Hazardous Waste Pollution in India: Radioactive, Electronic, and Biomedical Waste Challenges

India’s rapid industrialisation and urbanisation have brought an uncomfortable companion – hazardous waste. From toxic chemical by-products of manufacturing to radioactive residues from nuclear plants, discarded electronics piling up in informal scrapyards, and biomedical waste flowing out of an expanding healthcare sector, the country faces a multi-dimensional waste crisis. Understanding the scale, sources, and specific challenges of each hazardous waste stream is crucial for anyone studying sustainable development in India.

The scale of hazardous waste generation in India 🔗

India is one of the world’s largest generators of hazardous waste. Approximately 4.43 million tonnes of hazardous waste are produced annually in India, of which about 71,833 tonnes are categorised as incinerable, according to reports submitted by State Pollution Control Boards (SPCBs) to the Supreme Court. Of this total, roughly 38.3% is recyclable, 4.3% is suitable for incineration, and the remaining bulk requires disposal in secured landfills.

By financial year 2022, India’s hazardous waste output had crossed 12 million metric tonnes – a record high – with nearly half classified as utilizable waste. This sharp increase reflects both industrial expansion and improved reporting mechanisms. Gujarat alone generated over 4.2 million metric tonnes in FY 2022, making it the largest contributor and accounting for more than one-third of the national total. Maharashtra, Andhra Pradesh, and Odisha were other major producing states.

Twelve states collectively account for approximately 87% of all hazardous waste generated in the country, with the western and southern industrial belts bearing the heaviest burden. Despite regulations under the Hazardous Waste (Management and Handling) Rules, a substantial portion of waste still ends up in open dumps or untreated water bodies, particularly from small-scale industries.

Radioactive waste pollution 🔗

Radioactive waste is among the most dangerous categories of hazardous waste because of its ability to remain harmful for decades, centuries, or even millennia. India’s nuclear programme, while essential for energy security, generates radioactive waste at every stage – from uranium mining and fuel fabrication to reactor operations and spent fuel reprocessing.

Sources of radioactive waste 🔗

The primary sources of radioactive waste in India include the nuclear fuel cycle (power reactors, reprocessing plants), medical and industrial applications of radioisotopes, and research activities. India follows a closed fuel cycle, where spent fuel is reprocessed to recover plutonium and unused uranium, unlike countries such as the USA and Canada where spent fuel is stored as waste. Additionally, naturally occurring radioactive materials (NORM) get concentrated during fossil fuel processing, particularly in coal-fired power plants, adding another layer to the radioactive waste inventory.

Classification and management 🔗

India follows international standards set by the IAEA for classifying radioactive waste into low-level, intermediate-level, and high-level categories. The core objective of India’s radioactive waste management programme is the protection of human health, the environment, and future generations. Low and intermediate-level wastes are treated using chemical precipitation, ion exchange, and evaporation techniques, then immobilised in cement or polymer matrices before being placed in near-surface disposal facilities.

High-level waste (HLW), which contains about 99% of the total radioactivity in the fuel cycle, is converted into stable borosilicate glass through a process called vitrification. India is one of the few countries to have mastered this technology, operating vitrification plants at Trombay and Tarapur with a third facility at Kalpakkam.

The Chernobyl and Fukushima lessons 🔗

The catastrophic nuclear disasters at Chernobyl (1986) and Fukushima (2011) serve as stark reminders of what can go wrong with radioactive materials. Both incidents released massive amounts of radiation into the environment, causing long-term health consequences including increased cancer rates and birth deformities in affected populations. These events have made radioactive waste management a high-priority issue globally, including in India, where the Atomic Energy Regulatory Board (AERB) enforces safety standards aligned with IAEA guidelines.

Electronic waste: a rapidly growing threat 🔗

Electronic waste, or e-waste, is one of the fastest-growing waste streams in India. As consumer electronics become cheaper and product life cycles shrink, the volume of discarded phones, computers, televisions, and appliances has surged dramatically.

Scale of e-waste generation 🔗

According to the Central Pollution Control Board (CPCB), India generated approximately 16,01,155 tonnes (1.6 million tonnes) of e-waste in FY 2021-22 from 21 types of notified electrical and electronic equipment. This represents a massive jump from earlier estimates – e-waste was projected at just 146,180 tonnes in 2005 and around 800,000 tonnes by 2012.

India experienced the highest growth globally – 163% – in generating e-waste from screens, computers, and small IT equipment between 2010 and 2022, according to a UN Trade and Development report. The country’s share of global e-waste in this category doubled from 3.1% in 2010 to 6.4% in 2022. Computer devices account for nearly 70% of e-waste, followed by the telecom sector at 12% and medical equipment at 8%.

The informal recycling challenge 🔗

More than 95% of India’s e-waste is illegally recycled by informal waste pickers known as kabadiwalas or raddiwalas (scrap traders), who operate independently outside any formal organisation. These workers use crude techniques – open burning of cables to extract copper, acid baths to recover precious metals – that release toxic pollutants like lead, mercury, cadmium, and brominated flame retardants into the air, soil, and water.

India lacks sufficient large-scale organised e-waste recycling infrastructure. The formal sector comprises approximately 450 authorised recycling facilities registered with CPCB as of 2024, though these handle only about 40-45% of the total e-waste generated. The geographic distribution is also uneven – Maharashtra, Tamil Nadu, and Andhra Pradesh are the top e-waste producing states, with 65 cities generating more than 60% of India’s total e-waste.

