Poly waste management

These environmentally degradable polyolefins, because of their cost/ performance profiles are very competitive for the growing markets for such plastics. They will be strong competition for the polyester types such as poly(lactic acid) and polyhydroxyalkanoates so frequently publicized as the innovative solution to plastic waste management. 

These criteria reflect a strong empathy with the need to address the environmental aspects, and Vink demonstrated the positive benefits that poly (lactic acid) could achieve, both in terms of the manufacturing process, as well as the waste management disposal options at the end of a product s useful life.

One possible way of polymer waste management is the chemical modification of polymeric materials. Sulkowski et al. (2013) used expanded polystyrene waste (EPS), as the reference material, which was converted into polymeric flocculants by the sulfonation reaction. Under conventional heating and microwave conditions, poly(styrenesulphonate) acids (EPSS) were obtained from EPS during the sulfonation process with sulfuric acid as the sulfonation agent and Ag SO as the catalyst. It was observed that the sulfonation process performed under microwave irradiation gave same amount of product as in case of conventional conditions but the reaction time was substantially reduced from 1-1.30 h to 15 min.
