Biogas är bästa biobränslet - Ny Teknik

Etanol används även som motorbränsle, då kallad E85 . At the midpoint level, comparison of different LCIA methods showed that ethanol presents lower impacts than gasoline in important categories such as global warming, fossil depletion, and ozone layer depletion. However, ethanol presents higher impacts in acidification, eutrophication, photochemical oxidation, and agricultural land use categories. ethanol has been extensively investigated in life cycle assess- ment (LCA) studies, mainly from a transport bio-fuel perspec- tive (Fu et al.

Med inflöden och utflöden avses the use of a small-scale rapeseed oil, RME and ethanol fuel production system reduced the environmental load in comparison to a medium- and a large-scale system. To fulfil this purpose, a limited LCA, including air-emissions and energy requirements, was carried out for the three fuels and the three plant sizes. Production of ethanol from lignocellulosic materials is a very complex process, which consists of various interdependent steps, such as pretreatment of the raw material, enzymatic hydrolysis of the polysaccharides into sugar monomers, fermentation of the sugars to ethanol, and purification of ethanol.

Enhancing the data basis for LCA through process simulation: The case of lignocellulosic ethanol production in Sweden Conference poster, 2011 One of the application areas of LCA is to assess the environmental impact of emerging technologies in order to support strategies and policies for technological development. A Life-Cycle Analysis of the Greenhouse Gas Emissions from Corn-Based Ethanol ICF prepared this final project report under USDA Contract No. AG-3142-D- 17-0161 in support of the project: Technical Support Communicating Results of “Retrospective and Current Examination of the Lifecycle GHG Emissions of Corn-Based Ethanol” Report. LCA could systematically account for the energy use and emissions at every stage of a product Key issues in ethanol LCA –Agriculture and conversion technology advancements –Land-use change –Co-product allocation methodology ANL continues monitoring the technology advancement in biofuel industry and implement is to use life cycle assessment (LCA) to evaluate the global warming potential (GWP), water use, and net energy value (NEV) associated with the EISA-mandated 16 bgy cellulosic biofuels target, which is assumed in this study to be met by cellulosic-based ethanol, and the EISA-mandated 15 bgy conventional corn ethanol target. inkluderas är etanol från vete, sockerbetor och sockerrör (import från Brasilien), RME från raps, biogas från sockerbetor, vall, majs samt från restprodukter i form av hushållsavfall, industriavfall och gödsel.

Results for cellulose, ethanols, lignosulfonates, vanillin, sodium hypochlorite, sodium hydroxide and hydrochloric acid. Authors: Ingunn Saur Modahl and Ellen Soldal Project no: 1721 Project title: LCA av Borregaard sine produkt Se hela listan på naturvardsverket.se This LCA study was designed to directly compare the conversion of corn stover into ethanol, isobutanol, and n‐butanol for vehicle use. Therefore, only neat biofuels were evaluated, eliminating any gasoline or denaturant blending. Ethanol currently is produced commercially from starch sources such as corn grain and blended into gasoline.
