  • Method and system for the treatment and utilization of waste products
    Patent number: 5527464
    Abstract: A method of handling the waste from a community begins with the collection of raw sewage and the separate collection of other bio-degradable solids. The raw sewage is separated into a liquid component and a sludge component. The sludge component of the sewage is combined with the bio-degradable solids in a single bio-mass and adjusted to a relatively dry bio-mass of at least 22-33 percent solids. Fermentated aerobically until a temperature of 60.degree.-65.degree. C. is reached, the ferment is then anaerobically fermentated to produce a high grade manure.
