized and evaluated for its viscous flow behaviour. A comparison of viscous flow behaviours of natural KO and synthesized bio-fuel KOME and bio-lubricant KOTMPE was also made. The aim of this comparison was to validate the superiority of KOTMPE bio-lubricant over its precursors KO and KOME in terms of stable viscous flow at high temperature and high shear rate conditions usually encountered in engine operations and industrial processes. The free fatty acid (FFA) content of KO was 5.76%. KOME was synthesized from KO in a two-step, acid catalyzed esterification followed by base catalyzed transesterification, process at 65°C for 5 hours with oil-methanol ratio 1:6, catalysts H 2 SO 4 and KOH (1 and 1.25% w/w KO, respectively). In the final step, KOTMPE was prepared from KOME via transesterification with trimethylolpropane (TMP) at 150°C for 3 hours with KOME-TMP ratio 4:1 and H 2 SO 4 (2% w/w KOME) as catalyst. The viscosity versus temperature studies were made at 0-80°C temperatures in shear rate ranges of 10-1000 s -1 using a Discovery Hybrid Rheometer, model HR-3 (TA instruments, USA). The study found that viscosities of all three samples decreased with increase in temperature, though KOTMPE was able to maintain a good enough viscosity at elevated temperatures due to chemical modifications in its molecular structure. The viscosity index (VI) value for KOTMPE was 206.72. The study confirmed that the synthesized bio-lubricant KOTMPE can be used at high temperatures as a good lubricant, though some additives may be required to improve properties other than viscosity.

Bio-based products from solar energy and carbon dioxide.

Science.gov (United States)

Yu, Jian

2014-01-01

Producing bio-based products directly from CO₂ and solar energy is a desirable alternative to the conventional biorefining that relies on biomass feedstocks. The production paradigm is based on an artificial photosynthetic system that converts sunlight to electricity and H₂ via water electrolysis. An autotrophic H₂-oxidizing bacterium fixes CO₂ in dark conditions. The assimilated CO₂ is stored in bacterial cells as polyhydroxybutyrate (PHB), from which a range of products can be derived. Compared with natural photosynthesis of a fast-growing cyanobacterium, the artificial photosynthetic system has much higher energy efficiency and productivity of bio-based products. The new technology looks promising because of possible cost reduction in feedstock, equipment, and operation. Copyright © 2013 Elsevier Ltd. All rights reserved.

Geothermal energy is too expensive to serve as energy supply for most horticultural entrepreneurs. Therefore, research has been carried out into options to use heat from more shallow layers (shallow geothermal energy). Unlike shallow geothermal energy deep geothermal energy can be applied on a smaller scale, possibly also for individual growers. It can be applied in combination with an existing heating system, but with a more sustainable outcome. Because drilling is done in shallow layers, drilling costs and financial risks are lower. This report comprises the annexes (A) Geologic Framework, and (B) Maps of the Netherlands (depth, thickness of sand layers, temperature and shallow geothermal energy potential [Dutch] Geothermie is voor de meeste tuinbouwondernemers teduur om als energievoorziening te dienen.

In the 'Block by Block' project 13 local energy saving projects are supported in the development of concepts to realize large-scale energetic improvements of existing houses. In these projects the consortia develop strategies which are applied in the market. In addition, a number of projects is awarded with a so-called 'Green Deal' (agreements between governmental, public and private parties in the Netherlands). Part of the support is a knowledge and learning process. As part of the learning process a practice-oriented research has been carried out into the possibilities of database marketing (DBM) for energy conservation. The research focuses on the opportunities for DBM for energy savings and promising product-market combinations. The question is: can DBM contribute to improving the effectiveness of the 'Block by Block' projects?

2011-07-15

The Next Generation Cultivation has been developed as a system for horticultural production companies. For companies specialised in propagating plants, implementation of the Next Generation Cultivation is not necessarily straightforward. To make use of the experience and knowledge acquired in research from the energy programme Greenhouse as an Energy Source ('Kas als Energiebron') in these companies, analysis of the current situation and possible adaptations are required to tailor the Next Generation Cultivation for propagation nurseries. Within the project 'The Next Generation Cultivation for vegetable propagation' opportunities and pitfalls have been identified by means of 10 interviews, as well as a workshop and a short literature review. Based on the interviews, companies expect the biggest impact on reduction of energy use through: More extensive use of screening, Temperature integration, Forced ventilation. From the workshop it became apparent that the horizontal temperature profile especially needs to become more uniform and needs priority. If this is successful, it should be possible to obtain a reduction in energy use and a more uniform quality of starting plants simultaneously. Vegetable propagation production peaks between October and February. In the remaining months, the greenhouses are filled with other produce. The choices for crops with either low energy inputs ('cold vegetables' e.g. lettuce, cabbage, etc) or considerable energy inputs (various potplants) can be crucial in determining whether investments in energy savings can be economically viable [Dutch] Het Nieuwe Telen (HNT) is als systeem ontwikkeld voor de primaire productie bedrijven.

A new 100% bio-based thermosetting coating system was developed from epoxidized sucrose soyate crosslinked with blocked bio-based dicarboxylic acids. A solvent-free, green method was used to block the carboxylic acid groups and render the acids miscible with the epoxy resin. The thermal reversibility of this blocking allowed for the formulation of epoxy-acid thermoset coatings that are 100% bio-based. This was possible due to the volatility of the vinyl ethers under curing conditions. These systems have good adhesion to metal substrates and perform well under chemical and physical stress. Additionally, the hardness of the coating system is dependent on the chain length of the diacid used, making it tunable. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

BioPig: a Hadoop-based analytic toolkit for large-scale sequence data.

Nordberg, Henrik; Bhatia, Karan; Wang, Kai; Wang, Zhong

2013-12-01

The recent revolution in sequencing technologies has led to an exponential growth of sequence data. As a result, most of the current bioinformatics tools become obsolete as they fail to scale with data. To tackle this 'data deluge', here we introduce the BioPig sequence analysis toolkit as one of the solutions that scale to data and computation. We built BioPig on the Apache's Hadoop MapReduce system and the Pig data flow language. Compared with traditional serial and MPI-based algorithms, BioPig has three major advantages: first, BioPig's programmability greatly reduces development time for parallel bioinformatics applications; second, testing BioPig with up to 500 Gb sequences demonstrates that it scales automatically with size of data; and finally, BioPig can be ported without modification on many Hadoop infrastructures, as tested with Magellan system at National Energy Research Scientific Computing Center and the Amazon Elastic Compute Cloud. In summary, BioPig represents a novel program framework with the potential to greatly accelerate data-intensive bioinformatics analysis.

2016-06-01

The motivation for the BioHub project is to create an Integrated Knowledge Management System (IKMS) that will enable chemists to source ingredients from bio-renewables, rather than from non-sustainable sources such as fossil oil and its derivatives. The BioHubKB is the data repository of the IKMS; it employs Semantic Web technologies, especially OWL, to host data about chemical transformations, bio-renewable feedstocks, co-product streams and their chemical components. Access to this knowledge base is provided to other modules within the IKMS through a set of RESTful web services, driven by SPARQL queries to a Sesame back-end. The BioHubKB re-uses several bio-ontologies and bespoke extensions, primarily for chemical feedstocks and products, to form its knowledge organisation schema. Parts of plants form feedstocks, while various processes generate co-product streams that contain certain chemicals. Both chemicals and transformations are associated with certain qualities, which the BioHubKB also attempts to capture. Of immediate commercial and industrial importance is to estimate the cost of particular sets of chemical transformations (leading to candidate surfactants) performed in sequence, and these costs too are captured. Data are sourced from companies' internal knowledge and document stores, and from the publicly available literature. Both text analytics and manual curation play their part in populating the ontology. We describe the prototype IKMS, the BioHubKB and the services that it supports for the IKMS. The BioHubKB can be found via http://biohub.cs.manchester.ac.uk/ontology/biohub-kb.owl .

2010-01-01

This paper concerns the structural developments and the direction of technological change of the energy innovation system, based on the studies of Kuhn's model of scientific change and Schumpeter's model of technological change. The paper uses the case study of Thai government agencies for understanding the way governments can facilitate technological innovation. The analyses are based on a pre-foresight exercise to examine the potential of the bio-based energy and investigate a set of development policies necessary for the direction of energy system development. The results have shown that bio-based energy is seen as the next new wave for future businesses and one of the solutions to the problem of high oil prices to improve the world's economic security and sustainable development.

Hydrogen-powered road vehicles. Positive and negative health effects of new fuel; Waterstof in het wegverkeer. Voor- en nadelen voor de gezondheid van een nieuwe vorm van brandstof

Energy Technology Data Exchange (ETDEWEB)

NONE

2008-09-15

Because of the political, social and environmental problems associated with dependency on fossil fuels, there is considerable interest in alternative energy sources. Hydrogen is regarded as a promising option, particularly as a fuel for road vehicles. The Dutch Energy research Centre of the Netherlands (ECN) recently published a vision of the future, in which it suggested that by 2050 more than half of all cars in the Netherlands could be running on hydrogen. Assuming that the hydrogen is produced from renewable energy sources, migration to hydrogen-powered vehicles would also curb carbon dioxide emissions. In the United States, Japan and Europe, considerable public and private investment is therefore being made with a view to developing the technologies needed to make the creation of a hydrogen-based economy possible within a few decades. A switch to using hydrogen as the primary energy source for road vehicles would have far-reaching social consequences. As with all technological developments, opportunities would be created, but drawbacks would inevitably be encountered as well. Some of the disadvantages associated with hydrogen are already known, and are to some degree manageable. It is likely, however, that other drawbacks would come to light only once hydrogen-powered cars were actually in use With that thought in mind, and in view of the social significance of a possible transition to hydrogen, it was decided that the Health Council should assess the positive and negative effects that hydrogen use could have on public health. It is particularly important to make such an assessment at the present early stage in the development of hydrogen technologies, so that gaps in existing scientific knowledge may be identified and appropriate strategies may be developed for addressing such gaps. This report has been produced by the Health and Environment Surveillance Committee, which has special responsibility for the identification of important correlations between

Inexpensive non-sulfided Ni-based catalysts were evaluated for hydrotreatments using phenol as model compound. HZSM-5, a zeolite with different ratio of Si/Al and γ-Al(2)O(3) were impregnated with Ni(NO(3))(2) · 6H(2)O and calcined at 450 °C. Conversion rates and product distribution for treatment of phenol at 160-240 °C in the presence of catalysts with nickel loads of 6, 10, 14 and 17 wt.% were determined. Phenol conversion was highest (91.8%) at 240 °C in the presence of HZSM-5(Si/Al = 38) loaded with 10% Ni. When hydrotreatment was carried out with bio-oil obtained from pyrolysis of pine sawdust under the optimal conditions determined for phenol, the pH of bio-oil increased from 2.27 to 4.07, and the hydrogen content increased from 6.28 to 7.01 wt.%. The decrease in acidity is desirable for the use of upgraded bio-oil. Copyright © 2012. Published by Elsevier Ltd.

2010-01-01

Technical evaluation of Bio diesel, produced from various non-edible oils, was carried out on the basis of emission profile, torque, engine brake power and exhaust temperatures at 10% blend ratio (by volume) with mineral diesel. The performance of engine parameters showed that the castor oil based bio diesel gave the best results. Economic feasibility for bio diesel production was carried out based on available data on cultivation of necessary plants on marginal lands. This economic analysis also included the value of by-products which would be available during the chemical process for the production of bio diesel. It was found that jatropha bio diesel could be produced at a comparable cost to mineral diesel, however, castor bio diesel required substantial subsidies or mass cultivation of plants on marginal lands to enable it to compete economically with mineral diesel.

The introduction of biomass-derived compounds as an alternative feed into the refinery structure that already exists can potentially converge energy uses with ecological sustainability. Herein, we present an approach to produce a bio-oil based on carbohydrate-derived isopropylidene ketals obtained by reaction with acetone under acidic conditions directly from second-generation biomass. The obtained bio-oil showed a greater chemical inertness and miscibility with gasoil than typical bio-oil from fast pyrolysis. Catalytic upgrading of the bio-oil over zeolites (USY and Beta) yielded gasoline with a high octane number. Moreover, the co-processing of gasoil and bio-oil improved the gasoline yield and quality compared to pure gasoil and also reduced the amount of oxygenated compounds and coke compared with pure bio-oil, which demonstrates a synergistic effect. © 2014 WILEY-VCH Verlag GmbH & Co.

2012-04-01

Full Text Available In this paper a bio-based epoxy with outstanding thermal and mechanical properties was synthesized using a rosin-based epoxy monomer and a rosin-based curing agent. The chemical structures of rosin based epoxy monomer and curing agent were confirmed by Nuclear Magnetic Resonance (NMR and Fourier Transform Infrared (FT-IR spectra. The flexural mechanical and dynamic mechanical properties as well as thermal stability of the cured epoxy were investigated. The results showed that the cured epoxy exhibited a glass transition temperature (Tg of 164°C and its flexural strength and modulus were as high as 70 and 2200 MPa, respectively. This indicated that a wholly bio-based epoxy resin possessing high performance was successfully obtained.

