From Cow Farts to Protein Shakes: The Latest Climate ‘Solution’ Brewed in a Vat
15 hours ago Anthony Watts
Every few years, a new “breakthrough” arrives promising to upend agriculture as we know it. Lab-grown meat, insect protein, vertical farming—each comes with bold claims about saving the planet, feeding billions, and, conveniently, generating tidy profits along the way. Now we’re told that bacteria fed on methane—yes, the same gas routinely framed as a climate villain—can be turned into a superior protein source that outcompetes soybeans and fish meal on both environmental and economic grounds.
A recent press release tied to a peer-reviewed paper in Carbon Research makes precisely that claim. Engineers from Beijing University of Chemical Technology, led by Yanping Liu and Ziyi Yang, present a life-cycle assessment (LCA) comparing three protein supply chains: soybean meal, fish meal, and microbial protein derived from methane-oxidizing bacteria (MOB). Their conclusion is unambiguous: the microbial route wins—by a lot.
According to the release:
“Shifting to MOB protein shrinks overall ecosystem damage by 88% relative to standard soybean farming.”
