A Burning Answer for Manure: New system turns hog manure into dry fuel

摘要

Transforming manure into energy is hardly a new idea. People have been burning cow chips and chicken dung for centuries. Until recently, the best energy option for hog manure was capturing methane gas emissions from an anaerobic digester. But thanks to a project spearheaded by Envirogain, that's about to change. Dried hog manure can also serve as a good energy source. In fact, hog manure is as good a fuel as chicken manure mixed with wood chips, company officials proclaim.
