Industrial classification, textile, iron & steel, automobile, software industries, and industrial pollution
Manufacturing is the production of goods in large quantities using raw materials, machines, and labour. A strong manufacturing sector:
• Creates employment for millions (absorbs surplus agricultural labour)
• Earns foreign exchange through exports
• Reduces dependence on agriculture (diversifies economy)
• Promotes economic self-reliance
| Basis | Types | Examples |
|---|---|---|
| Size / Investment | Large-scale, Small-scale, Cottage | TATA Steel (large); handloom weaving (cottage) |
| Ownership | Public, Private, Joint, Cooperative | SAIL (public); Reliance (private); IFFCO (cooperative) |
| Raw material | Agro-based, Mineral-based, Forest-based, Marine-based | Cotton textile (agro); iron & steel (mineral) |
| Products | Basic/heavy (iron, steel, cement) or Consumer (bread, cycles, TV) | Bhilai Steel Plant (basic); HUL (consumer) |
India's textile industry is the largest industry in terms of employment (after agriculture) and second largest exporter of textiles globally.
Cotton textiles: Mumbai (Manchester of India), Ahmedabad (Boston of India), Surat, Kanpur
Silk textiles: Mysuru (Karnataka), Varanasi, Kanchipuram
Woollen textiles: Ludhiana, Amritsar, Srinagar
Challenges: Competition from cheap Chinese goods, power supply issues, outdated machinery in some units
Iron and steel is called a "key industry" because all other manufacturing depends on it. Steel is needed for machines, ships, buildings, railways, vehicles.
Location factors: Near coal fields (for coke), iron ore (raw material), water, and markets
Major plants:
• Bhilai (Chhattisgarh) — with Soviet cooperation; largest output
• Durgapur (West Bengal) — with British cooperation
• Rourkela (Odisha) — with German cooperation
• TISCO, Jamshedpur (Jharkhand) — oldest private steel plant (Tata, 1907)
• Bokaro (Jharkhand) — with Soviet cooperation
Information Technology became India's biggest export earner. "Silicon Valley" equivalents: Bengaluru (IT capital of India), Hyderabad (Cyberabad), Chennai, Pune, Mumbai, NCR Delhi.
India exports software and IT services to USA, Europe, Japan — earning over $200 billion per year. This sector employs millions of educated youth.
Air pollution: Smoke, fumes, particulates from factories → respiratory diseases
Water pollution: Untreated effluents dumped into rivers → kills aquatic life (Ganga, Yamuna severely polluted)
Land pollution: Industrial waste dumps contaminate soil → affects agriculture and drinking water
Noise pollution: Heavy machinery → hearing damage, stress
Solutions: Effluent treatment plants (ETPs), electrostatic precipitators (to reduce air pollution), using water recycling in factories, strict enforcement of pollution laws by CPCB and SPCBs
