Abstract
A new resin recycling process has been put into commercial operation at two Nippon Steel's steel works in 2000. The new process is composed of the waste package plastics processing plant (WPP) that has been newly planted, and the existing coke batteries in that the processed resins are thermally cracked. The WPP is designed for removing the foreign matters form the contaminated waste plastics and making agglomerates of the waste resins. The crashers, sorting devices and compactor are arranged in the processing line so as the total plant functions effectively. The WPP properly processed a waste resin source from a city waste plant, which contains relatively large amounts of the foreign matters, during the test operation. A waste package resin source that is 97% pure resin is also processed very effectively. The WPP processed this waste resins at the designed production rate, 8 tons per hour.
