3. Write the answers of 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?
Answer: Integrated Steel Plants are large plants, which handle everything in one complex – from putting together raw material to steel making, rolling, and shaping. Mini Steel Plants are smaller, have electric arc furnaces, use mainly steel scrap and sponge iron as inputs. They have re-rollers that use steel ingots as well. They produce mild and alloy steel of given specifications.
Problems of Steel Industry
- High costs and limited availability of coking coal
- Irregular supply of energy
- Lower productivity of labour
- Poor infrastructures like roads, transport and communication
Following are some recent developments that have led to a rise in the production capacity:
- Foreign direct investments (FDI) with the efforts of private entrepreneurs
- Improvement in production process by the use of newer technologies
- Allocation of fund and other resources for research and development
(ii) How do industries pollute the environment?
Answer: Industries are responsible for four types of pollution – air, water, land, and noise pollution. Following are the various reasons:
- Air pollution is caused by the presence of high proportion of sulphur dioxide and carbon monoxide and adversely affects human health, animals, plants, buildings, and the atmosphere as a whole.
- Thermal pollution of water occurs when hot water from factories and thermal plants are drained into rivers and ponds before cooling.
- Water pollution is caused by organic and inorganic industrial wastes and effluents discharged into rivers.
- Dumping of wastes like glass, harmful chemicals, industrial effluents, packaging, salts, and other garbage render the soil useless.
- Noise pollution is caused due to industrial and construction activities, factory equipment, generators, electric saws, drills, etc.
(iii) Discuss the steps to be taken to minimize environmental degradation by industry?
Answer: The steps to be taken to minimize environmental degradation by industry are:
- To control water pollution, industrial effluents need to be treated on primary, secondary, and tertiary levels.
- The use of water for processing should be minimized via reuse and recycling; rainwater can be harvested to meet water requirements.
- For the minimization of air pollution, smoke stacks should be fitted in factories with electrostatic precipitators, fabric filters, scrubbers and inertial separators.
- To control noise pollution, generators should be fitted with silencers and using earplugs and earphones besides other noise absorbing material.
