Recycling Spent Yeast
Is Recycling Yeast an Option? asks Erin Voegele in her article at Ethanol Producer. Sure lots of yeast must eventually be disposed of in the brewing industry, but with the growth of fermentation to produce ethanol fuel, it could become more of a disposal problem.
An excerpt: “Sugarcane ethanol producers typically recycle the yeast used in their fermentation process. While yeast recycling can offer a variety of benefits, it can also introduce problems with contamination and shift a plant’s fermentation profile.”
It’s an in-depth article that’s well worth reading.
