Answer: An integrated steel plant does all the activities involved in the value chain of steel manufacturing. Such plant begins from making steel from iron ore and end up in making steel products which are needed by the industry. Mini steel plants, on the other hand, buy finished steel from larger plants and produce various goods from that; like utensils, tools, etc.

Question 11: How do industries pollute the environment ?

Answer: Industries mainly pollute the air and water. Factories emit smoke which contains harmful gases. These gases cause air pollution. Factories produce effluents and release them into rivers and pond. Thus, water pollution is cause by factories. Many factories; like thermal power plant; also cause thermal pollution of water by releasing hot water into rivers and ponds. Additionally, factories also play a major role in soil pollution.

Question 12: Discuss the steps to be taken to minimize environmental degradation by industry ?

Answer: Preventing Environmental Degradation by Industry:

• Water should be reused and recycled in the industry. This will help in minimizing the use of freshwater.
