Research on the collection and biogasification of biomass plastic (polylactic acid)

Abstract

Aiming for a resource-recycling society, the cyclical use of plastics is required. The government plans to increase the use of plant-based biomass plastics, such as polylactic acid and bio-polyethylene, to 2 million tons by FY2030. Although biomass plastics are made from plants, it is desirable to chemically recycle them after use rather than incinerate them. We are working on the biogasification of polylactic acid, which is relatively inexpensive and widely distributed among biomass plastics. This section introduces the status of efforts and test results.
