Chapter Overview

Production of goods in large quantities after processing raw materials into more valuable products is called manufacturing: paper from wood, sugar from sugarcane, steel from iron ore and aluminium from bauxite. Workers in steel factories, car plants, textile mills and bakeries are in the secondary sector.

The economic strength of a country is measured by the development of its manufacturing industries. The chapter explains why manufacturing matters, how industries are classified and located, the major industries of India, and how industrial pollution can be controlled for sustainable development.

Important Topics and Concepts

Importance of manufacturing

• Manufacturing helps modernise agriculture and reduces people’s heavy dependence on agricultural income by providing jobs in the secondary and tertiary sectors.
• Industrial development is a precondition for eradicating unemployment and poverty; this was the philosophy behind public sector and joint sector industries, which also aimed to reduce regional disparities by setting up industries in tribal and backward areas.
• Export of manufactured goods expands trade and brings in foreign exchange.
• Countries that turn raw materials into a wide variety of higher-value finished goods are prosperous.

Agriculture and industry go hand in hand

• Agro-industries have boosted agricultural productivity.
• They depend on agriculture for raw materials and sell irrigation pumps, fertilisers, insecticides, pesticides, PVC pipes, machines and tools to farmers.
• In the age of globalisation, Indian industry must be efficient and competitive, with goods matching international quality.

Classification of industries

• Source of raw materials: agro-based (cotton, woollen, jute, silk textiles, rubber, sugar, tea, coffee, edible oil) and mineral-based (iron and steel, cement, aluminium, machine tools, petrochemicals).
• Main role: basic or key industries supply products as raw materials for other goods (iron and steel, copper and aluminium smelting); consumer industries produce goods for direct use (sugar, toothpaste, paper, sewing machines, fans).
• Capital investment: a small scale industry is defined by the maximum investment allowed on its assets, currently rupees one crore.
• Ownership: public sector (BHEL, SAIL), private sector (TISCO, Bajaj Auto, Dabur), joint sector (Oil India Ltd), and cooperative sector (sugar industry in Maharashtra, coir industry in Kerala).
• Bulk and weight: heavy industries (iron and steel) and light industries (electrical goods).

Textile industry

• Contributes significantly to industrial production, employment and foreign exchange.
• It is the only industry in India that is self-reliant and complete in the value chain, from raw material to highest value-added products.

Cotton textiles

• Ancient India produced cotton textiles by hand spinning and handloom weaving; power looms came after the 18th century; traditional industries suffered under colonial rule.
• The first successful textile mill was set up in Mumbai in 1854.
• Early mills were concentrated in the cotton belt of Maharashtra and Gujarat because of raw cotton, market, transport and port facilities, labour and moist climate.
• The industry supports farmers, boll pluckers and workers in ginning, spinning, weaving, dyeing, designing, packaging and tailoring, and creates demand for chemicals, dyes, packaging and engineering.
• Spinning is centralised in Maharashtra, Gujarat and Tamil Nadu; weaving is decentralised to use traditional skills and designs.
• India has world-class spinning, but weaving produces lower-quality fabric as it cannot use much of the high-quality yarn. Handspun khadi gives large-scale employment in homes.

Jute textiles

• India is the largest producer of raw jute and jute goods and the second largest exporter after Bangladesh.
• Most mills are in West Bengal along the banks of the Hugli river. The first jute mill was set up at Rishra near Kolkata in 1855.
• After Partition in 1947, the mills stayed in India but three-fourths of jute-producing area went to Bangladesh.
• Location factors in the Hugli basin: nearness to jute-growing areas, cheap water transport with good rail, road and waterway links, abundant water for processing, cheap labour from West Bengal, Bihar, Odisha and UP, and Kolkata’s banking, insurance and port facilities.

Sugar industry

• India is the second largest producer of sugar in the world and first in gur and khandsari.
• Sugarcane is bulky and loses sucrose in haulage, so mills are located near cane areas.
• Mills are in UP, Bihar, Maharashtra, Karnataka, Tamil Nadu, Andhra Pradesh, Gujarat, Punjab, Haryana and Madhya Pradesh; 60 per cent are in UP and Bihar.
• It is seasonal, so it suits the cooperative sector.
• Mills are shifting to southern and western states, especially Maharashtra, because cane there has higher sucrose content, the cooler climate gives a longer crushing season and cooperatives are more successful.

Iron and steel industry

• The basic industry, as all heavy, medium and light industries depend on it for machinery; steel is needed for engineering goods, construction, defence, medical, telephonic and scientific equipment and consumer goods.
• Production and consumption of steel is regarded as an index of a country’s development.
• It is a heavy industry because raw materials and finished goods are heavy and bulky.
• Iron ore, coking coal and limestone are needed in the ratio of about 4 : 2 : 1; manganese hardens steel.
• The Chotanagpur plateau has the maximum concentration because of low-cost iron ore, high-grade raw materials nearby, cheap labour and a large home market.

