Urban Waste Disposal in India: Rules and the Landfill Problem

1.1 Why does waste outpace disposal?

Indian cities now produce nearly 1.62 lakh tonnes of municipal solid waste every day.

Government estimates say it may reach 165 million tonnes a year by 2030 and 436 million by 2050. Collection and treatment have to grow just as fast.

1.2 What happens to old waste?

Much of it sits in open dumpsites. About 2,479 such sites were identified.

They hold an estimated 25 crore tonnes of old waste on nearly 15,000 acres of land.

1.3 Why are dumpsites a problem?

Rain washes pollutants into groundwater and soil. Rotting waste also releases methane, a strong greenhouse gas.

Dumpsites also catch fire and breed disease carriers.

2.1 Which rules govern waste now?

The Solid Waste Management Rules, 2026 were notified on 27 January 2026. They apply from 1 April 2026.

They replace the Solid Waste Management Rules, 2016. Many older exam questions still use the 2016 version.

2.2 How many streams must be kept apart?

Generators must keep waste in four streams at source: wet, dry, sanitary and special care waste.

The 2016 Rules named three streams: bio-degradable, non-biodegradable and domestic hazardous waste. The 2026 Rules name four.

2.3 What goes in each stream?

Wet waste is kitchen, food, vegetable, meat and flower waste. Dry waste is everything else that is not wet, sanitary or special care.

Sanitary waste covers used diapers, sanitary towels, tampons and similar items. Special care waste covers items such as paint drums, expired medicines, tube lights, batteries and used needles.

2.4 Who counts as a bulk generator?

Under 2026, a bulk generator has any one of three features. The first is a floor area of 20,000 sq m or more. The second is 40,000 litres of water used a day. The third is 100 kg of waste made a day.

Under 2016 the test was only an average of more than 100 kg of waste a day.

The last two rows did not change.

2.5 What new duty falls on bulk generators?

They must register on an online portal. They must also meet Extended Bulk Waste Generator Responsibility.

That means processing their wet waste and sending dry, special care and sanitary waste for sound management.

3.1 What are the main disposal methods?

Cities use composting, biogas, burning, co-processing and, last, landfill. Each suits a different kind of waste.

• Composting: microbes break down wet waste into manure.
• Anaerobic digestion: microbes break down wet waste without air and give biogas.
• Incineration: waste is burned at high temperature.
• Co-processing: high-calorific waste is burned as fuel in cement kilns or power plants.

3.2 Which waste may go to a sanitary landfill?

Only waste that cannot be treated any other way should go there.

The 2026 Rules say no wet waste and no construction and demolition waste may go to a sanitary landfill.

3.3 Where can a landfill be built?

A landfill site must be at least 100 m from a river and 200 m from a pond.

No landfill is allowed in flood plains, wetlands and similar sensitive places. In hilly areas the landfill is built in the plains within 25 km.

3.4 Why is burning not a general answer?

Incineration works for waste with high heat value. Wet kitchen waste burns poorly.

The 2016 Rules asked that high-calorific waste go to cement kilns or power plants instead of a landfill.

4.1 Why does a landfill make gas?

Buried wet waste rots without air. This slow breakdown makes methane.

Methane is also the main part of biogas. A landfill that lets it escape wastes a fuel and heats the air.

4.2 What do the rules require?

The 2026 Rules say a landfill needs a gas control system, including a collection system.

The purpose is to reduce odour and stop gas from moving off the site.

4.3 How is a biogas plant different?

A biogas plant breaks down wet waste on purpose in a closed tank. The gas is caught and used.

The Rules call this biomethanation. It gives biogas, which has methane in it.

5.1 What was Ghazipur meant to be?

Ghazipur landfill in east Delhi has been working since 1984. It covers about 70 acres.

It was meant to stop growing at about 65 feet. It reached about 165 feet.

5.2 What happened on 1 September 2017?

Part of the mound collapsed. Waste swept vehicles into a nearby canal. Two people died.

Some experts blamed heavy monsoon rain. The collapse showed the risk of very tall waste heaps.

5.3 How is it being cleared?

Biomining is the main tool. It separates old waste into fine soil, stones, metals, plastic and cloth.

Capacity rose from 7,000 to 12,000 tonnes a day by 31 July. About 20 acres are reclaimed and about 50 acres remain.

5.4 Is it on schedule?

Phase 1 targeted 30 lakh tonnes and processed 13.90 lakh tonnes. The target to clear the rest is December 2027.

Meanwhile 2,400 to 2,500 tonnes of fresh waste arrive every day. That slows the clean-up.

6.1 What is the national plan for old dumpsites?

The Dumpsite Remediation Acceleration Plan, or DRAP, began in November 2025. Its goal is Lakshya Zero Dumpsites by October 2026.

The Centre gives Rs 550 for each tonne of legacy waste processed. About 1,138 dumpsites in 1,048 cities have been fully cleared.

6.2 Which sites matter most?

A set of 214 high-impact sites holds about 80% of the remaining old waste.

The plan stresses stopping new dumpsites. All fresh waste should be processed in a scientific way.

6.3 What do success stories look like?

Gorakhpur cleared a 40-acre site by biomining 400 tonnes a day. It made refuse-derived fuel, black soil and recyclables.

The refuse-derived fuel went to cement plants. The cleared land now holds the Rapti Eco Park.

6.4 What happened at the other sites?

Bhalswa in Delhi covers about 70 acres. Biomining there began in July 2022 and had cleared 99.07 lakh tonnes by 31 July 2026.

Nagpur’s Bhandewadi site treated over 10 lakh tonnes and is now an integrated waste facility. Raichur reclaimed 22 acres and grew a Miyawaki forest.

6.5 Which mission supports the work?

The Swachh Bharat Mission-Urban began in October 2014. Its second phase began in October 2021.

The clean-up of legacy dumpsites sits under this mission.

7.1 Which traps appear in exams?

Version trap: Old questions use the 2016 Rules. The 2026 Rules now apply, so check which year a question names.

Stream trap: 2016 had three streams. 2026 has four.

Bulk trap: 2016 used only 100 kg a day. 2026 also uses floor area and water use.

Landfill trap: No wet waste goes to a sanitary landfill.
