In order to achieve a high substantial utilisation quota, the latest process technology is necessary. In the worldwide only plant for the recycling of PU foam cans in Thurnau, the cans are mechanically shredded out of contact with air. The liquid contents and the metal can parts (aluminium and tin plate) drop into a solvent bath. A rinsing screw brings them out again and they are pre-washed with the aid of rinsing jets.
Further washing stages follow. A metal cutter sorts out the cleaned and dried aluminium and tin plate. The produced PUR solvent mixture is filtered several times and separated between PUR and solvent. The propellants are extracted above the shredder and filled into pressure cylinders. The plastic tops of the cans are available coarsely ground for the plastic processing.
