Responsibility of producers:- A growing number of companies are taking on greater levels of responsibility for the environmental impacts of their products -- from point of manufacturing through to end of the life recycling. E-waste recycling is taking off, but obstacles remain to its widespread practice . Government co-operation:- The electronic waste sector will create 4.5 lakh direct jobs in form of recycling and repair factories. And another 1.8 lakh jobs in secondary allied sectors of transportation, storage, and waste separation. The IFC, which has been working in the e-waste sector since 2012.Under swach bharat abhiyan further 40% of e- waste is aimed to be removed till 2025.

COMPARISON OF COUNTRIES:- IF look at the graph we will find that the e-waste generated by developed countries per person is high and developing countries is low But at the same time when we look at the other side about total waste we will find that india is highest whereas sri lanka is lowest. coclusion Import of e-waste:- The us is ranked top in acquiring the highest share of importing electronic waste mainly to developing countries where such laws regarding e- waste is not very rigid and can be easily exploitated.india’s e-waste imports,us has a maximum of 42%,china at around 29.7%,whereas the rest with Europe,Taiwan,south korea ,etc. Awareness program:- The programme aims to create effective awareness in various levels (of society) to reduce the adverse impact on environment and health arising out of the polluting technologies used in recycling e-waste in the unorganized sector. OUR INVOLVEMENT The charter for this programme is to bring together the triad of public, government and industry to adopt responsible measures for Sustainable electronics that is responsive to environmental needs. This needs proactive policy formation and mass deployment that would be the focus area. Awareness program in maharastra:-

> AUSTRALIA:- For almost two decades waste electrical and electronic equipment, WEEE or e-waste, has been considered a growing problem that has global consequences. The value of recovered materials, primarily in precious and base metals, has prompted some parts of the world to informally and inappropriately process e-waste causing serious environmental and human health issues. Efforts in tackling this issue have been limited and in many ways unsuccessful. The global rates for formal e-waste treatment are estimated to be below the 20% mark, with the majority of end-of-life (EoL) electronic devices still ending up in the landfills or processed through rudimentary means. Industrial confidentiality regarding device composition combined with insufficient reporting requirements has made the task of simply characterizing the problem difficult at a global scale. To address some of these key issues, this paper presents a critical overview of existing statistics and estimations for e-waste in an Australia context, including potential value and environmental risks associated with metals recovery. From our findings, in 2014, on average per person, Australians purchased 35 kg of electrical and electronic equipment (EEE) while disposed of 25 kg of WEEE, and possessed approximately 320 kg of EEE. The total amount of WEEE was estimated at 587 kt worth about US$ 370 million if all major metals are fully recovered. These results are presented over the period 2010–2014, detailed for major EEE product categories and metals, and followed by 2015–2024 forecast. Our future projection, with the base scenario fixing EEE sales at 35 kg per capita, predicts stabilization of e-waste generation in Australia at 28–29 kg per capita, with the total amount continuing to grow along with the population growth. > GRAPHICAL REPRESENTATION:- COUNTRIES REGION POPULATION(1000) E-WASTE E-WASTE AUSTRALIA GENERATED(G/INH) GENERATED(KT) OCEANIA 24357 236000 574000 BANGLADESH ASIA 161513 9000 142000 INDIA ASIA 1309713 15000 1975000 SRI LANKA ASIA 21252 45000 95000 SRI LANKA E-WASTE GENERATED(KT) COUNTRIES INDIA E-WASTE BANGLADESH GENERATED(G/INH ) AUSTRALIA POPULATION(1000) 0 2000000 E-WASTE GENERATED REGION

