The world's first biomass-balanced polyethersulfone (PESU)

BASF has introduced the world's first biomass-balanced polyethersulfone (PESU), Ultrason® E 2010 BMB. This innovative material replaces fossil feedstock with renewable alternatives derived from organic waste, using a certified biomass balance approach. It is a drop-in solution, meaning it offers the same properties, performance, and certifications as the standard Ultrason® material, making it an easy transition for industries like automotive, electronics, healthcare, and household goods to adopt.

The new Ultrason® E 2010 BMB allows customers to reduce their environmental impact by cutting greenhouse gas emissions and increasing the use of renewable feedstock without sacrificing product quality. This material is particularly suitable for products such as reusable bottles, microwave dishes, automotive fuel parts, and medical devices, all of which benefit from its sustainability advantages. BASF’s commitment to transparency also helps customers assess the product's carbon footprint through readily available data.

BASF produces this biomass-balanced PESU using 100% green electricity in a resource-efficient process at its plant in Ludwigshafen, Germany. The renewable feedstock replaces 50% of the fossil materials in the production, resulting in a significant reduction of the product’s carbon footprint.

This innovation is not only a step toward greener manufacturing but also provides a practical solution for industries striving to meet sustainability targets without the need for new processing lines. BASF’s biomass-balanced Ultrason® is designed to seamlessly integrate into existing production workflows while supporting a transition to more circular solutions in a variety of industries.