Regulatory response 🔗

The Ministry of Environment, Forest and Climate Change notified the E-Waste (Management) Rules, 2022, which came into force in April 2023. These rules establish an improved Extended Producer Responsibility (EPR) regime requiring manufacturers, producers, refurbishers, and recyclers to register on a CPCB-managed portal. The regulations aim to channelise informal sector operations into formal pathways and promote circular economy principles. Recycling targets start at 60% collection for FY 2023-24 and increase to 80% by FY 2027-28, with environmental compensation provisions and verification audits to ensure compliance.

Biomedical waste: handling challenges in healthcare 🔗

Biomedical waste includes any waste generated during the diagnosis, treatment, or immunisation of humans and animals – syringes, needles, soiled bandages, discarded organs, blood bags, expired pharmaceuticals, microbiological cultures, and contaminated plastics. This waste poses an elevated risk of infection and injury compared to most other waste types.

Current generation and capacity 🔗

India generates approximately 700 tonnes of biomedical waste per day (TPD), of which about 640 TPD is treated, even though the combined treatment capacity of Common Biomedical Waste Treatment Facilities (CBWTFs) stands at 1,590 TPD. This gap between generation and treatment – and the underutilisation of existing capacity – points to systemic inefficiencies in collection, segregation, and transportation.

There are approximately 393,242 healthcare facilities (HCFs) in the country, with around 67.8% being non-bedded facilities like clinics, laboratories, and dispensaries. About 79% of HCFs currently use the services of 218 operational CBWTFs. However, seven states and union territories – Andaman & Nicobar Islands, Arunachal Pradesh, Lakshadweep, Mizoram, Nagaland, Sikkim, and Ladakh – have no CBWTFs at all.

Key challenges in biomedical waste management 🔗

The biggest challenges in managing biomedical waste in India are poor segregation at source, lack of awareness among healthcare workers, and inadequate infrastructure in rural and remote areas.

A comprehensive review of biomedical waste management practices in India found that lack of awareness, inadequate monitoring infrastructure, and non-compliance with recycling practices are persistent challenges. Many hospitals still dispose of infectious and non-infectious waste together, raising contamination risks. India’s waste management system is characterised by improper segregation, with hospital waste frequently getting mixed with general municipal waste, creating harmful overall waste flows.

The COVID-19 pandemic exposed these weaknesses further. During the pandemic, daily biomedical waste generation spiked significantly, with COVID-19 related waste adding 15-20% to the existing burden, yet the number of treatment facilities remained the same. PPE kits, masks, gloves, testing kits, and vaccine waste overwhelmed an already strained system.

Regulatory framework 🔗

The Biomedical Waste Management Rules, 2016 set comprehensive standards for segregation, collection, treatment, and disposal. Waste must be separated into colour-coded categories – yellow for incineration, red for autoclaving, white for sharps, and blue for glassware. Healthcare facilities are required to obtain authorisation from SPCBs and use either CBWTFs or approved captive treatment methods.

The CPCB has recommended time-bound authorisation of all healthcare facilities, limited use of captive treatment, vigilant monitoring of emission systems, and comprehensive training for healthcare workers. A centralised barcode tracking system for biomedical waste has been adopted by 208 of the 218 operational CBWTFs to improve transparency and traceability.

The interconnected nature of hazardous waste challenges 🔗

What makes India’s hazardous waste problem particularly complex is that these waste streams do not exist in isolation. E-waste contains heavy metals and toxic chemicals that classify it as hazardous. Biomedical waste from diagnostic imaging includes low-level radioactive materials. Industrial hazardous waste contaminates the same land and water systems that are already stressed by improper e-waste recycling and biomedical waste dumping.

The increasing volume of all three types of waste – radioactive, electronic, and biomedical – is also an indicator of growing economic activity, healthcare demand, and technological adoption. This makes it clear that waste management cannot be an afterthought; it must be integrated into industrial planning, product design (through extended producer responsibility), healthcare protocols, and nuclear energy policy from the start.

India has made significant regulatory progress with dedicated rules for hazardous waste, e-waste, and biomedical waste. But enforcement remains the critical gap. SPCBs are often under-resourced, informal sector activities are difficult to regulate, and public awareness about proper waste handling remains low across all categories.

Moving toward sustainable hazardous waste management 🔗

Addressing India’s hazardous waste challenge requires action on multiple fronts. For radioactive waste, continued investment in vitrification technology and deep geological repository research is essential. For e-waste, expanding formal recycling infrastructure and strictly enforcing EPR obligations will help bring the informal sector into compliant channels. For biomedical waste, building CBWTFs in underserved regions, training healthcare workers in proper segregation, and deploying digital tracking systems are immediate priorities.

Crucially, the circular economy approach – where waste is seen as a resource to be recovered and reused – needs to become the guiding principle across all hazardous waste streams. With the right combination of regulation, technology, awareness, and investment, India can turn its waste challenge into an opportunity for sustainable development.

What do you think? Should India prioritise building formal e-waste recycling facilities in every major city, or would investing in training and formalising the existing informal recycling workforce be a more effective approach? How can hospitals in rural India, far from any treatment facility, be expected to comply with biomedical waste management rules?
