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 .
