? The term “plastics” includes materials composed of various
elements such as
carbon, hydrogen, oxygen, nitrogen, chlorine, and sulphur.
? Plastics are macromolecules, formed by polymerization and having
the ability to be shaped by the application of reasonable amount of
heat and pressure or any other form of forces.
? It is one of the few new chemical materials which pose
environmental problem.
? Polyethylene, polyvinyl chloride, polystyrene is largely used in the
manufacturing of plastics.

? Rapid population growth, urbanization and industrial growth have
led to severe problem of waste generation in urban centres.
? The waste quantities increased from 46 million tones in 2001 to
65 million tones in 2010.
? Report says that per capita per day production will increase to
0.7 kg in 2050.
? The characteristics of waste depends on various factors such as
food habits, traditions, lifestyle, climate etc.

? Plastics, depending on their physical properties, may be
classified as thermoplastic or thermosetting plastic materials.
? Thermoplastic materials can be formed into desired shapes
under heat and pressure and become solids on cooling. If they
are subjected to the same conditions of heat and pressure, they
can be remoulded.
? Thermosetting materials which once shaped cannot be
softened/ remoulded by the application of heat.
? Out of total uses of plastic, 80% are Thermoplastic and 20% are
Thermosetting.