Aluminium smelting

• Second most important metallurgical industry in India.
• Aluminium is light, corrosion-resistant, a good conductor of heat, malleable and strong when alloyed; used for aircraft, utensils and wires, and as a substitute for steel, copper, zinc and lead.
• Plants are in Odisha, West Bengal, Kerala, Uttar Pradesh, Chhattisgarh, Maharashtra and Tamil Nadu.
• Bauxite is a bulky, dark reddish rock. Regular electricity supply and an assured source of raw material at minimum cost are the two prime location factors.

Chemical and fertiliser industries

• The chemical industry is fast growing and diversified, with large and small units.
• Inorganic chemicals: sulphuric acid (fertilisers, synthetic fibres, plastics, adhesives, paints, dyes), nitric acid, alkalies, soda ash (glass, soaps, detergents, paper) and caustic soda; widely spread.
• Organic chemicals: petrochemicals for synthetic fibres, rubber, plastics, dyes, drugs and pharmaceuticals; located near oil refineries or petrochemical plants.
• The chemical industry is its own largest consumer.
• Fertilisers: nitrogenous (mainly urea), phosphatic, ammonium phosphate (DAP) and complex NPK fertilisers. Potash is entirely imported. After the Green Revolution the industry spread; Gujarat, Tamil Nadu, Uttar Pradesh, Punjab and Kerala produce half of the fertilisers.

Cement industry

• Essential for building houses, factories, bridges, roads, airports and dams.
• Needs bulky raw materials like limestone, silica and gypsum, plus coal, electric power and rail transport.
• The first cement plant was set up in Chennai in 1904; the industry expanded after Independence.
• Plants in Gujarat have access to markets in the Gulf countries.

Automobile industry

• Provides vehicles for quick transport of goods, services and passengers: trucks, buses, cars, motorcycles, scooters, three-wheelers and multi-utility vehicles.
• After liberalisation, new models stimulated demand and healthy growth.
• Located around Delhi, Gurugram, Mumbai, Pune, Chennai, Kolkata, Lucknow, Indore, Hyderabad, Jamshedpur and Bengaluru.

Information technology and electronics

• Covers transistor sets, televisions, telephones, cellular telecom, telephone exchanges, radars and computers.
• Bengaluru has emerged as the electronic capital of India; other centres are Mumbai, Delhi, Hyderabad, Pune, Chennai, Kolkata, Lucknow and Coimbatore.
• Major concentration at Bengaluru, Noida, Mumbai, Chennai, Hyderabad and Pune.
• Its major impact has been employment generation; growth in hardware and software is key to its success.

Industrial pollution and environmental degradation

• Air pollution: high proportion of undesirable gases like sulphur dioxide and carbon monoxide, and particulate matter (dust, sprays, mist, smoke) from chemical and paper factories, brick kilns, refineries, smelting plants and fossil fuel burning. Toxic gas leaks, such as the Bhopal gas tragedy, have long-term effects.
• Water pollution: organic and inorganic wastes and effluents from paper, pulp, chemical, textile, dyeing, refineries, tanneries and electroplating industries, releasing dyes, detergents, acids, salts and heavy metals like lead and mercury. Fly ash, phospho-gypsum and iron and steel slags are major solid wastes.
• Thermal pollution: hot water from factories and thermal plants drained into rivers before cooling, harming aquatic life. Nuclear wastes cause cancers, birth defects and miscarriages.
• Land pollution: dumping of glass, chemicals, effluents, packaging, salts and garbage makes soil useless; pollutants seep into groundwater.
• Noise pollution: machinery, generators, saws and drills cause irritation, stress, hearing impairment, higher heart rate and blood pressure.

Control of environmental degradation

• Every litre of industrial waste water pollutes eight times the quantity of freshwater.
• Reduce water pollution by reusing and recycling water in successive stages, harvesting rainwater, and treating hot water and effluents before release.
• Effluent treatment: primary (mechanical: screening, grinding, flocculation, sedimentation), secondary (biological) and tertiary (biological, chemical and physical, including recycling of wastewater).
• Regulate overdrawing of groundwater by industry legally.
• Reduce particulate matter with electrostatic precipitators, fabric filters, scrubbers and inertial separators on smoke stacks; use oil or gas instead of coal.
• Fit generators with silencers, redesign machinery for energy efficiency and less noise, use noise-absorbing materials and earplugs.

NTPC shows the way

• NTPC, a major power corporation, has ISO 14001 certification for its Environment Management System.
• It preserves natural resources through optimum use of equipment with the latest techniques and upgrading.
• It minimises waste by maximising ash utilisation.
• It provides green belts for ecological balance and promotes afforestation.
• It reduces pollution through ash pond management, ash water recycling and liquid waste management, and runs ecological monitoring and online databases for its power stations.
