USE OF POST-LIFE WASTES AND PRODUCTION WASTES IN THERMOPLASTIC POLYMER COMPOSITIONS

摘要

Voluminous post-life wastes and production wastes pose the paramount environmental problem of our times. One major problem is how to reuse post-life wastes: spent plastics, rubber scrap, mainly worn-out automobile tyres, waste paper and production wastes: wood pulp or powder and particularly the wastes arising in the production of fertiliser, the phosphogypsum. At ICRI we have been conducting studies on reutilizing these wastes by using them as individual or combined additives in polymer compositions which are prepared as blends with virgin and also with end-of-life recycled polymers. These novel compositions can serve for following applications: 1. porous pipes intended for irrigation or fertigation. 2. vehicle parts in the automobile industry. 3. tiles or floorings in the building industry. 4. road safety and traffic control equipment. 5. sound-absorbing screens in the deafening facilities erected along motorways. 6. packing in biological wastewater treatment. 7. biodegradable flower pots buckets, fence elements and like profiles.
