Transforming a waste-ridden urban India

Context
In this article, the author discusses the growing crisis of solid waste management in urban India and argues for a decisive shift from a linear model of waste disposal to a circular economy approach. Using India’s urbanisation trends, climate commitments, and policy initiatives, the article highlights how waste—if managed scientifically—can be converted into a resource, contributing to cleaner cities, public health, climate mitigation, and resource security.
Detailed Analysis
1. Urbanisation and the Waste Challenge
- Rapid expansion of cities and towns in India is inevitable, but the nature of urban growth has led to waste-ridden and polluted cities.
- Indian cities fail to meet global standards of clean and healthy living environments.
- Regions like the National Capital Region (NCR) are among the most polluted globally, with waste mismanagement worsening air, land, and water pollution.
- Despite judicial interventions and regulatory efforts, outcomes remain limited, and citizen grievances are rising.
2. Scale of the Problem
- Urban India is projected to generate 165 million tonnes of waste annually by 2030, rising to 436 million tonnes by 2050 as the urban population grows.
- Waste-related emissions could exceed 41 million tonnes of greenhouse gases annually.
- Without effective solutions, waste threatens public health, economic productivity, and overall quality of urban life.
- The goal of Garbage Free Cities (GFC) by 2026 is therefore a necessity, not merely an aesthetic ambition.
3. Circular Economy as the Way Forward
- The article stresses the need to move away from a linear ‘use-and-dispose’ model to a circular mode of waste management, where waste is treated as a resource.
- Circularity focuses on minimising waste generation, maximising reuse and recycling, and recovering energy and materials.
- International climate platforms such as COP30 and initiatives like Mission LiFE reinforce circularity as central to sustainable urban development.
4. Managing Organic and Plastic Waste
- Over half of municipal waste is organic, which can be effectively managed through composting and bio-methanation.
- Compressed Biogas (CBG) plants offer dual benefits: waste reduction and clean energy generation.
- However, plastic waste, which dominates dry waste streams, poses the toughest challenge due to its non-biodegradable nature and threat to ecosystems and human health.
- Effective source segregation at the household level is critical for successful recycling and material recovery.
5. Construction and Demolition (C&D) Waste
- India generates about 12 million tonnes of C&D waste annually, making it a major urban pollutant.
- Unauthorised dumping on roadsides, open lands, and city outskirts is common due to weak enforcement.
- Though C&D waste can be reused as cost-effective raw material, mixing with unsegregated household waste reduces recycling efficiency.
- Recycling capacity exists but is insufficient compared to the scale of waste generation.
6. Regulatory Framework and Implementation Gaps
- The Construction and Demolition Waste Management Rules, 2016 aim to regulate waste generation and levy charges on large generators.
- Updated C&D Waste Management Rules, 2025 (effective April 2026) seek stronger compliance.
- However, challenges remain in identification, tracking, accountability, and enforcement, particularly due to weak inter-departmental coordination.
7. Wastewater and Water Security
- Wastewater management is closely linked to urban water security.
- Reuse of treated wastewater for agriculture, horticulture, and industrial purposes can reduce freshwater stress.
- Missions like AMRUT and Swachh Bharat Mission (SBM) recognise the role of sewage and faecal sludge management in achieving sustainable cities.
- Recycling and reuse of wastewater are essential to meet rising urban water demand.
8. Hurdles to Achieving Circularity
- Circularity involves multiple actors, making coordination complex.
- Challenges include:
- Inefficient segregation and collection systems
- Infrastructure and monitoring shortfalls
- Poor quality and marketability of recycled products
- Limited extension of Extended Producer Responsibility (EPR) to all dry waste categories
- Lack of incentives, weak penalties, and low stakeholder awareness further slow progress.
9. Emerging Positive Trends
- National and regional deliberations, such as urban conclaves and the Cities Coalition for Circularity (C-3), show growing policy focus.
- Knowledge-sharing among cities and institutions is being encouraged.
- There is recognition that citizens must see economic and social value in circular practices to actively participate.
Suggestions of the Author
- Ensure strict enforcement of waste management rules, especially for construction and demolition waste.
- Strengthen source segregation and decentralised waste processing.
- Expand EPR frameworks to cover all dry waste streams.
- Promote reuse and recycling of wastewater to enhance urban water security.
- Improve inter-departmental coordination, incentives, and penalty mechanisms.
- Encourage citizen participation by demonstrating tangible benefits of circularity.
- Use technology and private sector participation to scale recycling and energy recovery.
UPSC Mains Question
“Urban waste management in India requires a shift from a linear disposal model to a circular economy approach.” Examine the challenges and opportunities in implementing circular waste management in Indian cities.
