Closed cell foamed polystyrene beads are shredded to form small size, open-celled foam particles. The particles are mixed with a slurry of a granulate and a liquid whereby the slurry enters the open cells to increase the density of the particles. After an even distribution of the particles throughout the slurry is obtained the mixture is dried to form granulate objects, such as boards, having an even distribution of foamed polystyrene particles therein to reduce the density of the object.
