What is a chemical industry?

It is difficult to define chemical industry exactly because of the absolute necessity for chemicals in almost every manufacturing industry. However, chemical industry can be defined as one that consists of all companies engaged in converting raw materials obtained from the environment (air, water, petroleum, minerals, agricultural products etc) into basic chemicals or chemical intermediates as well as the companies that convert these intermediates into consumer products. It is central to modern world economy, converting raw materials into more than 70,000 different products. Polymers and plastics, especially polyethylene, propylene, polyvinyl chloride, polyethylene terephthalate, polystyrene and polycarbonate comprise about 80% of industry's output worldwide. Chemicals are used to make a wide variety of consumer goods, as well as thousands of products that are essential inputs to agriculture, manufacturing, construction and service industries. The chemical industry itself consumes about 26% of its own output. Major industrial customers include rubber and plastic companies, textiles, apparel, petroleum refining, pulp and paper and primary metals. Chemicals manufacture is nearly a $ 2 trillion global enterprise, and the EU and U.S. chemical companies are the 1 world's largest producers.
