Abstract
Abstract A process which involves treating animal or poultry waste contained in a dropping pit or sedimentation tank of an animal or poultry confinement or holding pen with a sufficient amount of an acid to achieve and maintain the animal or poultry waste at a pH of about 4. Also, animal or poultry bedding material can be treated with acid (and after usage treated as above). The treatment eliminates the problems of the giving off of unhealthy gases and the growth of pathogens in the environment. The acid-treated waste material can be used as an animal feed or fertilizer ingredient.
