In the past, used Styrofoam had to be disposed of. Nowadays, companies often work cooperatively on sustainable recycling processes, with the result that both expanded polystyrene and polypropylene are now 100% recyclable. Many of our customers rely on the work of PolyStyreneLoop, a non-profit organisation from the Netherlands. Members of the foundation are industry representatives from the entire value chain of polystyrene foam, for example PS foam manufacturers, raw material and additive suppliers, foam processors and recyclers. 74 companies and organizations are currently members of the cooperative. The basic principle is to keep resources in use for as long as possible and to reuse them as raw materials for new products at the end of their life span.