Recasting sanitation with urban-rural partnerships
Context
In this article, the authors examine how India’s sanitation journey under the Swachh Bharat Mission (SBM) must evolve beyond toilet construction to address the critical challenge of faecal sludge and septage management (FSSM). They argue that urban–rural partnerships offer a practical and scalable solution to bridge sanitation gaps, especially in peri-urban and rural areas, by leveraging existing urban treatment infrastructure.
Detailed Analysis
1. From Toilet Access to Sanitation Sustainability
- The launch of Swachh Bharat Mission (Clean India Mission) in 2014 aimed to ensure universal toilet access.
- In a decade, over 12 crore toilets were constructed, and rural India largely achieved Open Defecation Free (ODF) status.
- This marked a major public health and dignity milestone, particularly for women and vulnerable groups.
- However, toilets are only the starting point; sustainable sanitation depends on safe management of waste generated.
2. The Hidden Challenge of Faecal Sludge
- In rural areas, septic tanks and pits are the dominant sanitation systems.
- These systems fill up over time and require regular desludging, failing which sanitation gains are reversed.
- Unsafe or irregular desludging, often done by informal operators, poses health and environmental risks.
- This challenge defines the transition from SBM Phase I to SBM-G (Grameen) Phase II, which focuses on ODF Plus outcomes.
3. Gaps in Rural Sanitation Infrastructure
- Rural and peri-urban areas often lack:
- Safe collection systems
- Transport mechanisms
- Treatment facilities for faecal sludge
- As a result, sludge is frequently dumped untreated, undermining ODF achievements.
- Faecal sludge management remains one of the weakest links in India’s sanitation chain.
4. Maharashtra’s Innovative Approach
- Maharashtra has taken the lead by experimenting with innovative sanitation models.
- The State has invested in over 200 faecal sludge treatment plants (FSTPs) in urban areas.
- It has also encouraged co-treatment of faecal sludge in existing sewage treatment plants (STPs).
- While these facilities form a strong backbone, the key challenge is extending their benefits to surrounding villages.
5. Urban–Rural Partnerships: The Satara Model
- A notable example comes from Satara district, Maharashtra.
- Satara city’s faecal sludge treatment plant (65 KLD capacity) was operating below capacity.
- Four nearby villages—Jakatwadi, Sonagon, Kodoli, and Degao—were linked to this facility.
- Through formal agreements between gram panchayats and the municipal council, villages gained access to urban treatment infrastructure.
- Septic tanks, earlier rarely desludged or emptied unsafely, are now serviced every five years in a safe and regular manner.
6. Governance and Financial Design
- Desludging services are provided by a private operator contracted by the gram panchayat.
- Costs are recovered through a modest sanitation tax, ensuring affordability and accountability.
- Authorised desludging vehicles are permitted to use the city’s treatment plant at no cost.
- This creates a mutually beneficial arrangement for both urban and rural local bodies.
7. Extending the Model: Cluster-Level Solutions
- Not all villages can be linked to city treatment plants.
- The article cites Mayani village in Khatav taluka as an alternative model.
- Due to high desludging demand, the gram panchayat introduced scheduled desludging every 5–7 years.
- Mayani is also part of a cluster-level faecal sludge treatment plant under SBM-G, designed to serve around 80 villages.
- This approach allows rural clusters to pool resources while ensuring technical and financial viability.
8. Institutionalising Urban–Rural Linkages
- Demonstrating the success of such partnerships helps:
- Standardise faecal sludge management practices
- Promote sustainable business models
- Scale safe sanitation services across the State
- The Satara experience highlights the need for collaboration between urban and rural governments, private players, and citizens.
Suggestions of the Author
- Shift focus from toilet construction to end-to-end sanitation systems.
- Promote urban–rural partnerships to optimise underutilised urban treatment infrastructure.
- Encourage scheduled desludging to replace reactive and unsafe practices.
- Develop cluster-level treatment plants where urban linkage is not feasible.
- Institutionalise sanitation services through formal agreements and local taxation.
- Strengthen coordination among government bodies, private operators, and communities.
UPSC Mains Question
“Faecal sludge management is the missing link in India’s sanitation journey.” Discuss how urban–rural partnerships can help achieve sustainable sanitation outcomes in rural India.
SC slams denial of bail to give accused a ‘taste of imprisonment as a lesson’
Context
The Supreme Court criticised the practice of denying bail to undertrials merely to subject them to imprisonment as a deterrent, while granting bail in a high-profile bank fraud case.
Key Points
Presumption of Innocence
- The Supreme Court reaffirmed that an undertrial remains presumed innocent.
- Mere allegations of “serious offence” or booking under a stringent law do not dilute this presumption.