Petrović, Zoran S; Milić, Jelena; Zhang, Fan; Ilavsky, Jan

2017-07-14

Novel fast response shape-memory polyurethanes were prepared from bio-based polyols, diphenyl methane diisocyanate and butane diol for the first time. The bio-based polyester polyols were synthesized from 9-hydroxynonanoic acid, a product obtained by ozonolysis of fatty acids extracted from soy oil and castor oil. The morphology of polyurethanes was investigated by synchrotron ultra-small angle X-ray scattering, which revealed the inter-domain spacing between the hard and soft phases, the degree of phase separation, and the level of intermixing between the hard and soft phases. We also conducted thorough investigations of the thermal, mechanical, and dielectric properties of the polyurethanes, and found that high crystallization rate of the soft segment gives these polyurethanes unique properties suitable for shape-memory applications, such as adjustable transition temperatures, high degree of elastic elongations, and good mechanical strength. These materials are also potentially biodegradable and biocompatible, therefore suitable for biomedical and environmental applications.

More chemistry between green and growth. The opportunities and dilemmas of a bio-based economy

International Nuclear Information System (INIS)

2010-12-01

A bio-based economy is one in which enterprises manufacture non-food products from biomass. Such products include fuel for the transport industry, chemicals, materials, and energy. Biomass is the biological material of living or recently living organisms, either animal or vegetable. With technology becoming more sophisticated, it is growing easier to turn plants, trees, crops, and residual animal waste into biomass. Waste and waste streams are increasingly being used as input in production processes, thereby gaining an economic value of their own. They are giving rise to new, sustainable products with considerable added value that replace products based on non-renewable materials. New bio-based products may offer the Netherlands new economic opportunities. The Dutch can already boast a number of distinct advantages in that respect, thanks to the sophistication of their industrial sector, agro-industry, chemicals and energy industries, and transport and logistics sector - all key sectors in a bio-based economy. However, the growing world population and increasing level of prosperity worldwide, and the environmental and climate problems associated with such growth, are adding to the complexity of policy-making aimed at developing a bio-based economy. The shift from fossil-based to bio-based materials must be part of a comprehensive policy aimed at achieving a sustainable economy. [nl

Zhang, Chen; Sun, Chao; Gao, Liqiang; Zheng, Nenggan; Chen, Weidong; Zheng, Xiaoxiang

2013-01-01

Bio-robots based on brain computer interface (BCI) suffer from the lack of considering the characteristic of the animals in navigation. This paper proposed a new method for bio-robots' automatic navigation combining the reward generating algorithm base on Reinforcement Learning (RL) with the learning intelligence of animals together. Given the graded electrical reward, the animal e.g. the rat, intends to seek the maximum reward while exploring an unknown environment. Since the rat has excellent spatial recognition, the rat-robot and the RL algorithm can convergent to an optimal route by co-learning. This work has significant inspiration for the practical development of bio-robots' navigation with hybrid intelligence.

Computational Methods to Assess the Production Potential of Bio-Based Chemicals.

2018-01-01

Elevated costs and long implementation times of bio-based processes for producing chemicals represent a bottleneck for moving to a bio-based economy. A prospective analysis able to elucidate economically and technically feasible product targets at early research phases is mandatory. Computational tools can be implemented to explore the biological and technical spectrum of feasibility, while constraining the operational space for desired chemicals. In this chapter, two different computational tools for assessing potential for bio-based production of chemicals from different perspectives are described in detail. The first tool is GEM-Path: an algorithm to compute all structurally possible pathways from one target molecule to the host metabolome. The second tool is a framework for Modeling Sustainable Industrial Chemicals production (MuSIC), which integrates modeling approaches for cellular metabolism, bioreactor design, upstream/downstream processes, and economic impact assessment. Integrating GEM-Path and MuSIC will play a vital role in supporting early phases of research efforts and guide the policy makers with decisions, as we progress toward planning a sustainable chemical industry.

The project Energy Efficient Scheduling of Pot Plant Production was aimed at developing and testing a decision support system for pot plant nurseries. The system allowed growers and consultants to compare the effects of changes in production schedules and climate settings on crop performance and energy requirement. The model-based scenario tool incorporated dynamic crop models for Euphorbia pulcherrima, Ficus benjamina and Hydrangea macrophylla, and the KASPRO model for greenhouse climate and energy balance. The system automatically acquired data from a local weather forecast service, real-time, web-based nursery-specific data acquisition systems and crop registration modules. Web-based data sharing also supported benchmarking between nurseries. The system was tested in field trials, involving four nurseries for each pot plant species. Improvements in energy efficiency of the production process resulted from optimized pot spacing schedules and from temperature strategies incorporating more prominent influences of the season, weather conditions and crop developmental phase [Dutch] In het kader van het project Energiezuinige Teeltplanning voor Potplanten is gewerkt aan een adviessysteem dat potplantentelers in staat stelt om zelfstandig de energie-efficientie van teeltscenario's te evalueren op basis van actuele, bedrijfsspecifieke gegevens.

Bio-based products are made from renewable materials, offering a promising basis for the production of sustainable chemicals, materials, and more complex articles. However, biomass is not a limitless resource or one without environmental and social impacts. Therefore, while it is important to use biomass and grow a bio-based economy, displacing the unsustainable petroleum basis of energy and chemical production, any resource must be used effectively to reduce waste. Standards have been developed to support the bio-based product market in order to achieve this aim. However, the design of bio-based products has not received the same level of attention. Reported here are the first steps towards the development of a framework of understanding which connects product design to resource efficiency. Research and development scientists and engineers are encouraged to think beyond simple functionality and associate value to the potential of materials in their primary use and beyond.

2011-01-01

The techno-economic potential of the UK poplar wood and imported oil palm empty fruit bunch derived bio-oil integrated gasification and Fischer-Tropsch (BOIG-FT) systems for the generation of transportation fuels and combined heat and power (CHP) was investigated. The bio-oil was represented in terms of main chemical constituents, i.e. acetic acid, acetol and guaiacol. The compositional model of bio-oil was validated based on its performance through a gasification process. Given the availability of large scale gasification and FT technologies and logistic constraints in transporting biomass in large quantities, distributed bio-oil generations using biomass pyrolysis and centralised bio-oil processing in BOIG-FT system are technically more feasible. Heat integration heuristics and composite curve analysis were employed for once-through and full conversion configurations, and for a range of economies of scale, 1 MW, 675 MW and 1350 MW LHV of bio-oil. The economic competitiveness increases with increasing scale. A cost of production of FT liquids of 78.7 Euro/MWh was obtained based on 80.12 Euro/MWh of electricity, 75 Euro/t of bio-oil and 116.3 million Euro/y of annualised capital cost. -- Highlights: → Biomass to liquid process and gas to liquid process synthesis. → Biorefinery economic analysis. → Pyrolysis oil to biofuel. → Gasification and Fischer-Tropsch. → Process integration, pinch analysis and energy efficiency.

The global bio-based chemical market is growing in size and importance. Bio-based solvents such as glycerol and 2-methyltetrahydrofuran are often discussed as important introductions to the conventional repertoire of solvents. However adoption of new innovations by industry is typically slow. Therefore it might be anticipated that neoteric solvent systems (e.g., ionic liquids) will remain niche, while renewable routes to historically established solvents will continue to grow in importance. This review discusses bio-based solvents from the perspective of their production, identifying suitable feedstocks, platform molecules, and relevant product streams for the sustainable manufacturing of conventional solvents.

Paint is used as a means of protection to prevent surfaces from being corroded over time. This research is focused on the development of a Bio-based paint made from palm oil methyl ester (POME) which originated from crude palm oil (CPO). New formulation paint has been developed to protect the pipeline from corrosion thus reducing the cost of the operation. Bio-based paint is made up of four components which are solvent, binder, additives, and pigment. The solvent in the bio-based paint is POME. The additives used are wetting and dispersing agent. The pigment used in the bio-based paint is TiO 2 . The formulation was developed by using a constant amount of additives and binder but varying the amount of POME at 10 ml, 15 ml, 20 ml, 25 ml and 30 ml with addition of water. The Standard Testing Methods for measuring the corrosion rate (ASTM G5-94(2011)) was carried out for each sample. In conclusion, it is proven that in the making of bio-based paint formulation for better corrosion inhibitor; the best amount of binder, additives and de-foam that should be used is 20 ml, 10 ml and 10 ml, respectively.

2017-10-01

Lignocellulosic biomass is an important feedstock for a potential future bio-based economy. Owing to its compact structure, suitable decomposition technologies will be necessary to make it accessible for biotechnological conversion. While chemical and enzymatic hydrolysis are currently established methods, a promising alternative is provided by fast pyrolysis. The main resulting product thereof, referred to as pyrolysis oil, is an energy-rich and easily transportable liquid. Many of the identified constituents of pyrolysis oil, however, have previously been reported to display adverse effects on microbial growth. In this Opinion we discuss relevant biological, biotechnological, and technological challenges that need to be addressed to establish pyrolysis oil as a reliable microbial feedstock for a bio-based economy of the future.

In recent years, the development of renewable bio-based resins has gained interest as potential replacements for petroleum based resins. Modified carbohydrate-based derivatives have favorable structural features such as fused bicyclic rings that offer promising candidates for the development of novel renewable polymers with improved thermomechanical properties when compared to early bio-based resins. Isosorbide is one such compound and has been utilized as the stiffness component for the synthesis of novel unsaturated polyesters (UPE) resins. Resin blends of BioUPE systems with styrene were shown to possess viscosities (120-2200 cP) amenable to a variety of liquid molding techniques, and after cure had Tgs (53-107 °C) and storage moduli (430-1650 MPa) that are in the desired range for composite materials. These investigations show that BioUPEs containing isosorbide can be tailored during synthesis of the prepolymer to meet the needs of different property profiles. Copyright © 2013 Elsevier Ltd.

Graphical abstract: - Highlights: • The (BiO)_2CO_3 with Aurivillius structure y is an emergent material. • Synthesis of (BiO)_2CO_3 micro/nano structures was reviewed. • The mechanisms of (BiO)_2CO_3 based nanocomposites were discussed. • Doping (BiO)_2CO_3 with nonmetals for enhanced activity was highlighted. • Multi-functional applications of (BiO)_2CO_3 based derivatives was demonstrated. - Abstract: (BiO)_2CO_3 (BOC), a fascinating material, belongs to the Aurivillius-related oxide family with an intergrowth texture in which Bi_2O_2"2"+ layers and CO_3"2"− layers are orthogonal to each other. BOC is a suitable candidate for various fields, such as healthcare, photocatalysis, humidity sensor, nonlinear optical application and supercapacitors. Recently, the photocatalysis properties of (BiO)_2CO_3 have been gained increased attention. BOC has a wide band gap (3.1–3.5 eV), which constrains its visible light absorption and utilization. In order to enhance the visible light driven photocatalytic performance of BOC, many modification strategies have been developed. According to the discrepancies of different coupling mechanisms, six primary systems of BOC-based nanocomposites can be classified and summarized: namely, metal/BOC heterojunction, single metal oxides (metal sulfides)/BOC heterostructure, bismuth-based metallic acid salts (Bi_xMO_y)/BOC, bismuth oxyhalides (BiOX)/BOC, metal-free semiconductor/BOC and the BOC-based complex heterojunction. Doping BOC with nonmetals (C, N and oxygen vacancy) is unique strategy and warrants a separate categorization. In this review, we first give a detailed description of the strategies to fabricate various BOC micro/nano structures. Next, the mechanisms of photocatalytic activity enhancement are elaborated in three parts, including BOC-based nanocomposites, nonmetal doping and formation of oxygen vacancy. The enhanced photocatalytic activity of BOC-based systems can be attributed to the unique interaction of

Ultra-sensitive bio-sensor based on GMR in self-suspended-membrane-type germanium grating

Ma, Jianyong; Zhang, Dawei

2012-01-01

In this paper, an ultra-sensitive bio-sensor based on the GMR effect in self-suspended-membrane-type gratings (SSGs) is proposed using multilayer plane waveguide theory. It is demonstrated from our calculations that the sensitivity of our bio-sensor is near the theoretical limit compared with a conventional GMR sensor. Based on the normalized eigenfunction of a single-layer homogeneous grating, the resonance curves with respect to different refractive indices of surrounding media are calculated, which confirm the estimated sensitivity. In addition, we design a highly sensitive bio-sensor in the near- and mid-IR wavelength region for liquid and gas detection respectively, the sensor can deliver a resolution over 1 × 10 −5 in the near-IR region in a large refractive index (1.3–1.7) range and provide better than 1 × 10 −6 in the mid-IR region, which is enough for various bio-material detections. Therefore, the bio-sensor we proposed is one or two orders more sensitive than conventional GMR sensors. (paper)

The goal of the project is make a rough estimate of the cost curve for 16 options for the medium term to improve the sustainability of the chain in the cement industry. In Chapter 2, the selection process of the sustainability options is described. Appendix A holds the list of options for the medium term. Next, the selected sustainability options are described of which CO2 emission reduction costs and CO2 emission reduction potentials are investigated. In Appendix B, the following aspects are described: ( a) the working principle of the measure (how does this measure contribute to the reduction of CO2 emission in the concrete chain?), (b) the reduction costs (how much are the costs for the reduction of 1 tonne CO2?, (c) the reduction potential (the amount of CO2 emissions that can be avoided on an annual basis, with the production in 2010 as the reference base)? In Chapter 3, the cost curve is presented: What are the reduction costs, What is the reduction potential, How sensitive are the data presented for variations in parameters? In Chapter 4 conclusions and recommendations are presented [Dutch] Het doel van het project is om een ruwe inschatting van de kostencurve op te stellen voor 16 opties voor de middellange termijn om de betonketen te verduurzamen.

