Potato power plant
2 Sisters started up a potato-powered energy plant to turn mashed potato and other factory waste into energy in September.
The bio-refinery generates energy and steam to help power the manufacturer’s chilled food factory in Carlisle, which mainly supplies Marks & Spencer.
2 Sisters sustainability director Andrew Edlin said: “The bio-refinery is a world-first for the food industry, using a new type of super-efficient technology to generate energy from potato waste.”
