Plastics are a subset of materials known as Polymers. These are composed of large molecules formed by joining many smaller molecules together (monomers). Other kinds of polymers are fibres, elastomers, surface coating and biopolymers, such as cellulose, proteins and nucleic acids. Plastics owe their name to their ability to be shaped to form articles of practical value by various conversion and forming processes. These are some peculiar properties of plastics materials, which make them unique so that products can literally be tailor-made out of these materials.
In fact, plastics have permeated every facet of human life viz. agriculture and water consumption, buiilding construction, communication, small and bulk packaging, education, medicine, transportation, defence, consumer durables to name a few. One of the reasons for great popularity of plastics is due to tremendous range of properties exhibited by them because of their ease of processing. Hence, the demand for plastics has been increasing in modern living. Since last six decades, the Plastic Industry has grown world wide with present consumption of more than 130 MMTPA.
The Polymer/Plastic growth worldwide has been steady around 6% per annum which is much higher than the GDP growth rate of 3.3%. The higher growth sectors or demand drivers for plastic consumption are consumer and bulk packaging, plasticulture, building construction, electrical and electronics, automotive, consumer goods, medical, telecommunication, furniture and household applications. The output value of commodity, engineering and high performance polymers was US$115 billion, accounting for about 7% of total chemical output value globally.
In India, however, the consumption of major plastics is only 3% of global consumption i.e. 4 million tons annually. This is very low as compared to global levels.
Plastics have a very strong correlation with economic growth. The Central Statistical Organisation (CSO) and NCAER
