Construction of the resource circulation system which used the factory as the core

Abstract: Sekisui House, Ltd. constructed a zero-emissions recycling system which enables 100% recycling of construction wastes discharged from the company's construction sites. In this system, all construction wastes are recovered at the company's plants, completely sorted, and consigned to recycling facilities for treatment. Sekisui House has maximized sorting accuracy by adopting a 2-stage sorting system consisting of sorting into 27 types at the construction site, followed by sorting into 60 types at the company's factories. The sorted wastes are then consigned to the most appropriate facility for treatment, depending on the individual properties of the material, which makes it possible to trace wastes effectively in all processes from generation to recycling as raw materials. A zero-emissions system which secures traceability can be considered an ideal form for recycling systems. From the viewpoint of supply chain management (SCM), the company is endeavoring to establish SCM for the physical distribution of waste
