Facts that Matter
- Manufacturing means producing goods in large quantities after processing from raw materials to more valuable products. Manufacturing helps in transforming the raw materials into finished goods on a large scale and thus help earning profit as finished goods are costlier than raw materials. For instance, paper is manufactured from wood, sugar from sugarcane, iron and steel from iron ore, and aluminum from bauxite.
- Manufacturing sector is the backbone of economic development. The economic strength of a country is measured by the development of manufacturing industries in it.
- Manufacturing industries help in modernising agriculture, which forms the backbone of our economy. It also helps people by providing them jobs in secondary and tertiary sectors.
- Industrial development helps in reducing unemployment and poverty from our country. It also reduces regional disparities by establishing industries in tribal and backward areas.
- The location of industries are influenced by several factors such as availability of raw material, labour, capital, power and market, etc. It is difficult to find all these factors available at one place. Hence, manufacturing activity tends to locate at the most appropriate place where all the factors of industrial location are either available or can be arranged at lower cost.
- Industrialisation and urbanisation go hand in hand. Once industrial activities start, urbanisation also begins. Cities provide markets and services such as banking, insurance, transport, labour, consultants and financial advice, etc. to the industry.
Classification of Industries
- On the basis of source of raw materials used—Agro-based industries and mineralbased industries.
- According to their main role—Basic or key industries and consumer industries.
- On the basis of capital investment—Small-scale industries and large-scale industries.
- On the basis of ownership—Public sector industries, private sector industries, joint sector industries and cooperative sector industries.
- Based on the bulk and weight of raw material and finished goods—heavy industries and light industries.
- Textile Industry occupies unique position in the Indian economy.
- Earlier cotton textiles were produced with hand spinning and handloom weaving techniques. After the 18th century, powerlooms came into existence. In the 19th century textile mills were established. The first successful textile mill was established in Mumbai in 1854.
- Cotton textile industries in India are largely concentrated in and around Mumbai, Maharashtra and Gujarat.
- While spinning continues to be centralised in Maharashtra, Gujarat and Tamil Nadu, weaving is highly decentralised to provide scope for incorporating traditional skills and designs of weaving in cotton, silk, zari, embroidery, etc.
- India has world class production in spinning, but weaving supplies low quality of fabric as it cannot use much of the high quality yarn produced in the country.
- Today, there are nearly 1600 cotton and human made fibre textile mills in the country. About 80 per cent of these are in the private sector and the rest in the public and cooperative sectors.
- Cotton textile industry is facing several problems today due to irregular supply of electricity, old and outdated machinery, low output of labours and stiff competition with the synthetic fibre industry.
- The first Jute mill was set up near Kolkata in 1859 at Rishra. Today India is the largest producer of raw jute and jute goods. After partition in 1947, the jute mills remained in India but three-fourth of the jute producing area went to Bangladesh (previous East Pakistan). The jute industry supports 2.61 lakh workers directly and another 40 lakhs small and marginal farmers indirectly.
- Jute industry faces tough competition due to presence of synthetic substitutes in the international market and also from other competitors like Bangladesh, Brazil, Philippines, Egypt and Thailand.
- India is the second largest producer of sugar in the world and the first largest producer of gur and khandsari. There are over 460 sugar mills in the country spread over Uttar Pradesh, Bihar, Maharashtra, Karnataka, Tamil Nadu, Andhra Pradesh and Gujarat along with Punjab, Haryana and Madhya Pradesh.
- So far, north India is regarded as the main centre of sugar industry and half of the sugar mills of India are in Uttar Pradesh only. But in recent years, the mills have shifted to the southern and western states, especially in Maharashtra.
- Mineral-based Industries
- The iron and steel Industry is the base of all industries as it provides all types of machinery to run other industries.
- Steel is needed to manufacture a variety of engineering goods, construction material, defence, medical, telephonic, scientific equipment and a variety of consumer goods. Production and consumption of steel is considered as the index of a country’s development.
- Iron and steel is a heavy industry because all the raw materials as well as finished goods are heavy and bulky requiring heavy transportation costs. Three integrated steel plants were set up at Bhilai, Durgapur and Rourkela. Later two more steel plants, at Bokaro and Vishakhapatnam, were set up. Presently, there are 10 primary integrated and many mini steel plants in India.
