Q.1. How can the industrial pollution of fresh water be reduced? Explain various ways.    [CBSE 2019, 321273]
OR
How are industries responsible for polluting freshwater? Suggest any three measures to reduce the water pollution.    [CBSE (F) 2017]
Ans. 

  • Water pollution is caused by organic and inorganic industrial wastes and effluents discharged into rivers.  
  • The main culprits are paper, pulp, chemical, textile and dyeing, petroleum refineries, tanneries and electroplating industries that let out dyes, detergents, acids, salts and heavy metals like lead and mercury, pesticides, fertilizers, synthetic chemicals with carbon, plastics and rubber, etc., into the water bodies. 
  • Fly ash, phospo-gypsum and iron and steel slags are the major solid wastes in India.

Steps to minimize water pollution : 
(i) Minimising use of water for processing by reusing and recycling it in two or more successive stages. Harvesting of rainwater to meet water requirements.
(ii) Treating hot water and effluents before releasing them in rivers and ponds. Treatment of industrial effluents can be done in three phases (a) Primary treatment by mechanical means. This involves screening, grinding, flocculation and sedimentation, (b) Secondary treatment by biological process (c) Tertiary treatment by biological, chemical and physical processes. This involves recycling of wastewater.
(iii) Overdrawing of groundwater needs to be regulated legall

Q.2. 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?
OR
How are industries responsible for environmental degradation in India? Explain with Examples .   [BSE Delhi 2019 32/1/1]
Ans.
An integrated steel plant handles multiple activities within one complex— from raw materials, to steel making, rolling, shaping, among other which makes these steel plants to be huge in size. A mini steel plant is smaller as it produces mild and alloy steel of given requirements.
The problems faced by this industry are:
(a) The production costs are high due to high costs of basic materials such coke coal.
(b) In India, there is an irregular supply of electricity leading loss of time and added cost of generating electricity.
(c) Steel industries are located in regions with poor infrastructure which increases cost o f transportation and other utilities.
(d) Recent developments that have led to a rise in the production capacity of this industry is the entry of private players which have access to private capital investments and foreign direct investments which has allowed quicker expansion and increased efficiency through oversight.
(ii) How do industries pollute the environment?
Ans.
Industries pollute the environment through air, water, land and noise.
(i) Air pollution is caused by the release of oxides of carbon and nitrogen into the air by paper factories, brick kilns, etc. through burning of fossil fuels such as coal.
(ii) Water pollution is caused by the discharge of organic and inorganic industrial wastes into water bodies such as rivers by chemical industries, textile industries, etc.
(iii) Social erosion Industries such as tanneries, wood manufacturing, etc. lead to soil erosion or renders the soil infertile by dumping of waste products, cutting of trees, among other activities.
(iv) Noise pollution results from industrial and construction activities, whose high decibel level affect the nearby areas.
(iii) Discuss the steps to be taken to minimise environmental degradation by industry.
Ans. The steps needed to be taken to minimise environmental degradation are:
(i) Industrial wastes such as plastic, metal, etc. need to be recycled and re-used, thereby avoiding the need to dump in water bodies and landfills.
(ii) Industrial discharge needs to be treated on all three prior to flowing into sewage lines
(iii) Rainwater harvesting needs to be implemented to meet water requirements, and ground water usage should be regulated by law.
(iv) Smoke chimneys can be fitted with electrostatic precipitators, fabric filters, scrubbers and inertial separators to reduce the discharge of air pollutants.
(v) Noise pollution can be reduced by the use of silencers. Silent generators and redesigning of machinery can be done to reduce noise.

Ans.
After an industrial activity starts in a town, urbanisation follows. Industry provides employment to the people of the area. Population migrates from rural hinterlands to seek jobs, Housing and transport facilities are developed to accommodate these people. Other infrastructural developments take place leading to growth and development of the town into a city.
Sometimes, industries are located in or near the cities. Cities provide markets and services such as banking, insurance, transport, labour, consultants and financial advice, etc. to the industry. Thus, industrialisation and urbanisation go hand in hand.

Sugar industries are concentrated in the sugarcane producing areas:
(i) Sugarcane is a perishable good, it looses its sucrose content if delays in transportation occurs, so it needs to be in the nearby place.
(ii) Sugarcane is bulky and perishable, so transportation cost reduces.
(iii) Near it is to the production area, its production automatically increases.
(iv) The raw material used in the sugar mills, that sugarcane is bulky.
(v) In haulage, its sucrose content reduces.
Challenges: 
(i) Seasonal nature of the industry.
(ii) Old and inefficient methods of production.
(iii) Transport delays in reaching cane to the mills.
(iv) Need to maximise the use of bagasse

Q.26. “The economic strength of a country is measured by the development of manufacturing industries.” Support the statement with arguments.    [CBSE Delhi 2016]
Ans.
Manufacturing sector is considered as the backbone of economic development of our country due to following reasons:
(i) Manufacturing Industries not only help in modernising agriculture, which forms the backbone of our economy, they also reduce the heavy dependence of people on agricultural income by providing them jobs in secondary and tertiary sectors.
(ii) Industrial development eradicates unemployment and poverty from our country. This was the main philosophy behind public sector industries and joint sector ventures in India. It was also aimed at bringing down regional disparities by establishing industries in tribal and backward areas.
(iii) Export of manufactured goods expands trade and commerce, and brings in much needed foreign exchange.
(iv) Countries that transform their raw materials into a wide variety of finished goods of high value are prosperous. India’s prosperity lies in increasing and diversifying its manufacturing industries as quickly as possible.