REGIONAL E- WASTE > INDIA:- Electronic waste is emerging as a serious public health and environmental issue in India. India is the \"fifth largest electronic waste producer in the world\"; approximately 2 million tons of e-waste are generated annually and an undisclosed amount of e-waste is imported from other countries around the world. Discarded electronic waste. Annually, computer devices account for nearly 70% of e-waste, 12% comes from the telecom sector, 8% from medical equipment and 7% from electric equipment. The government, public sector companies, and private sector companies generate nearly 75% of electronic waste, with the contribution of individual household being only 16%. E-waste is a popular, informal name for electronic products nearing the end of their \"useful life.\" Computers, televisions, VCRs, stereos, copiers, and fax machines are common electronic products. Many of these products can be reused, refurbished, or recycled. There is an upgradation done to this E-waste garbage list which includes gadgets like smartphone , tablets, laptops, video game consoles, cameras and many more. India had 1.012 billion active mobile connections in January 2018. Every year the number is growing exponentially. > SRI LANKA:- In Sri Lanka, mobile phone penetration increased from 96% to 126% from 2012 to 2017, while annual growth rates estimated for other major electronic items, such as personal computers, televisions, printers, and batteries increased from 4% to 10%. But policies to monitor e-waste disposal have been slow to catch up. There is no formal disposal system in Sri Lanka for e-waste. Thus, we burn plastic items and crush burnt-out bulbs. Most hazardous waste matter is currently disposed of in a haphazard manner on roadsides, in dump yards and sometimes in home gardens. > BANGLADESH:- Electronic waste (e-waste) is one of the fastest-growing pollution problems worldwide given the presence if a variety of toxic substances which can contaminate the environment and threaten human health, if disposal protocols are not meticulously managed. In Bangladesh almost 2.7 million metric tons of e-waste generated per year. Of this amount only 20 to 30 percent is recycled and the rest of the waste is released in to landfills, rivers, drains lakes, canals, open spaces which are very hazardous for the health and environment. Since Bangladesh is in the stream of rapid technological advancement, it is seldom to take necessary steps to avoid the future jeopardized situation because of e-waste. The current practices of e-waste management in Bangladesh suffer from a number of drawbacks like the difficulty in inventorisation, unhealthy conditions of informal recycling, inadequate legislation and policy, poor awareness and reluctance on part of the corporate to address the critical issues. The paper highlights the associated issues and strategies to address this emerging problem, analyses the policy and its gaps. Therefore, this paper also suggest that e-waste policy development may require a more customized approach where, instead of addressing e-waste in isolation, it should be addressed as part of the national development agenda that integrates green economy assessment and strategic environmental assessment as part of national policy planning. Finally this work also suggests some alternative strategies and approaches to overcome the challenges of e-waste.

# POLLUTANTS:- Some computer components can be reused in assembling new computer products, while others are reduced to metals that can be reused in applications as varied as construction, flatware, and jewellery. Substances found in large quantities include epoxy resins, fiberglass, PCBs, PVC (polyvinyl chlorides), thermosetting plastics, lead, tin, copper, silicon, beryllium, carbon, iron, and aluminium. Elements found in small amounts include cadmium, mercury, and thallium. Elements found in trace amounts include americium, antimony, arsenic, barium, bismuth, boron, cobalt, europium, gallium, germanium, gold, indium, lithium, manganese, nickel, niobium, palladium, platinum, rhodium, ruthenium, selenium,silver, tantalum, terbium, thorium, titanium, vanadium, and yttrium. Almost all electronics contain lead and tin (as solder) and copper (as wire and printed circuit board tracks), though the use of lead-free solder is now spreading rapidly. The following are ordinary applications: # DEALING WITH E- WASTE:- RECYCLING Recycling is an essential element of e-waste management. Properly carried out, it should greatly reduce the leakage of toxic materials into the environment and mitigate against the exhaustion of natural resources. However, it does need to be encouraged by local authorities and through community education. Less than 20% of e-waste is formally recycled, with 80% either ending up in landfill or being informally recycled CONSUMER AWARENESS The U.S. Environmental Protection Agency encourages electronic recyclers to become certified by demonstrating to an accredited, independent third party auditor that they meet specific standards to safely recycle and manage electronics. This should work so as to ensure the highest environmental standards are being maintained. Two certifications for electronic recyclers currently exist and are endorsed by the EPA. DISPOSABLE METHOD Electronic waste can be disposed of by burial, burning, or dissolution and recovery of metals. All processes require proper containment to prevent contamination of air, groundwater, or soil with heavy metals such as lead or cadmium, or toxic combustion products. REPAIR AS A MEANS OF REDUCE One other important measure to curb the generation of electronic waste is to rent rather than out rightly buy a specific piece of electronic equipment which is not used everything.For example, if you sparingly use industrial weighing scales for measuring, rent the scales instead of buying them. # HOW MUCH E-WASTE IS A WASTE:- A large number of what is labelled as “e-waste” is not actually not waste at all,but rather whole electronic equipment or parts that are readily marketable for reuse or can be recycled for materials recovery.

