A method of processing excrement of mammals, fish, birds, reptiles, insects, and/or humans includes sterilizing the excrement to create a sterile fluid, adding one or more nutrients and adding microorganisms such as genus bacillus to the sterile fluid creating a processed fluid. The good microorganisms multiply and divide in the processed fluid, thereby reducing the growth of harmful or unwanted microorganisms in the processed fluid. The processed fluid is then, for example, released into waterways or used to water/fertilized crops.
