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.

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 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.

A number of studies on LCA of fuel ethanol have been conducted, and the results vary to a large extent. In most of these studies, only one type of allocation is applied. ethanol production • Our life cycle study asks if the benefits of carbon recycling and fossil energy avoidance can be properly balanced against the lost opportunity for sequestering carbon in soil and improving soil health.
