Scientists Use Cheese Byproduct to Extract Gold From E-waste

Electronic waste, abundant with valuable metals like copper, cobalt, and gold, presents an appealing opportunity for recovery amid increasing demand for precious metals. However, existing methods for gold extraction are often energy-intensive and reliant on hazardous chemicals. In the quest for sustainable solutions, a group of researchers led by Professor Raffaele Mezzenga from ETH Zurich’s Department of Health Sciences and Technology has devised a method to extract gold from electronic waste using a byproduct of the cheesemaking process.
