3. Industries and Transport:
From cloth mills, lather factories, petro-chemical industries and refineries to metal industries- all use numerous fuels for power generation and chemical products for processing their product and improve the equality and simultaneously produce pollution. Now-a-days chemical effluent treatment plants use chemicals to control or neutralist he hazardous impact of pollutants produced by the industries. Aviation and shipping industries generate power through power plants which burn fuels. Petrol and diesel emit out green house gases dangerous for the survival on earth which damage the ozone layer that protects us from UV rays. As a result global warming has taken place which is a destroyer of the planet earth. But again Chemistry paves the way with bio-fuels.