Bail is the Rule, Jail is the Exception
- The Court reiterated a settled principle of criminal jurisprudence.
- Pre-trial incarceration should not become a form of punishment without conviction.
Limits on Pre-trial Detention
- Undertrials should not be detained indefinitely unless:
- There is a clear threat to society
- Possibility of influencing witnesses or tampering with evidence
- Risk of absconding
- Long incarceration without trial is constitutionally suspect.
Judicial Duty to Intervene
- Courts are constitutionally obligated to intervene when custody becomes:
- Disproportionate
- Arbitrary
- Excessive
- Delay in trial strengthens the case for bail.
Onus on Prosecution
- Bail is a qualified right before conviction.
- The burden lies on the prosecution to justify why bail should be denied.
Rejection of Punitive Approach
- The Court strongly disapproved denial of bail to “teach a lesson”.
- Criminal process cannot be used as punishment prior to adjudication.
Reliance on Precedents
- The Court referred to earlier rulings holding that when timely trial is unlikely and incarceration is prolonged, bail should ordinarily follow.

Assam tribal body rejects GoM proposal to grant ST status to six OBC communities
Context
The Coordination Committee of Tribal Organisations of Assam (CCTOA) has opposed the Assam government’s proposal to grant Scheduled Tribe status to six OBC communities, calling it unconstitutional and detrimental to existing tribal rights.
Key Points
Rejection by Tribal Body
- The CCTOA, representing 14 tribes of Assam, rejected the Group of Ministers (GoM) recommendations.
- The proposal seeks to grant ST status to six OBC communities:
- Koch-Rajbongshi
- Chutia
- Matak
- Moran
- Tai Ahom
- Tea Tribes (Adivasis)
Grounds of Objection
- The recommendations were termed illegal and unconstitutional.
- CCTOA stated that granting ST status would erode political and reservation rights of existing ST communities at all levels, from panchayats to the Lok Sabha.
Reservation Ceiling Concern
- Assam currently provides 59% reservation, already exceeding the Supreme Court-mandated 50% ceiling.
- If additional communities are granted ST status, reservation could exceed 70%, which the tribal body said is clearly unconstitutional.
Existing Reservation Structure in Assam
- SC: 7%
- ST (Plains): 10%
- ST (Hills): 5%
- OBC/MOBC (including Tea Tribes): 27%
- EWS: 10%
Criteria for ST Identification
- CCTOA highlighted that STs are identified based on tribal characteristics, not caste status.
- Key criteria include:
- Primitive traits
- Distinctive culture
- Geographical isolation
- Shyness of contact with the larger community
- Overall social and economic backwardness
- These criteria were laid down in the Lokur Committee Report, 1965.
Impact on Federal and Central Reservation
- Granting ST status to these communities may affect:
- Political reservation for existing STs
- Allocation of reservation benefits under Central schemes
- The move could dilute benefits meant for constitutionally recognised tribes.
Coordination Committee of Tribal Organisations of Assam (CCTOA)
- An umbrella body representing 14 recognised tribal organisations in Assam.
- Engages with policy issues affecting tribal identity, reservation, and constitutional safeguards.

Cetacean morbillivirus
Syllabus: GS 3 – Environment | Biodiversity | Conservation
Context
Scientists have detected cetacean morbillivirus in Arctic waters for the first time using drones to collect whale breath samples, marking a major advance in non-invasive marine disease surveillance.
About Cetacean Morbillivirus
What it is
- Cetacean morbillivirus is a highly infectious viral disease affecting marine mammals such as whales, dolphins, porpoises, and pilot whales.
- It is closely related to measles virus and canine distemper virus.
Regions found
- Previously reported in the North Atlantic, Mediterranean Sea, and Pacific Ocean.
- Newly detected in Arctic waters, particularly among humpback whales and sperm whales.
Origin
- First identified in 1987.
- Believed to have evolved from terrestrial morbilliviruses and later adapted to marine mammals.
Key Features
- System affected: Attacks the respiratory, immune, and nervous systems.
- Mode of transmission:
- Direct contact between animals
- Aerosolised respiratory droplets released through whale blow
- Cross-species spread: Can infect multiple cetacean species.
- Detection challenge: Often identified post-mortem, limiting early response.
Implications
- Mass mortality events: Associated with large-scale strandings and deaths of cetaceans.
- Arctic risk indicator: Presence in Arctic waters signals emerging disease threats in a fragile ecosystem.
- Climate change link: Changing ocean temperatures and altered migration routes may increase transmission.
- Conservation value:
- Drone-based blow sampling enables stress-free monitoring.
- Helps authorities plan protective and stress-reduction measures for infected populations.
- Biosecurity importance: Strengthens early-warning systems for marine wildlife health.
