Abstract: A process and apparatus for disinfection and reclamation of materials contained in contaminated disposable products worn by infants and adults containing human feces and/or urine. The process and apparatus disinfect, mechanically and biologically break down and separates these materials by the use of a pressurized steam digester, mechanical chopper and a screening process. The steam digester process is carried on in a sealed system utilizing a fume scrubber for controlling disposition of ammonia and methane gasses. Effluent and waste are controlled to maintain safe discharges and all recyclable materials are disinfected and reduced to a form suitable for remanufacture of like products or as raw materials for other manufactured products. Polymer particles are exposed to ultraviolet light for molecular breakdown and ion exchange between polymer chains, resulting in further reduction in mass of each particle.
