Austrian researchers find spent brewer's yeast can selectively capture metals from electronic waste, aiding recycling.

Austrian researchers have discovered that spent brewer's yeast, a byproduct of beer production, can be used to help recycle electronic waste in an eco-friendly and low-cost method. The spent yeast selectively captures metals from waste streams, aiding in the recycling process. This discovery could revolutionize waste management, as spent brewer's yeast has a natural affinity for metal ions, which are abundant in electronic waste.
