Amount of electronic waste worldwide Edit

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 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.[9] An estimated 50 million tons of E-waste are produced each year.[10] 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.[11][12]

In 2006, the United Nations estimated the amount of worldwide electronic waste discarded each year to be 50 million metric tons.[13] According to a report by UNEP titled, "Recycling – from E-Waste to Resources," the amount of e-waste being produced – including mobile phones and computers – could rise by as much as 500 percent over the next decade in some countries, such as India.[14] The United States is the world leader in producing electronic waste, tossing away about 3 million tons each year.[15] China already produces about 2.3 million tons (2010 estimate) domestically, second only to the United States. And, despite having banned e-waste imports. China remains a major e-waste dumping ground for developed countries
