Socio-economic analysis of biogas and biogas combined with ethanol from organic agriculture

Summary

Two different scenarios of biogas production based on energy crops and manure and one scenario where the biogas production is combined with bioethanol production were evaluated with socio-economic analysis. The products from the biogas plants are heat and electricity as well as organic fertilizer. The socio-economic analysis compares the scenarios with a Danish organic farming reference scenario. There are several levels of analysis, where different external aspects are added in each level, e.g. externalities such as savings in CO2-emissions by replacing fossil fuels. The competition between use of land for bioenergy or for food is evaluated.
