The increasing use of plastic materials in different industrial fields is essentially due to their unique characteristics. This spreading has brought to the dispersion of plastic materials, fragments and objects in the environment. Furthermore, an insidious kind of pollution, strictly connected to plastics, is constituted by the presence in the environment of microplastics, commonly defined as “plastic particles < 5 mm in diameter, which include particles in the nano-size range”. During the last decade, several studies have been conducted on their removal from discharge or drinking water. This topic is currently trending and even companies are showing a marked interest in this issue.
