And A machine to carry out the method, comprising a front chamber for the entrance of the material; a contiguous rear chamber associated with the entrance chamber, by means of which the processed material is expelled; said contiguous rear chamber containing a grinding means that rotates when it is actuated by an engine; and a piston that enters into the front chamber running along said chamber into the rear chamber until it reaches a grinding means, where the grinding means consists of a solid, hard and heavy cylinder associated with a transverse axis, said cylinder being provided with a set of longitudinal slots from base to base that form edges with the cylinder surface. ## Claims ### Claim 1 A method for the reduction and/or removal of pathogenic agents and microorganisms contained in solids, comprising the following steps: a) providing a front chamber for the entrance of the starting material; a contiguous rear chamber associated with the entrance chamber, by means of which the processed material is expelled; said contiguous rear chamber containing a grinding means that rotates when it is actuated by an engine; and a piston that enters into the front chamber running along said chamber into the rear chamber until it reaches a grinding means, where the grinding means consists of a solid, hard and heavy cylinder associated with a transverse axis, said cylinder being provided with a set of longitudinal slots from base to base that form edges with the cylinder surface, where the light existing between the solid cylinder and the drum containing it is smaller than 5 mm, b) Purification of the starting material to dispose of materials that combine a size over 10 cm3 and hardness similar to boulder or paving stone and malleability as metal, c) Adjustment of the humidity degree of the material obtained in step b), d) Grinding and heating and pressurizing simultaneously the material obtained in step c), where the grinding and heating and pressurizing of step d) are carried out simultaneously by grinding the material until the material is powdered; and by means of friction of the powdered material between the light existing between the solid cylinder rotating and the drum containing it, plus the pressure of the piston advancing towards the grinding cylinder, heating and pressurizing is obtained, thus converting water into steam until the desired temperature is reached. ### Claim 2 (depends on 1) The method of claim 1, comprising that the simultaneous grinding and heating process is carried out in an operating pressure range between 3 kg/cm2 and 7 kg/cm2. ### Claim 3 (depends on 2) The method of claim 2, comprising that the material heating target temperature is in the range from 72° C. to 138° C. ### Claim 4 (depends on 3) The method of claim 3, comprising that the time during which the material is subjected to the target temperature is in the range from 1 second to 3 minutes. ### Claim 5 (depends on 4) The method of claim 4, comprising that the time during which the material is subjected to a temperature in the range from 72° C. to 91° C. is within a range between 3 and 15 seconds. ### Claim 6 (depends on 4) The method of claim 4, comprising that the time during which the material is subjected to a temperature in the range from 92° C. to 138° C. is within a range between 5 and 20 seconds. ### Claim 7 (depends on 4) The method of claim 4, comprising that the time during which the material is subjected to a temperature in the range from 115° C. to 136° C. is within a range between 21 seconds and 3 minutes.
