Beer PowerA New Zealand brewery is experimenting with beer power, and has created a new product called Brewtoleum. This is a biofuel made of inactive yeast that is leftover⁶ during the brewing⁷ process. The slurry is sometimes sold to farmers to use in livestock⁸ feed, though it is often disposed of as waste. While many believe Brewtoleum is simply a publicity stunt, others say the brewery is on the right track. Beer grain waste is becoming a big problem in many European countries. New restrictions⁹ prevent many breweries¹⁰ from selling beer waste to farmers. Though beer-powered cars may not be realistic, converting beer waste to biofuel for the purpose of powering breweries is actually feasible.
