Abstract Background Development of more sustainable biofuel production processes is ongoing, and technology to run these processes at a high dry matter content, also called high-gravity conditions, is one option. This paper presents the results of a life cycle assessment (LCA) of such a technology currently in development for the production of bio-ethanol from spruce wood chips. Results The

Between 2005 and 2015, ethanol production in the U.S. also increased significantly—from 3.9 to 14.8 billion gallons per year. At the same time, advances in ethanol production technologies, such as the use of combined heat and power, using landfill gas for energy, and co-producing biodiesel helped reduce GHG emissions at ethanol refinery plants.
�hal-02063823� A Case Study for Life Cycle Assessment (LCA) as an Energy Decision Making Tool: The Production of Fuel Ethanol from Various Feedstocks 982205 Life Cycle Analysis (LCA) considers the key environmental impacts for the entire life cycle of alternative products or processes in order to select the best alternative. 2020-07-29 · The disadvantages include high production cost resulting from high cost of feedstock, enzymes, detoxification and ethanol recovery, respectively.

We conducted a life-cycle assessment (LCA) of ethanol production via bioconversion of willow biomass crop feedstock. Willow crop data were used to assess feedstock production impacts. The bioconversion process was modeled with an Aspen CPM LCA Database - Ethylene production from cane based ethanol.

Our BAU scenario assumes a continuation through 2022 of current trends in average corn yields per hectare, process fuel switching from coal to natural gas, and increasing fuel efficiency in heavy -duty trucks. Based on these trends, we project life -cycle GHG emissions for corn ethanol in … 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.
Three fuels (ethanol, RME and biogas) have under certain conditions the technical The analysis will be based on LCA methodology and a computerised model,
