Plastics make up about 20% of the volume of landfills. There is, therefore, considerable interest in reusing or recycling these materials. To identify common plastics, a set of universal symbols is now used, five of which are illustrated here. They symbolize low- and high-density polyethylene, polyvinyl chloride, polypropylene, and polyethylene terephthalate.

(a) Tell which symbol belongs to which type of plastic.
(b) Find an item in the grocery or drug store made from each of these plastics. Properties of several plastics are listed in the table. Based on this information, describe how to separate samples of these plastics from one another.
