One of the U.K’s biggest food brands is going green this week by powering one if its factories not by wind or solar, but by potato. In an effort to reduce carbon emissions and eliminate food waste, 2 Sisters Food Group (parent company of some of the UK’s biggest food brands including Fox’s Biscuits and Goodfella’s pizzas) is implementing a new bio-refinery that uses potato waste from the factory’s mashed potato and pie manufacturing lines to generate energy. The bio-refinery is the first of its kind in the food industry. The food giant hopes to bring the technology to its other 42 factories.
