摘要：
A process for treating used absorbent sanitary products, comprising the steps of providing a rotary cylindrical autoclave having an inner surface and two ends, at least one of which terminates in a hatch that can be opened to enable access to said autoclave and sealably closed to enable pressurization of said autoclave； loading said autoclave with closed absorbent sanitary products； heating and pressurizing the autoclave to a sterilization temperature and at the same time driving the autoclave in rotation about a longitudinal axis thereof, wherein said step of heating and pressurizing the autoclave envisages a first temperature regime for the products contained in the autoclave and a second temperature regime, higher than the first temperature regime, for said inner surface.
