Diverse techniques have been developed for recycling commingled post-consumer waste (PCW). Usually, first the most readily identifiable constituents are removed, e.g., soft drink bottles (PET) and milk containers (HDPE). Next, the tailings, made of PE s (50-75 wt%), styrenics (about 25 wt% of PS, ABS and their blends), etc., are comminuted, washed, and segregated. The tailings can...

The majority of recycled plastic is PET (or PETE) or HDPE. PET is used for bottles of soda pop and other beverages. Recycled PET can be remolded for strapping materials and fibers for clothing or carpeting. HDPE is most commonly used for plastic milk jug containers. HDPE can be used as a plastic material in plastic pipe, bottle, and lumber applications. 

The manual sorting method is labor intensive and requires operators to monitor an assembly line and sort out clear plastic bottles (PET) from the milk containers (HDPE) and colored plastic containers (LDPE, PP, PVC). The automated method can employ one of several analytical techniques, including X-ray fluorescence, mass spectroscopy, Fourier Transform Near Infrared (FT-NIR) spectroscopy, Fourier Transform Medium Infrared (FTIR) spectroscopy, or tribo-electric analysis, on the recycled plastic materials. The state of Rhode Island has a single stream process to sort out the recycled materials with optical sorting technology. The recycled materials include cardboard, paper, glass, metal, and plastics (Rhode Island 2013).
