A method of disinfecting medical materials, which comprises heating medical materials and exposing the medical materials to gamma radiation, is provided. One method of heating is the application of radio-frequency waves. The medical materials are subjected to radio-frequency waves for at least approximately 5 minutes and to gamma radiation measuring at least approximately 0.25 Mrads. When the starting material consists of pre-sorted medical or veterinary waste, the method further comprises shredding the irradiated waste and recycling the shredded waste.
