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

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

Integrated steel plants Mini steel plants
1. These are plants where all the pro¬cesses are carried out in one complex, from handling of raw material, steel making, rolling and shaping of the steel. 1. These are decent¬ralized secondary units which speci¬alize in one or two processes.
2. These plants need large investments. 2. These plants need less investments.
3. These fulfil local as well as international demands. 3. These fulfil local demands.
4. There are 10 inte¬grated steel plants in India. 4. There are more thar 400 mini steel plants in India.

(i) Capital:
Iron and steel industry requires large capital investment which a developing country like India cannot afford.

(ii) Modernisation:
Public sector plants are more than 35 years old. Their machines have become obsolete and so their productivity is very low as compared to
developed countries.

(iii) Low productivity :
The per capita labour productivity in India is at 90-100 tonnes Which is one of the lowest in the world.

(iv) Low potential utilization :
The potential utilization in iron and steel industry is very low. Rarely the potential utilization exceeds 80%.

Steps taken by the government :

  1. Government is following the steps of liberalization and globalization.
  2. Foreign direct investment is being encouraged in this sector.
  3. How do industries pollute the environment ?

Answer:
Industries pollute the environment by the following ways :
(i) Air pollution :
The smoke emitted by the industries pollute air. Air pollution is caused by the presence of higher proportion of undesirable gases, such as carbon monoxide, sulphur dioxide Air borne particulate materials consist of both solid and liquid particles. Human made sources of pollutants are normally industrial and solid wastes. Air pollution affects human health, animals, plants, materials and the atmosphere.

(ii) Water pollution:
Most important water pollutants are the industrial effluents that are discharged in the rivers. They are both organic and inorgaitic. Coal, dyes, soaps, pesticides, fertilizers and rubber are some common pollutants of water.

(iii) Thermal Pollution :
Whfen hot water from factories and thermal plants is drained into rivers and ponds before cooling then thermal pollution of water occurs.

RBSE Class 10 Social Science Geography Solutions Geography Chapter 6 Manufacturing Industries

(iv) Noise pollution :
It arises primarily from industry’ and means of transport. Industrial noise, particularly, from mechanical saws and pneumatic drills, is unbearable and is a nuisance to the public. Noise causes impairment of hearing.

(iii) Discuss the steps to be taken to minimise environmental degradation by industry.
Answer:
Steps to minimize industrial degradation :

  1. Minimising uge of water for processing by reusing and recycling it in two or more successive stages.
  2. Harvesting of rainwater to meet water requirements.
  3. Treating hot water and effluents before releasing them in rivers and ponds. Treatments of industrial effluents can be done in three phases.
  4. Overdrawing of ground water reserves by industry where there is a threat to ground water and resources should be regulated legally.
  5. Smoke can be reduced by using oil or gas instead of coal in factories.
  6. To minimize noise pollution, machinery and equipment can be used and generators should be fitted with silencers.
