"In 2022, humans produced an estimated 62 million tonnes of electronic waste –
enough to fill more than 1.5 million garbage trucks. This was up 82% from 2010
and is expected to rise to 82 million tonnes in 2030.
This e-waste includes old laptops and phones, which contain precious materials
such as gold. Less than one quarter of it is properly collected and recycled.
But a new technique colleagues and I have developed to safely and sustainably
extract gold from e-waste could help change that.
Our new gold-extraction technique, which we describe in a new paper published
today in
Nature Sustainability, could also make small-scale gold mining less
poisonous for people – and the planet."
