A short review: Potential use of plastic waste as adsorbent for various pollutants

Abstract

This paper reviews on the performance of different plastic waste as value-added adsorbent under different environmental pollution. As adsorbent, it should tender the uppermost rates of pollutant removal, cost-effective and easy to obtain. The first part of this paper discussed on the concept of adsorption process. Since adsorbents assortment is the key for adsorption study, the adsorption of dissimilar types of pollutants by different kind of plastic waste as an adsorbent are then reviewed in the following part. The use of different plastic waste of various types includes plastic carrier bag, coffee cup, plastic container and food packaging which are made from polystyrene, polypropylene, polyethylene terephthalate, high-density polyethylene, polyvinyl chloride and low-density polyethylene are highlighted in this paper. The advantageous of each plastic waste as adsorbent are discussed. It was found that they possess most excellent performance on the potential adsorption of pollutants in various environmental pollutants. It is believed that using of plastic waste not only provides a novel potential way to utilize waste plastics, but also put forward a facile sustainable approach in remediating environment pollution.
