Development of a platform dedicated to the mechanical recycling of styrenic polymers, focusing on the recovery and transformation of expanded polystyrene. Through an advanced production process, the waste material is regenerated into crystal polystyrene (r-GPPS) and expandable polystyrene (r-EPS). The obtained r-EPS is blended with EPS from other plants, resulting in an expandable product that integrates a portion of recycled material, ensuring quality and sustainability.
