Boil them, mash them, stick them in a stew. Potatoes, as a hungry hobbit once noted, can be incredibly versatile. And now, in the north of England at least, they are being used as a source of energy.
The 2 Sisters Food Group – one of the UK's biggest food manufacturers – has just opened a new bio-refinery at its Carlisle food processing plant. The facility is powered by potato waste from the facility's pie and mashed potato manufacturing lines.
The plant won't be short of resources: the humble potato is used in roughly 10.14 billion meals every year, according to AHDB Potatoes, a division of the U.K.'s Agriculture and Horticulture Development Board.
