Cheese energy could power hundreds of UK homes

The Wensleydale Creamery makes one of England's best-loved varieties of cheese, but it also produces waste.
Now, the bi-products are being put to use creating biogas – the latest evidence of the growing role of cheese in green energy production.

The North Yorkshire company will supply whey to a local biogas plant. The facility already uses waste ice-cream to produce gas by anaerobic digestion. The company says the gas from the whey will generate 10,000 MWh of thermal power, enough to heat 800 homes per year.
Further north, in Cumbria, farmer-owned cheesemaker First Milk has its own plant that uses whey to produce biogas.
Electricity from cheese
France, home to countless cheeses – from 50 holders of the prestigious official Appellation d’origine protégée status to local farm-made varieties – has a cheese-powered electricity-generating plant supplying 1,500 homes in Albertville in the Alps.
Whey produced by cheesemaking has similarly been used in anaerobic digesters making biogas in other countries, including Italy, Canada, Mexico, the US and New Zealand.
Prince Charles, the heir to the British throne, is said to be a convert to cheese power. His Aston Martin has been adapted to run on biofuel which, UK media have noted, can be generated from leftover cheese and wine.

The royal fuel is supplied by Green Fuels, a UK firm that says it has installed biodiesel plants in more than 50 countries including Mexico, Bali and the US. The US is the world’s largest producer of biofuels, mostly bioethanol from corn.

Green Innovation is spreading across all industries and now cheese is entering the energy space.
'The bi-products are being put to use creating biogas – the latest evidence of the growing role of cheese in green energy production'
From France to the UK to Argentina, more counties are realising the potential for a more circular approach to cheese production (so many circular puns to be made)
In Argentina alone it is estimated the country’s cheese industry generates 9 million tonnes of whey each year, two-thirds of which is discarded and can instead be used for energy production.
Anaerobic digestion and biogas could play an important role in creating a circular economy...
