3. Write the answers to the following questions in 120 words.

(i) How are integrated steel plants different from mini steel plants? What problems does the industry face? What recent developments have led to a rise in the production capacity?

Solution

An integrated steel plant is a large unit. It handles everything in one complex. These collect raw materials to make steel, by rolling and shaping. Mini steel plants are smaller units. These have electric furnaces. These use steel scrap and sponge iron. These have re-rollers that use steel ingots as well. These produce mica and alloy steel.

Problems faced by these Industries:
(i) High cost of production.
(ii) Limited availability of coking coal.
(iii) Lower productivity of labour.
(d) Irregular supply of energy.
(e) Poor infrastructure.

Some recent developments have increased the production capacity of this industry such as:
(a) Liberalisation
(b) Foreign direct investment
(c) Private ownership
(d) Resources for research and development have been increased

(ii) How do industries pollute the environment?

Solution

Careful planning of industries, better design equipment and better operation of the equipments can prevent pollution to a great extent. Some measures to control industrial pollution are:

(i) Restricting use of fossil fuels can reduce smoke. Air pollution can be redued by reduction of particulate matter, aerosol emission in the air by fitting smoke stacks to factories with electrostatic precipitators, fabric filters, scrubbers and inertial separators.

(ii) Water pollution can be controlled by minimising use of freshwater by reusing and recycling. Treatment of hot water effluents before releasing them in rivers and other water bodies. These include mechanical, biological, chemical and physical processes.

(iii) Land pollution can be controlled by collection of wastes, dumping and disposing the wastes in filling areas and recycling the wastes.

(iv) Machinery and equipment and generators can be fitted with silencers or redesigned to make them energy efficient and to reduce noise.
