Microplastic-free biodegradable biopolymer

Kaneka Belgium NV announced that its Kaneka Biodegradable Polymer Green Planet™ Expanded Beads—type L40N—has been officially excluded from the definition of synthetic polymer microparticles under EU Commission Regulation 2023/2055.

Kaneka Green Planet™ is a 100% biomass-derived biodegradable biopolymer developed by Kaneka, as part of the company’s commitment to providing environmentally friendly solutions that do not rely on petroleum resources. It has shown excellent biodegradability in various environments and decomposes easily in soil and seawater, where it converts into CO2 and water.

Green Planet™ Expanded Beads are the result of integrating Kaneka's long-established Eperan™ particle foam technology with the development of Biodegradable Polymer Green Planet™. This innovative material is used in a wide range of lightweight, shock-absorbing applications, such as cushioning materials for home electric appliances, transportation containers for fresh food, and materials used in the automotive and transport industries. The foam particles can be processed with existing molding equipment, and their characteristics are similar to those of polyolefin foams.

The microplastic-free recognition of Kaneka’s Green Planet™ Expanded Beads follows a comprehensive assessment conducted by Normec OWS, an external verification laboratory. During the verification process, the product's aqueous aerobic biodegradability was evaluated based on CO2 evolution. The results indicated that the material achieves a mineralization level of +60% over a period of 28 days according to OECD test method 301 B. These results confirm that the product fully degrades without leaving any synthetic residues, reinforcing its role as a sustainable alternative in the foam applications industry and contributing to the fight against microplastic pollution.

"We are proud that Kaneka Green Planet™ Expanded Beads L40N have been officially recognized as microplastic-free in line with the highest environmental standards set by EU Regulation 2023/2055. This milestone reflects our dedication to protecting the planet and delivering eco-friendly particle foam solutions without compromising performance and quality. It will enable us to engage further with brand owners, molders, and consumers, and help us work towards a microplastic-free foam industry," said Luc Point, General Manager of Foam & Residential Techs EMEA for Kaneka Belgium.
