What To Do, What To Do About Gas From Livestock Poop

The cows and pigs dotting these flat green plains in the southern Netherlands create a bucolic landscape. But looked at through the lens of greenhouse gas accounting, they are living smokestacks, spewing methane emissions into the air.

That is why a group of farmers-turned-environmentalists here at a smelly but impeccably clean research farm have a new take on making a silk purse from a sow's ear: They cook manure from their 3,000 pigs to capture the methane trapped within it, and then use the gas to make electricity for the local power grid.
