Industries are responsible for four kinds of pollution-air, water, land and noise pollution. Industrial pollution can be controlled by:
- Industries should be set up in distant areas away from human settlements.
- Minimise the use of water processing through reusing and recycling.
- Treating hot water and effluents before releasing them in rivers and ponds.
- Particulate matter in the air can be reduced by fitting smoke stacks to factories with electrostatic precipitators. Smoke can be reduced in factories by using gas or oil instead of coal.
- Machinery can be redesigned to increase energy efficiency and reduce noise.
