"Electronic waste" or "E-Waste" may be defined as discarded computers, office electronic equipment, entertainment device electronics, mobile phones, television sets, and refrigerators. This includes used electronics which are destined for reuse, resale, salvage, recycling, or disposal. Others are re-usables (working and repairable electronics) and secondary scrap (copper, steel, plastic, etc.) to be "commodities", and reserve the term "waste" 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" broadly to all surplus electronics. Cathode ray tubes (CRTs) are considered one of the hardest types to recycle.[3
Amount of electronic waste worldwide Edit
A fragment of discarded circuit board.
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 out-dated (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.[7] An estimated 50 million tons of E-waste are produced each year.[2] 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.[8][9]
Global trade issues Edit

Electronic waste is often exported to developing countries.
4.5-volt, D, C, AA, AAA, AAAA, A23, 9-volt, CR2032, and LR44 cells are all recyclable in most countries.
The E-waste centre of Agbogbloshie, Ghana, where electronic waste is burnt and disassembled with no safety or environmental considerations.
One theory is that increased regulation of electronic waste and concern over the environmental harm in nature economies creates an economic disincentive to remove residues prior to export. Critics of trade in used electronics maintain that it is still too easy for brokers calling themselves recyclers to export unscreened electronic waste to developing countries, such as China,[19] India and parts of Africa, thus avoiding the expense of removing items like bad cathode ray tubes (the processing of which is expensive and difficult). The developing countries have become toxic dump yards of e-waste. Proponents of international trade point to the success of fair trade programs in other industries, where cooperation has led to creation of sustainable jobs and can bring affordable technology in countries where repair and reuse rates are higher.

As we are becoming more modern and industrial day by day.We are constantly harming and polluting our mother nature.
Generation of huge amount of waste materials is the major bad effect of the industrialization.
E-waste are the most modern types of waste materials.E-waste are actually broken and damaged electronic equipments and accessories which we throw in the garbage.
This e-waste are mainly made from the non-biodegradable materials like plastic,which doesn't decomposes in the soil and contaminates the environment.
We have to recycle and reuse the e-waste to prevent the toxic contamination from it.
