Question

Ghissu Editorial · Accepted Answer

The world iron and steel industry has shifted from coalfields to coastal break-of-bulk sites, to market-based mini-mills and finally to Asia as technology, costs and markets changed. China now makes over half the world's crude steel, and India became the second largest producer in 2018.

**Introduction**

Iron and steel is a weight-losing industry, so it locates where coal, ore and markets meet most cheaply. As that point moved, the industry shifted from Europe and North America to coasts and then to Asia, where China makes over half the world's crude steel.

**Phases of the Changing Pattern**

SKETCH: comparison | Old vs New Steel Geography
a: Old pattern
b: New pattern
- Coalfield sites :: Coastal and market sites
- Atlantic world :: Asia-Pacific
- Coking coal :: Scrap, gas, hydrogen
- Giant integrated works :: Mini-mills and DRI

1. **Coalfield phase**: When steel needed several tonnes of coal per tonne, plants clustered in the Ruhr, Pittsburgh, Sheffield and the Donbas.
2. **Break-of-bulk coasts**: Imported Pilbara and Carajas ore favoured port plants such as Chiba, Pohang (1973), IJmuiden and Taranto.
3. **Mini-mills**: Scrap-based electric arc furnaces, led by Nucor, let smaller plants locate near cities and their scrap supply.
4. **Asian ascent**: Cheap labour, state support and construction booms made China dominant, and India became second largest in 2018.

**Forces Behind the Shift**

1. **Technology**: Lower coke rates and new furnaces weakened the coalfield pull, while gas-based direct reduction drew plants to the Gulf.
2. **Costs and markets**: High wages, ageing plants and saturated demand created the US Rust Belt and shrank European output as demand grew in Asia.
3. **Environment and policy**: The EU's Carbon Border Adjustment Mechanism is steering investment to hydrogen steel, as in Sweden's HYBRIT project, which delivered fossil-free steel in 2021.

**Conclusion**

Steel's map has moved from raw material to coast, market and now low-carbon energy, and from the Atlantic world to Asia. India, with ore, a growing market and green hydrogen ambitions, is well placed to lead this cleaner phase.
