Scientists Extract Real Gold From Old Tech Using Cheese Waste

Scientists at ETH Zurich developed a special material made from whey protein and amyloid aerogel. This sponge like creation can pull gold ions directly out of acid dissolved computer parts. During lab tests, the team successfully recovered a solid gold nugget from twenty old computer motherboards. The final result was high purity twenty two carat gold.

This discovery offers a smart way to recycle electronic waste while putting dairy industry leftovers to good use. Millions of old computers and phones sit in drawers around the world. Turning cheese manufacturing byproducts into a tool for metal recovery makes the recycling process much cheaper and greener.

Traders and environmental watchers will want to keep an eye on how this technology scales up. If tech recycling companies adopt this method, recovering precious metals from e waste could become a major commercial industry. That means less toxic waste and a steady new supply of recovered gold entering the market.
