ABSTRACT:
A method for preparing fertilizer from animal, human and medical waste utilizing vacuumized microwave pathogen decontamination. The invention contemplates simultaneously heating the waste and reducing the pressure the reaction chamber in which the waste is located. As a result of the invention, the waste is decontaminated at a low temperature and the nutrients are preserved. The decontaminated waste is then mixed with a planting medium such as soil. The method may also include adding a diluting substance, chosen from the group consisting of humate, sawdust and sand, to dilute the nitrogen content of the disinfected waste.
