Development and characterisation of novel structural composites from recycled materials
Carpets are composite materials and, like many composite materials, waste carpet is both difficult and expensive to recycle because of the complicated, multi-stage processes involved. In the UK, approximately 400,000 tonnes of carpet waste are sent to landfill annually. However, the landfill option …
