초록
Biogas plants using food waste and other organics as a substrate to produce biogas for energy utilization were analyzedfor their economic feasibility. In the case of anaerobic digestion of food wastes alone, the economic feasibility of biogas productionwas quite low. Therefore, it is essential to increase the government subsidy for the construction of biogas facilities. In the case of foodwaste leachate, it was economically feasible without government support. Currently, approximately 30% of food waste leachate wasprocessed in the biogas facility. The number of them are expected to increase gradually in Korea. The co-digestion of food wasteleachate and livestock manure was not economically feasible, but it is expected that the number of facilities will increase as thegovernment subsidies can compensate the loss. The co-digestion of food waste and food waste leachate will help improve theeconomics of food waste biogas facilities. Among the food waste and other organic treatment processes, biogas production from foodwaste leachate by co-digestion was found to be more feasible than the other options. Overall biogas production using food wasteleachate should be encouraged continuously by government.
Abstract
Biogas plants using food waste and other organics as a substrate to produce biogas for energy utilization were analyzedfor their economic feasibility. In the case of anaerobic digestion of food wastes alone, the economic feasibility of biogas productionwas quite low. Therefore, it is essential to increase the government subsidy for the construction of biogas facilities. In the case of foodwaste leachate, it was economically feasible without government support. Currently, approximately 30% of food waste leachate wasprocessed in the biogas facility. The number of them are expected to increase gradually in Korea. The co-digestion of food wasteleachate and livestock manure was not economically feasible, but it is expected that the number of facilities will increase as thegovernment subsidies can compensate the loss. The co-digestion of food waste and food waste leachate will help improve theeconomics of food waste biogas facilities. Among the food waste and other organic treatment processes, biogas production from foodwaste leachate by co-digestion was found to be more feasible than the other options. Overall biogas production using food wasteleachate should be encouraged continuously by government.
