Nippon Steel Made in 7 bases, such as the Kimitsu area (Kimitsu City, Chiba Prefecture), has been increasing the processing of abandoned plastic from 2022 from 2022.The development of technologies to high density and reduce plastic collected by local governments.With the enactment of plastic resource recycling promotion laws, the treatment of general waste plastic is likely to increase, and the company plans to expand its business through its own processing method with a 100 % recycling rate.
Nippon Steel made a technique to increase the density when cutting the collected abandoned plastic after cutting.It is a technology that can modify a reduced molding machine to efficiently squeeze from a narrow mouth and to properly control the temperature of frictional heat when squeezing out.
The company has more than 20 years of processing based on the Plastic Container Packaging Recycling Law.In FY2010, about 330 local governments made a successful bid, processing 2006,000 tons, which was flat compared to the previous year.It is equivalent to about 30 % of the total processing of the local government to be collected.In the Plastic Resource Recycling Promotion Act, which will enforcement in April 2012, in addition to container wrapping plastic, product plastic such as hangers and buckets will be collected on local government routes.
The recycling of abandoned plastic is a granularized plastic with coal in the coke reactor, which creates coke, a reducing agent for iron production.After heat decomposition, it is used as a hydrocarbon oil and coke furnace gas as a plastic material.The chemical method used by Nippon Steel has a recycling rate of 85 % or more.
Nippon Steel is developing a recycling business of abandoned plastic at Muroran, Kimitsu, Nagoya, Yawata, Oita, Kashima and Wakayama.It is necessary to stabilize the processing amount so that it does not hinder coke production in recycling of abandoned plastic, and the technical improvement is proceeding steadily.
The government has set a goal of reducing disposable plastic by 30 years by 25 % and recycling 60 % of container packaging plastic.Currently, only about 70 % of local governments participate in the collection of container packaging plastic.It is noteworthy how the effectiveness of recycling increases in the enforcement of the Plastic Resource Recylation Promotion Law.