Nannochloropsis algae pyrolysis with ceria-based catalysts for production of high-quality bio-oils.

Science.gov (United States)

Aysu, Tevfik; Sanna, Aimaro

2015-10-01

Pyrolysis of Nannochloropsis was carried out in a fixed-bed reactor with newly prepared ceria based catalysts. The effects of pyrolysis parameters such as temperature and catalysts on product yields were investigated. The amount of bio-char, bio-oil and gas products, as well as the compositions of the resulting bio-oils was determined. The results showed that both temperature and catalyst had significant effects on conversion of Nannochloropsis into solid, liquid and gas products. The highest bio-oil yield (23.28 wt%) and deoxygenation effect was obtained in the presence of Ni-Ce/Al2O3 as catalyst at 500°C. Ni-Ce/Al2O3 was able to retain 59% of the alga starting energy in the bio-oil, compared to only 41% in absence of catalyst. Lower content of acids and oxygen in the bio-oil, higher aliphatics (62%), combined with HHV show promise for production of high-quality bio-oil from Nannochloropsis via Ni-Ce/Al2O3 catalytic pyrolysis.

2015-01-01

A new formulation bio lubricant base stock was developed by blending of waste cooking oil (WCO) with Jatropha curcas oil (JCO). The objective of this research is to evaluate significant factors contributing to the production of oil blends for bio lubricant application. The significant factors used in this study were oil ratio (WCO:JCO), agitation times (min) and agitation speed (rpm). The blended oil bio based lubricant was used to determine the saponification, acid, peroxide and iodine values. The experimental design used in this study was the 2 level-factorial design. In this experiment, it was found that the effect of oil ratio and interaction of oil ratio and agitation speed gave the most significant effect in oil blends as bio lubricant base stock. The highest ratio of oil blend 80 %:20 % WCO:JCO, with low agitation speed of 300 rpm and low agitation time of 30 minutes gave the optimum results. The acid, saponification, peroxide and iodine values obtained were 0.517±0.08 mg KOH/ g, 126.23±1.62 mg/ g, 7.5±2.0 m eq/ kg and 50.42±2.85 mg/ g respectively. A higher ratio of waste cooking oil blends was found to be favourable as bio lubricant base stock. (author)

An overview is given of the market for wood wastes in the Netherlands and how this affects the targets to use biomass. Several types of biomass must be imported, not only wood wastes, but also e.g. olive stones and cacao shells. [Dutch] Er dreigt in Nederland een krapte te ontstaan op de markt voor afvalhout, want de vraag vanuit de buitenlandse vezelplaatindustrie blijft constant, terwijl er vanuit de energiesector een groeiende vraag is. Om de beleidsdoelstellingen voor biomassa te kunnen halen zal er biomassa geimporteerd moeten worden. Daarbij kan het gaan om resthout of afvalhout, maar ook om andere biomassastromen zoals olijfpitten en cacaodoppen.

This paper presents the prototype implementation of a Bio-Patch using fully integrated low-power System-on-Chip (SoC) sensor and paper-based inkjet printing technology. The SoC sensor is featured with programmable gain and bandwidth to accommodate a variety of bio-signals. It is fabricated in a 0.18-ìm standard CMOS technology, with a total power consumption of 20 ìW from a 1.2 V supply. Both the electrodes and interconnections are implemented by printing conductive nano-particle inks on a flexible photo paper substrate using inkjet printing technology. A Bio-Patch prototype is developed by integrating the SoC sensor, a soft battery, printed electrodes and interconnections on a photo paper substrate. The Bio-Patch can work alone or operate along with other patches to establish a wired network for synchronous multiple-channel bio-signals recording. The measurement results show that electrocardiogram and electromyogram are successfully measured in in-vivo tests using the implemented Bio-Patch prototype.

BioPortal: An Open-Source Community-Based Ontology Repository

Science.gov (United States)

Noy, N.; NCBO Team

2011-12-01

Advances in computing power and new computational techniques have changed the way researchers approach science. In many fields, one of the most fruitful approaches has been to use semantically aware software to break down the barriers among disparate domains, systems, data sources, and technologies. Such software facilitates data aggregation, improves search, and ultimately allows the detection of new associations that were previously not detectable. Achieving these analyses requires software systems that take advantage of the semantics and that can intelligently negotiate domains and knowledge sources, identifying commonality across systems that use different and conflicting vocabularies, while understanding apparent differences that may be concealed by the use of superficially similar terms. An ontology, a semantically rich vocabulary for a domain of interest, is the cornerstone of software for bridging systems, domains, and resources. However, as ontologies become the foundation of all semantic technologies in e-science, we must develop an infrastructure for sharing ontologies, finding and evaluating them, integrating and mapping among them, and using ontologies in applications that help scientists process their data. BioPortal [1] is an open-source on-line community-based ontology repository that has been used as a critical component of semantic infrastructure in several domains, including biomedicine and bio-geochemical data. BioPortal, uses the social approaches in the Web 2.0 style to bring structure and order to the collection of biomedical ontologies. It enables users to provide and discuss a wide array of knowledge components, from submitting the ontologies themselves, to commenting on and discussing classes in the ontologies, to reviewing ontologies in the context of their own ontology-based projects, to creating mappings between overlapping ontologies and discussing and critiquing the mappings. Critically, it provides web-service access to all its

From marine bio-corrosion to new bio-processes

International Nuclear Information System (INIS)

Bergel, A.; Dasilva, S.; Basseguy, R.; Feron, D.; Mollica, A.

2004-01-01

Full text of publication follows: From the middle of the last century it has been observed that the development of marine bio-films on the surface of stainless steels and different metallic materials induces the ennoblement of their free corrosion potential. A main step in deciphering the mechanisms of aerobic marine bio-corrosion has been achieved around 1976 with the demonstration that the potential ennoblement was due to the modification of the cathodic process. Since this date, the catalysis of oxygen reduction by marine bio-films has been the topic of numerous controversies, but it is now commonly agreed as a basic phenomena in aerobic corrosion. Several hypotheses have been proposed to explain the fine mechanisms of the bio-film-catalysed reduction of oxygen: intermediate formation of hydrogen peroxide, modification of the oxide layer on the stainless steel surface, involvement of manganese species and manganese oxidising bacteria, catalysis by proteins produced by the micro-organisms... Recent results may confirm the possible involvement of hemic enzymes or proteins. Whatever the mechanisms, very promising results have been obtained with the possible application of bio-film-catalysed oxygen reduction to conceive innovative biofuel cells with stainless steel electrodes. Actually, the catalysis of oxygen reduction is a key step that still drastically hinders the development of economically efficient hydrogen/oxygen fuel cells. The current technology requires high amounts of platinum or platinum-based materials to catalyze oxygen reduction on the cathode of these cells. The prohibitive cost of platinum is a main obstacle to the commercialization of low-cost fuel cells. Unpublished results recently showed that adapting the enzyme-catalysed reaction that was assumed for bio-corrosion on the cathode of hydrogen/oxygen fuel cells may lead to a significant decrease in the charge of platinum. Moreover, it was demonstrated on a laboratory-scale fuel cell pilot that

To be, or not to be biodegradable… that is the question for the bio-based plastics.

Science.gov (United States)

Prieto, Auxiliadora

2016-09-01

Global warming, market and production capacity are being the key drivers for selecting the main players for the next decades in the market of bio-based plastics. The drop-in bio-based polymers such as the bio-based polyethylene terephtalate (PET) or polyethylene (PE), chemically identical to their petrochemical counterparts but having a component of biological origin, are in the top of the list. They are followed by new polymers such as PHA and PLA with a significant market growth rate since 2014 with projections to 2020. Research will provide improved strains designed through synthetic and systems biology approaches; furthermore, the use of low-cost substrates will contribute to the widespread application of these bio- based polymers. The durability of plastics is not considered anymore as a virtue, and interesting bioprospecting strategies to isolate microorganisms for assimilating the recalcitrant plastics will pave the way for in vivo strategies for plastic mineralization. In this context, waste management of bio-based plastic will be one of the most important issues in the near future in terms of the circular economy. There is a clear need for standardized labelling and sorting instructions, which should be regulated in a coordinated way by policymakers and material producers. © 2016 The Author.

Choi, H.; Chang, C.; Savran, C.; Nolte, D.

2018-02-01

The BioCD platform technology uses spinning-disk interferometry to detect molecular binding to target molecular probes in biological samples. Interferometric configurations have included differential phase contrast and in-line quadrature detection. For the detection of extremely low analyte concentrations, nano- or microparticles can enhance the signal through background-free diffraction detection. Diffraction signal measurements on BioCD biosensors are achieved by forming gratings on a disc surface. The grating pattern was printed with biotinylated bovine serum albumin (BSA) and streptavidin coated beads were deployed. The diameter of the beads was 1 micron and strong protein bonding occurs between BSA and streptavidin-coated beads at the printed location. The wavelength for the protein binding detection was 635 nm. The periodic pattern on the disc amplified scattered light into the first-order diffraction position. The diffracted signal contains Mie scattering and a randomly-distributed-bead noise contributions. Variation of the grating pattern periodicity modulates the diffraction efficiency. To test multiple spatial frequencies within a single scan, we designed a fan-shaped grating to perform frequency filter multiplexing on a diffraction-based BioCD.

In this study we demonstrate the sensing capabilities of a portable multiplex measurement system for FET-based (bio)chemical sensors with an integrated microfluidic interface. We therefore conducted pH measurements with Silicon Nanoribbon FET-based Sensors using different measurement procedures that are suitable for various applications. We have shown multiplexed measurements in aqueous medium for three different modes that are mutually specialized in fast data acquisition (constant drain current), calibration-less sensing (constant gate voltage) and in providing full information content (sweeping mode). Our system therefore allows surface charge sensing for a wide range of applications and is easily adaptable for multiplexed sensing with novel FET-based (bio)chemical sensors.

This study investigates new intumescent formulations based on lignin and phosphinates to improve the flame retardant properties of Polyamide 11, while preserving the bio-based characteristics of this latter. Lignin has the advantage of being a bio-based compound and can be effectively used as carbon source for the design of intumescent systems in combination with other flame retardant additives. Metal phosphinates belong to a novel class of phosphorus flame retardants. Despite their increasing use, there is lack of scientific understanding as far as their fire retardancy mechanism is considered, especially in char forming polymeric materials. In this context, Polyamide 11 was melt blended with lignin and metal phosphinates. The possibility of melt spinning the prepared blends were assessed through melt flow index (MFI) tests; thermogravimetric (TG) analyses and cone calorimetry tests were exploited for investigating the thermal stability and the combustion behaviour of the obtained products, respectively. MFI results indicate that some formulations are suitable for melt spinning processes to generate flame retardant multifilament. Furthermore, the combination of lignin and phosphinates provides charring properties to polyamide 11. Finally, cone calorimetry data confirmed that the designed intumescent formulations could remarkably reduce PHRR through formation of protective char layer, hence slowing down the combustion process.

Background 7,8-Diaminopelargonic acid synthase (BioA), an enzyme of biotin biosynthesis pathway, is a well-known promising target for anti-tubercular drug development. Methods In this study, structure-based virtual screening was employed against the active site of BioA to identify new chemical entities for BioA inhibition and top ranking compounds were evaluated for their ability to inhibit BioA enzymatic activity. Results Seven compounds inhibited BioA enzymatic activity by greater than 60% at 100 μg/mL with most potent compounds being A36, A35 and A65, displaying IC50 values of 10.48 μg/mL (28.94 μM), 33.36 μg/mL (88.16 μM) and 39.17 μg/mL (114.42 μM), respectively. Compounds A65 and A35 inhibited Mycobacterium tuberculosis (M. tuberculosis) growth with MIC90 of 20 μg/mL and 80 μg/mL, respectively, whereas compound A36 exhibited relatively weak inhibition of M. tuberculosis growth (83% inhibition at 200 μg/mL). Compound A65 emerged as the most potent compound identified in our study that inhibited BioA enzymatic activity and growth of the pathogen and possessed drug-like properties. Conclusion Our study has identified a few hit molecules against M. tuberculosis BioA that can act as potential candidates for further development of potent anti-tubercular therapeutic agents.

[Dutch] In opdracht van de Milieufederaties van Drenthe Groningen en Friesland heeft CE een verkenning gedaan naar het energiegebruik van de ICT sector en nog belangrijker: naar de mogelijkheden om op dit energiegebruik te besparen. Tevens is gezocht naar enkele voorbeeldprojecten op het gebied van ICT en energiebesparing. Dit om communicatie en voorlichting rond energiebesparing kracht bij te kunnen zetten. Vanwege het hoge energiegebruik van datahotels en telecom switches is het voor deze bedrijven erg aantrekkelijk om energiebesparende maatregelen te treffen. Verder zouden ICT adviesbureaus een rol kunnen spelen in de overdracht van informatie over energiebesparende maatregelen aan andere kantoren. Hun besparingsadvies kan leiden tot significante kostenbesparingen, zoals bijvoorbeeld bij Server Based Computing (hoewel dit afhankelijk is van gekozen configuratie), het instellen van power management of vervanging van (afgeschreven) ICT apparatuur door efficientere varianten. Geinterviewden geven aan dat bij advies en aankoop van efficieente apparatuur behoefte bestaat aan Europese energielabels voor ICT en kantoorapparatuur, zoals die thans bestaan voor meerdere huishoudelijke apparaten.

