Would you eat industrial byproducts? One food tech company from Estonia certainly hopes so. Think about sawdust. Eating it is probably the last thing that comes into your mind, but that may be about to change. ÄIO, set up in 2022, has created a way of producing fats and oils from industrial waste “What we have developed is very similar to brewing beer, where yeast is used to convert sugars from barley into alcohol, and hops are added for taste,” Petri-Jaan Lahtvee said. “We are using a different type of yeast that coverts sugars from industrial sidestreams, but not into ethanol – into fats and oils instead,” he added. …Timber, agricultural byproducts like straw, and even food waste, can be turned into ingredients for the food or cosmetic industries.