GROWTH OF E- INDUSTRIES # A SHORT HISTORY:- The electronics industry emerged in the 20th century and is today one of the largest global industries. Contemporary society uses a vast array of electronic devices built in automated or semi-automated factories operated by the industry. Products are primarily assembled from metal- oxide-semiconductor (MOS) transistors and integrated circuits, the latter principally by photolithography and often on printed circuit boards. The size of the industry and the use of toxic materials, as well as the difficulty of recycling has led to a series of problems with electronic waste. International regulation and environmental legislation has been developed in an attempt to address the issues. The electronics industry consists of various sectors. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018.The largest industry sector is e-commerce, which generated over $29 trillion in 2017.The most widely manufactured electronic device is the metal-oxide-semiconductor field-effect transistor (MOSFET), invented in 1959, which is the \"workhorse\" of the electronics industry. # ENVIRONMENTAL CONCERNS AND HEALTH HAZARDS OF E- WASTE:- Air Pollution Many rudimentary e-waste “processing plants” are not ethically run – or safe. For example, some e- waste traffickers burn open computer wires in order to get to the copper inside – a valuable commodity. The open burning can release hydrocarbons into the air, while the chemical stripping of gold-plated computer chips leads to emissions of brominated dioxins and heavy metals. A recent study of the environmental effects of the largest e-waste landfill in the world in Guiyu, China, found airborne dioxins to be 100 times more prevalent than previously measured. Water Pollution Cathode ray tubes, often found in older televisions, video cameras and computer monitors are often broken apart, the yoke removed and the shell dumped. Contents in the shell, such as lead and barium, could leach through the soil and into the ground water of local communities. This endangers not just the people who drink and bathe with this water but also the different species of wildlife that rely on the water to sustain. Another study of the Guiyu landfill found wind patterns in Southeast China disperse toxic particles across the Pearl River Delta Region. The area, which contains a population of 45 million, is at-risk due to the toxins entering the “soil-crop-food pathway,” which is one of the most common ways that heavy metals enter the human body.

O e-waste generation in india:- India ranks 177 amongst 180 countries and is amongst the bottom five countries on the Environmental Performance Index 2018, as per a report released at the World Economic Forum 2018. This was linked to poor performance in the environment health policy and deaths due to air pollution categories. Also, India is ranked fifth in the world amongst top e-waste producing countries after the USA, China, Japan, and Germany and recycles less than 2 per cent of the total e-waste it produces annually formally. Since 2018, India generates more than two million tonnes of e-waste annually, and also imports huge amounts of e-waste from other countries around the world. Dumping in open dumpsites is a common sight which gives rise to issues such as groundwater contamination, poor health, and more. The Associated Chambers of Commerce and Industry of India (ASSOCHAM) and KPMG study, Electronic Waste Management in India identified that computer equipment account for almost 70 per cent of e-waste, followed by telecommunication equipment phones (12 per cent), electrical equipment (8 per cent), and medical equipment (7 per cent) with remaining from household e-waste. O e-waste in global context:- Despite 66 per cent of the world’s population being covered by e- waste legislation, only 20 per cent of global e-waste is recycled each year, which means that 40 million tonnes of e-waste is either burned for resource recovery or illegally traded and treated in a sub-standard way. The rate at which the e-waste volume is increasing globally is 5 per cent to 10 per cent yearly. In India, the volume of e-waste generated was 146,000 tonnes per year (Borthakur and Sinha, 2013). To safeguards the planet from toxic waste trade, the BAN, Silicon Valley Toxic Coalition (SVTC), and Electronics Take-Back Coalition (ETBC) constitute an associated network of environmental advocacy NGOs in the US. The three organizations’ common objective is to promote national-level solutions for hazardous waste management. O trial of toxic E-waste:- With the usage of electrical and electronic equipment (EEE) on the rise, the amount of electrical and electronic waste (e-waste) produced each day is equally growing enormously around the globe. Recycling of valuable elements contained in e-waste such as copper and gold has become a source of income mostly in the informal sector of developing or emerging industrialized countries. However, primitive recycling techniques such as burning cables for retaining the inherent copper expose both adult and child workers as well as their families to a range of hazardous substances

INTRODUCTION O AIM:- The toxic composition of E-waste and their effects on natural resources like soil & water in india,sri lanka,Bangladesh and Austrailia. O composition:- The electronic waste or e-waste describes discarded electrical or electronic devices. Used electronics which are destined for refurbishment, reuse, resale, salvage recycling through material recovery or disposal are also considered e-waste. Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution. O a brief history:- The world has come a long way since the technological revolution first started. From disposing of e-waste to recycling it, we have learnt how to deal with e-waste the hard way. After realising the true extent of harm caused by hazardous substances in e-waste, many rules have been introduced regarding the disposal and recycle of e-waste. The first step taken towards organising e-waste was the Resource Conservation and Recovery Act(RCRA), which was enacted in 1976 by the US government. This act led to the illegal dumping of e-waste in less developed countries. At this point, the rest of the world was just starting to grasp the consequences of such waste on their land. O what is e-waste ? The E-Waste is a term used to cover items of all types of electrical and electronic equipment (EEE) and its parts that have been discarded by the owner as waste without the intention of re-use. The term \"e-waste\" is an abbreviation of \"electronic and electrical waste\". A key part of the definition is the word \"waste\" and what it logically implies – that the item has no further use and is rejected as useless or excess to the owner in its current condition.

