Electronic products that are unwanted, broken, or nearing or exceeding their "useful life" are classified as e-wastes. Everyday electrical items that generate wastes include computers, televisions, VCRs, stereos, copiers, and fax machines. The problem of how to properly dispose of used and unwanted electronics isn't new; it traces back to at least the 1970s. E-waste is not harmful if it is stored in a safe place, recycled using scientific processes, or transferred in parts or in its entirety in the formal sector. However, e-waste that is recycled using primitive technologies might be harmful. This article will explain to you about E–Waste which will be helpful in preparing the Environment syllabus for the UPSC Civil service exam.

What exactly is an E–Waste?

• Electronic-Waste (E-Waste) is a term that describes outdated, end-of-life, or abandoned electronic appliances. It contains all of their parts, consumables, and spares.
• Toxic compounds naturally leak from the metals inside e-waste when it is buried, making it particularly harmful.
• Informal or uncontrolled e-waste processing, particularly in developing countries, can be harmful to human health and pollute the environment.

E-waste - Sources

E-waste - Impacts

On Environment

• The manufacturing, reprocessing, and disposal of electrical and electronic equipment creates an interface between the e-wastes and the environment.
• Environmental degradation is caused by the release of fumes, gases, and particulate matter into the air, the discharge of liquid waste into water and drainage systems, and the dumping of hazardous wastes.
• There are several ways in which e-waste recycling can be harmful to the environment.
• Burning wires and cables to recover metal produces brominated and chlorinated dioxins, which pollute the air.
• Toxic substances with little commercial value are simply discarded during the recycling process in the informal sector.
• Toxic industrial effluent is pumped into subsurface aquifers, causing major groundwater contamination and rendering the water unfit for human consumption or agricultural use.
• Dismantling activities pollute the atmosphere by releasing dust particles laden with heavy metals and flame retardants into the atmosphere.
• These particles either redeposit (wet or dry deposition) near the emission source or can be carried over vast distances, depending on their size.
• The dust can also infiltrate the soil or water systems, where it can combine with compounds found in wet and dry depositions to pollute the land and water.
• When dangerous compounds including lead, mercury, cadmium, arsenic, and polychlorinated biphenyls (PCBs) are dumped in landfills, they contaminate the soil causing soil pollution.

On Human Health

• Human health is harmed by the complicated nature and inappropriate treatment of e-waste.
• An increasing amount of epidemiological and clinical evidence has raised concerns about the potential hazard of e-waste to human health, particularly in emerging nations like India and China.
• Processes such as dismantling components, wet chemical processing, and cremation results in direct chemical exposure and inhalation.
• Gloves, face masks, and ventilation fans are nearly unknown, and workers sometimes have no idea what they're dealing with.
• In terms of health risks, open burning of printed circuit boards, for example, raises dioxin levels in the surrounding environment.
• Inhalation of these chemicals by workers and locals increases the risk of cancer.
• During the laborious extraction and collecting of small amounts of precious metals, toxic metals and poison can enter the bloodstream, and employees are constantly exposed to dangerous chemicals and vapours of extremely concentrated acids.
• Burning insulated wires to recover resalable copper causes neurological problems, and acute exposure to cadmium, which is contained in semiconductors and chip resistors, can harm the kidneys and liver, as well as induce bone loss.
• Long-term exposure to lead from printed circuit boards, computer and television screens can impair the central and peripheral neurological systems as well as the kidneys, with children being particularly vulnerable.

E-Waste in India

• India created more than 10 lakh tonnes of e-waste in 2019-20, up from 7 lakh tonnes in 2017-18, according to the Central Pollution Control Board (CPCB), with Mumbai and Delhi-NCR accounting for the largest share.
• Other major cities that generate significant amounts of e-waste include Bangalore, Chennai, Kolkata, Ahmadabad, Hyderabad, Pune, Surat, and Nagpur.
• However, since 2017-18, the e-waste dismantling capacity has remained unchanged at 7.82 lakh tonnes.
• The Ministry of Environment told the tribunal in 2018 that the informal sector recycles 95% of e-waste in India, and scrap dealers dispose of it unscientifically by burning or dissolving it in acids.
• More than half of the e-waste produced in developed countries is sent to developing countries, mostly China, India, and Pakistan, where metals such as copper, iron, silicon, nickel, and gold are recovered during the recycling process.
• Unlike developed nations, which have dedicated facilities for e-waste recycling, developing countries' recycling often requires human labour, exposing workers to harmful compounds found in e-waste.

