Bacteria helping to extract rare metals from old batteries in boost for green tech

Team at University of Edinburgh using microbes to recycle lithium, cobalt and other expensive minerals

Scientists have formed an unusual new alliance in their fight against climate change. They are using bacteria to help them extract rare metals vital in the development of green technology. Without the help of these microbes, we could run out of raw materials to build turbines, electric cars and solar panels, they say.

The work is being spearheaded by scientists at the University of Edinburgh and aims to use bacteria that can extract lithium, cobalt, manganese and other minerals from old batteries and discarded electronic equipment. These scarce and expensive metals are vital for making electric cars and other devices upon which green technology devices depend, a point stressed by Professor Louise Horsfall, chair of sustainable biotechnology at Edinburgh.
