TY - JOUR AU - Niemetz, Nora AU - Kettl, Karl-Heinz PY - 2012 DA - 2012/09/04 TI - Ecological and economic evaluation of biogas from intercrops JO - Energy, Sustainability and Society SP - 18 VL - 2 IS - 1 AB - Biogas made from main crops (e.g., corn) is commonly used for producing electricity and heat. Nevertheless, the production of energy from monocultures is highly unsustainable and not truly renewable. Since neither monocultures nor food competition are desirable, intercrops can be used to increase the yield per hectare instead of leaving agricultural fields unplanted for soil regeneration. The extra biomass can be used for biogas production. In a case study, the economic as well as the ecological feasibility of biogas production using intercrops, cattle manure, grass and corn silage as feedstocks for fermenters was analyzed.
