Because composite materials are made from binding two or more materials together, they can be difficult to recycle. Only 15% of the 110,000 tonnes of composites produced in the UK each year will be reused or recycled at end-of-life. And common composites such as carbon fibre or glass fibre use lots of fossil-based energy in their production. So, how can we keep using these incredible materials whilst reducing their impact on the planet? Dan Noakes, Grand Challenge Lead for Packaging at CPI, a deep tech innovation organisation in Teesside, UK, explores how we’re helping to make composites more sustainable: 1. Developing separating techniques to enable the raw materials to be recycled 2. Optimising the raw materials for reuse 3. Creating sustainable composites made from biopolymers rather than fossil fuels.
