If you look closely, you can see a faint yellow flame above our flare--that's biogas being burned off! We started adding fresh manure to the digester a week ago, and the bacteria have responded. Since our generator won't be cleared to deliver electricity until next week, we have to flare the biogas. This is already progress, though, since we're using manure that would otherwise be emitting methane in a lagoon; combusting that methane leaves much-less-potent carbon dioxide. Almost two and a half years after we first decided to test the carbon-offset business, we're finally starting to do our part.
