One of the UK’s biggest food manufacturers is turning to the power of the potato as it seeks new sources of energy to run its factory. 2 Sisters Food Group has installed a plant that allows surplus mash from its production line to be converted into electricity and heat, in a move that should cut carbon emissions by a fifth. The anaerobic digestion plant takes peelings and unused potato that would otherwise go to waste. 2 Sisters claims its facility in Carlisle, England should produce 3,500 megawatt hours per year of electricity or enough to power around 850 homes. It’s also expected to generate a further 5,000 megawatt hours per year in heat for the plant’s manufacturing processes.
