Table of Contents

Introduction:

The Supreme Court of India recently termed the situation of untreated solid waste in Delhi and the National Capital Region (NCR) as “horrifying” and asked the Centre to convene a meeting with municipal authorities to find an immediate solution to the problem.

Concept of Solid Waste Management

According to the Solid Waste Management Rules, 2016, solid waste includes solid or semi-solid domestic waste, sanitary waste, commercial waste, institutional waste, catering and market waste and other non residential wastes, street sweepings, silt removed or collected from the surface drains, horticulture waste, agriculture and dairy waste, treated bio-medical waste excluding industrial waste, bio-medical waste and e-waste, battery waste, radio-active waste generated in the area under the local authorities and other entities.
Solid waste management involves the systematic control of waste generation, collection, storage, transportation, processing, and disposal. Its goals are to minimize environmental impact, protect health, and promote resource efficiency.

Solid Waste Generation in India

Due to rapid urbanization, economic growth and higher rates of urban consumption, India is among the world’s top 10 countries generating municipal solid waste (MSW).
a) Scale of Generation: According to a report by The Energy and Resources Institute (TERI), India generates over 62 million tons (MT) of waste in a year. Only 43 MT of total waste generated gets collected, with 12 MT being treated before disposal, and the remaining 31 MT simply discarded in wasteyards.
Most of the waste generated remains untreated and even unaccounted for. Inadequate waste collection, transport, treatment, and disposal have become major causes for environmental and public health concerns in the country.
b) Urban vs Rural: Urban areas contribute substantially to solid waste generation due to higher consumption patterns and population density. However, rural areas also generate significant waste, mainly agricultural and biomass residues.

Challenges posed by Solid Waste Management in India

Solid waste management in India faces numerous challenges, contributing to environmental, health, and urban management issues. Here are some key challenges:

a) Rapid Urbanization:

India’s rapid urbanization leads to increased solid waste generation as urban populations grow and consumption patterns change. Urban areas are major generators of solid waste, and the infrastructure often struggles to keep up with the pace of waste generation.

b) Inadequate Infrastructure:

Many cities and towns lack adequate infrastructure for solid waste management, including collection, transportation, and disposal facilities. This results in inefficient waste collection and disposal practices, such as open dumping and burning, which contribute to environmental pollution and health hazards.

c) Lack of Segregation at Source:

One of the critical challenges is the lack of segregation of waste at the source (household or commercial establishments). Without proper segregation of waste into recyclable, organic, and non-recyclable categories, effective recycling and resource recovery are hindered.

d) Informal Sector Involvement:

A significant portion of solid waste management in India is handled by the informal sector, including waste pickers and recyclers. While they play a crucial role in waste collection and recycling, they often work under poor conditions and without adequate support or recognition.

e) Public Awareness and Behavior Change:

There is a need for increased public awareness and community participation in solid waste management practices. Many people still lack awareness about the importance of waste segregation, recycling, and proper waste disposal methods.

f) Financial Constraints:

Municipalities often face financial constraints in implementing and maintaining solid waste management infrastructure and services. Limited budgets and funding sources can hinder the adoption of more sustainable waste management practices.

g) Technological and Innovation Gaps:

There is a need for technological innovations and solutions to improve solid waste management efficiency and sustainability. This includes advancements in waste-to-energy technologies, composting techniques, and recycling processes tailored to local conditions.

h) Policy Implementation and Enforcement:

While India has comprehensive solid waste management rules and regulations (Solid Waste Management Rules, 2016), effective implementation and enforcement at the local level can be challenging. Coordination between different levels of government and stakeholders is often lacking.

Detrimental effects of inadequate Solid Waste Management

Poor municipal solid waste management can have a range of harmful impacts on the environment, public health, and socio-economic aspects. Here are some specific harmful impacts:

a) Environmental Pollution:

Improper disposal of solid waste, such as open dumping and burning, releases harmful chemicals, greenhouse gases (including methane and carbon dioxide), and particulate matter into the atmosphere. This contributes to air pollution and climate change.

b) Water Contamination:

Inadequate landfill management and improper waste disposal can lead to leachate—a toxic liquid that forms as water filters through waste materials. Leachate can contaminate groundwater and surface water sources, posing risks to aquatic ecosystems and human health.

c) Soil Degradation:

Dumping of untreated solid waste directly onto land can degrade soil quality and fertility. The presence of heavy metals, plastics, and other non-biodegradable materials in waste can alter soil composition and harm soil organisms.

d) Health Hazards:

Poor waste management practices create breeding grounds for disease vectors such as mosquitoes, flies, and rodents. These vectors can spread diseases like malaria, dengue, cholera, and typhoid fever among nearby communities.

e) Aesthetic and Social Impact:

Accumulation of waste in public spaces and improper disposal sites can degrade the aesthetic appeal of neighborhoods and cities. This can affect tourism, property values, and overall quality of life for residents.

f) Impact on Wildlife:

Improperly managed waste can harm wildlife through ingestion of plastics and other hazardous materials, entanglement in waste, and habitat destruction due to landfill expansion and pollution.

g) Economic Costs:

Inefficient waste management practices impose economic costs on municipalities and governments due to increased healthcare expenditures (treating waste-related illnesses), environmental remediation costs, and loss of tourism revenue.

h) Climate Change:

Landfills are significant sources of methane—a potent greenhouse gas that contributes to global warming. Inefficient waste management practices exacerbate climate change impacts through methane emissions from decomposing organic waste.

i) Social Inequities:

Poor waste management disproportionately affects marginalized communities, who often live near dumping sites or work in informal waste collection sectors. They bear the brunt of health risks and environmental degradation associated with inadequate waste management.

