Electronic waste, commonly referred to as e-waste, has become a pressing global concern in recent years due to the rapid proliferation of electronic devices and technology. With the constant upgrading and obsolescence of gadgets such as smartphones, laptops, and tablets, the volume of electronic waste generated worldwide has skyrocketed. This accumulation of discarded electronics poses significant environmental and health risks, as electronic devices often contain hazardous materials such as lead, mercury, and cadmium. However, amidst these challenges lies an opportunity for effective recycling and resource recovery. Implementing sustainable e-waste management practices can not only mitigate environmental pollution but also foster the extraction of valuable materials for reuse, thereby reducing the strain on natural resources and promoting a circular economy. In this essay, we will explore the generation of electronic wastes, the environmental implications, and the various strategies for recycling and managing e-waste sustainably.
ELECTRONIC WASTES
- E-waste, short for Electronic Waste, refers to electronic appliances that are outdated, at the end of their life, or have been abandoned.
- It encompasses all components, consumables, and spares associated with these devices.
- The metals within e-waste naturally release toxic compounds when buried, posing significant harm.
- Unregulated processing of e-waste, especially in developing nations, can have adverse effects on human health and contribute to environmental pollution.
E WASTES – SOURCES
| Particulars | Sources | Health Effects |
| Lead | Used in computer monitor gaskets and glass panels. Solder components and printed circuit boards. | Lead affects humans’ central and peripheral nervous systems, circulatory systems, kidneys, and reproductive systems. It also impacts the endocrine system and hampers brain development in children. |
| Cadmium | Found in SMD chip resistors, infrared detectors, and semiconductor chips. Present in certain older cathode ray tubes. | Toxic cadmium molecules accumulate in the human body, particularly in the kidneys. |
| Mercury | Electrical and electronic equipment contributes to 22% of global mercury consumption yearly. Found in thermostats, sensors, relays, switches, medical equipment, lamps, mobile phones, and batteries. | Mercury can harm organs such as the brain and kidneys, as well as the developing fetus. Inorganic mercury dissolves in water, converting to dimethyl mercury, which bioaccumulates in living species through the food chain. |
| Hexavalent Chromium/ Chromium VI | Used to protect steel plates and decorate steel housings. Present in PVC and plastics. | Chromium VI is hazardous in the environment and can damage DNA. PVC burning emits dioxin. |
| Barium | Used in computers to shield users from radiation in CRT front panels. | Short-term barium exposure causes brain enlargement, muscle weakness, and damage to the heart, liver, and spleen. |
| Beryllium | Found on many motherboards and finger clips. | Beryllium exposure can lead to lung cancer and a skin condition marked by slow wound healing and wart-like lumps. |
| Toners | Found in black and color toner cartridges of plastic printer cartridges. | Inhalation of toner particles can cause respiratory tract irritation. Carbon black in toners is recognized as a class 2B carcinogen. |
| Phosphor and Additives | Phosphor is placed on the inside of the CRT faceplate as a coat. Heavy metals like cadmium and rare earth metals like zinc and vanadium are used as additives in the phosphor coating. | These metals and their derivatives are extremely dangerous, posing severe risks to those deconstructing CRTs by hand. |
HOW TO REDUCE AND RECYCLE E-WASTE EFFECTIVELY
- Formalizing E-waste Collection:
- Creating a comprehensive regulatory framework for e-waste collection, which includes mandatory registration and licensing of collection centers and recyclers. This formalizes and standardizes the e-waste collection process.
- E-Waste Tax Credits for Manufacturers:
- Implementing a tax credit system to incentivize electronics manufacturers for designing products with extended lifespans and repairability features. This approach encourages eco-friendly design practices and discourages planned obsolescence.
- E-Waste ATMs:
- Installing E-Waste ATMs in public places, allowing individuals to deposit old electronic devices. In return, they receive small financial incentives or vouchers for public transportation or essential goods. These ATMs may also include educational displays to raise awareness about e-waste recycling.
- E-Waste Tracking and Certification:
- Establishing a blockchain-based system to track the entire lifecycle of electronic devices. Each device would have a digital certificate documenting its manufacturing, ownership, and disposal history. This facilitates tracing and holding responsible parties accountable for improper disposal.
- E-Waste Art and Awareness:
- Promoting awareness through art installations made from e-waste. Encouraging artists to create sculptures or exhibits in public spaces visually depicting the scale of the e-waste problem and raising awareness about proper disposal.
E-WASTE MANAGEMENT RULES 2016
Key Updates in E-Waste Management Rules:
1. Stakeholder Inclusions:
- The introduction of Producer Responsibility Organisation (PRO), manufacturer, dealer, and refurbisher as additional stakeholders.
2. Broadened Applicability:
- The rules now cover components, consumables, spares, and parts of Electrical and Electronic Equipment (EEE), expanding beyond the equipment listed in Schedule I.
3. Inclusion of Specific Products:
- Compact Fluorescent Lamps (CFLs) and other mercury-containing lamps are now subject to regulations.
4. Extended Producer Responsibility (EPR):
- A collection mechanism-based approach for EPR, incorporating collection centres, collection points, take-back systems, etc.
- Proposed channels for Producers to implement EPR include PRO, e-waste exchange, e-retailer, and Deposit Refund Scheme.
5. Pan-India EPR Authorization:
- Introduction of Pan-India EPR authorization, replacing the previous state-by-state authorization.
6. Collection Targets:
- Phased collection targets for e-waste, set out in Schedule III of the Rules, with a gradual increase over the years.
7. Deposit Refund Scheme:
- Introduction of the Deposit Refund Scheme as an economic instrument where producers charge a deposit at the time of sale and return it with interest upon returning end-of-life equipment.
8. Responsibility of Manufacturers and Dealers:
- Manufacturers now responsible for collecting e-waste generated during the manufacturing process.
- Dealers tasked with collecting e-waste must provide consumers with a box and channel it back to the producer.
9. Refurbishers’ Responsibilities:
- Refurbishers must collect e-waste generated during refurbishment and channel it to an authorized dismantler or recycler.
10. State Government Roles:
- Inclusion of State Government roles to ensure safety, health, and skill development of workers involved in dismantling and recycling operations.
11. Manifest System for Transportation:
- Adoption of the manifest system for the transportation of e-waste, with detailed documents provided by the sender.
12. Liability and Penalties:
- Establishment of liability for environmental or third-party damages due to improper e-waste management.
