Scientists have discovered an innovative, eco-friendly method of extracting gold from electronic waste (e-waste) using whey protein sponges, a dairy byproduct. This groundbreaking process is not only 50 times less expensive than the cost of gold but also significantly reduces the energy demands of recycling plants. The research team was led by scientist Raffaele Mezzenga from the Department of Health Sciences and Technology, ETH Zurich.
