Manufacturers of caravans and leisure vehicles are exploring alternatives to traditional plywood. The material Supersede, a structural panel made entirely from recycled industrial plastic, is being developed as a direct replacement for marine-grade plywood and oriented strand board. Production is backed by Closed Loop Partners, and the material is already used in the leisure vehicle, marine, and modular housing sectors. The panels are fully waterproof, require no sanding or sealing, and offcuts can be recycled back into production.
