With the unprecedented development of industrial society, the production of plastic waste has been an overwhelmingly growing domain and accordingly, it is reasonable to find that the increasing research focus has been drawn to post-consumer plastic products including thermoplastics (such as polypropylene, polyethylene, polyethylene terephthalate (PET) and high density polyethylene (HDPE)). In essence, plastics form a considerable portion 5–15% of municipal solid waste by weight, which equals to 20–30% volumetric proportion (Bazargan et al., 2013). It was reported that in 2011, total MSW (municipal solid waste) generation was 250 million tons in the United States thus it can be estimated that the PSW (plastic solid waste) disposed is around 25 million in weight (Gug et al., 2015). Meanwhile, the proportion of plastic waste in total MSW significantly expanded from 0.5% to 12.5% between 1960 and 2010. These statistics reveal that beneath the convenience due to wide use of plastic products, people should be alarmed about the challenges of white pollution and accompanying environmental issues created by plastic waste.
