Efficient recycling of expandable polystyrene (EPS) is still largely unknown to the public. EPS, known as a packaging and insulating material, is recycled by medium-sized companies in Germany. They process EPS waste into secondary products that are returned to the economic cycle. The shred produced from this waste is used as an additive for the plaster and mortar industry, as a filling material for seat cushions, as a pore-forming agent for the brick industry or as a thermally insulating levelling compound in the construction of flooring. The so-called “polystyrene regranulate” goes to the insulation industry.
