Your cow muck can make money for you

“A dairy farmer is making more money using the slurry produced by his cows for energy production than he is by selling their milk,” according to a BBC report.
David Metcalfe, from Leyburn, North Yorkshire, UK said the milk produce by the cows is fast losing market and has however found gold from the animals.
“The milk is losing money, the slurry [made from cow dung] is making money,” he told the BBC.
The report says the dairy farmers “cow muck is scraped off, piped into an anaerobic digester and broken down by bacteria to produce methane gas.”
The gas produced by the cow dung is then used to generate electricity, which he supplies the power to his farm and also sold into the National Grid.
According to the farmer, each of his cows produces average of 33 litres of milk a day, or 10,000 litres a year, with current milk prices ranging between 23 British pence  and 25 pence.
Mr. Metcalfe stated that the 900 cows he has, give him about 100 tonnes of slurry per day.
“That electricity that is produced cuts the farm’s power costs by 60%,” the report noted.
The farmer said that the economic potentials of the business look viable, adding that “it’s given us another angle to our business.”
A part from the electricity generation, the processed slurry is re-used as a fertiliser, which could be sold to crop farmers.
