Chemical Recycling of Household Polymeric Wastes
Description
This chapter provides insights on the disposal of household polymeric wastes and chemical recycling of household polymeric wastes for chemical feedstock. Waste generated may cause environmental, economic and health problems. In 2012, the EU (European Union) generated 2514 million tons of waste, of which 213,410 million tons is household waste. Household waste has lots of polymeric materials. The two most important of the polymers are polystyrene (PS) and low-density polyethylene (LDPE). In this study, the results of PS and LDPE obtained from various processes related to polymeric wastes’ chemical recycling were given. Main products of PS chemical recycling were obtained as follows: styrene monomer, toluene, ethylbenzene, α-methyl styrene and other valuable chemicals. When LDPE undergoes thermal degradation in a solvent setting in autoclave, oil like diesel can be obtained.