Recently, a wider spectrum of bio-based materials and materials-based novel constructs and systems has been engineered with high interests. The key objective is to help for an enhanced/better quality of life in a secure way by avoiding/limiting various adverse effects of some in practice traditional therapies. In this context, different methodological approaches including in vitro, in vivo, and ex vivo techniques have been exploited, so far. Among them, bio-based therapeutic constructs are of supreme interests for an enhanced and efficient delivery in the current biomedical sector of the modern world. The development of new types of novel, effective and highly reliable materials-based novel constructs for multipurpose applications is essential and a core demand to tackle many human health related diseases. Bio-based materials possess several complementary functionalities, e.g. unique chemical structure, bioactivity, non-toxicity, biocompatibility, biodegradability, recyclability, etc. that position them well in the modern world's materials sector. In this context, the utilization of biomaterials provides extensive opportunities for experimentation in the field of interdisciplinary and multidisciplinary scientific research. With an aim to address the global dependence on petroleum-based polymers, researchers have been redirecting their interests to the engineering of biological materials for targeted applications in different industries including cosmetics, pharmaceuticals, and other biotechnological or biomedical applications. Herein, we reviewed biotechnological advancements at large and tissue engineering from a biomaterials perspective in particular and envision directions of future developments.

Applying distance-to-target weighing methodology to evaluate the environmental performance of bio-based energy, fuels, and materials

2007-01-01

The enhanced use of biomass for the production of energy, fuels, and materials is one of the key strategies towards sustainable production and consumption. Various life cycle assessment (LCA) studies demonstrate the great potential of bio-based products to reduce both the consumption of non-renewable energy resources and greenhouse gas emissions. However, the production of biomass requires agricultural land and is often associated with adverse environmental effects such as eutrophication of surface and ground water. Decision making in favor of or against bio-based and conventional fossil product alternatives therefore often requires weighing of environmental impacts. In this article, we apply distance-to-target weighing methodology to aggregate LCA results obtained in four different environmental impact categories (i.e., non-renewable energy consumption, global warming potential, eutrophication potential, and acidification potential) to one environmental index. We include 45 bio- and fossil-based product pairs in our analysis, which we conduct for Germany. The resulting environmental indices for all product pairs analyzed range from -19.7 to +0.2 with negative values indicating overall environmental benefits of bio-based products. Except for three options of packaging materials made from wheat and cornstarch, all bio-based products (including energy, fuels, and materials) score better than their fossil counterparts. Comparing the median values for the three options of biomass utilization reveals that bio-energy (-1.2) and bio-materials (-1.0) offer significantly higher environmental benefits than bio-fuels (-0.3). The results of this study reflect, however, subjective value judgments due to the weighing methodology applied. Given the uncertainties and controversies associated not only with distance-to-target methodologies in particular but also with weighing approaches in general, the authors strongly recommend using weighing for decision finding only as a

Amylose-only (AO, an engineered barley starch with 99% amylose, was tested to produce cross-linked all-natural bioplastic using normal barley starch as a control. Glycerol was used as plasticizer and citrate cross-linking was used to improve the mechanical properties of cross-linked AO starch extrudates. Extrusion converted the control starch from A-type to Vh- and B-type crystals, showing a complete melting of the starch crystals in the raw starch granules. The cross-linked AO and control starch specimens displayed an additional wide-angle diffraction reflection. Phospholipids complexed with Vh-type single helices constituted an integrated part of the AO starch specimens. Gas permeability tests of selected starch-based prototypes demonstrated properties comparable to that of commercial Mater-Bi© plastic. The cross-linked AO prototypes had composting characteristics not different from the control, indicating that the modified starch behaves the same as normal starch. The data shows the feasibility of producing all-natural bioplastic using designer starch as raw material.

This international comparative case study (the Netherlands, Germany, Sweden, United Kingdom) compares policy themes (household energy, food, mobility, household waste) and cases of interventions aims at more sustainable behaviours. It investigates how national policy can contribute to sustainable behaviour in these four themes. The study focuses on policy contexts and concrete 'best practice examples' (both policy -initiated and society-driven initiatives), paying attention to the extent to which social scientific insights have been utilised to conduct and evaluate the interventions. The conceptual approach in this study regards individual behaviour not in isolation but as embedded in institutional, social and physical contexts. In line with this, the evaluation of best practice examples focuses on how the following dimensions have been addressed in order to enable, support and sustain behavioural changes: the policy environment and institutional environment, individual behaviour, social norms a nd the physical environment. In this discussion, the Netherlands is both the starting point and the point of return, enabling us to draw lessons for Dutch policy. We conclude that a more proactive, dynamic and supportive role would fit national policy if it aims at encouraging the spread of more sustainable behaviours in society. Dutch policy could learn from the experiences of other countries and attempt at (among others): showing explicit commitment, connecting initiatives at different levels, and facilitating platforms for exchange of knowledge, experience and expertise, across sectors and departments, in order to arrive at a more integrated approach towards encouraging sustainable behaviours [Dutch] Als achtergrondstudie voor het advies Duurzame gedragspatronen zijn twee onderzoeken uitgevoerd naar effectief beleid voor duurzaam gedrag (1) in Nederland en (2) internationaal.

Cogeneration plants using bio fuel need a certificate in the Swedish electricity certificate system. Since the initiation of the system in 2003 the plants have taken advantage of the possibility of switching from fossil, to bio fuel. However, there is a potential for additional bio power production, provided that there is a market for the produced heating. The certificate system may contribute to an acceleration of investments in new capacities, and the facilitation of increased bio power production.

This paper presents the results of the comparative study of the parameters (chemical and physico-chemical modification, and hardening time affecting the physical (density, thermal conductivity coefficient and water-absorption behavior and mechanical properties (compressive strength of the bio-aggregate-based composite. A test of the parameters of the bio-composite samples showed some differences, which were determined by the chemical and surface properties of the modified filler, and which affected the mechanisms of hardening. The bulk density values of the hemp hurd composites hardened for 28 days place this material in the lightweight category of composites. The values of water absorption and the thermal conductivity coefficient of bio-composites decreased, and the strength parameter increased with an increase in the hardening time. The lower values of compressive strength, water absorption, and thermal conductivity coefficient (except for the ethylenediaminetetraacetic-acid-treated filler were observed in composites based on fillers chemically treated with NaOH and Ca(OH2 compared to referential composites (based on original hemp hurds. This is related to changes in the chemical composition of hemp hurds after chemical modification. The composites with ultrasound-treated hemp hurds had the greatest strengths at each hardening time. This is related to pulping the bundles of fibers and forming a larger surface area for bonding in the matrix.

The polymer industry is under pressure to mitigate the environmental cost of petrol-based plastics. Biotechnologies contribute to the gradual replacement of petrol-based chemistry and the development of new renewable products, leading to the closure of carbon circle. An array of bio-based building blocks is already available on an industrial scale and is boosting the development of new generations of sustainable and functionally competitive polymers, such as polylactic acid (PLA). Biocatalysts add higher value to bio-based polymers by catalyzing not only their selective modification, but also their synthesis under mild and controlled conditions. The ultimate aim is the introduction of chemical functionalities on the surface of the polymer while retaining its bulk properties, thus enlarging the spectrum of advanced applications.

Bio-oil based biorefinery strategy for the production of succinic acid

Science.gov (United States)

2013-01-01

Background Succinic acid is one of the key platform chemicals which can be produced via biotechnology process instead of petrochemical process. Biomass derived bio-oil have been investigated intensively as an alternative of diesel and gasoline fuels. Bio-oil could be fractionized into organic phase and aqueous phase parts. The organic phase bio-oil can be easily upgraded to transport fuel. The aqueous phase bio-oil (AP-bio-oil) is of low value. There is no report for its usage or upgrading via biological methods. In this paper, the use of AP-bio-oil for the production of succinic acid was investigated. Results The transgenic E. coli strain could grow in modified M9 medium containing 20 v/v% AP-bio-oil with an increase in OD from 0.25 to 1.09. And 0.38 g/L succinic acid was produced. With the presence of 4 g/L glucose in the medium, succinic acid concentration increased from 1.4 to 2.4 g/L by addition of 20 v/v% AP-bio-oil. When enzymatic hydrolysate of corn stover was used as carbon source, 10.3 g/L succinic acid was produced. The obtained succinic acid concentration increased to 11.5 g/L when 12.5 v/v% AP-bio-oil was added. However, it decreased to 8 g/L when 50 v/v% AP-bio-oil was added. GC-MS analysis revealed that some low molecular carbon compounds in the AP-bio-oil were utilized by E. coli. Conclusions The results indicate that AP-bio-oil can be used by E. coli for cell growth and succinic acid production. PMID:23657107

Gohar Nuhoff-Isakhanyan

2016-03-01

Full Text Available Bio-based businesses are often considered to be sustainable. However, they are also linked to sustainability challenges such as deforestation and soil erosion. Encouraged to exploit innovative solutions and enhance sustainability, organizations engaged in bio-based activities extensively explore collaboration possibilities with external partners. The objective of this paper is to integrate the available knowledge on sustainability of inter-organisational collaborations in bio-based businesses, while considering the three aspects of sustainability: environmental, economic, and social. We collected data from three academic sources—Web of Science, Scopus, and EconLit—and conducted a systematic literature review. The results show the importance of geographical proximity and complementarity in creating sustainability benefits such as reduced emissions, reduced waste, economic synergies, and socio-economic activities. Based on the findings, we have developed a framework that illustrates sustainability benefits and challenges. Interestingly, the studies emphasize sustainability benefits more in emerging than in industrialised economies, especially relating to the social aspects of sustainability. In conclusion, although the scholars have not discussed mitigation of several sustainability challenges in bio-based businesses, such as land use conflicts, they have found evidence of vital sustainability benefits, such as energy availability, lower emissions, improved socio-economic life, and poverty reduction, which are essential in emerging economies.

Comparative techno-economic analysis of biohydrogen production via bio-oil gasification and bio-oil reforming

International Nuclear Information System (INIS)

Zhang, Yanan; Brown, Tristan R.; Hu, Guiping; Brown, Robert C.

2013-01-01

This paper evaluates the economic feasibility of biohydrogen production via two bio-oil processing pathways: bio-oil gasification and bio-oil reforming. Both pathways employ fast pyrolysis to produce bio-oil from biomass stock. The two pathways are modeled using Aspen Plus ® for a 2000 t d −1 facility. Equipment sizing and cost calculations are based on Aspen Economic Evaluation® software. Biohydrogen production capacity at the facility is 147 t d −1 for the bio-oil gasification pathway and 160 t d −1 for the bio-oil reforming pathway. The biomass-to-fuel energy efficiencies are 47% and 84% for the bio-oil gasification and bio-oil reforming pathways, respectively. Total capital investment (TCI) is 435 million dollars for the bio-oil gasification pathway and is 333 million dollars for the bio-oil reforming pathway. Internal rates of return (IRR) are 8.4% and 18.6% for facilities employing the bio-oil gasification and bio-oil reforming pathways, respectively. Sensitivity analysis demonstrates that biohydrogen price, biohydrogen yield, fixed capital investment (FCI), bio-oil yield, and biomass cost have the greatest impacts on facility IRR. Monte-Carlo analysis shows that bio-oil reforming is more economically attractive than bio-oil gasification for biohydrogen production. -- Highlights: ► Biohydrogen production via bio-oil reforming has higher energy efficiency compared to gasification. ► Hydrogen price, fixed capital cost, and feedstock cost most strongly affect IRR. ► Lower risk investment is biohydrogen production via bio-oil reforming

Design and Fabrication of Piezoresistive Based Encapsulated Poly-Si Cantilevers for Bio/chemical Sensing

Krishna, N. P. Vamsi; Murthy, T. R. Srinivasa; Reddy, K. Jayaprakash; Sangeeth, K.; Hegde, G. M.

Cantilever-based sensing is a growing research field not only within micro regime but also in nano technology. The technology offers a method for rapid, on-line and in-situ monitoring of specific bio/chemical substances by detecting the nanomechanical responses of a cantilever sensor. Cantilever with piezoresistive based detection scheme is more attractive because of its electronics compatibility. Majority of commercially available micromachined piezoresistive sensors are bulk micromachined devices and are fabricated using single crystal silicon wafers. As substrate properties are not important in surface micromachining, the expensive silicon wafers can be replaced by cheaper substrates, such as poly-silicon, glass or plastic. Here we have designed SU-8 based bio/chemical compatible micro electro mechanical device that includes an encapsulated polysilicon piezoresistor for bio/chemical sensing. In this paper we report the design, fabrication and analysis of the encapsulated poly-Si cantilevers. Design and theoretical analysis are carried out using Finite Element Analysis software. For fabrication of poly-silicon piezoresistive cantilevers we followed the surface micromachining process steps. Preliminary characterization of the cantilevers is presented.