E-Waste Management Rules, 2016

• The E-Waste Management Rules, 2016 were notified by the Ministry of Environment, Forest and Climate Change, and they replaced the E-Waste (Management & Handling) Rules, 2011.
• Over 21 products (Schedule-I) were included in the rule's purview. It comprised compact fluorescent lights (CFLs), as well as other mercury-containing bulbs and equipment.
• For the first time, the rules imposed Extended Producer Responsibility (EPR) on producers, as well as targets.
• Producers have been given responsibility for collecting and exchanging E-waste.
• Various producers can each have their own Producer Responsibility Organization (PRO) to ensure that E-waste is collected and disposed of in an environmentally friendly manner.
• The Deposit Refund Scheme was introduced as an additional economic instrument.
• Under this scheme, the producer charges an additional amount as a deposit at the time of sale of electrical and electronic equipment and then returns it to the consumer with interest when the end-of-life electrical and electronic equipment is returned.
• State governments have also been given a role in ensuring the safety, health, and skill development of personnel working in dismantling and recycling activities.
• A punishment provision for breaking the rules has also been added.
• The task of collecting and channelling orphan products to authorised dismantlers or recyclers has been given to Urban Local Bodies (Municipal Committee/ Council/ Corporation).
• E-waste dismantling and recycling should be given adequate space in existing and future industrial facilities.

Conclusion

The e-waste problem is a matter of global concern. Although electronics have become an indispensable element of daily life, their negative effects on the environment must not be neglected. It's difficult to estimate exactly the global amount of e-waste, but it's known that large amounts end up in places where proper recycling facilities aren't yet in place, and primitive methods are used to recover valuable components while hazardous components are disposed of in often uncontrolled landfills. This raises concerns about resource efficiency as well as immediate health and environmental concerns. Many countries, on the other hand, have recognised the need to properly recycle e-waste and are working to implement long-term solutions. In addition to stricter e-waste recycling and disposal regulations, policies that extend the duty of all stakeholders, notably producers, beyond the point of sale and up to the end of product life are required.

GS Mains Questions and Model Answers

Q1: Discuss the environmental and health impacts of improper e-waste disposal.

Answer: Improper e-waste disposal releases hazardous substances like lead, cadmium, and mercury, contaminating soil, water, and air. These toxins enter ecosystems, harming plant and animal life and disrupting biodiversity. Humans are affected through water pollution and food contamination, leading to health issues such as respiratory problems, organ damage, and neurological disorders. Sustainable disposal methods, especially recycling and responsible producer practices, are essential to mitigate these risks.

Q2: Explain the concept of Extended Producer Responsibility (EPR) in e-waste management.

Answer: EPR is a policy approach where manufacturers are accountable for the lifecycle of their products, including end-of-life disposal. This responsibility requires companies to implement systems for collecting, recycling, and properly disposing of e-waste. EPR aims to reduce the environmental footprint of electronic goods, encourage eco-friendly design, and lessen landfill burden by ensuring that valuable materials are recovered and harmful substances are managed safely.

Q3: Analyze India’s E-Waste (Management) Rules, 2016, and their role in sustainable waste management.

Answer: The E-Waste (Management) Rules, 2016, emphasize Extended Producer Responsibility, requiring producers to manage e-waste through collection, recycling, and safe disposal. These rules mandate eco-friendly recycling facilities, banning informal sector processing that poses health risks. While aiming to create a circular economy, challenges remain in enforcement and awareness. However, the rules are a significant step toward reducing pollution, conserving resources, and promoting sustainability in India.

2. UPSC CSE Mains 2020

Question: Critically analyze the challenges and opportunities of e-waste management in India, with particular reference to the informal sector.

Answer: E-waste management in India faces challenges such as inadequate infrastructure, low public awareness, and the dominance of the informal sector, which processes 90% of e-waste without safety standards. The informal sector lacks proper disposal methods, leading to toxic emissions that harm human health and the environment. However, the sector also offers employment to many. Formalizing it, through training and technological support, could transform this workforce into a valuable part of India’s waste management system. The E-Waste (Management) Rules, 2016, offer a framework to engage producers and promote recycling, yet effective implementation and stricter enforcement are essential for addressing the vast quantities of e-waste generated.
