Ethanol production in biorefineries using lignocellulosic feedstock - GHG performance and energy balances

Ethanol production in biorefineries using lignocellulosic feedstock - GHG performance and energy balances

Sustainability performance of biofuels is often evaluated using life cycle assessment (LCA). Based on this method standardized guidelines has been laid down in the EU Renewable Energy Directive (RED), commonly used by the industry. Biorefineries producing a variety of co-products, poses particular challenges for the sustainability assessment methodologies.

In the f3-project Co-production of ethanol and biogas, the GHG performance of ethanol and biogas co-produced in biorefineries from a lignocellulosic feedstock were calculated, applying the RED methodology.

The aim in the present project was to study aspects which are not included in the RED methodology. A specific emphasis was laid on methodological choices such as handling of co-products, functional unit, system boundaries etc. The results and methods are also discussed in relation to the RED methodology.

The results can be used to identify future research needs, but also be useful for future policymaking regarding e.g. use of lignocellulosic feedstock or biorefining and for industry.

An article from the project has also been published in Journal of Cleaner Production, access it here.
