Recycling solutions for refrigerators
ANDRITZ MeWa recycling plants for cooling devices can reclaim 99.9% of environmentally harmful greenhouse gases. A particular benefit is that even modern refrigerators – in which the insulation materials have been expanded using highly-explosive pentane gas – can be processed safely at the same time as CFC appliances (no risk of fire).
The completely sealed system of the universal cross-flow shredder QZ takes in the refrigerators in batches and breaks them down into their individual components. A subsequent matrix degassing unit extracts the CFCs from the insulating foam. With this gentle and environmentally friendly method of processing, the ANDRITZ MeWa recycling plants for refrigerators comply with highest European environmental standards. The individual iron, copper, aluminum, plastics, and polyurethane foam fractions extracted can be returned directly to the economic cycle.