COMPOSITION:- Electronic waste or e-waste describes discarded electrical or electronic devices. Used electronics which are destined for refurbishment, reuse, resale, salvage recycling through material recovery, or disposal are also considered e-waste. Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution. A Brief History:- Electronic waste has been around for a very long time; however, the need for the proper disposal of that electronic waste began in the mid-70s. Soon thereafter the United States passed the Resource Conservation and Recovery Act (RCRA). This law made it illegal to dump electronic waste in the United States. This is when the recycling industry was formed and the proper disposing of and recycling electronic waste and old worn out electronic equipment of all kinds began. WHAT IS E-WASTE:- E-waste or electronic waste is created when an electronic product is discarded after the end of its useful life. The rapid expansion of technology and the consumption driven society results in the creation of a very large amount of e-waste in every minute.

E-WASTE GENERATION IN INDIA:- Despite the government’s emphasis on Swachh Bharat Abhiyaan and Smart Cities project, India continues to be generating highest e-waste vis-à-vis China, USA, Japan and Germany an ASSOCHAM-NEC recent study coinciding with the “Environment Day” noted. In India, Maharashtra contributes the largest e-waste of 19.8% but recycles only about 47,810 TPA (tonnes per annum) whereas as its counterparts Tamil Nadu (13%) recycles about 52,427, Uttar Pradesh (10.1%) recycles about 86,130, West Bengal (9.8%), Delhi (9.5%), Karnataka (8.9%), Gujarat (8.8%) and Madhya Pradesh (7.6%), the joint study noted. E-WASTE IN GLOBAL CONTEXT:- The European WEEE Directive classifies waste in ten categories: Large household appliances (including cooling and freezing appliances), Small household appliances, IT equipment (including monitors), Consumer electronics (including TVs), Lamps and Luminaires, Toys, Tools, Medical devices, Monitoring and control instruments and Automatic dispensers. These include used electronics which are destined for reuse, resale, salvage, recycling, or disposal as well as re-usables (working and repairable electronics) and secondary raw materials (copper, steel, plastic, etc.). The term \"waste\" is reserved for residue or material which is dumped by the buyer rather than recycled, including residue from reuse and recycling operations, because loads of surplus electronics are frequently commingled (good, recyclable, and non-recyclable). Several public policy advocates apply the term \"e-waste\" and \"e-scrap\" broadly to all surplus electronics. Cathode ray tubes (CRTs) are considered one of the hardest types to recycle. TRAIL OF TOXIC E-WASTE:-

E-waste is considered the “fastest-growing waste stream in the world”[8] with 44.7 million tonnes generated in 2016- equivalent to 4500 Eiffel towers.[4] In 2018, an estimated 50 million tonnes of e-waste was reported, thus the name ‘tsunami of e-waste’ given by the UN.[8] Its value is at least $62.5 billion annually.[8] Rapid changes in technology, changes in media (tapes, software, MP3), falling prices, and planned obsolescence have resulted in a fast-growing surplus of electronic waste around the globe. Technical solutions are available, but in most cases, a legal framework, a collection, logistics, and other services need to be implemented before a technical solution can be applied. Display units (CRT, LCD, LED monitors), processors (CPU, GPU, or APU chips), memory (DRAM or SRAM), and audio components have different useful lives. Processors are most frequently outdated (by software no longer being optimized) and are more likely to become \"e-waste\" while display units are most often replaced while working without repair attempts, due to changes in wealthy nation appetites for new display technology. This problem could potentially be solved with modular smartphones or Phonebloks. These types of phones are more durable and have the technology to change certain parts of the phone making them more environmentally friendly. Being able to simply replace the part of the phone that is broken will reduce e-waste. An estimated 50 million tons of Ewaste are produced each year. The USA discards 30 million computers each year and 100 million phones are disposed of in Europe each year. The Environmental Protection Agency estimates that only 15–20% of e-waste is recycled, the rest of these electronics go directly into landfills and incinerators. Growth of E- industries A short history:- The electronics industry emerged in the 20th century and is today one of the largest global industries. Contemporary society uses a vast array of electronic devices built in automated or semiautomated factories operated by the industry.

Environmental concerns and health hazards:- AIR:- Air pollution is a widespread problem in India—nine out of the ten most polluted cities on earth are in India. An important contributor to India's air pollution problem is widespread, improper recycling and disposal of e-waste. For example, dismantling and shredding of e- waste releases dust and particulates into the surrounding air. Low value e-waste products like plastics are often burned—this releases fine particles into the air that can travel hundreds-to-thousands of miles. Desoldering is a technique used to extract higher-value materials like gold and silver which can release chemicals and damaging fumes when done improperly. In addition to contributing to air pollution, these toxic e-waste particulates can contaminate water and soil. When it rains, particulates in the air are deposited back into the water and soil. Toxic e-waste air particulates easily spread throughout the environment by contaminating water and soil which can have damaging effects on the ecosystem.