Advertenties voor hypnotica en sedativa in het Nederlands Tijdschrift voor Geneeskunde, 1900-1940: historische veranderingen in de vorm en inhoud van een informatiebron voor artsen

Full Text Available Drug advertising as communication between the pharmaceutical industry and the physician: Advertisements for psychotropic drugs in the Dutch medical journal, Nederlands Tijdschrift voor Geneeskunde, 1900-1940   In this article we explore the historical development of drug advertisements for psychotropic drugs in the leading Dutch medical journal from 1900 to 1940. The advertisements for hypnotics and sedatives, in the Nederlands Tijdschrift voor Geneeskunde (Dutch medical journal reflected the changes in the vocabulary and image promoted by the pharmaceutical companies. In the first two decades, the advertisements were sober and to the point, and included the trademark, company name, molecular formula and therapeutic properties of the medication. The emphasis was on creating a scientific image of reliable symptom control for the therapeutic drug. In doing so, the ethical drug companies tried (successfully to distinguish themselves from the producers of patent medicines. Once scientific credibility was established, the form and content of the advertisements changed significantly. In the late 1920s and 1930s drug companies embraced modern advertising techniques, developing a figurative language to address the changing beliefs and practices of Dutch physicians. Instead of promoting therapeutic drugs as safe and scientific, the emphasis was on their effectiveness in comparison to similar drugs. In the process, scientific information was reduced to an indispensable standardized minimum, whereby therapeutic drugs were advertised according to the latest pharmacological taxonomy rather than molecular formulas. The image-making of ‘ethical marketing’ began during the interwar years when marketers applied modern advertising techniques and infotainment strategies. The scanty black and white informational bulletins transitioned into colourful advertisements. The pharmaceutical companies employed the same medical language as used by physicians, so that

Ontology-Based Querying with Bio2RDF's Linked Open Data.

A key activity for life scientists in this post "-omics" age involves searching for and integrating biological data from a multitude of independent databases. However, our ability to find relevant data is hampered by non-standard web and database interfaces backed by an enormous variety of data formats. This heterogeneity presents an overwhelming barrier to the discovery and reuse of resources which have been developed at great public expense.To address this issue, the open-source Bio2RDF project promotes a simple convention to integrate diverse biological data using Semantic Web technologies. However, querying Bio2RDF remains difficult due to the lack of uniformity in the representation of Bio2RDF datasets. We describe an update to Bio2RDF that includes tighter integration across 19 new and updated RDF datasets. All available open-source scripts were first consolidated to a single GitHub repository and then redeveloped using a common API that generates normalized IRIs using a centralized dataset registry. We then mapped dataset specific types and relations to the Semanticscience Integrated Ontology (SIO) and demonstrate simplified federated queries across multiple Bio2RDF endpoints. This coordinated release marks an important milestone for the Bio2RDF open source linked data framework. Principally, it improves the quality of linked data in the Bio2RDF network and makes it easier to access or recreate the linked data locally. We hope to continue improving the Bio2RDF network of linked data by identifying priority databases and increasing the vocabulary coverage to additional dataset vocabularies beyond SIO.

Large-proportional shrunken bio-replication of shark skin based on UV-curing shrinkage

International Nuclear Information System (INIS)

Chen, Huawei; Che, Da; Zhang, Xin; Yue, Yue; Zhang, Deyuan

2015-01-01

The shark skin effect has attracted worldwide attention because of its superior drag reduction. As the product of natural selection, the maximum drag reduction of shark skin is found in its normal living environment. Large-proportional shrinkage of shark skin morphology is greatly anticipated for its adaptation to faster fluid flow. One novel approach, large-proportional shrunken bio-replication, is proposed as a method to adjust the optimal drag reduction region of shark skin based on the shrinkage of UV-cured material. The shark skin is taken as a replica template to allow large-proportional shrinking in the drag reduction morphology by taking advantage of the shrinkage of UV-curable material. The accuracy of the large-proportional shrunken bio-replication approach is verified by a comparison between original and shrunken bio-replicated shark skin, which shows that the shrinking ratio can reach 23% and the bio-replication accuracy is higher than 95%. In addition, the translation of the optimum drag reduction peak of natural surface function to various applications and environments is proved by drag reduction experiments. (technical note)

In this study, bio-oil from the fast pyrolysis of renewable biomass was used as the raw material to synthesize bio-oil phenol formaldehyde (BPF) resin-a desirable resin for fabricating phenolic-based material. During the synthesis process, paraformaldehyde was used to achieve the requirement of high solid content and low viscosity. The properties of BPF resins were tested. Results indicated that BPF resin with the bio-oil addition of 20% had good performance on oxygen index and bending strength, indicating that adding bio-oil could modify the fire resistance and brittleness of PF resin. The thermal curing behavior and heat resistance of BPF resins were investigated by differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA). Results showed that adding bio-oil had an impact on curing characteristics and thermal degradation process of PF resin, but the influence was insignificant when the addition was relatively low. The chemical structure and surface characteristics of BPF resins were determined by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The analysis demonstrated that adding bio-oil in the amount of 20% was able to improve the crosslinking degree and form more hydrocarbon chains in PF resin.

We explored the combination of nanoclay with new chemically functionalized, amphiphilic, plant oil resins to form bio-based nanocomposites with improved physical and mechanical properties. These can be used in many new applications, including the development of self-healing nanocomposites through controlled reversible exfoliation/intercalation, and self-assembled nano-structures. Several chemically modified triglyceride monomers of varying polarity, combined with styrene (ca 30include acrylated epoxidized soybean oil (AESO), maleated acrylated epoxidized soybean oil (MAESO) and soybean oil pentaerythritol glyceride maleates (SOPERMA), containing either hydroxyl group or acid functionality or both. The clay used is a natural montmorillonite modified with methyl tallow bis-2-hydroxyethyl quaternary ammonium chloride, which has hydroxyl groups. Both XRD and TEM showed a completely exfoliated structure at 3 wtwhen the clay content is above 5 wtconsidered a mix of intercalated and partially exfoliated structure. The controlled polarity of the monomer has a major effect on the reversible dispersion of clay in the polymer matrix. The bio-based nanocomposites showed a significant increase in flexural modulus and strength. Supported by EPA and DoE

2017-04-01

When surveying the trends and criteria for the design for recycling (DfR) of bio-based polymers, priorities appear to lie in energy recovery at the end of the product life of durable products, such as bio-based thermosets. Non-durable products made of thermoplastic polymers exhibit good properties for material recycling. The latter commonly enjoy growing material recycling quotas in countries that enforce a landfill ban. Quantitative and qualitative indicators are needed for characterizing progress in the development towards more recycling friendly bio-based polymers. This would enable the deficits in recycling bio-based plastics to be tracked and improved. The aim of this paper is to analyse the trends in the DfR of bio-based polymers and the constraints posed by the recycling infrastructure on plastic polymers from a systems perspective. This analysis produces recommendations on how life cycle assessment indicators can be introduced into the dialogue between designers and recyclers in order to promote DfR principles to enhance the cascading use of bio-based polymers within the bioeconomy, and to meet circular economy goals.

Chitin based polyurethane bio-nanocomposites (PUBNC) were prepared using chitin, Delite HPS bentonite nanoclay enriched in montmorillonite (MMT), 4,4'-diphenylmethane diisocyanate (MDI) and polycaprolactone polyol CAPA 231 (3000 g/mol(-1)). The prepolymers having different concentration of Delite HPS bentonite nanoclay were extended with 2 moles of chitin. The structures of the resulted polymers were determined by FT-IR technique. The effect of nanoclay contents on mechanical properties and in vitro biocompatibility was investigated. The mechanical properties of the synthesized materials were improved with increase in the Delite HPS bentonite nanoclay contents. Optimum mechanical properties were obtained from the PU bio-nanocomposite samples having 4% Delite HPS bentonite nanoclay. The results revealed that the final PU bio-nanocomposite having 2% Delite HPS bentonite nanoclay contents is ideal contenders for surgical threads with on going investigations into their in vitro biocompatibility, non-toxicity, and mechanical properties.

Polyvinylpyrrolidone-Based Bio-Ink Improves Cell Viability and Homogeneity during Drop-On-Demand Printing

Directory of Open Access Journals (Sweden)

Wei Long Ng

2017-02-01

Full Text Available Drop-on-demand (DOD bioprinting has attracted huge attention for numerous biological applications due to its precise control over material volume and deposition pattern in a contactless printing approach. 3D bioprinting is still an emerging field and more work is required to improve the viability and homogeneity of printed cells during the printing process. Here, a general purpose bio-ink was developed using polyvinylpyrrolidone (PVP macromolecules. Different PVP-based bio-inks (0%–3% w/v were prepared and evaluated for their printability; the short-term and long-term viability of the printed cells were first investigated. The Z value of a bio-ink determines its printability; it is the inverse of the Ohnesorge number (Oh, which is the ratio between the Reynolds number and a square root of the Weber number, and is independent of the bio-ink velocity. The viability of printed cells is dependent on the Z values of the bio-inks; the results indicated that the cells can be printed without any significant impairment using a bio-ink with a threshold Z value of ≤9.30 (2% and 2.5% w/v. Next, the cell output was evaluated over a period of 30 min. The results indicated that PVP molecules mitigate the cell adhesion and sedimentation during the printing process; the 2.5% w/v PVP bio-ink demonstrated the most consistent cell output over a period of 30 min. Hence, PVP macromolecules can play a critical role in improving the cell viability and homogeneity during the bioprinting process.

BioGPS descriptors for rational engineering of enzyme promiscuity and structure based bioinformatic analysis.

Directory of Open Access Journals (Sweden)

Valerio Ferrario

Full Text Available A new bioinformatic methodology was developed founded on the Unsupervised Pattern Cognition Analysis of GRID-based BioGPS descriptors (Global Positioning System in Biological Space. The procedure relies entirely on three-dimensional structure analysis of enzymes and does not stem from sequence or structure alignment. The BioGPS descriptors account for chemical, geometrical and physical-chemical features of enzymes and are able to describe comprehensively the active site of enzymes in terms of "pre-organized environment" able to stabilize the transition state of a given reaction. The efficiency of this new bioinformatic strategy was demonstrated by the consistent clustering of four different Ser hydrolases classes, which are characterized by the same active site organization but able to catalyze different reactions. The method was validated by considering, as a case study, the engineering of amidase activity into the scaffold of a lipase. The BioGPS tool predicted correctly the properties of lipase variants, as demonstrated by the projection of mutants inside the BioGPS "roadmap".

This international comparative case study (the Netherlands, Germany, Sweden, United Kingdom) compares policy themes (household energy, food, mobility, household waste) and cases of interventions aims at more sustainable behaviours. It investigates how national policy can contribute to sustainable behaviour in these four themes. The study focuses on policy contexts and concrete 'best practice examples' (both policy -initiated and society-driven initiatives), paying attention to the extent to which social scientific insights have been utilised to conduct and evaluate the interventions. The conceptual approach in this study regards individual behaviour not in isolation but as embedded in institutional, social and physical contexts. In line with this, the evaluation of best practice examples focuses on how the following dimensions have been addressed in order to enable, support and sustain behavioural changes: the policy environment and institutional environment, individual behaviour, social norms a nd the physical environment. In this discussion, the Netherlands is both the starting point and the point of return, enabling us to draw lessons for Dutch policy. We conclude that a more proactive, dynamic and supportive role would fit national policy if it aims at encouraging the spread of more sustainable behaviours in society. Dutch policy could learn from the experiences of other countries and attempt at (among others): showing explicit commitment, connecting initiatives at different levels, and facilitating platforms for exchange of knowledge, experience and expertise, across sectors and departments, in order to arrive at a more integrated approach towards encouraging sustainable behaviours [Dutch] Als achtergrondstudie voor het advies Duurzame gedragspatronen zijn twee onderzoeken uitgevoerd naar effectief beleid voor duurzaam gedrag (1) in Nederland en (2) internationaal.

Swimming pools are public buildings. Generally, the local authorities are responsible for their housing. New constructions or renovations are usually based on high ambitions for environmental conservation, partly because no other building uses as much energy as a swimming pool. [Dutch] Een zwembad is een publiek gebouw. Meestal is de gemeentelijke overheid verantwoordelijk voor de huisvesting. Bij nieuwbouw of renovatie zijn de ambities met betrekking tot milieubesparing vaak hoog, mede omdat bijna geen enkel gebouw is zo energie-intensief als een zwembad.

