Morales, Quintero, Conejeros, and Aroca (2015) reviewed 60 LCA studies of lignocellulosic ethanol produc- in Ontario. Life cycle assessment (LCA) methodologies have been used to evaluate the LC of ethanol to determine if environmentally preferable and economically viable ethanol can be produced in Ontario, Canada.

The results of the environmental impacts were compared to others LCA studies of biofuel and it was showed that there are significant differences of environmental performance among the existing … assessments (LCA), Farrell and colleagues (10) found that current corn ethanol production yields an NEV of ap-proximately 5 MJ L-1 and a GHG intensity of -18% (uncertainty range: -36% to +29%) compared with that of conventional gasoline. Similarly, ethanol derived from both switchgrass and corn stover has been shown to have higher Among the different platforms, there are two obvious advantages to using lignocellulosic biomass for ethanol production: higher net energy gain and lower production costs. 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.

Greenhouse  Production of rapeseed oil, rape methyl ester (RME) and ethanol fuel for heavy diesel engines can be carried out with different systems  av M Martin · 2011 · Citerat av 2 — reference energy systems used in life cycle assessment of biofuel biogas and ethanol production plants will be assessed by comparing  The greenhouse gas (GHG) emissions of the life cycle are 17.45 gCO2e per MJ of ethanol produced. In comparison to gasoline, this results in a 78% reduction  small-scale production of ethanol for heavy engines under Swedish conditions.

Grain-based ethanol production uses a range of process fuels. Ethanol plants also produce distillers’ grains, corn oil, and other food and feed products. Ethanol also is a higher-octane blending component which reduces the GHG emissions associated with crude oil refining. For each of the analyzed systems, the study compares the LCA results of the pulp and bio-ethanol production systems in the baseline scenario (B1, B2, and B3), corresponding to the current closed-loop process, with the innovative scenarios where the lignin is partially removed from the production process as a co-product of bio-ethanol and paper (scenarios B1*, B2*, and B3*). 2021-02-16 · Background The key problem of non-grain energy plants’ scale development is how to estimate the potential of GHG emission reduction accurately and scientifically.
