Recycling and Degradation of Polymers

It is desired to recover plastics waste and reprocess or use the product of the reprocessing as raw material or fuel. Currently, plastics are subjected to any one of the following options  

Plasties materials are dumped however, with the increasing cost of land, this is becoming uneconomical. In addition to this, there is total wastage of the material and energy (assuming that the polymer could be burnt as fuel) [29,30]. 

Plastics are recycled but during the recovery stage, the polymers (particularly in the ease of mixed plastics such as composites) lose quality and texture due to partial degradation, which invariably occurs during the recovery stage. 

The plastics are burned as a municipal waste in incinerators or in steel plants. In this recycle technique, the energy of combustion is recovered and utilized, but the material is lost. 

There is considerable economic interest currently in the complete degradation of plastics and recover higher-valued products because of high dumping cost and stringent legal requirements of pollution. Unfortunately, monomers cannot be
