Waste plastics Direct recycling of waste plastics not always possible, e.g. waste plastics can be contaminated; moreover, they often mixed with different sorts of materials such as paper, glass, metal, biowaste, etc. Food and beverage packaging is a typical example when plastic attached to other materials (aluminum/polymer laminate). It is impossible to separate this laminate from paper at the recycling facility. Pyrolysis of some broadly used plastics gives the following yield of oil: Polyethylene, polypropylene, polystyrene: 70 -75% (weight) • Polyurethanes: 50-52 % (These values can change) Oil recovery from mixed plastics depends on the composition of the particular mixture.
