Air filter from recycled bio-based materials - BioReFil


MoRe is involved as a scale-up party in an exciting project on filters for air purification, BioReFil. Sara Wallstén and Forough Momayez represent MoRe Research in this project funded by Bioinnovation. Other parties are RISE, Oppigård AB, Racoon Miljöfilter AB, Sharetex.

Air purification is a big and topical issue, with applications in both indoor climates and the automotive industry. Many air filter materials are based on fossil raw materials. The main aim of this project is to further develop and construct bio-based filter materials, based on residual products from the brewery process and recycled cellulose.

The market for air purification applications is large and growing. This applies both to indoor climates, especially in the aftermath of Covid-19, and to the automotive industry where both drivers and electronics depend on good air quality. Many filter materials used today are based on fossil raw materials, which is unsustainable in the long run. This project aims to develop sustainable alternatives based on the reuse of textile materials and residual products from brewery processes and includes the entire value chain from raw material producers to end users.

Recycled textile materials are a so far underutilized resource. Largely because the recycling processes are still under development and also because areas of use have not been established. In this project, cellulose material produced via ShareTex's process will be used, where the fibers are purified from textiles via a unique method.
