Asahi Kasei Ester Plant, Nobeoka City, Miyazaki Prefecture Quiet Circulation Born from Existing Facilities: Late 1990s to Early 2000s
The chemical recycling of PET bottles at the Asahi Kasei Ester Plant in Nobeoka City, Miyazaki Prefecture, is a good example of a realistic response by a local plant at a time when Japan was still in the exploratory stage of creating a recycling-oriented society. However, it was difficult to recycle PET bottles for high-quality applications, and securing an outlet became an issue. Rather than introducing new equipment, Asahi Kasei built a system to manufacture high-purity polyester from raw materials derived from PET bottles by utilizing existing equipment that had originally reused yarn waste generated in its own processes. In Nobeoka City, which is a castle town of companies, this method of incorporating recycling as an extension of existing businesses is unique in that it enables stable operation while avoiding excessive investment. This case study shows that recycling-oriented businesses do not necessarily require large-scale investment, but can be realized by reinterpret
ing the technologies and facilities of existing industries.
