The Royal Mint has signed an agreement with Canadian start-up Excir to recover 99% and more of gold from devices’ circuit boards. It said the chemistry selectively targets and extracts precious metals from circuit boards in seconds. Initial use of the technology at the Royal Mint has already produced gold with a purity of 999.9, but when fully scaled up it has potential to also recover palladium, silver and copper. If nothing is done to counter the problem, electronic waste is set to reach 74 million tonnes by 2030 – almost a doubling of tonnage in a decade, the mint said. Can the whole gadget be recycled to counter waste problem ?
