Solid Waste Management – Rules and Practices in India

Solid Waste Management (UPSC Prelims + Mains)

Think of any Indian city after a festival, a weekly market day, or a big political rally. Streets look normal for a few hours, and then the real picture appears: mixed garbage, plastic cups, food waste, flower waste, wrappers, and dust. This "daily waste" may look small at the household level, but at the city level it becomes a major public health, environmental, and governance challenge.

Hydrological Restoration: The primary, secondary, and tertiary stages of a modern sewage treatment plant (STP) to eliminate waterborne pollutants.
Hydrological Restoration: The primary, secondary, and tertiary stages of a modern sewage treatment plant (STP) to eliminate waterborne pollutants.

Solid Waste Management (SWM) is not only about cleanliness. It is directly linked to urban floods (drains choked by waste), air pollution (open burning), water pollution (leachate into groundwater and lakes), disease burden (vectors like flies and rodents), climate change (methane from dumpsites), and dignity and safety of sanitation workers.


Why Solid Waste Management is in News

Solid waste management stays in news because India is tightening rules and pushing faster action on segregation, processing and remediation of old dumpsites. In January 2026, the Union Government notified the Solid Waste Management (SWM) Rules, 2026, which supersede the SWM Rules, 2016 and will come into full effect from 1 April 2026.

Another major focus is on "legacy waste" (old waste mountains). A national acceleration programme targets remediation of difficult dumpsites and prevention of new dumpsites, along with real-time monitoring and financial support to cities.

Swachh Survekshan rankings also keep SWM in the spotlight, as cities compete on door-to-door collection, segregation, processing, dumpsite remediation and "Waste to Wealth" outcomes.


📘 Solid Waste Management (SWM)

Solid Waste Management is the planned process of preventing waste generation, segregating waste at source, collecting and transporting it safely, recovering value through recycling/composting/processing, and disposing only the leftover rejects in an environmentally safe manner.

📘 Municipal Solid Waste (MSW)

Municipal solid waste is the everyday solid waste generated from households, shops, offices, markets, institutions and public spaces, typically managed by Urban Local Bodies (ULBs) and local authorities.


Meaning and Types of Solid Waste

1) By source

2) By nature (most important for processing)

📘 Waste Hierarchy

A priority order for waste management: Refuse > Reduce > Reuse > Repair > Recycle > Recover energy > Dispose. The higher steps save more resources and reduce pollution.

Stream-Based Disposal: Scientific source segregation of waste into biodegradable, non-biodegradable, and domestic hazardous categories.
Stream-Based Disposal: Scientific source segregation of waste into biodegradable, non-biodegradable, and domestic hazardous categories.

India's Waste Situation: Key Numbers and Trends

UPSC answers become stronger when you begin with one credible data point and then connect it to governance. A Lok Sabha reply (MoEF&CC) citing CPCB's annual report for 2020-21 states that India generated 160,038.9 tonnes per day (TPD) of solid waste; about 152,749.5 TPD was collected; about 79,956.3 TPD was segregated and treated; and about 29,427.2 TPD was landfilled.

The same reply highlights that under Swachh Bharat Mission, solid waste processing capacity increased from 26,000 TPD (2014) to 1,31,876 TPD (2022).

Table 1: Municipal solid waste generated in India (year-wise)

Year Quantity generated (tonnes per day)
2016-17 119,140.9
2017-18 43,298.3
2018-19 152,076.7
2019-20 150,761
2020-21 160,038.9

Source: Lok Sabha Unstarred Question No. 499 (MoEF&CC).

The same Lok Sabha reply reports that 34,69,780 tonnes of plastic waste was generated in 2019-20, and it also mentions policy actions like phasing out identified single-use plastic items from 1 July 2022 and increasing plastic carry bag thickness to 120 microns from 31.12.2022.

📘 Why India's waste composition matters

Indian municipal waste usually has a high biodegradable fraction and higher moisture than many developed countries. This makes segregation + composting/biomethanation very suitable, while "burning mixed waste" often becomes inefficient and polluting.


Why Poor Solid Waste Management is a Big Problem

1) Public health impacts

2) Environmental impacts

3) Climate impacts

4) Urban governance impacts

📘 Leachate

Leachate is the contaminated liquid formed when rainwater percolates through waste in dumpsites/landfills and dissolves pollutants. If not controlled, it enters soil and groundwater.

