219 LCA food waste utilization system with consideration to regional treatment

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 regional areas, the recycling and energy utilization system was evaluated by LCA. First, We carried out the case study based on the knowledge of reducing the environmental impacts of a processing system with selection of recovery area and cooperation with an existing infrastructure like a garbage processing plant. As a result, It turned out that it is most excellent that we perform a methane fermentation institution on the basis of less than 20 km in radius.
