Gold in Them Plastic Hills

 


Not before time, the UK is due to get its first plant in Cheshire to extract precious metals (largely gold and platinum) from electronic waste which is termed 'e-waste' (https://www.theguardian.com/environment/2020/aug/22/britain-first-commercial-refinery-extracting-precious-metals-e-waste-mint-innovation). The plant will be a startup from Mint Innovations (a New Zealand group) and will be the first to use a bacteria-based process, rather than the more typical cyanide-based technique. The startup is necessary as the UK is unlikely to have access to extraction facilities in Europe after Brexit. A UN report noted that 54 million tonnes of e-waste was generated world-wide in 2019 (this is growing at 3 times the speed of the world's human population). Much of this waste is not recycled (it's relatively difficult, given the mixture of materials).  The UN report estimated, however, that almost £8 billion pounds worth of precious metals could be extracted (and reused) annually from e-waste. It seems silly just to throw it away! Having said that, it was earlier noted that one can extract precious metals from human faeces.