The production of bioenergy in the Netherlands is stimulated by policies at both the national and European levels. But energy from biomass is not by definition sustainable. And despite serious global consequences for food production and biodiversity, for example, continuing growth in world bio-energy demand is inevitable. Amid fears that rising demand for biomass will put soils under increasing pressure and cause further degradation of poorly managed land, the Technical committee on soil protection (TCB) commissioned a research study into the potential positive and negative effects of bioenergy on land use and soil quality in the Netherlands. The production of energy from biomass can follow a number of possible routes (electricity, heat and transport fuel) and use various organic feedstocks (energy crops, by-products and imported biomass). Study of the development of these supply chains and their biomass demands reveals that they largely reflect the technological potential and supply of biomass. The bioenergy sector is currently debating sustainability issues, but this includes little consideration of the soil. An assessment framework has been drawn up to appraise the effects of bioenergy on land use and soil quality in the Netherlands. It is based on a conceptual model of the 'sustainability of bioenergy' and a review of soil quality indicators (such as land use/landscape, biodiversity, organic matter, nutrient supply, mineral surpluses, soil structure, bioremediation and soil pollution). The illustration depicts the research questions as interpreted in this study. A subsequent appraisal focused on the organic matter balance at the field and regional levels. Use of the assessment framework is illustrated for the 'green electricity' and 'transport biofuels' chains, with a qualitative evaluation for the indicators organic matter, minerals and land use. From the first appraisal made using the assessment framework we conclude that

Bio-based polyurethane (PU) composite foams filled with various inorganic fillers, such as barium sulfate (BaSO 4 ), calcium carbonate (CaCO 3 ) and talc were prepared using polyols, such as diethylene glycol, triethylene glycol and polyethylene glycol (molecular weight ca. 200) containing molasses and lignin. Reactive hydroxyl groups in plant components and above polyols were used as reaction sites. Morphological observation of fracture surface of composites was carried out by scanning electron microscopy. Thermal properties of bio-based PU composites were examined by thermogravimetry. It was found that the above composites decompose in two stages reflecting decomposition of organic components. Decomposition temperature increased with increasing filler content, when plant components were homogenously mixed with inorganic fillers. Activation energy calculated by Ozawa-Wall-Flynn method was ca. 150 kJ mol -1 . The durability of composites was predicted using kinetic data. Calculated values indicate that composites with fillers are more durable than that of those without fillers at a moderate temperature region

The paper is based on the ESTO Study: Techno- Economic Feasibility of Large-Scale Production of Bio-Fuels in EU-Candidate Countries. Bio-fuel production has not been taken into account significantly until now in Romania, being limited to small- scale productions of ethanol, used mostly for various industrial purposes. However the climatic conditions and the quality of the soil are very suitable in the country for development of the main crops (wheat, sugar-beet, sunflower and rape-seed) used in bio-ethanol and bio-diesel production. The paper intended to consider a pertinent discussion of the present situation in Romania's agriculture stressing on the following essential items in the estimation of bio-fuels production potential: availability of feed-stock for bio-fuel production; actual productions of bio-fuels; fuel consumption; cost assessment; SWOT approach; expected trends. Our analysis was based on specific agricultural data for the period 1996-2000. An important ethanol potential (due to wheat, sugar-beet and maize cultures), as well as bio-diesel one (due to sun-flower and rape-seed) were predicted for the period 2005-2010 which could be exploited with the support of an important financial and technological effort, mainly from EU countries

The results of a study on using new information and communication technology in small-scale energy management systems on the level of individual households are presented. Detailed requirements are formulated for such an energy management system. A hardware and software architecture is proposed based on existing standards for delivering service applications. A large part of the energy management functionality for such a E-box for energy efficiency and cost control has been implemented in a software prototype. The results of prototype simulation studies indicate that there is a cost saving potential and a potential for improved embedding of small scale, sustainable energy generators, if operations of appliances are co-ordinated in view of real-time market price signals. The potential (spread in cost plus or minus 15%) is highest for combined operation of small micro-CHP (Stirling motor powered or fuel cell installations) satisfying a house's heat demand with laundry washing and drying processes in a real time electricity pricing situation. A similar increase in cost effectiveness can be achieved, if buffering of energy-carriers (electricity or heat) is used. Possible market and business models for implementing the functionality of an E-box are dealt with and some possible implementation opportunities in a real-time price liberalised end user energy consumption market are discussed.

Here we report a BioMEMS based microfluidic device as a deformation assay to study the deformability and growth capability of cells through microgaps. The micro-gaps are ranging from 3{mu}m to 30{mu}m with three microchannels parallel to each other to mimic the blood vessel bio-microenvironment. Flow conditions in the device can be controlled to have an environment as similar to that in vivo as possible. We used osteoblast cells with approximate size of 30 {mu}m as a model cell to study the deformation ability of this cell to migrate through the 3 {mu}m gap. Such a device enabled us, for the first time to measure the cell deformation with ease. More importantly, we are able to observe the cellular responses to gaps present in the device and understand the mechanics behind the morphological change of the cells.

Full Text Available Roma multi-problem families in the Netherlands: what hinders their integration?The European Commission has entrusted the EU Member States with the preparation of a national Roma integration strategy in order to address more effectively the challenges of the inclusion of Europe’s largest ethnic minority. This article offers insight into the complex situation of Roma communities in the Netherlands on the basis of the following question: What is known about the problems that occur in families with a Roma background and what recommendations can be made to promote their integration? This article is based on 33 interviews with professionals from different welfare organizations and social services. What follows is that intervention is necessary in certain families, but to accomplish this, problems relating to the attitudes of these families and inconsistencies in care and (law enforcement policies must be overcome. Given the highly complex nature of these issues, the integration of Roma multi problem families requires a long-term and, most of all, consistent approach.Multi-probleemgezinnen met een Roma-achtergrond: waarom verloopt hun integratie moeizaam?De Europese Commissie heeft de EU-lidstaten opgedragen een aanpak te ontwikkelen voor de integratie van Roma, zijnde de grootste etnische minderheidsgroep in Europa. Deze bijdrage belicht de situatie in Nederland aan de hand van de volgende vraag: Wat is onder professionals bekend over de problemen die zich bij gezinnen met een Roma-achtergrond voordoen en welke aanbevelingen kunnen worden gedaan om hun integratie te bevorderen? Wat volgt is dat interventie in bepaalde gezinnen noodzakelijk is, maar dat de aanpak stuit op de houding en leefwijze van deze gezinnen en op inconsistenties in de hulpverlening en handhaving. Wat nodig is, is aandacht voor het bijzondere van de problematiek zonder deze te verbijzonderen, en versterking van de ketenregie.

In the summer, energy use in most types of cultivation depends mostly on the CO2 need, which is determined by the desired CO2 concentration in the greenhouse and the window opening. Based on the results of a literature study, knowledge of crop experts and model calculations with altered and standard cultivation strategy the aim is to demonstrate that CO2 and energy can be deployed more efficiently. Chapter 2 briefly discusses the working method and lists the cases for cucumber. Next, Chapter 3 discusses in more detail the extent to which environment factors such as light, CO2 and temperature influence photosynthesis and plant growth and how this has been processed in growth models. Chapter 4 shows the results in the area of production, energy saving and business economics for seven cases. In addition several reactions of growers are included. Chapter 5, finally, addresses several points for discussion and provides conclusions and recommendations. (mk) [Dutch] Gedurende de zomermaanden is het energieverbruik in de meeste teelten vooral afhankelijk van de CO2 behoefte, bepaald door de gewenste CO2 concentratie in de kas en de raamopening.

The conversion of a fossil fuel-based economy into a bio-based economy will probably be restricted in the European Union (EU) by the limited supply of ecologically sustainable biomass. It appears realistic that, for the EU, the sustainable biomass supply will be enough to meet about 10% of the final energy and feedstock consumption in 2030. Under optimistic assumptions, this supply might increase to 20%. EU Member States, in their Renewable Energy Action Plans for 2020, already aim to apply an amount of biomass that already approaches this 10%. Therefore, from a sustainability perspective, there is an urgent need to guarantee ecologically sustainable biomass production. In considering sustainable biomass production, land use is the most critical issue, especially the indirect land-use impacts on greenhouse gas emissions and biodiversity. The use of waste resources and agricultural and forestry residues, that does not involve additional land use, therefore, would be a sustainable option. Technically, it is possible to use these types of resources for most applications in a bio-based economy. However, it seems unlikely that, by 2030, waste and residue resources will contribute more than three to four per cent to the final energy and feedstock consumption in Europe. Moreover, many waste and residue resources currently already have useful applications; for instance, as feed or soil improvers. These are the main findings of a quick-scan analysis carried out by the PBL Netherlands Environmental Assessment Agency and CE Delft on the sustainability of a bio-based economy. Three priorities can be distinguished in the transition to an ecologically sustainable bio-based economy that aims to reduce the consumption of fossil fuels: (1) develop new technologies, procedures and infrastructure to collect or to produce more biomass without using directly or indirectly valuable natural land; (2) develop technologies to produce hydrocarbons from types of biomass that have potentially

Social Life Cycle Approach as a Tool for Promoting the Market Uptake of Bio-Based Products from a Consumer Perspective

Directory of Open Access Journals (Sweden)

Pasquale Marcello Falcone

2018-03-01

Full Text Available The sustainability of bio-based products, especially when compared with fossil based products, must be assured. The life cycle approach has proven to be a promising way to analyze the social, economic and environmental impacts of bio-based products along the whole value chain. Until now, however, the social aspects have been under-investigated in comparison to environmental and economic aspects. In this context, the present paper aims to identify the main social impact categories and indicators that should be included in a social sustainability assessment of bio-based products, with a focus on the consumers’ category. To identify which social categories and indicators are most relevant, we carry out a literature review on existing social life cycle studies; this is followed by a focus group with industrial experts and academics. Afterwards, we conduct semi-structured interviews with some consumer representatives to understand which social indicators pertaining to consumers are perceived as relevant. Our findings highlight the necessity for the development and dissemination of improved frameworks capable of exploiting the consumers’ role in the ongoing process of market uptake of bio-based products. More specifically, this need regards the effective inclusion of some social indicators (i.e., end users’ health and safety, feedback mechanisms, transparency, and end-of-life responsibility in the social life cycle assessment scheme for bio-based products. This would allow consumers, where properly communicated, to make more informed and aware purchasing choices, therefore having a flywheel effect on the market diffusion of a bio-based product.

Photobiology of Symbiodinium revisited: bio-physical and bio-optical signatures

Light is often the most abundant resource within the nutrient-poor waters surrounding coral reefs. Consequently, zooxanthellae ( Symbiodinium spp.) must continually photoacclimate to optimise productivity and ensure coral success. In situ coral photobiology is becoming dominated by routine assessments using state-of-the-art non-invasive bio-optical or chlorophyll a fluorescence (bio-physical) techniques. Multiple genetic types of Symbiodinium are now known to exist; however, little focus has been given as to how these types differ in terms of characteristics that are observable using these techniques. Therefore, this investigation aimed to revisit and expand upon a pivotal study by Iglesias-Prieto and Trench (1994) by comparing the photoacclimation characteristics of different Symbiodinium types based on their bio-physical (chlorophyll a fluorescence, reaction centre counts) and bio-optical (optical absorption, pigment concentrations) ‘signatures’. Signatures described here are unique to Symbiodinium type and describe phenotypic responses to set conditions, and hence are not suitable to describe taxonomic structure of in hospite Symbiodinium communities. In this study, eight Symbiodinium types from clades and sub-clades (A-B, F) were grown under two PFDs (Photon Flux Density) and examined. The photoacclimation response by Symbiodinium was highly variable between algal types for all bio-physical and for many bio-optical measurements; however, a general preference to modifying reaction centre content over effective antennae-absorption was observed. Certain bio-optically derived patterns, such as light absorption, were independent of algal type and, when considered per photosystem, were matched by reaction centre stoichiometry. Only by better understanding genotypic and phenotypic variability between Symbiodinium types can future studies account for the relative taxonomic and physiological contribution by Symbiodinium to coral acclimation.

The conversion of biomass in an energy combine based on primary gasification yields a gas that can be used as fuels gas, for synthesis of motor fuels (methanol or other) or for electric power production. The study gives examples of alternative product mixes. The conclusions of the study are: (1) Potential of new, not yet utilised biomass is available, and new areas of applications, where oil is presently used, are needed to develop the potential. Motor fuel production (methanol, DME) is a presumption in the BioMeeT-study. (2) Yield figures in the energy combine are comparable to those of now used bio-systems for power and co-generation. (3) Which one of the cases in the BioMeeT-project is the most favourable cannot be decided on a plant-to-plant basis alone but the entire system for supply energy carriers in the region has to be considered, as the all plants within the system may change. This would require further investigations. Moreover, the results will be different in various regions in Sweden and Europe due to the markets for all energy carriers. (4) At today's conditions in the Trollhaettan region it must be stated that there is only room for dedicated bio-methanol/DME production (provided such a market will come) with moderate addition to the district heating system as in the BAL-project. (5) In the longer term the future supply of all energy carriers, including new electric power and new bio-fuels, has to be considered for new plants and at renewals. In such a case an energy combine as in the BioMeeT-project may be a central conversion plant with gas deliveries to satellites such as local co-generation, district heat and industries in a regional system within a 50 - 100 km radius. This should be included in regional planning for the future.

