Powering homes with manure could solve Britain's energy crisis.
Manure could power houses in Britain
The dairy company Arla has urged the UK government to tap into the unused source of energy from farms and the wider food supply chain.
Figures show that almost 91 million tonnes of manure and slurry could be turned into eight billion cubic metres of biomethane - enough to heat 6.4 million homes across the country.
James Pirie, vice president of UK logistics for Arla, said: "At a time when energy security is a major concern for the government, businesses, and households across the UK, we're clear about the opportunity presented by waste from farming and the wider food industry.
"We've shown that 'poo power' is a viable and reliable source of power - so we're calling for the Government to support British farmers, and the waste and energy sectors, with their plans for investment in infrastructure."
