Mixed plastics waste recycling homogeneous fractions

An alternative method of recycling of mixed plastic waste is based on a separation of different components into homogeneous fractions. Sereni describes opportunities in this area and interesting industrial equipment required for effective separation of PET and PVC. 

A widespread solution, in terms of application and market volume, could be the recycling of single materials or homogeneous fractions obtained from a separation process of the mixture. In fact, the samples obtained from single homogeneous fractions show a general performance far greater than that of samples produced from mixed plastics. Separation of post-consumer mixed plastics (municipal waste) into four fractions—polyolefins (PO), PS, PVC, and PET—is commonly adequate.
