Industries & Manufacturing
Industries in India
What you'll learn
- Industry — economic activity that converts raw materials into finished goods.
- Classification: primary, secondary, tertiary; large-scale vs small-scale; public vs private.
- Major industries: iron & steel, cotton textiles, information technology (IT), sugar.
- Industrial regions in India.
- Environmental impact of industries; sustainable development.
Key concepts
Classification of industries
| Basis | Types | Examples |
|---|---|---|
| Raw material | Agro-based, mineral-based, forest-based, marine-based | Sugar (agro); steel (mineral); paper (forest); fish processing (marine) |
| Size | Large-scale, medium, small-scale, cottage | TATA Steel (large); handloom (cottage) |
| Ownership | Public sector, private sector, joint sector, cooperative | SAIL (public); Reliance (private); Amul (cooperative) |
| Output | Heavy industry (steel, ship), light industry (electronics, toys) |
Major industries
1. Iron & Steel
- Raw materials: iron ore, coal, limestone, manganese.
- Located near raw materials OR near market (heavy transport cost).
- Key plants:
| Plant | Location | Setup |
|---|---|---|
| Jamshedpur (TISCO) | Jharkhand | 1907; first integrated steel plant; near Damodar coal + Odisha ore |
| Bhilai | Chhattisgarh | Soviet collaboration (1959); largest capacity |
| Rourkela | Odisha | German collaboration |
| Durgapur | West Bengal | British collaboration |
| Bokaro | Jharkhand | Soviet collaboration |
| Salem, Vishakhapatnam | TN, AP | South India plants |
2. Cotton Textile Industry
- Oldest and largest industry by employment after agriculture.
- Mumbai = "Manchester of India" — cotton + port + humid climate ideal.
- Also: Ahmedabad ("Manchester of India" too), Coimbatore, Chennai, Surat.
- Problems: competition from cheap synthetic fibres, power shortage.
3. Information Technology (IT) Industry
- India's fastest growing industry since 1990s.
- Bengaluru = "Silicon Valley of India" (40% of India's IT exports).
- Other hubs: Hyderabad, Chennai, Pune, Noida, Mumbai.
- India's IT sector earns ~$200 billion/year in exports.
- Needs: skilled manpower, internet connectivity, English proficiency.
4. Sugar Industry
- India = world's second largest producer of sugar (after Brazil).
- Mostly in Uttar Pradesh (north) and Maharashtra (south).
- Seasonal — crushes sugarcane only 4–5 months/year.
- Moving southward: Maharashtra cane has higher sucrose content.
Industrial regions
| Region | States | Key industries |
|---|---|---|
| Mumbai–Pune | Maharashtra | Cotton, engineering, chemicals, IT |
| Damodar Valley | Jharkhand, WB | Steel, coal, engineering |
| Hugli | West Bengal | Jute, paper, engineering |
| Bengaluru–Tamil Nadu | Karnataka, TN | IT, textiles, aerospace |
| Ahmedabad–Vadodara | Gujarat | Cotton, chemicals, petrochemicals |
| Chotanagpur | Jharkhand | Mining, metallurgy |
Environmental impact
- Air pollution: smoke from factories (SO₂, NO₂, particulates).
- Water pollution: effluents dumped into rivers (Ganga, Damodar).
- Land degradation: mining spoils, industrial waste.
- Noise pollution: machinery.
Sustainable solutions: effluent treatment plants, renewable energy in factories, ISO 14001 (environmental management), industrial estates with shared pollution control.
