日本钢管公司(NKK)京滨厂1号高炉(内容积4907m~3)首次采用了向高炉喷吹废塑料的联合处理系统。该处理系统共投资15亿日元。每年约有3万t的废塑料,经收集、分类、粉碎及造粒后由风口喷入高炉。尽管喷吹废塑料的第一个实际操作厂是在日本,但首先研制这一技术的是德国的不莱梅钢厂。所收集的废塑料包括瓶子,个人计算机部件及磁带等。象瓶子这样的固体废料,首先粉碎 Japan Steel Tube Company (NKK) Keihin Factory No. 1 blast furnace (content 4907m ~ 3) for the first time used to blast the waste plastics injection joint processing system. The processing system invested a total of 1.5 billion yen. Each year about 30,000 tons of waste plastics, after collection, classification, crushing and granulation after blasting into the blast furnace. Although the first actual plant to blow waste plastics was in Japan, the first such plant in Germany was the Bremen mill in Germany.
