When we were kids, we thought one of the coolest science projects was powering a light bulb with nothing more than a potato. Since those science fairs, technology has advanced astronomically. We’ve come a long way from a simple light bulb as there is now an entire factory that’s powered by mashed potatoes.
England’s third-largest food company, 2 Sisters Food Group, uses leftover potato parts to power their plants. Potato fuel also includes peelings and mashed potato-based shepherd’s pies, reports The Guardian.
The potatoes are fed into a giant digestion plant that creates energy. Together, the discarded potato pieces are expected to generate 3,500 megawatt hours a year of electricity. That’s enough to power about 850 homes.
By using this method of energy production, 2 Sisters’ landfill output will drop to zero and its carbon emissions are reduced by a fifth. The company even plans to build ten more of these bio-refinery plants by the 2018. Four of which will focus on generating energy from chicken remains.