Government interventions for Solid Waste Management

The Indian government has implemented several laws, policies, and initiatives to address solid waste management issues across the country. Here are some key interventions:

a) Laws and Regulations:

i) Solid Waste Management (SWM) Rules, 2016: These rules provide the regulatory framework for solid waste management in India. They emphasize waste segregation at source, responsibilities of waste generators, and guidelines for waste processing and disposal. The rules also promote recycling and resource recovery.
ii) Environmental Protection Act, 1986: While not solely focused on solid waste, this act provides the legal basis for environmental governance in India. It empowers the government to regulate and control activities that may have adverse environmental impacts, including those related to solid waste management.

Major Highlights of the New SWM Rules, 2016

a) Segregation at Source

• Mandate: Waste generators must segregate waste into three streams: Biodegradables, Dry (Plastic, Paper, Metal, Wood, etc.), and Domestic Hazardous waste (diapers, napkins, mosquito repellants, cleaning agents, etc.).

• Responsibilities: Institutional generators, market associations, event organizers, and hotels/restaurants must manage waste in partnership with local bodies. Events with over 100 attendees must ensure waste segregation.

• Specific Requirements: Hotels and restaurants must segregate biodegradable waste and set up systems for composting/biomethanation. Residential and market associations, as well as gated communities with areas over 5,000 sq m, must segregate and hand over recyclable materials to authorized entities or local bodies.

b) Collection and Disposal of Sanitary Waste

• Manufacturer Responsibility: Producers of sanitary napkins must provide disposal pouches/wrappers and raise awareness about proper disposal methods.

c) Collect Back Scheme for Packaging Waste

• Brand Owners’ Role: Companies must implement systems to collect back non-biodegradable packaging waste generated by their products.

d) User Fees for Collection

• Local Bodies’ Authority: Municipal authorities can levy user fees for waste collection, disposal, and processing from bulk generators. Fines for littering and non-segregation will be decided by local bodies.

• Integration of Informal Sector: Rag pickers, waste pickers, and kabadiwalas will be integrated into the formal sector by the state government.

e) Waste Processing and Treatment

• Bio-Degradable Waste: Should be processed and disposed of through composting or bio-methanation within premises as much as possible. Residual waste should be handed over to designated waste collectors.

• Facility Requirements: Local bodies with populations over 1 million must set up waste processing facilities within two years. Those with populations between 0.5 million and 1 million must do so within three years. Sanitary landfills must be set up accordingly.

f) Promoting Use of Compost

• Government Support: The Department of Fertilisers must provide market development assistance for city compost and promote co-marketing with chemical fertilizers. The Ministry of Agriculture should support the manufacturing and sale of compost, propagate its use in agriculture, and set up testing laboratories.

g) Promotion of Waste-to-Energy

• Fuel Replacement: Industrial units within 100 km of a solid waste-based Refuse-Derived Fuel (RDF) plants must replace at least 5% of their fuel with RDF.

• Energy Utilization: Non-recyclable waste with a calorific value of 1500 Kcal/kg or more should be used for generating energy through RDF or co-processing in cement/thermal power plants.

• Subsidies and Tariffs: The Ministry of New and Renewable Energy Sources should facilitate infrastructure and provide subsidies for Waste-to-Energy plants. The Ministry of Power should set tariffs for energy generated from waste and ensure its compulsory purchase by distribution companies.

h) Revision of Parameters and Existing Standards

• Landfill Regulations: Landfill sites must be distanced from rivers, ponds, highways, habitations, public parks, and water supply wells. Specific distances are mandated (100-500 meters based on type and location).

• Emission Standards: Updated standards include parameters for dioxins, furans, and reduced particulate matter limits.

i) Management of Waste in Hilly Areas

• Landfill Restrictions: Construction of landfills on hills is discouraged. Instead, landfills should be constructed in plains within 25 kilometers. Transfer stations and processing facilities should operate in hilly areas.

j) Central Monitoring Committee

• Committee Formation: A Central Monitoring Committee chaired by the Secretary of MoEF&CC will oversee rule implementation. This committee, including various stakeholders from central and state governments, will meet annually to review progress.

b) Government Initiatives and Programs:

i) Swachh Bharat Mission (SBM): Launched in 2014, SBM is a national cleanliness campaign aimed at achieving universal sanitation coverage and eliminating open defecation. It includes components for solid waste management, such as construction of household toilets, public awareness campaigns, and infrastructure development for waste collection and processing.
ii) Atal Mission for Rejuvenation and Urban Transformation (AMRUT): AMRUT, launched in 2015, focuses on improving infrastructure in cities, including water supply, sewerage, and solid waste management. It aims to ensure basic services are available to all urban residents, with specific funding allocated for solid waste management projects.
iii) Smart Cities Mission: This mission, launched in 2015, aims to transform selected cities into smart cities by improving urban infrastructure and services. Solid waste management is a key component of this initiative, with emphasis on technology-driven solutions, waste segregation, and recycling.
iv) National Mission on Clean Ganga (Namami Gange): While primarily focused on cleaning and conserving the Ganga River, Namami Gange includes initiatives for solid waste management in cities along the river basin. It promotes sustainable waste management practices to reduce pollution entering the river.
