In the present invention, there is disclosed an expanded polystyrene molding, particularly shaped expanded polystyrene molding containing 20 to 95 percent by volume recycled polystyrene beads (1) and/or polystyrene crushed material (2) and 5 to 80 percent by volume new polystyrene beads (3), wherein the size of said new polystyrene beads (3) is at least 1/3 less than the size of the recycled polystyrene beads (1) and/or polystyrene crushed material (2), wherein said new polystyrene beads (3) are located in spaces that are made between the recycled polystyrene beads (1) and/or polystyrene crushed material (2), wherein the mixture of the recycled polystyrene beads (1) and/or polystyrene crushed material (2) and the new polystyrene beads (3) is dry at the moment at which it is filled in a mold (4). A process for producing moldings of expanded polystyrene, particularly process for producing an expanded polystyrene molding is characterized in that a mold (4) is filled through whirling motion with 20 to 95 percent by volume dry recycled polystyrene beads (1) and/or dry polystyrene crushed material (2) and 5 to 80 percent by volume dry new polystyrene beads (3), wherein the size of said new polystyrene beads (3) is at least 1/3 less than the size of the recycled polystyrene beads (1) and/or polystyrene crushed material (2). Subsequently, the content of the mold (4) is heated by steam thus causing interconnection of surfaces of the |
