India's first waste-burning power plant, at Timarpur in 1987, ran for just 21 days: the rubbish was too wet.

##### Where it comes from

Chart: Map of where it comes from

Waste-to-energy recovers the chemical energy in rubbish, residues and spent oil as heat, power or reusable products. Europe had 499 plants treating 101 Mt of residual waste in 2023.

##### Three things to know

1. Indian mixed waste holds about 1,411-2,150 kcal/kg, often below the roughly 1,800 needed to burn without support fuel.
2. Corrosive flue gas caps waste boiler steam at about 400 C, so power-only plants manage about 20% efficiency at most.
3. India's 2026 waste rules require cement plants to raise refuse-derived fuel to 15% of solid fuel within six years.

##### The journey

1. 1 **Waste**Rubbish, crop residue or used oil
2. 2 **Sort and prepare**Segregate, dry, shred into refuse-derived fuel
3. 3 **Burn or refine**Incinerator, cement kiln, gasifier or re-refinery
4. 4 **Clean up**Gas cleaning traps acid, metals and ash
5. 5 **Output**Power, district heat, kiln fuel, base oil
