Sorting and Seperating Plants
Plastics have become indispensable in modern everyday life. Plastics are in packaging for food and drinks, car- or electronic-industries.
There are many different plastic typs in using, f.e. polyvinyl chloride (PVC), polystrene (PS), polypropylene (PP), polyethylene (PE), acrylonitrile/buta- diene/styrene (ABS), polycarbonate (PC) polyamide (PA), polyurethane (PUR), polyphenyloxide (PPO), poly- butylene terephthalate (PBT) and polymethyl methacrylate (PMMA).
A dominant type of plastic in excess of 50%, such as the polyolefins, PP and PE in household waste, does not exist. In addition there are products made of plastic mixtures (blends), parts with layers of paint and black bodies whose identification so far cause great difficulties. Another pro- blem in the sorting of waste from car and electronic waste is the variety of shapes and sizes.
