Leveling up your bowl of curds and whey (also known as cottage cheese!) makes protein fibril sponges that collect gold from an acid bath containing e-waste.
An efficient e-waste recycling process is made possible by whey, a byproduct of cheesemaking.
Scientists in Switzerland have recovered high-purity gold through a scalable process using food scrap-derived sponges that efficiently adsorb the precious metal from tricky e-waste.
The final result is 450 milligrams of 22-carat gold recovered from 20 discarded motherboards.
