The analytical method used was life cycle assessment (LCA). Methodological issues when using LCA for assessing the climate impact of biorefinery LCA system boundary: switchgrass to ethanol 10 .

performed a life cycle assessment (LCA) of ethanol production via bioconversion of willow biomass crop feedstock, where steam explosion was used as a pretreatment step, and cellulose and hemicellulose were converted into monomeric sugars by enzymatic hydrolysis prior to the fermentation into ethanol . CORSIA supporting document — Life cycle assessment methodology - 2 - This CORSIA supporting document provides technical information and describe ICAO processes to The proposed framework is demonstrated with a case study of tree ethanol pathways (maize, sugarcane and willow). Study shows that carbon mitigation assessment through LCA is possible and that it could be a useful tool for decision makers as it can compare different projects regardless of their original context.

This is uncommon for LCA software, where other main software packages are closed source, with costs for a business licence of several thousand Euros. One reason for its development was to make LCA and Sustainability Assessment more accessible and affordable, and we are grateful for supporters for the project, initially in Europe and later on especially in the US. Before the reactor, the ethanol passes through two heat exchangers. In both exchangers, it is heated by a countercurrent flow of reactor product, which passes the exchangers before undergoing purification. However, before entering the second exchanger the ethanol is mixed with an ethylene-water vapor recycle from the reactor product.

This study summarizes the LCA studies on lignocellulosic ethanol produced from various biomass resources focusing on energy balance, greenhouse gas (GHG) emission and other impact categories, and LCA of Ethanol Production and Use: the Lombardy (Italy) Case Study Costanza Scacchi, Stefano Caserini AIAT, Milano INTRODUCTION The environmental impacts of biofuels are very variable They depend very much on location, farming techniques, transformation pathways, and final use of by-products A case-by-case assessment might be required LCA practitioner : General Purpose: Excerpt from the report, see ’Publication’: The production process starts with cane cultivation, ethanol production, ethylene production, polymerization, use phase (which is not included in the study) and ends with incineration. Life Cycle Analyses (LCA) are used to compare biofuels to fossil fuels. These analyses are made according to the ISO 14040-43 standards, which using a defined unit compare mass and energy balances for two or more comparison objects.In Spain, the The 2015 LCA of products from the wood-based biorefinery at Borregaard, Sarpsborg.
