Sustainable acoustic and thermal insulation materials from elastomeric waste residues

This presents a novel technological route to transform waste from the shredding of tyres, car bumpers and carpets into acoustic and thermal insulation materials that match or even outperform commercial products. The approach is to bind the waste particulates with a foaming polymer, the chemistry of which is manipulated to control structure stiffness and evolution of the foaming gas into open cells (for acoustic insulation) or closed cells (for thermal insulation). This research was funded by the DTI Technology Priority Initiative on Design & Manufacture of Sustainable Products Landfill. Anglo Felt Industries has now taken up the technology.
