217 LCA of recycling and energy utilization system of food waste

Abstract

Effective use of food waste is needed from a viewpoint of recycling and energy utilization system. But, it is in the situation which is hard to say that sufficient measure is progressing, because of not to have evaluated objectively superiority such as recycling and energy utilization system, to differ in the conditions of a systems configuration with the local characteristic and so on. Therefore, in order to examine the effective use of food waste generated in urban areas, the recycling and energy utilization system was evaluated by LCA. First, we hypothesized that it is an efficient system of cooperation with existing infrastructure. And, we have estimated the environmental impact of various cases. As a result, we found that the sewage treatment plant to work with is more effective than a single installation of methane fermentation facility