- An integrated steel plant is large, handles everything in one complex—from putting together raw material to steel making, rolling and shaping.
- All public sector undertakings market their steel through Steel Authority of India Ltd. (SAIL) while TISCO markets its produce through Tata Steel. China is the largest producer of steel. It is also the world’s largest consumer of steel. In 2004, India was the largest exporter of steel. Chhotanagpur plateau region has the maximum concentration of iron and steel industries.
- Aluminium Smelting. Aluminium smelting is the second most important metallurgical industry in India. It is light, rust resistant, a good conductor of heat, malleable and becomes strong when it is mixed with other metals. Bauxite is the raw material used in the smelters in a very bulky, dark reddish coloured rock. It is used to manufacture aircraft, utensils and wires. It acts as a substitute of steel, copper, zinc and lead in a number of industries. There are 8 aluminum smelting plants in the country located in Orissa (Nalco and Balco), West Bengal, Kerala, Uttar Pradesh, Chhattisgarh.
- Nitrogenous Fertiliser Industry. India is the third largest producer of nitrogenous fertilisers. There are 57 fertiliser units manufacturing nitrogenous and complex nitrogenous fertilisers. Gujarat, Tamil Nadu, U.P., Punjab and Kerala are the main states.
- Other significant producers are Andhra Pradesh, Orissa, Rajasthan, Bihar, Maharashtra, Assam, West Bengal, Goa, Delhi, Madhya Pradesh and Karnataka.
- Cement Industry. Cement is used for construction activity such as building houses, factories, bridges, roads, airports, dams and for other commercial establishments. This industry requires bulky and heavy raw materials like limestone, silica, alumina and gypsum. Coal and electric power are needed apart from rail transportation. The first cement plant was set up in Chennai in 1904. After independence the industry expanded.
- Chemical Industries. The chemical industry in India is growing fast and contributes approximately 3 per cent of the GDP. It is the third largest industry in Asia and occupies the twelfth place in the world in term of its size. It comprises both large and small scale manufacturing units. Both inorganic and organic sectors have grown rapidly. Inorganic chemicals include sulphuric acid (used to manufacture fertilisers, synthetic fibres, plastics, adhesives, paints, dye-stuffs), nitric acid, alkalies, soda ash (used to make glass, soaps and detergents, paper) and caustic soda. Organic chemicals include petrochemicals, which are used for manufacturing of synthetic fibers, synthetic rubber, plastics, dye-stuffs, drugs and pharmaceuticals.
- Automobile Industry—Automobiles provide vehicles for quick transport of good services and passengers. This industry had developed rapidly in last 15 years. Today there are 15 manufacturers of passenger cars and multi-utility vehicles, 9 of commercial vehicles, 14 of the two and three-wheelers. The industry is located around Delhi, Gurgaon, Mumbai, Pune, Chennai, Kolkata, Lucknow, Indore, Hyderabad, Jamshedpur and Bangalore.
- Information Technology and Electronics Industry. The electronics industry includes a large range of products like transistor, television, telephones, cellular telecom, pagers, telephone exchange, radars, computers etc. Bangalore is considered as the electronic capital of India. Other important centres for electronic goods are Mumbai, Delhi, Hyderabad, Pune, Chennai, Kolkata, Lucknow and Coimbatore. The IT industry has employed a large number of population thus reducing the problem of unemployment.
- Undoubtedly, the rapid growth in industries has led to considerable economic growth but it has also led to the increase in pollution of land, water, air, noise eventually resulting in degradation of environment. Rapid industrialisation for rapid economic development has raised various serious problems.
- Hence, we should adopt ways to control environmental degradation. Water should be reused and recycled to minimise the use of water. It would be better if the factories make an arrangement for using their waste-water over and over again after scientifically treating it. Hot water and effluents should be treated before releasing them in rivers and ponds. Rainwater should be used to meet water requirements and harvesting of rain water should also be done.
Earplugs and earphones can be used to save oneself from the side effects of noise pollution. Generators should be fitted with silencers.
Oil or gas should be used in factories in place of coal in order to reduce smoke.
