It is an innovation among plaster products. Currently, there are problems with the disposal of hard polyurethane (PUR) foam at the end of its life cycle in landfills due to its low bulk density. Combustion is also used for its disposal. Both the PUR waste disposal options do not comply with environmental protection and sustainable development principles. We describe a novel application of hard polyurethane foam mechanically recycled in a forced-action mixer as a new extender for renovation plaster with heat-insulation effects.
