Trashed electric devices pile up despite recycling
UN agencies have warned that waste from electronics is piling up worldwide while recycling rates remain low and are likely to fall even further.
The agencies were referring to “ewaste,” which is defined as discarded devices with a plug or battery, including cellphones, electronic toys, TVs, microwave ovens, e-cigarettes, laptop computers and solar panels. It does not include waste from electronic vehicles, which fall into a separate category.
In a report released this week, the UN’s International Telecommunications Union and research arm said some 62 million tons of “ewaste” was generated in 2022, enough to fill tractor-trailers that could be lined up bumper to bumper around the globe. It’s on track to reach 82 million tons by 2030.
Metals — including copper, gold and iron — made up half of the 62 million tons, worth a total of some $91 billion (U.S.), the report said. Plastics accounted for 17 million tons and the remaining 14 million tons include substances like composite materials and glass.
The UN says 22 per cent of the e-waste mass was properly collected and recycled in 2022. It is expected to fall to 20 per cent by the end of the decade because of “staggering growth” due to higher consumption, limited repair options, shorter product life cycles, growing “electronification” of society, and inadequate e-waste management infrastructure, the agencies said.
They said some of the discarded electronic devices contained hazardous elements like mercury, as well as rare earth metals coveted by tech industry manufacturers. Currently, only one per cent of the demand for the 17 minerals that make up the rare metals is met through recycling.
About half of all e-waste is generated in Asia, where few countries have laws on e-waste or collection targets, according to the report. In Africa, which generates the least of any of the five big global regions, recycling and collection rates hover at about one per cent, it said.
