Ethanol and biodiesel produced from straw and forest residues in emerging biorefinery systems were found to have a lower climate impact and better energy balance than fossil fuels. Numerous efforts have been made to evaluate the life cycle of lignocellulosic ethanol with LCA methodologies and deals with feedstock, energy paths, conversion technologies, allocation methods Projektuppgift – Livscykelanalys (LCA) Syfte Etanol (E85) eller diesel Grupp 4) Drivmedel för personbil, biogas eller hybrid (bensin + el) 2012-12-13 · The treatment of distillers' grains and solubles (DGS), a valuable co-product from corn ethanol plants, in the life-cycle analysis (LCA) of corn ethanol is important because it can affect results regarding corn ethanol's GHG emissions (Wang et al 2011b). 2017-02-23 · Some LCA studies have taken steps towards investigating the potential environmental benefits of co-locating and partly integrating enzyme production with ethanol conversion [10–12], but the full potential of an integrated process approach, using part of the lignocellulosic feedstock for enzyme production, has only recently been addressed [37, 38]. 4 Cheyenne Harden – CEE 598 – LCA of Switchgrass Ethanol for AZ Since some switchgrass cultivars are native to the state of Arizona, this study attempts to consider the impacts from producing switchgrass locally in order to produce ethanol for a state policy on alternative energy. 2021-03-01 · Budsberg et al.

2 Apr 2019 The study also states that when ethanol is refined at natural gas-powered refineries, the greenhouse gas emissions are even lower, around 43

This number has been the criticism of corn ethanol because of the large amount of fossil energy used to produce ethanol. a) Ethanol b) Incremental oil produced via CO 2 enhanced oil recovery (EOR) c) Power production from coal-fired or natural gas power plants • How does (c) compare to alternative sources of electric power generation?

jöanalyser. Den svarar på frågor som "är det bra att tillverka etanol från korn för att tillverka bränsle", istället för "hur förändras miljön lokalt om vi bygger en etanolfabrik i Järfälla"? Utveckling av LCA inom bygg- och fastighetsbranschen Intresset för miljöbedömningar med hjälp av livscykelanalys, LCA, ökar.

The 2015 LCA of products from the wood-based biorefinery at Borregaard, Sarpsborg. 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. According to the Congressional Budget Office, 10.8 billion gallons of corn ethanol were produced in 2009 [2].

The SimaPro 8 LCA software tool, with its Eco-invent commercial life cycle inventory database, as well as the Argonne National Laboratory GREET model, were used for the LCA data. Sensitivity and uncertainty analyses included comparison of ethanol types in the Eco-invent database. Ethanol via fermentation from Corn Sugarcane Sorghum (grain, juice, cane) Cellulosic biomass •Crop residues •Dedicated energy plants: switchgrass, miscanthus, willow, poplar LCA output attributes should be relevant to energy and environmental concerns ethanol has been extensively investigated in life cycle assess-ment(LCA) studies,mainly from a transport bio-fuel perspec-tive (Fu et al.
