After Brewing Beer, Yeast Can Help Recycle Metals from E-waste


Recommended Posts


When brewer’s yeast left over from beer making is mixed with the right seasonings, it makes a bitter, earthy paste called Marmite that is especially popular in the U.K. Smeared on toast, it’s a snack that can be an acquired taste. But a study published recently in Frontiers in Bioengineering and Biotechnology found that re­­­sidual yeast sludge can also be used to bind to electronic-waste metals—a capa­­bil­ity the research suggests could help recycle the world’s growing mountains of discarded gadgets.

As a one time sampler I wonder does one do that before they spread it on bread to improve the flavor?:D  Seriously, good article.  Thanks.
