Abstract
Voluminous post-life waste and production waste pose the paramount environmental problem of our times. One major problem is how to reuse post-life waste: spent plastics, rubber scrap, worn-out automobile tyres, waste paper and production waste; wood pulp or powder and particularly the waste arising in the production of fertiliser, phosphogypsum. We have been studying the re-use of these wastes as blends with virgin and recycled polymers. These novel polymer compositions can be used to make:
• porous pipes intended for irrigation or fertilization.
• vehicle parts in the automobile industry
• tiles or flooring in the building industry
• road safety and traffic control equipment
• sound-absorbing screens along motorways
• packing in biological wastewater treatment
• biodegradable flower pots, buckets, fence elements and similar profiles.
