Book Synopsis Advances of Basic Science for Second Generation Bioethanol from Sugarcane by : Marcos S. Buckeridge
Download or read book Advances of Basic Science for Second Generation Bioethanol from Sugarcane written by Marcos S. Buckeridge and published by Springer. This book was released on 2017-03-10 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the basic science recently produced in Brazil for the improvement of sugarcane as a bioenergy crop and as a raw material for 2nd generation bioethanol production. It reports achievements that have been advancing the science of cell walls, enzymes, genetics, and sustainability related to sugarcane technologies and give continuity to the research reported in the “Routes to Cellulosic Ethanol”, from Springer. The Introduction (Chapter I) explains how the National Institute of Science and Technology of Bioethanol, founded in 2008 in Brazil, became part of the main international initiatives that started to search for forms to use biomass for bioethanol production in Brazil, US and Europe. Part I reports the advances in plant cell wall composition, structure and architecture, and physical characteristics of sugarcane biomass. These discoveries are opening the way to increased efficiency of pretreatments and hydrolysis, being therefore important information for 2nd generation processes as well as for biorefinery initiatives. Part II focuses on the discovery and characterization of hydrolases from microorganisms that could be used in industrial processes. Recent advances in the search for hydrolases using metagenomics is reported. A great number of genes and enzymes from microorganisms have been discovered, affording improvement of enzyme cocktails better adapted to sugarcane biomass. Part III reports two key issues in the process of 2G ethanol, pentose fermentation and sugarcane genetics. These are the discoveries of new yeast species capable of producing ethanol more efficiently from xylose and the advances made on the sugarcane genetics, a key issue to design varieties adapted to 2G ethanol production. Part IV approaches sustainability through two chapters, one discussing the sustainability of the sugarcane agricultural and environmental system and another discussing how national and mainly international policies of Brazil regarding 2G ethanol production affected the country’s strategies to establish itself as an international player in renewable energy area.

Book Synopsis Future Perspectives of 2nd Generation Biofuels by : Rainer Zah
Download or read book Future Perspectives of 2nd Generation Biofuels written by Rainer Zah and published by vdf Hochschulverlag AG. This book was released on 2010 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fossil independence and substantial reductions in CO2 emissions seem to be possible with 2nd generation biofuels. New technologies allow a full carbon-to-fuel conversion of non-edible plant parts such as straw or wood, and the cultivation of algae or salt-resistant plants uncouples bioenergy from food production. Nevertheless, impacts on biodiversity, global land and water use are widely unclear and their competitiveness with 1st generation biofuels and electric mobility is an open question. An interdisciplinary team of Empa, University of Zurich and the Institute of Climate, Environment and Energy in Wuppertal evaluated the most sustainable production techniques and assessed their potential for our future mobility.

This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cependant, avant de mettre en place une infrastructure pour la production de tels biocarburants de seconde génération, il faut se pencher sur les problèmes de logistique de chaîne d'approvisionnement entourant la récolte, le transport et le stockage de la biomasse devant servir de matière première. [...] Une comparaison rapportée en matières sèches nous apprend qu'il est beaucoup plus coûteux de stocker et de transporter de la paille de maïs que de stocker et de transporter en ballots les autres options de matières premières. [...] Le total des coûts associés à la récolte, au stockage et au transport de paille de maïs dans l'est du Canada est supérieur aux coûts logistiques de l'utilisation de paille de céréales dans l'Ouest. [...] Au-delà des économies d'échelle réalisées à l'usine, les chaînes d'approvisionnement établies pour les usines de biocarburant de seconde génération permettent de réaliser certains des avantages économiques résultant de l'utilisation optimale (contrairement à l'utilisation classique) de l'équipement de la chaîne d'approvisionnement. [...] Grâce au volume important et constant de matières premières requis par les usines de biocarburant, il est possible de maximiser l'utilisation annuelle des presses à fourrage, des dispositifs de collecte et des camions, ce qui en retour permet d'étaler le coût en capital de ces équipements sur davantage d'heures de travail et de tonnes de produit.

