Cow power, using manure-fuelled tractors

Waitrose is currently the only UK supermarket to have its own farm; some 4,000 acres of property, farming, retail and leisure activities. It’s also the first UK retailer to use cow power to drive the tractors at its farm – or at least, harness the methane they create to do so.

The fully circular system takes the one thing beef and dairy farmers have more than enough of – manure – and turns it into renewable biomethane fuel, which can then be used to run specially-designed tractors which put out a fraction of the emissions of their petrol-powered equivalent.

The groundbreaking move of using its 500-strong herd of cows to help power the farming estate is an innovative step from Waitrose; one which remains firmly in line with with its commitment to achieving net-zero greenhouse gas emissions across its own operations by 2035.