In the present work, silica based bio-hybrid composite has been prepared using Streptococcus lactis cells and silica nanoparticles through one step single process of spray drying. Bio-hybrids have many desired characteristics, and are thus used in a wide range of applications for example environmental cleanup which is of increasing importance. Thermogravimetric and thermodynamic analysis have been employed to understand the binding of uranium to the synthesized bio-hybrid material. Analysis of the thermodynamic parameters (ΔG 0 , ΔS 0 and ΔH 0 ) provides information regarding the inherent energy and feasibility of the sorption process. (author)

The bio-environment has been the single most important correlation in human history and can successfully promote international co-operational co-operation and understanding. With the construction of a network for collaboration, the 'Danube Countries' can come together in celebration of their culture and heritage. As the Danube flows from the Black Forest to the Black Sea, it carries messages of peace, hope and co-operation. Applying these messages to every endeavour can improve our quality of life and lead to a brighter future. Since its inception in 1985, the Bio politics International Organization (B.I.O.) has been labouring to raise awareness of the urgent need to instate a new system of norms and principles, compatible with sound environmental management and with the most important task of ensuring global literacy on environmental issues. Along with critically re-assessing the concept of profit, the goal is to adopt a system of bio centric values, where respect for the bio-environment will govern our every action and thought

Highlights: • Coffee grounds wastes were successfully liquefied yielding a bio-based polyol. • Coffee grounds derived foams formulations were optimized by tuning reagents’ contents. • The viscoelastic properties of these foams are promising to expand their applications. - Abstract: In this work the preparation of viscoelastic bio-based polyurethane foams (PUFs) using polyols obtained via acid liquefaction of coffee grounds wastes has been optimized. In a first stage, the effect of different ratios of isocyanate content to hydroxyl number (0.6, 0.7 and 0.8) and of three distinct percentages of catalyst (3%, 5% and 7%) on the extent of the polymerization reaction was studied by infrared spectroscopy. Next, different percentages of surfactant (14%, 16% and 18%) and blowing agent (12%, 14% and 16%) were used to assess their effect on the density, thermal conductivity and mechanical properties of the foams, including their recovery time. The mechanical properties of the ensuing foams proved to be very interesting due to their viscoelastic behavior. PUFs were also characterized by scanning electron microscopy (SEM) revealing a typical cellular structure and by thermogravimetric analysis (TGA) which proved that these materials are thermally stable up to 190 °C. These results suggest other potential applications for these materials beyond heat insulation in areas where damping properties can be an added value

Bio-oil can be upgraded through hydrodeoxygenation (HDO). Low-cost and effective catalysts are crucial for the HDO process. In this study, four inexpensive combinations of Ni based activated carbon synergistic catalysts including Ni/AC, Ni-Fe/AC, Ni-Mo/AC and Ni-Cu/AC were evaluated for HDO of prairie cordgrass (PCG) bio-oil. The tests were carried out in the autoclave under mild operating conditions with 500psig of H2 pressure and 350°C temperature. The catalysts were characterized by X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) and transmission electron microscope (TEM). The results show that all synergistic catalysts had significant improvements on the physicochemical properties (water content, pH, oxygen content, higher heating value and chemical compositions) of the upgraded PCG bio-oil. The higher heating value of the upgraded bio-oil (ranging from 29.65MJ/kg to 31.61MJ/kg) improved significantly in comparison with the raw bio-oil (11.33MJ/kg), while the oxygen content reduced to only 21.70-25.88% from 68.81% of the raw bio-oil. Compared to raw bio-oil (8.78% hydrocarbons and no alkyl-phenols), the Ni/AC catalysts produced the highest content of gasoline range hydrocarbons (C6-C12) at 32.63% in the upgraded bio-oil, while Ni-Mo/AC generated the upgraded bio-oil with the highest content of gasoline blending alkyl-phenols at 38.41%.

Bio-diesel based on rape seed (RME, Rape Methyl Esther), often referred to as first generation bio-diesel, is a renewable fuel with CO{sub 2} reduction potential. Mixed with conventional diesel it can be used directly in existing diesel engines. The EU target for the use of bio-fuels in the transport sector was 2 % by 2005 and is 5.75 % by 2010. In Denmark, the use of bio-fuels in the transport sector is not viewed as a cost-effective CO{sub 2} reduction measure. This conclusion concerning the cost-effectiveness of bio-fuels was partly based on calculations of the CO2 reduction cost for Danish-produced RME made by the Danish Energy Authority in 2003. At that time the cost was estimated at 360 DKK/tonne CO{sub 2}. Since then some of the assumptions behind the calculations have changed. The overall objective of this report is to update the Danish Energy Authority's study from 2003, taking into account revised assumptions. The report also attempts to examine the uncertainties associated with the calculations by including extended sensitivity analyses. The report draws the following conclusions: 1) The CO{sub 2} reduction cost for Danish produced RME is estimated at 860 DKK/tonne CO{sub 2}, which is significantly higher than the result obtained by the Danish Energy Authority in 2003. 2) The difference from the Danish Energy Authority's original calculations is principally due to a higher rape seed price based on the market price on rape seed. 3) The uncertainty in both estimates is substantial, and there is about 15 % probability of the reduction costs being lower than the target of 180 DKK/tonne CO2 set by the government.

Bio-electrospraying (BES) has demonstrated great promise as a rapidly evolving strategy for tissue engineering and regenerative biology/medicine. Since its discovery in 2005, many studies have confirmed that cells (immortalized, primary and stem cells) and whole organisms (Danio rerio, Xenopus tropicalis, Caenorhabditis elegans to Drosophila) remain viable post-bio-electrospraying. Although this bio-protocol has achieved much, it suffers from one crucial problem, namely the ability to precisely control the number of cells within droplets and or encapsulations. If overcome, BES has the potential to become a high-efficiency biotechnique for controlled cell encapsulation, a technique most useful for a wide range of applications in biology and medicine ranging from the forming of three-dimensional cultures to an approach for treating diseases such as type I diabetes. In this communication, we address this issue by demonstrating the coupling of BES with droplet-based microfluidics for controlling live cell numbers within droplets and residues. (communication)

As a novel kind of polymer with covalently linked core-shell structure, star polymers behave in nanostructure in aqueous medium at all concentration range, as unimolecular micelles at high dilution condition and multi-micelle aggregates in other situations. The unique morphologies endow star polymers with excellent stability and functions, making them a promising platform for bio-application. A variety of functions including imaging and therapeutics can be achieved through rational structure design of star polymers, and the existence of plentiful end-groups on shell offers the opportunity for further modification. In the last decades, star polymers have become an attracting platform on fabrication of novel nano-systems for bio-imaging and diagnosis. Focusing on the specific topology and physicochemical properties of star polymers, we have reviewed recent development of star polymer-based unimolecular micelles and their bio-application in imaging and diagnosis. The main content of this review summarizes the synthesis of integrated architecture of star polymers and their self-assembly behavior in aqueous medium, focusing especially on the recent advances on their bio-imaging application and diagnosis use. Finally, we conclude with remarks and give some outlooks for further exploration in this field. Copyright © 2018 Elsevier Ltd. All rights reserved.

Diamond bio electronics.

The use of diamond for advanced applications has been the dream of mankind for centuries. Until recently this dream has been realized only in the use of diamond for gemstones and abrasive applications where tons of diamonds are used on an annual basis. Diamond is the material system of choice for many applications, but its use has historically been limited due to the small size, high cost, and inconsistent (and typically poor) quality of available diamond materials until recently. The recent development of high quality, single crystal diamond crystal growth via the Chemical Vapor Deposition (CVD) process has allowed physcists and increasingly scientists in the life science area to think beyond these limitations and envision how diamond may be used in advanced applications ranging from quantum computing, to power generation and molecular imaging, and eventually even diamond nano-bots. Because of diamond's unique properties as a bio-compatible material, better understanding of diamond's quantum effects and a convergence of mass production, semiconductor-like fabrication process, diamond now promises a unique and powerful key to the realization of the bio-electronic devices being envisioned for the new era of medical science. The combination of robust in-the-body diamond based sensors, coupled with smart bio-functionalized diamond devices may lead to diamond being the platform of choice for bio-electronics. This generation of diamond based bio-electronic devices would contribute substantially to ushering in a paradigm shift for medical science, leading to vastly improved patient diagnosis, decrease of drug development costs and risks, and improved effectiveness of drug delivery and gene therapy programs through better timed and more customized solutions.

when we factor in the renewable energy subsidy (SDE+) and investment subsidies such as MEI and EIA. Assuming the cheaper 800 kWe installations, the SDE+ subsidy of euro 90/MWh, current wood chipping prices and co-burning of cheaper residual waste such as reed, the payback time is 3 to 4 years. If the biomass can be contracted for 4 to 5 years at a fixed price, then an investment in a CHP gasifier is definitely an interesting alternative to the current gas CHP installations within the horticulture sector. This feasibility study assumes that the horticulturer's biomass costs are euro 35/tonne for a wood and reed mixture (87.5% and 12.5% respectively) and euro 40/tonne for 100% wood chippings, including transport. This assumes euro 25/tonne reed removal costs for the supplier, the province of Utrecht, Natuurmonumenten and/or the Forestry Commission (Staatsbosbeheer). In this case these parties do not pay euro 35/tonne for the processing of the waste by a green waste collector. The horticulturer receives euro 10/tonne for buying the reed, which offsets part of his investment risk. The cheap reed thus makes a significant contribution to the profitability of the installation. However, there is insufficient reed in the province of Utrecht to meet the total energy requirement of the Zwarts nursery, let alone for more energy projects. Moreover, the placement of the installation is subject to an Area Exploitation (WABO) Permit and the implementation of several measures. The installation is feasible in the current situation, both in terms of placement, technical compatibility and logistics, the supply of biomass and the removal of combustion ash [Dutch] Dit rapport beschrijft de haalbaarheid van een vergasser-WKK-installatie bij Gerberakwekerij Zwarts.

As a rule, oil- and gas-processing equipment and pipelines are attacked by different microorganisms. Their vital ability determines processes of bio-deterioration and bio-corrosion that lead often to technological accidents and severe environmental contamination. Bio-films presenting a complex association of different microorganisms and their metabolites are responsible for most of damages. In this context, to study the role bio-films may play in processes of bio-damages and in efficacy of protective measures is important. We have developed method of culturing bio-films on the surface of metal coupons by using a natural microbial association isolated from oil-processing sites. Simple and informative methods of determining microbiological parameters of bio-films required to study bio-corrosion processes are also developed. In addition, a method of electron microscopic analysis of bio-films and pitting corrosion is offered. Using these methods, we conducted model experiments to determine the dynamics of corrosion processes depending on qualitative and quantitative composition of bio-films, aeration conditions and duration of the experiment. A harmful effect of soil bacteria and micro-mycetes on different pipeline coatings was also investigated. Experiments were conducted within 3-6 months and revealed degrading action of microorganisms. This was confirmed by axial tension testing of coatings. All these approaches will be used for further development of measures to protect gas- and oil-processing equipment and pipelines against bio-corrosion and bio-damages (first of all biocides).

The intention behind this paper is to explore the potential of extracting bio based products such as lactic acid and further organic acid compounds during a successful composting process, by inserting an additional pre-treatment level into the existing process. The fundamental idea of extracting bio based products and biogas is based on the extension of a composting plant with an anaerobic intermediate level of maceration and a bypass reactor as a potential bio-refinery. For the extraction of carboxylic acid out of the macerated substance the principle of electrodialysis on a laboratory scale can be successfully verified by means of concentration of free acids. The concluding assessment of the composting plant Darmstadt-Kranichstein with regards to its potential shows that further examination on a large scale for the extraction of biobased products using biowaste is deemed to be appropriate on material and energetic consideration. The study demonstrates the potential for a combined aerobic/anaerobic plant with composting, renewable energy and secondary raw materials generation. (orig.)

This paper provides an overview on investigations for a new technology to generate bio-based fuel additives from bio-waste. The investigations are taking place at the composting plant in Darmstadt-Kranichstein (Germany). The aim is to explore the potential of bio-waste as feedstock in producing different bio-based products (or bio-based fuels). For this investigation, a facultative anaerobic process is to be integrated into the normal aerobic waste treatment process for composting. The bio-waste is to be treated in four steps to produce biofuels. The first step is the facultative anaerobic treatment of the waste in a rotting box namely percolate to generate a fatty-acid rich liquid fraction. The Hydrolysis takes place in the rotting box during the waste treatment. The organic compounds are then dissolved and transferred into the waste liquid phase. Browne et al. (2013) describes the hydrolysis as an enzymatically degradation of high solid substrates to soluble products which are further degraded to volatile fatty acids (VFA). This is confirmed by analytical tests done on the liquid fraction. After the percolation, volatile and medium chain fatty acids are found in the liquid phase. Concentrations of fatty acids between 8.0 and 31.5 were detected depending on the nature of the input material. In the second step, a fermentation process will be initiated to produce additional fatty acids. Existing microorganism mass is activated to degrade the organic components that are still remaining in the percolate. After fermentation the quantity of fatty acids in four investigated reactors increased 3-5 times. While fermentation mainly non-polar fatty acids (pentanoic to octanoic acid) are build. Next to the fermentation process, a chain-elongation step is arranged by adding ethanol to the fatty acid rich percolate. While these investigations a chain-elongation of mainly fatty acids with pair numbers of carbon atoms (acetate, butanoic and hexanoic acid) are demonstrated. After

In recent years, bio-based chemicals have gained interest as a renewable alternative to petrochemicals. However, there is a significant need to assess the technological, biological, economic and environmental feasibility of bio-based chemicals, particularly during the early research phase. Recently, the Multi-scale framework for Sustainable Industrial Chemicals (MuSIC) was introduced to address this issue by integrating modelling approaches at different scales ranging from cellular to ecological scales. This framework can be further extended by incorporating modelling of the petrochemical value chain and the de novo prediction of metabolic pathways connecting existing host metabolism to desirable chemical products. This multi-scale, multi-disciplinary framework for quantitative assessment of bio-based chemicals will play a vital role in supporting engineering, strategy and policy decisions as we progress towards a sustainable chemical industry. © 2015 Authors; published by Portland Press Limited.

