InSus has started recycling PIR and PUR sandwich panels. The steel and aluminium residues are collected and made suitable for reuse. The propellants are captured, (H)CFCs are stored and rendered harmless. Pentane gas is returned to the production process. PIR and PUR residues, depending on purity and impurities, are returned to raw materials that are used in the production of high-quality PIR insulation with low environmental cost indicator (MKI) registered in the Dutch National Environmental Database (NMD). For use in floors, pitched and flat roofs and cavity walls in new-build and renovation.