Book Synopsis Biocarburants : 5 Questions qui dérangent by : Jean-Louis Lemarchand
Download or read book Biocarburants : 5 Questions qui dérangent written by Jean-Louis Lemarchand and published by Editions TECHNIP. This book was released on 2008 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: " Tsunami silencieux ", " insécurité alimentaire grandissante "... Les mots ne manquent pas pour décrire le désastre humanitaire que nous sommes en train de vivre. Devant la multiplication croissante des émeutes de la faim, le monde s'inquiète et les organisations internationales tirent la sonnette d'alarme : cette crise pourrait avoir des conséquences aussi graves qu'une guerre... D'abord présenté comme l'arme suprême contre les émissions de gaz à effet de serre, le biocarburant est aujourd'hui tenu responsable de tous les maux de la terre : flambée du cours des matières premières agricoles, déforestation, crise alimentaire... Considéré il y a peu comme un complément rêvé et " propre " du pétrole pour les transports, le biocarburant aurait même des conséquences dangereuses sur l'environnement. ne serait-il alors qu'une énorme arnaque technique, environnementale et humaine ? faut-il alors abandonner sans tarder l'agrocarburant - appelé ainsi par les écologistes purs et durs - pour protéger la planète et faire reculer la famine à nouveau menaçante ? Ou dont-on attendre que les biocarburants de la deuxième génération, produits de base de denrées non-alimentaires et de déchets des cultures soient efficaces ? A l'heure où le débat fait rage, " Les Biocarburants : cinq questions qui dérangent " est un ouvrage qui nous concerne tous. Il réfléchit sur un sujet majeur de ce début du XXIe siècle qui touche à trois domaines-clés inséparables : l'énergie, l'agriculture et l'environnement.

Book Synopsis The Impacts of Biofuels on the Economy, Environment, and Poverty by : Govinda R. Timilsina
Download or read book The Impacts of Biofuels on the Economy, Environment, and Poverty written by Govinda R. Timilsina and published by Springer. This book was released on 2014-05-20 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in biofuels began with oil shocks in the 1970’s, but the more rapid development and consumption of biofuel industry in recent years has been primarily driven by mandates, subsidies, climate change concerns, emissions targets and energy security. From 2004 to 2006, fuel ethanol grew by 26% and biodiesel grew by 172%. As biofuel production continues to expand, investments in capacity expansion and research and development have been made. The 2008 food crisis emphasized the need to re-examine biofuel consequences. Biofuels remain an important renewable energy resource to substitute for fossil fuels, particularly in the transportation sector, yet biofuels’ success is still uncertain. The future of biofuels in the energy supply mix relies on mitigating potential and improving the environmental gains. This book brings together leading authorities on biofuel from the World Bank to examine all of the impacts of biofuel (economic, social, environmental) within a unified framework and in a global perspective, making it of interest to academics in agricultural and environmental economics as well as industry and policy-makers.

Available in PDF, EPUB and Kindle. Book excerpt: Life-Cycle Assessment of Biorefineries, the sixth and last book in the series on biomass-biorefineries discusses the unprecedented growth and development in the emerging concept of a global bio-based economy in which biomass-based biorefineries have attained center stage for the production of fuels and chemicals. It is envisaged that by 2020 a majority of chemicals currently being produced through a chemical route will be produced via a bio-based route. Agro-industrial residues, municipal solid wastes, and forestry wastes have been considered as the most significant feedstocks for such bio-refineries. However, for the techno-economic success of such biorefineries, it is of prime and utmost importance to understand their lifecycle assessment for various aspects. Provides state-of-art information on the basics and fundamental principles of LCA for biorefineries Contains key features for the education and understanding of integrated biorefineries Presents models that are used to cope with land-use changes and their effects on biorefineries Includes relevant case studies that illustrate main points

Download or read book Les biocarburants written by Daniel Ballerini and published by Editions TECHNIP. This book was released on 2011 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'évolution du contexte énergétique mondial, la prise de conscience des enjeux environnementaux et le développement des actions de recherche sur la production de biocarburants de deuxième et troisième générations ont rendu indispensable la rédaction d'un nouvel ouvrage, qui actualise et enrichit Les Biocarburants - Etat des lieux, perspectives et enjeux du développement paru en 2006, sur tous les aspects techniques, économiques et environnementaux. Cet ouvrage présente l'état de l'art détaillé des filières de production de biocarburants de première génération. Il décrit les nouvelles voies, dites de deuxième génération, qui utilisent la biomasse lignocellulosique comme matière première et commencent à déboucher sur des réalisations industrielles, allant ainsi dans le sens de la réduction de la concurrence entre la ressource alimentaire et l'usage de matières agricoles à des fins énergétiques. Un point technique est également dressé sur la valorisation énergétique des algues (troisième génération) et la production de méthane et d'hydrogène par voies biochimiques. Ce livre arrive à point nommé pour réaffirmer l'intérêt des biocarburants, y compris pour le transport aérien, et éclairer les axes de recherche et de développement technologique dont ils font actuellement l'objet. Il intéressera les industriels du transport, les raffineurs, les forestiers, l'univers agricole et l'industrie agro-alimentaire, mais également les pouvoirs publics, les étudiants, professeurs et chercheurs du monde universitaire.
