Method and device for the disinfection of waste

A process and apparatus for disinfection of waste in autoclaves by the fractional vacuum-steam process having atmospheric pressure steam phases, followed by a superatmospheric steam phase and a evacuation of the autoclave following each steam phase. The autoclaves are transportable separate from the remaining apparatus. In the evacuation after an atmospheric pressure steam phase, removing the atmosphere from the autoclave by suction, condensing the steam fraction and separating it as liquid having approximately ambient temperature. During evacuation after a superatmospheric pressure steam phase, first eliminating condensate from the lowest part of the autoclave, and feeding it to waste water at approximately ambient temperature. Evacuation following an atmospheric pressure steam phase is from an upper region of the autoclave, the atmosphere being then freed from micro-organisms. The steam is removed and gas fractions are freed from odorous substances and discharged to the environment. Evacuation after the superatmospheric pressure steam phase, after eliminating the condensate from the lowest point of the autoclave, is by removing the atmosphere by suction from the lower or upper region of the autoclave and freeing it from odorous substances prior to discharge into the environment. The device for eliminating the micro-organisms on charging the autoclave with process steam being connected to the autoclave and the atmosphere is removed from the autoclave by suction and freed from micro-organisms and solids by using filters.
