The waste film generated at film pro-cessing manufacturers is clear and colorless and is used by the manufac-turer to be reused back into raw ma-terials in the process. The waste film generated at packaging converters is no longer used due to poor printing or design changes and is recycled only for pallets and cap-shaped products that can be reduced to black or oth-er dark colors. In addition to printing, many packaging materials that are combined with various types of films are also recycled into pallets, etc. In addition, many of them are incinerated as industrial waste to be used as fuel for boilers or power generation.Kenji Miharu, leader of the Con-verting CoE Promotion Group, says, “In Japan, incineration is regarded as thermal recycling. However, we have received strict opinions from Europe and the United States that incineration cannot be recognized as recycling be-cause plastic cannot be used as raw material again. In other words, a recy-cling system for flexible packaging ma-terials has not yet been established in Japan.”The company’s concept of resin re-cycling for flexible packaging materials is to collect waste film from converters as a resource and manufacture and sell pellets that ensure horizontal recy-cling into food packaging film. This can contribute to the reduction of waste plastic and reduce the industrial waste cost burden for converters. In addition, the company plans to provide plastic processors with high-quality recycled materials that can be horizontally recy-cled into food wrapping material.The company’s flexible packaging Impact of Plastic Containers and Packaging on Waste Plastic EmissionsMitsui Chemical’s concept of plastic recycling business31Benefits for converters and resin processing manufacturerRegarding the recycling of flexible packaging materials in Japan, the es-timated market size of flexible packag-ing materials is approximately 2 million tons. Of this, 300,000 tons are PIR (Post-Industrial Resin/Post-Industrial Recycled: resin recycled from waste generated in the manufacturing pro-cess), which is generated as defective products from each factory, and PCR (Post-Consumer Recycled Resin, a resin recovered and recycled from waste discarded from end-user, which is used waste film) is estimated to be approximately 1.7 million tons.
