Green Cell Technologies (GCT) and RWH Holdings (RWH) have worked with several global brewers over a period of eight years to understand the challenges around what to do with their leftovers—brewers spent grain (BSG) and brewers spent yeast (BSY)—and the answer, as it would happen, is disrupt it.

About 39 million tons of brewer’s spent grain (BSG) is produced annually worldwide. That is the same as approximately 3,900,000 waste removal trucks which, end-to-end will wrap around Earth’s equator 6.8 times. BSG is the residual waste stream that remains after the brewing of beer. BSG is remarkably high in protein and fiber, has some residual energy and is a healthy food intake for human, animal and earth—if prepared correctly.
