Process Turns Cow Waste into Usable Gas
Seven-year-old James Hoare is the future of his family farm in England, and one of his jobs is shoveling the farm's future... in the form of cow poo in the barn.
"It's a form of liquid gold, isn't it?" said his mother Katie Hoare, who helps run the rented operation. "Because you can't do much without the slurry, it's an incredible form of fertilizer."
The "slurry," better known as liquid cow patties, is powering the farm. Once collected, the cow waste is pumped into a lagoon where the harmful methane is captured, instead of leaking into the atmosphere. Two tarps cover the lagoon, first collecting the raw methane released from the cow waste. It's then processed and pumped under a second tarp for storage to produce gas.
