Recycling of waste plastics and waste tires
NSSMC recycles 100% of plastic containers and packaging collected from general households by a chemical recycling process using a coke oven. To date, we have established an acceptance structure at six of our steelworks to cover all municipalities throughout Japan. They dispose of approximately 200,000 tons a year or 30% of what is collected nationwide. This amounts to an accumulated total disposal of approximately 2.5 million tons (from FY2000 through FY2015), which is equivalent to 7.9 million tons of CO2 reduction. Recently, chemical textiles and food trays are also being recycled by the same process for reuse as petrochemical products. Moreover, all discarded tires are recycled. At Hirohata Works, they are processed by a scrap melting method, which is a steelmaking process, and used as a fuel. They are also thermally decomposed in gasification recycling equipment for 100% reuse. The disposal capability is 120,000 tons a year. Approximately 10% of discarded tires in Japan are recycled.
