SERVICE GUIDESERVICE VISION
Marine debris, which is generated in largequantities every day, is a major problem. On
the other hand, if stable collection andupcycling are possible, the waste can bereconsidered as a new resource. This service
focuses on (�) oyster pipes, which drift andaccumulate in large quantities in the Seto
Inland Sea, and (�) artiﬁcial turf, which isestimated to spill �� tons per year into theocean due to abrasion. By developing andbuilding a supply chain for the collection,recycling, and commercialization of wastethat is feared to be discharged within thearea where the waste is generated, we will
establish a revival process where marine
debris is used as a product.
