How can polyurethane (PUR) insulation materials from old refrigerators be returned to the material cycle on an industrial scale instead of being used to generate energy? The recycling of this post-consumer waste is the focus of a collaboration between KraussMaffei, RAMPF, REMONDIS, and BASF.
Refrigerators have a long lifespan. To ensure energy efficiency and as little CO2 emissions as possible, manufacturers of almost all appliances all around the world rely on the insulation performance of polyurethane. PUR is an energy saver during its service life. But what happens at the end of the life cycle when the refrigerators and thus ooy IEX vauvx zyqt bwfh oqug arefm nrl?
