The Greek yogurt boom has taken the nation by storm. And while many enjoy the dairy product for its unique, flavorful taste, others are finding it to be a delicious means to produce electricity. Yes, believe it or not, the waste byproduct of yogurt production called whey is now being used by yogurt producers to offset their electricity bills. They do this by shipping the whey – which is a gooey, non-toxic substance – to an anaerobic digester to be converted to methane. Once converted, it can be burned to produce electricity to power a factory. In one case, an upstate New York company was able to shave over a half-million dollars off its electricity bill – a savings which certainly stirs in nicely with yogurt producers.
