Mitsui Chemicals and Teijin team up to develop bio-based bisphenol A and polycarbonate resins
Mitsui Chemicals and Teijin jointly announced that they will be the first companies in Japan to develop and sell bio-based bisphenol A (BPA) and polycarbonate (PC) resins. These resins will support carbon neutrality by reducing greenhouse gas emissions throughout the product life cycle.
The joint action comes after Mitsui Chemicals obtained ISCC PLUS certification from the International Sustainability and Carbon Certification (ISCC), on the basis of which, Mitsui Chemicals will start supplying bio-based BPA produced using the mass balance method. In the ISCC PLUS certified mass balance approach, materials are verifiably tracked through complex value chains, such as bio-based raw materials being mixed with petroleum-based raw materials to produce products.
Teijin will also begin developing and producing bio-based polycarbonate resins using the same bisphenol A.
In May 2022, Mitsui Chemicals obtained ISCC PLUS certification for bisphenol A raw materials for polycarbonate resins. Mitsui Chemicals will now be the first Japanese company to produce a commercial bio-based BPA with the same physical properties as conventional petroleum-based BPA.