Urban Mining: The recovery of precious metals like gold and copper from electronic waste, a key pillar of the circular economy.

Legal and Policy Framework in India

1) Constitutional and governance base

2) Environment (Protection) Act, 1986

Most waste-related rules (including SWM Rules) are notified under the Environment (Protection) Act, 1986.

3) Major SWM rules: 2000 → 2016 → 2026

4) Related waste rules (important for UPSC linkage)

📘 Extended Producer Responsibility (EPR)

EPR means the producer/importer/brand owner is responsible for the environmentally sound management of a product even after it becomes waste (collection, recycling, safe disposal).


SWM Rules 2016 vs SWM Rules 2026: What UPSC Must Note

The SWM Rules, 2026 introduce clearer segregation streams, stronger compliance tools, and defined responsibilities for bulk waste generators.

Key highlights of SWM Rules, 2026 (as per PIB release)

Table 2: SWM Rules 2016 vs SWM Rules 2026 (exam-friendly comparison)

Topic SWM Rules, 2016 SWM Rules, 2026
Segregation at source 3 streams: biodegradable, non-biodegradable (dry), domestic hazardous 4 streams: wet, dry, sanitary, special care
Bulk waste generators Compliance obligations for bulk generators (on-site processing encouraged) Clear thresholds + EBWGR and certification framework
Compliance enforcement Authorisations, duties and monitoring through SPCBs/ULBs Environmental compensation (polluter pays), CPCB guidelines; SPCBs/PCCs levy
Approach Scientific management; reduce landfilling; improve processing Stronger circular economy orientation + EPR integration

📘 Bulk Waste Generator (BWG)

A bulk waste generator is a large entity that produces significant waste daily (such as large institutions, commercial complexes, RWAs). Under SWM Rules, 2026, BWGs are defined using thresholds like floor area, water use, or waste generated per day.


Institutional Setup: Who Does What?

1) MoHUA (Ministry of Housing and Urban Affairs)

2) MoEF&CC (Ministry of Environment, Forest and Climate Change)

3) CPCB and SPCBs/PCCs

4) Urban Local Bodies (ULBs) / Panchayats

📘 User Fee

User fee is the service charge paid by waste generators (households, shops, institutions) to support regular collection, transportation and processing of waste. A stable user-fee system improves municipal finances and accountability.


End-to-End Solid Waste Management System (Step-by-Step)

UPSC expects you to show the full chain: Generation → Segregation → Collection → Transportation → Processing/Recovery → Scientific Disposal. Weakness at any one stage collapses the system.

Clinical Containment: Standardized, color-coded biomedical waste disposal streams as per international biohazard protocols.
Clinical Containment: Standardized, color-coded biomedical waste disposal streams as per international biohazard protocols.

Step 1: Prevent and reduce waste (best step)

Step 2: Segregation at source (the "make or break" step)

If waste is mixed, it becomes dirty and low-value. Recycling and compost quality fall, and most of it ends up in dumpsites. That is why rules focus heavily on segregation.

Four-stream segregation (SWM Rules, 2026)

Stream Examples Best handling method
Wet waste Kitchen waste, peels, food leftovers, flowers Composting or bio-methanation
Dry waste Plastic, paper, metal, glass, wood, rubber MRF sorting → recycling
Sanitary waste Diapers, sanitary napkins, tampons, condoms Secure wrap and separate collection
Special care waste Paint cans, bulbs, mercury thermometers, medicines Authorised agencies/collection centres

📘 Material Recovery Facility (MRF)

An MRF is a facility where dry waste is received, sorted into different recyclable categories, stored, and sent to recyclers. MRFs are critical to build a circular economy and reduce landfill burden.

Step 3: Collection (primary collection)

Step 4: Transportation (secondary collection and transfer)

Step 5: Processing and recovery (turn waste into resources)

📘 Composting

Controlled decomposition of biodegradable waste to produce compost (soil conditioner). Works best when wet waste is clean and segregated.

📘 Bio-methanation

Anaerobic digestion of wet waste to produce biogas (energy) and digestate (can be used as manure after proper treatment). Suitable for markets, hotels, bulk generators and communities with consistent wet waste supply.