In order to reduce dependency on foreign oil, there is a growing need to develop and commercialize new bio-based green materials and technologies that can produce bio-based structural materials that are competitive with current synthetic products. The use of bio-based products would also improve the environment and create new opportunities for the agricultural economy. This paper described ongoing research into bio-based materials and products that replace petroleum-based products. In particular, it examined the use of biocomposites made by embedding natural/biofibers such as kenaf, hemp, flax, jute, henequen, pineapple leaf fiber, corn stalk fibers and native Michigan grasses into petroleum-derived traditional plastics such as polypropylene, unsaturated polyesters and epoxies. It also examines the use of green biocomposites developed by embedding these bio-fibers into renewable resource-based bioplastics such as cellulosic plastics and soy-based plastics. New processing methods that combine biofibers with plastics were needed to produce the biocomposites with desirable mechanical properties. The study showed that biofiber reinforced petroleum-based plastic biocomposites can produce a structural material that offers a balance between ecology, economy and technology. The potential for using these materials for automotive and building materials was also presented. 1 tab., 28 figs.

Bio-composite aerogels based on bleached cellulose fibers (BCF) and cellulose nanoparticles having various morphological and physico-chemical characteristics are prepared by a freeze-drying technique and characterized. The various composite aerogels obtained were compared to a BCF aerogel used as the reference. Severe changes in the material morphology were observed by SEM and AFM due to a variation of the cellulose nanoparticle properties such as the aspect ratio, the crystalline index and the surface charge density. BCF fibers form a 3D network and they are surrounded by the cellulose nanoparticle thin films inducing a significant reduction of the size of the pores in comparison with a neat BCF based aerogel. BET analyses confirm the appearance of a new organization structure with pores of nanometric sizes. As a consequence, a decrease of the thermal conductivities is observed from 28mWm(-1)K(-1) (BCF aerogel) to 23mWm(-1)K(-1) (bio-composite aerogel), which is below the air conductivity (25mWm(-1)K(-1)). This improvement of the insulation properties for composite materials is more pronounced for aerogels based on cellulose nanoparticles having a low crystalline index and high surface charge (NFC-2h). The significant improvement of their insulation properties allows the bio-composite aerogels to enter the super-insulating materials family. The characteristics of cellulose nanoparticles also influence the mechanical properties of the bio-composite aerogels. A significant improvement of the mechanical properties under compression is obtained by self-organization, yielding a multi-scale architecture of the cellulose nanoparticles in the bio-composite aerogels. In this case, the mechanical property is more dependent on the morphology of the composite aerogel rather than the intrinsic characteristics of the cellulose nanoparticles.

This work constitutes a preliminary study in which the capacity of non-Saccharomyces yeasts isolated from ancient distilleries as bio-control agents against moulds and in the treatment of waste waters contaminated by heavy metals-i.e. bio-remediation-is shown. In the first control assays, antagonist effect between non-Saccharomyces yeasts, their extracts and supernatants against some moulds, analysing the plausible (not exhaustive) involved factors were qualitatively verified. In addition, two enzymatic degrading properties of cell wall plant polymers, quitinolitic and pectinolitic, were screened. Finally, their use as agents of bio-remediation of three heavy metals (cadmium, chromium and lead) was analysed semi-quantitatively. The results showed that all isolates belonging to Pichia species effectively inhibited all moulds assayed. Moreover, P. kudriavzevii is a good candidate for both bio-control and bio-remediation because it inhibited moulds and accumulated the major proportion of the three tested metals.

Conditions for greening the Dutch economy; Voorwaarden voor de vergroening van de economie in Nederland

Hanemaaijer, A.; Manders, T.; Kruitwagen, S.; Dietz, F.

Greening the economy is considered to be one of the major worldwide challenges of the coming decades. Greening is about limiting the use of natural resources and sparing the environment. By taking into account the limits of the natural capital we can safeguard prosperity in the long term. Greening is important for the Netherlands, too. Using energy, raw materials, land and water more efficiently will make the Dutch economy less vulnerable and the environment cleaner. Focusing on green growth is thus not so much the short-term answer to the present economic crisis but rather a long-term contribution to strengthening the structure of the Dutch economy. This strengthening is not something that will happen of its own accord but requires an active role on the part of the government together with the business sector and the general public. A long-term vision for greening the economy forms an important first step. How to measure progress is another important element in aiming for the goal of green growth. A different set of rules will also be required in order to steer society towards greening. The cost of environmental pollution, for example, should be better reflected in prices. Abolishing subsidies and tax incentives that stand in the way of this greening process is also part of this. Implementing tax proposals of this kind, of course, requires weighing many factors. The government could also create better conditions for the development and application of innovations that spare the environment. This report sets out some of the requirements for greening the Dutch economy and suggests ways in which these could be implemented in some areas. At the same time, the document identifies those areas in need of further investigation to gain a better overview of what 'going for green growth' would mean for the Netherlands and what this requires.

Full Text Available Thermoplastic vulcanizate (TPV combines the high elasticity of elastomers and excellent processability of thermoplastics. Novel bio-based TPV based on poly (lactide (PLA and poly (1,4-butanediol/2,3-butanediol/succinate/itaconic acid (PBBSI were prepared in this research. PBBSI copolyesters were synthesized by melting polycondensation, and the molecular weights, chemical structures and compositions of the copolyesters were characterized by GPC, NMR and FTIR. Bio-based 2,3-butanediol was successfully incorporated to depress the crystallization behavior of the PBBSI copolyester. With an increase of 2,3-butanediol content, the PBBSI copolyester transformed from a rigid plastic to a soft elastomer. Furthermore, the obtained TPV has good elasticity and rheological properties, which means it can be applied as a 3D-printing material.

There is an increasing need for the establishment of a cervical cancer bio-bank that will facilitate both clinical and basic research. The cervical cancer bio-bank was first established in January 1999 and included two stages. First, a GWAS-based sample collection was conducted with special emphasis on the diagnosis and the retrieval of the corresponding bio-specimens, especially blood samples. Second, clinical data and their corresponding bio-specimens were routinely collected and handled. Notably, these bio-specimens also included samples from Wufeng Tujia Autonomous County, which has the highest incidence of cervical cancer in China. The specimens were collected from patients with cervical cancer and those with cervical intraepithelial neoplasia, while the control samples were collected from normal individuals. With special emphasis on clinical data and blood samples for the GWAS analysis, the collection of other bio-specimens was slow, and the pairing of specimens and clinical data was poor during the first stage. However, in the second stage, the pairing of the clinical data and its corresponding bio-specimens improved. At present, the samples procured and preserved in the bio-bank cover most regions of China and different ethnic groups for both the normal controls and cervical cancer patients of different pathological categories. This bio-bank of cervical cancer specimens from the Chinese population will greatly promote the studies of cervical cancer in China.

The introduction of antioxidants in polymers is the main way to prevent or delay the degradation process. In particular natural antioxidants receive attention in the food industry also because of their presumed safety. In this work bio-polymers, i.e. a commercial starch-based polymer (Mater-Bi®) and a bio-polyester (PLA), and a bio-polyether (PEO) were additivated with quercetin, a natural flavonoid antioxidants, in order to formulate bio-based films for ecosustainable packaging and outdoor applications. The photo-oxidation behavior of unstabilized and quercetin stabilized films was analyzed and compared with the behavior of films additivated with a commercial synthetic light stabilizer. The quercetin is able to slow down the photo-degradation rate of all bio-polymeric films investigated in similar way to the synthetic stabilizer.

[Dutch] Voor een goedwerkende markt is een goed geinformeerde consument van belang. Uit de Consumentenmonitor, kwalitatief onderzoek dat de NMa in 2006 heeft laten uitvoeren, is gebleken dat de consument bij een overstap vaak gebruik maakt van prijsvergelijkingssites. Het belang van dergelijke sites neemt alleen maar toe. Door een grotere differentiatie aan producten en meer variatie in prijsstelling wordt een goede vergelijking van energieleveranciers voor de gemiddelde consument steeds lastiger. Ook voor de prijsvergelijkingssites neemt de complexiteit toe. De Directie Toezicht Energie (DTe) van de Nederlandse Mededingingsautoriteit (NMa) onderzoekt sinds 2004 jaarlijks de kwaliteit van (prijs)vergelijkingssites voor elektriciteit en gas.

A combination between the nanostructured photocatalyst and cellulose-based materials promotes a new functionality of cellulose towards the development of new bio-hybrid materials for various applications especially in water treatment and renewable energy. The excellent compatibility and association between nanostructured photocatalyst and cellulose-based materials was induced by bio-combability and high hydrophilicity of the cellulose components. The electron rich hydroxyl group of celluloses helps to promote superior interaction with photocatalyst. The formation of bio-hybrid nanostructured are attaining huge interest nowadays due to the synergistic properties of individual cellulose-based material and photocatalyst nanoparticles. Therefore, in this review we introduce some cellulose-based material and discusses its compatibility with nanostructured photocatalyst in terms of physical and chemical properties. In addition, we gather information and evidence on the fabrication techniques of cellulose-based hybrid nanostructured photocatalyst and its recent application in the field of water treatment and renewable energy.

Bio-fuels for the gas turbine: A review

Gupta, K.K.; Rehman, A.; Sarviya, R.M.

2010-01-01

Due to depletion of fossil fuel, bio-fuels have generated a significant interest as an alternative fuel for the future. The use of bio-fuels to fuel gas turbine seems a viable solution for the problems of decreasing fossil-fuel reserves and environmental concerns. Bio-fuels are alternative fuels, made from renewable sources and having environmental benefit. In recent years, the desire for energy independence, foreseen depletion of nonrenewable fuel resources, fluctuating petroleum fuel costs, the necessity of stimulating agriculture based economy, and the reality of climate change have created an interest in the development of bio-fuels. The application of bio-fuels in automobiles and heating applications is increasing day by day. Therefore the use of these fuels in gas turbines would extend this application to aviation field. The impact of costly petroleum-based aviation fuel on the environment is harmful. So the development of alternative fuels in aviation is important and useful. The use of liquid and gaseous fuels from biomass will help to fulfill the Kyoto targets concerning global warming emissions. In addition, to reduce exhaust emission waste gases and syngas, etc., could be used as a potential gas turbine fuel. The term bio-fuel is referred to alternative fuel which is produced from biomass. Such fuels include bio-diesel, bio-ethanol, bio-methanol, pyrolysis oil, biogas, synthetic gas (dimethyl ether), hydrogen, etc. The bio-ethanol and bio-methanol are petrol additive/substitute. Bio-diesel is an environment friendly alternative liquid fuel for the diesel/aviation fuel. The gas turbine develops steady flame during its combustion; this feature gives a flexibility to use alternative fuels. Therefore so the use of different bio-fuels in gas turbine has been investigated by a good number of researchers. The suitability and modifications in the existing systems are also recommended.

Bio-Based Polyols from Seed Oils for Water-Blown Rigid Polyurethane Foam Preparation

Directory of Open Access Journals (Sweden)

Paweena Ekkaphan

2016-01-01

Full Text Available The preparation of water-blown rigid polyurethane (RPUR foams using bio-based polyols from sesame seed oil and pumpkin seed oil has been reported. Polyols synthesis involved two steps, namely, hydroxylation and alcoholysis reaction. FTIR, NMR, and ESI-MS were used to monitor the process of the synthesized polyols and their physicochemical properties were determined. The resulting polyols have OH number in the range of 340–351 mg KOH/g. RPUR foams blown with water were produced from the reaction of biopolyols with commercial polymeric methylene diphenyl diisocyanate (PMDI. The proper PUR formulations can be manipulated to produce the desired material applications. These seed oil-based RPUR foams exhibited relatively high compressive strength (237.7–240.2 kPa with the density in the range of 40–45 kg/m3. Additionally, the cell foam morphology investigated by scanning electron microscope indicated that their cellular structure presented mostly polygonal closed cells. The experimental results demonstrate that these bio-based polyols can be used as an alternative starting material for RPUR production.

Biopolymers have been serving the mankind in various ways since long. Over the last few years, these polymers have found great demand in various domains which includes bio medicine, tissue engineering, bio sensor fabrications etc. because of their excellent bio compatibility. In this context, chitosan has found global attention due to its environmentally benign nature, biocompatibility, biodegradability, and ease of availability. In last one decade or so, extensive research in active biomaterials, like chitosan has led to the development of novel delivery systems for drugs, genes, and biomolecules; and regenerative medicine. Additionally, chitosan has also witnessed its usage in functionalization of biocompatible materials, nanoparticle (NP) synthesis, and immobilization of various bio-recognition elements (BREs) to form active bio-surfaces with great ease. Keeping these aspects in mind, we have written a comprehensive review which aims to acquaint its readers with the exceptional properties of chitosan and its usage in the domain of biomedicine, tissue engineering, and biosensor fabrication. Herein, we have briefly explained various aspects of direct utilization of chitosan and then presented vivid strategies towards formulation of chitosan based nanocomposites for biomedicine, tissue engineering, and biosensing applications.
