The plastics and rubber waste was recycled and processed to polymer-matrix composites reinforced with phosphogypsum waste, glass and cellulose fibers, wood dust, rape straw, as well as disintegrated carpet, packaging and leather waste. The composite materials were used as porous pipes for irrigation, road safety devices, selflevelling floors, floor-linings, acoustic baffles, geogrids, geonetwork and various small goods (pots, boxes).
