Abstract: A process for treating animal and plant waste includes chemical treatment to deodorize the waste and kill bacteria, to obtain a desired nutritional balance, and to ensure desired product properties. The treated waste is also treated to inactivate seeds, and hammermilled for physical and chemical consistency. The material is sized and formed into a final product that can be further treated or used as such. The material can also be treated with microbial agents, sterilized by thermophilic anaerobial and thermal means. Configuration of the process steps can be varied over a considerable range.
