| 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. |

| It is very much debated whether bioethanol is a sustainable energy resource that can offer environmental and long-term economic advantages over fossil fuels, like gasoline or die-sel. From the present first generation bioethanol technology focusing on starch (from grain) fermentation GHG savings are only modest. The Danish Integrated Biomass Utili-sation System (IBUS) has developed both first generation and second generation princi-pal bioethanol technologies characterised by integration with an existing coal-fired Com-bined Heat and Power (CBH) plant. To secure that bioenergy is produced from local adapted raw materials with limited use of non-renewable fossil fuels there is a need for integrating the biomass starting point into the energy manufacturing... |
