This will dramatically reduce the GHG production in the ethanol production process - expanding Wang's estimate of GHG reduction for corn based ethanol (17% - 24% lower than gasoline, depending on production process - wet-mill or dry-mill).
"Carter's "poop to pump" ethanol plant will fuel more than 90 percent of its own energy needs by heating up manure until it releases methane, which it will then burn to make steam to fuel the plant. The process destroys the methane, a greenhouse gas at least 20 times more potent than carbon dioxide.
Some environmentalists worry that runoff from farms that group large numbers of cattle together can pollute water supplies. But
Carter said the plant will turn what already exists in the region into something useful. Ash from the process can be used to make cow bedding and cement, he said.
Panda hopes to soon build another plant using the same technology in Kansas. The company expects to become publicly traded by the fall.
When it comes to harvesting manure, timing is important. "It can't be too fresh and it can't be too old," said Carter."
HEre's where David Pimentel could be a real help. IF THERE IS ANYBODY WHO KNOWS BULLSHIT, IT'S DAVID PIMENTEL. NOBODY PRODUCES IT MORE PROLIFICLY THAN MR. PIMENTEL.!!lol
