Micro-billes bio-dégradables substitution micro-billes plastiques
Scientists and engineers from the Centre for Sustainable Chemical Technologies (CSCT) have developed a way of producing a biodegradable renewable alternative to plastic microbeads in a scalable, continuous manufacturing process.
The beads are made from cellulose, which is the material that forms the tough fibres found in wood and plants. In this process our scientists dissolve the cellulose to reform it into tiny beads by forming droplets that are then “set”. These microbeads are robust enough to remain stable in a bodywash, but can be broken down by organisms at the sewage treatment works, or even in the environment in a short period of time.
