Since October 1996, NKK has been operating a recycling system of industrial waste plastics as raw material for blast furnace. This NKK's recycling technology, in which waste plastics are used as a substitute for coke, a reducing agent of iron ore, has been officially authorized as a recycling method under the PWRL (Packaging Waste Recycling Law), and is now going to be applied to recycling of waste plastic packaging. A new technology of removing impurities, especially PVC, has become a key element in applying recycling system of waste plastic packaging to blast furnaces. Both at Fukuyama and Keihin Steel Works, NKK has constructed a new treatment plant to cope with the full implementation of the PWRL in April 2000.
