Summary
In Japan, recycling companies are converting discarded computers into valuable resources like gold and palladium, exemplifying the concept of urban mining. This initiative showcases the potential of e-waste as a significant resource in the country.
A significant recycling initiative based in Nagoya partners with 760 municipalities across the country, providing free collection of e-waste up to 20 kilograms. This collaboration leads to the annual collection of around one million discarded computers.
The recycling process includes manual disassembly and the use of advanced technology, such as AI, to identify and sort valuable electronic components. Connectors that contain high amounts of gold are particularly targeted during this process.
From one ton of computer circuit boards, over 10 grams of gold can be extracted, which is significantly more than the yield from natural gold mines. This highlights the efficiency of urban mining compared to traditional mining methods.
