Researchers at ETH Zurich have developed a groundbreaking method to extract gold from old motherboards using food waste byproduct, specifically whey from the cheesemaking industry. The process involves creating a sponge from whey to collect gold from e-waste in an acid bath, followed by high heat to form nuggets. The value of the extracted gold is 50 times more than the cost of the process, making it commercially viable and environmentally sustainable. This innovative technique offers a more sustainable and profitable alternative to current methods, contributing to e-waste recycling and potentially making electronic devices more affordable for consumers.

Researchers have proposed using protein amyloid aerogels, derived from food waste protein like whey, to optimize the recovery of precious metals such as gold from electronic waste. These aerogels, with their high surface area for adsorption, demonstrated an impressive 93.3% efficiency in gold recovery while leaving other metals mostly untouched in the solution. The chelation properties of the protein amyloids make them effective at bonding to metal ions, offering a potential cost-effective and environmentally friendly approach to e-waste recycling.
