With growing concerns on increased waste emissions, depleting capacity for final disposal which triggered calls for new regulations on resource managements in the society, Japan PVC Pipes and Fittings Association (PPFA) started a voluntary recycling system proactively to retain flexibly in system operation and modification for efficiency and to avoid regulations which could be rigid. The system was successfully recognized by relevant laws as means to promote recycling. The voluntary action also contributed to improve the image of vinyl products. A key for success was to design a system which benefits both the PVC pipes and fitting industry and the existing companies engaged in waste treatment, processing, and recycling. To increase the amount of recycling, it was essentially important to develop a system in a way that quality post-use products were stably collected and the manufacturers of products made with recyclates could find customers. Coordinated measures needed to be taken including development of an efficient nationwide network for collection of waste products, preparation of quality guidelines for collection of wastes, information sharing with potential partners including local government bureaus in charge of installation and maintenance of water supplies or sewer, and developing national standards for products to ensure the quality of products.
