The amount of the toxic waste generated in the hospitals and medical facilities is steadily increasing. Although, the centralized disposal or waste management service solutions for the removal of toxic waste are available in highly developed industrialized countries; this does not, however, apply to the developing and emerging countries. For this reason, a compact sterilization and shredding machine was developed. The steam sterilization used (temperatures of 134 °C + 4 K and pressures of 480 to 3500 mbar) complies with the recognized procedure of the Robert Koch Institute (without chemical substances). Thus, it was possible to transform the infectious or toxic waste into non-hazardous household waste. The microbiological and physical test results show that the machine meets the requirements for sterilization of class C solid and liquid clinical wastes. The capacity of the machine is maximum 400 liters of waste per cycle, with an average cycle time of about 1 hour. It is possible to process contaminated materials both loose and in sealed disposal containers (C-boxes).
