Rengo Subsidiary Sun･Tox to Develop Biomass PP Film
Rengo Co., Ltd. announces that Rengo subsidiary Sun･Tox Co., Ltd. acquired International Sustainability & Carbon Certification (ISCC) for all its plants (Kanto Plant and Tokuyama Plant) in October 2021. The certification is based on a mass balance approach and Sun･Tox will develop biomass polypropylene (PP) film that partially uses certified biomass raw materials. This certification ensures the traceability of mass balance in the supply chain, enabling the issuance of a Sustainability Declaration. Sun･Tox has sold environmentally friendly film using biomass polyethylene (PE) for several years, and through the development of biomass PP film using this mass balance approach, the company will be able to supply more environmentally friendly products.
Rengo Group will expand its range of environmentally friendly products and contribute to society through the realization of SDGs.[About ISCC Certification and the Mass Balance Approach]International Sustainability & Carbon Certification (ISCC) is an international certification which conforms to EU guidelines for renewable energy. The mass balance approach is a method of allocating biomass derivation, according to the amount of biomass-derived input, to a portion of products where biomass-derived raw materials and petroleum-derived raw materials are mixed together in the process of processing raw materials into products (in this case, the production of film). Biomass is a renewable resource that is derived from plants and animals and can be used sustainably.
