Our growing reliance on technology at home and in the workplace has raised the profile of e-waste. This consists of discarded electrical devices including laptops, smartphones, televisions, computer servers, washing machines, medical equipment, games consoles and much more.
The amount of e-waste produced this decade could reach as much as 5 million metric tonnes, according to recent research published in Nature. This is around 1,000 times more e-waste than was produced in 2023.
According to the study, the boom in artificial intelligence will significantly contribute to this e-waste problem, because AI requires lots of computing power and storage. It will, among other things, lead to more turnover of computer servers used in the data centres that support the extra computational needs of AI systems.
This rising tide of e-waste, coupled with the limited lifetimes of hi-tech devices, could affect global sustainability goals.
E-waste contain toxic and hazardous substances such as mercury, which can pose serious risks to human health and the environment. E-waste is among the fastest-growing types of solid waste globally: more than 5 billion mobile phones are thrown away each year, according to the Waste Electrical and Electronic Equipment forum.
In 2022, e-waste reached a record 62 million tonnes – an 82% increase since 2010 – and accounted for 70% of total global waste. However, less than 20% is formally recycled.
Data centres and transmission networks are responsible for more than 1% of global........
