Life Cycle Assessment of Biogas from Separated slurry

This study, entitled “Life Cycle Assessment of Biogas from Separated slurry” was commissioned by the Environmental Protection Agency of Denmark. It consists of the continuation of the project entitled “Life Cycle Assessment of Management Technologies”, available on Environmental Protection Agency of Denmark website (project no. 1298, 2009) and references to it are made several times throughout the present study.

The outcome of this project consists of the present background report and 4 life cycle inventory annexes detailing all the calculations, assumptions and data used for the life cycle assessment of the different biogas production scenarios.

The project has been carried out by Lorie Hamelin, Marianne Wesnæs and Henrik Wenzel from University of Southern Denmark in cooperation with Bjørn Molt Petersen, Department of Agroecology and Environment, Faculty of Agricultural Sciences, Aarhus University.
