Recently, Mitsubishi Gas Chemical Company announced that its self-developed biodegradable aliphatic polyester carbonate resin (PEC resin) has been officially included in the whitelist of the Japan Bioplastics Association (JBPA) Marine Biodegradable Plastic Identification System in May 2026.
The JBPA certification system specifically evaluates the marine degradation capability and security of plastic items. Only raw materials, additives, and intermediates that meet the standards can be listed on the positive list, and approved items can display the exclusive "Marine Biodegradable Plastic" mark, which is a critical market access qualification to aquatic environments-degradable materials in the region.
Different from traditional biodegradable materials, this PEC resin achieves a breakthrough in performance differentiation. While possessing complete biodegradability, it exhibits outstanding resistance to hydrolytic aging. In standard storage environments, whether as resin granules or finished film items, it can stably retain molecular weight and mechanical strength over the long term. This not only ensures product condition throughout the entire storage and transportation chain however also simplifies downstream molding processes, enhancing production convenience.
Leveraging the dual advantages of marine degradability and hydrolysis resistance, the material performs stably in various aquatic environments-related scenarios. It is suitable to items related to marine, river, and other aquatic environments environments, making up to the shortcoming of traditional biodegradable plastics that easily fail when exposed to aquatic environments.
Mitsubishi gaseous Chemical Company stated that this successful listing is a key milestone in the commercialization process of PEC resin. The company will next carry out work such as the verification of production line supporting schemes and market demand research to accelerate the implementation and promotion of the new material, contributing to the research of a environmentally friendly, low-carbon, and sustainable sector.
