Abstract


Microbial inactivation in organic waste is necessary to prevent environmental damage with impacts on vegetation and soil organisms. The objective of this research is process the organic sludge from poultry meats effluents in a microwave oven, aiming at microbial inactivation for its use as organic fertilizer. The sludge, previously dry at open-air, it was subjected to microwave action in the rotative cavity oven, ONDATEC® technology, at different temperatures and exposure time. Microbiological analysis was performed before and after treatment by the “Pour Plate” technique. The non-ionizing irradiation of the microwaves in the tested furnace is able to totally eliminate the CFU/g of the microorganisms present in the organic sludge from poultry slaughterhouse at 220ºC, it is showing process efficiency.


Keywords
