The United States and China contributed most to record mountains of electronic waste such as cellphones, hair dryers and fridges in 2014 and less than a sixth ended up recycled worldwide, a UN study said on Sunday.
Overall, 41.8 million tonnes of “electronic recycling” — defined as any device with an electric cord or battery — were dumped around the globe in 2014 and only an estimated 6.5 million tonnes were taken for recycling, the United Nations University (UNU) said.
“Worldwide, electronic recycling constitutes a valuable “urban mine,” a large potential reservoir of recyclable materials,” said David Malone, the UN under secretary general and rector of UNU.
The report estimated that the discarded materials, including gold, silver, iron and copper, was worth some $52 billion.
The United States led electronic recycling dumping with 7.1 million tonnes in 2014, ahead of China with six million and followed by Japan, Germany and India, it said. Canada ranks lower on the list, in 15th place, with a dump of 725,000 tonnes.
The United States, where individual states run electronic recycling laws, reported collection of one million tonnes for 2012 while China said it collected 1.3 million tonnes of equipment such as TVs, refrigerators and laptops in 2013.
Norway led per capita waste generation, with 28.3 kg dumped per inhabitant, followed by Switzerland, Iceland, Denmark and Britain. On that ranking, the United States was ninth and China was not among a list of the top 40. Canada dumped 20.4 kg per capita.
Appliances add electronic recycling bulk
About 60 per cent of the waste was made up of items that included large and small appliances, vacuum cleaners, solar panels, video cameras and electric shavers.
Only seven per cent of the waste was made up of personal computers, printers, cellphones and similar equipment.
Researchers said in many cases it made economic sense to recover metals that included 16.5 million tonnes of iron, 1.9 million tonnes of copper as well as 300 tonnes of gold.
The gold alone was valued at $11.2 billion, with the precious metal used in devices because it is a good, non-corrosive conductor of electricity.
“At the same time, the hazardous content of electronic recycling constitute a ‘toxic mine’ that must be managed with extreme care,” said Malone, referring to components such as lead and mercury which are found on some discarded devices.
Global volumes of electronic recycling were likely to rise by more than 20 per cent to 50 million tonnes in 2018, driven by rising sales and shorter lifetimes of electronic equipment, the report said.
Ruediger Kuehr, one of the authors of the report, said many people were aware of the global problem of waste but often left aging toys or cellphones in drawers or cellars at home. “People don’t see it as an issue in their own households,” he said.
