Valorising biomass into multifunctional air filters – step 1

Racoon, an innovative SME, offers a unique technology that provides multi-functional air filters aiming harsh environments such as mining, waste and recycling industry. Their filters have a special coating offering both removal of dangerous gases and deactivation of harmful pathogens. Within this high-risk project, Racoon together with RISE, are interested to test the hypothesis of exchanging the petroleum-based foam that forms the structure of the filters with a new material that is not only bio-based but also a rest product from another industry.

Racoon teams up with RISE to explore the use of selected biomass residue as the base material for their coating, replacing the polyurethane-polyester blend foams that are currently used. This circular and sustainable ecosystem (sustainability proposition) of utilizing waste products from one industry, combined with the multi-functional coating from Racoon will make this new sustainable product stand out among the competition as a high-value, multifunctional product.
