Experts estimate that by the end of 2021 year, people will send 57.4 million tons of electronics to landfills. This number of gadgets outweighs the heaviest artificial object – the Great Wall of China, BBC reports.
The global amount of electro-clutter increases by 3-4% or 2 million tons per year. This was reported by experts from the WEEE Forum, who prepared a report for October 14 – International Day of Electronic Waste.
According to their calculations, 57.4 million tons of gadgets and their spare parts will go to landfills in 2021. In terms of weight, this amount can be compared with the heaviest human structure – the Great Wall of China. By 2030, experts predict 74 million tons of electrical clutter.
According to the report, most of the discarded devices are not recycled but deposited in landfills or burned. At the same time, 1 million cell phones contain 24 kg of gold, 16 thousand kg of copper, 350 kg of silver and 14 kg of palladium. To ensure that these resources do not harm the environment, they must be extracted and returned to the production cycle. At the same time, it will reduce the carbon footprint, as 1 ton of e-waste is responsible for 2 tonnes of CO2.
The assessment is by an international expert group dedicated to tackling the global problem of waste electrical and electronic equipment (WEEE).
They point out that the value of those discarded materials is vast.
According to a 2019 report by the World Economic Forum, the world’s electronic waste has a material value of $62.5 billion (£46 billion) – more than the GDP of most countries.
“A tonne of discarded mobile phones is richer in gold than a tonne of gold ore,” said Dr Ruediger Kuehr, director of the UN’s Sustainable Cycles (SCYCLE) programme.
The waste includes items such as mobile phones, fridges, kettles, televisions and electric toys or sports equipment.
Stockpiling gadgets
Globally, the amount of so called e-waste generation is growing by two million tonnes every year. It is estimated that less than 20% is collected and recycled.
Pascal Leroy, who is director general of the expert group the WEEE Forum, says by making products with shorter lifespans and limited repair options, manufacturers have a major role to play in the increase of waste.
“Fast mobile phone development, for example, has led to a market dependency on rapid replacement of older devices,” he told BBC News.
Consumers can also be reluctant to recycle their personal electronic equipment. In the UK, a 2019 study by the Royal Society of Chemistry found that as many as 40 million unused gadgets are languishing in our homes. That puts pressure on the supply of many valuable and rare elements.
Elements in smartphones that could run out in the next century:
- Gallium: Used in medical thermometers, LEDs, solar panels, telescopes and has possible anti-cancer properties
- Arsenic: Used in fireworks, as a wood preserver
- Silver: Used in mirrors, reactive lenses that darken in sunlight, antibacterial clothing and gloves for use with touch-screens
- Indium: Used in transistors, microchips, fire-sprinkler systems, as a coating for ball-bearings in Formula One cars and solar panels
- Yttrium: Used in white LED lights, camera lenses and can be used to treat some cancers
- Tantalum: Used in surgical implants, electrodes for neon lights, turbine blades, rocket nozzles and nose caps for supersonic aircraft, hearing aids and pacemakers
“Consumers want to do the right thing but need to be adequately informed and a convenient infrastructure should be easily available to them so that disposing of e-waste correctly becomes the social norm,” added Pascal Leroy. He also pointed out that recycling electronics, rather than throwing them away, also reduces greenhouse gas emissions.
“Every tonne of WEEE recycled avoids around two tonnes of carbon dioxide emissions,” he said. “So this is more important than ever as our governments go into COP26 to discuss global action to reduce carbon emissions.”
