UK gets its 1st bio-refinery, recovering precious metals from e-waste without cyanide

Brexit has introduced the potential for higher costs for e-waste recovery in the UK. A NZ start-up thinks they have a "micro-brewery" style, localised solution. Their process uses a bio-refinery process that combines hydrometallurgy and biotechnology to safely extract metals – including gold, palladium, silver and copper – from e-waste.

The process removes the need for the use of cyanide in the recovery process, although other lower level chemicals are still needed. Initial plans include 2 units in the UK and 1 in Sydney, Australia.