📘 Refuse-Derived Fuel (RDF)

Processed combustible fraction of dry waste (often plastics + paper + textiles) used as fuel in cement kilns or waste-to-energy plants. Quality depends on good segregation and moisture control.

Table 3: Major processing options (what to use and when)

Option Best suitable waste Main output Key advantages Key risks if poorly implemented
Home/community composting Clean wet waste Compost Low-cost, decentralised, reduces transport Odour and flies if mixed waste/poor aeration
Bio-methanation Wet waste with consistent supply Biogas + digestate Energy + manure, good for markets and bulk generators Needs skilled O&M; fails if feedstock is mixed
MRF + recycling Dry recyclables Recyclable materials Highest circular economy value, job creation Low-value plastics still remain; needs markets
Co-processing in cement kilns High-calorific dry waste/RDF Energy recovery in industrial process Reduces landfill, uses existing kilns Needs strict emission control and quality RDF
Waste-to-Energy (WtE) Dry combustible fraction (after segregation) Electricity/heat Reduces volume of waste Fails with wet mixed waste; emission concerns
Sanitary landfill Only rejects and inert residuals Safe disposal Controls leachate and landfill gas when designed well Land scarcity; long-term monitoring needed

Step 6: Scientific disposal (only for "rejects")

A modern SWM system does not "dump everything." The landfill should receive mainly inerts and processing rejects, not mixed raw waste.

📘 Sanitary Landfill

An engineered site with liners, leachate collection, gas management, and controlled covering, designed to prevent pollution. It is the last option in the waste hierarchy.


Legacy Waste and Dumpsite Remediation (Bio-mining/Bio-remediation)

Many Indian cities still carry the burden of old waste mountains created over decades. This "legacy waste" occupies valuable urban land, pollutes air and water, and creates fire hazards.

As per a January 2026 Lok Sabha reply via PIB, 2,488 dumpsites (with more than 1,000 tonnes of waste) and nearly 25 crore metric tonnes of legacy waste were identified for remediation. About 15.51 crore MT (62%) has been remediated and about 8,484.15 acres (56%) land has been reclaimed.

The same update describes the Dumpsite Remediation Acceleration Programme (DRAP) to fast-track remediation of 214 difficult dumpsites and prevent creation of new dumpsites by September 2026, along with monitoring systems and financial support.

What is bio-mining / bio-remediation in simple terms?

📘 Legacy Waste

Legacy waste is old waste accumulated in dumpsites over years. It is typically mixed, partially decomposed, and requires specialised remediation (biomining/bioremediation) before land can be reclaimed.

Case Studies and Best Practices (India)

In UPSC Mains, use one best practice as a short example and extract "transferable lessons." Do not write city stories without linking to policy learning.

Table 4: Best practices and what to learn

City/Model What they focused on Transferable learning for UPSC answers
Indore Strong door-to-door collection, segregation discipline, processing focus Behaviour + enforcement + systems outperform only "new plants" approach
Surat Cleanliness performance and consistent municipal service delivery Service reliability and accountability improve citizen compliance
Pune (SWaCH-type models) Integration of waste pickers for collection and segregation Inclusive SWM improves recovery and livelihoods
Ambikapur (decentralised approach) Decentralised processing and community participation Decentralisation reduces transport cost and landfill dependence
Alappuzha-type models Household/community composting to reduce wet waste load Wet waste management at source prevents dumpsite creation

Swachh Survekshan Awards 2023 highlighted that Surat joined Indore in the league of "Cleanest City," and the theme "Waste to Wealth" reflects the national emphasis on resource recovery.


Challenges in India's Solid Waste Management

1) Mixed waste due to poor segregation

2) Over-dependence on collection, under-investment in processing

3) Dumpsite mindset and land constraints

4) Weak enforcement and data gaps

5) Worker safety and dignity issues


Way Forward: Model Answers Need "Multi-Level Solutions"

A high-scoring UPSC answer shows solutions at five levels: household, community, local body, state/national policy, and market/industry.

1) Household and community level

2) ULB level (systems + accountability)

3) State and national level (policy + capacity)

4) Market and industry level (circular economy)

5) Technology level (use "appropriate technology")
