POLYMEER

Challenge

Bioplastics make up only 1.5% of global plastic production, with projected growth insufficient to meet market needs. Brewers’ spent grain (BSG), a major by-product of brewing, is mostly used as low-value animal feed or ends up in landfills, adding to greenhouse emissions. Rich in fiber and protein, BSG has potential as a feedstock for bioplastics. However, current applications are limited by poor mechanical properties and lack of scalability. Developing high-value uses for BSG in bioplastics to replace fossil-based feedstocks remains a significant challenge.

Solution

POLYMEER aims is to develop new biobased polymers, copolymers and polymer blends based on BSG exploiting green, waste-minimised processes, expanding innovative alternatives to traditional plastics. The materials will undergo precise chemical design to meet a specific set of properties for three applications:  agriculture sector, tertiary packaging, and textile for the automotive industry. The new polymers developed within POLYMEER will be engineered to possess intrinsic recyclability and/or biodegradability.

Impacts

Scientifically, the project will drive innovation by developing new bio-based polymers with tailored properties and functionalities. It will promote economic sustainability by reducing reliance on fossil resources, lowering production costs, and creating new markets. This will enhance industry competitiveness, attract investments, and create jobs in the bio-based sector. Societally, it will raise environmental awareness and encourage eco-conscious consumer choices by providing sustainable alternatives to traditional plastics.
