Developing beer technology

The beer brewing process wastes massive amounts of water. In Japan, it takes ten liters of water to brew one liter of beer. Brewing also requires huge supplies of grain. China imports more than 16 million tons of grain each year just to make beer and alcohol – more than it imports for people. But the fermentation process extracts only 8% of the nutrients in the grain. Of the nutrients left behind, 26% is pure protein.
