PURPOSE: To provide a waste treating device capable of safely and rapidly treating waste polluted by bacteria, virus, etc.

CONSTITUTION: This waste treating device is provided with a feed route 7 which moves the waste from a waste charge port to a prescribed pulverizing point, a pulverizing mechanism 10 which pulverizes the waste fed to the pulverizing point, a vibration generating mechanism 8 which moves the waste charged onto the feed route 7 in an aligned state to this pulverizing mechanism 10 by vibrating the feed route and a heating mechanism 19 which stores the pulverized matter pulverized by the pulverizing mechanism 10 and overheats the pulverized matter until the virus, etc., are killed. Further, the treating device is provided with a transporting mechanism 21 which transports the pulverized matter discharged from this heating mechanism 19 and a classifying means 30 which classifies the pulverized matter transported by this transporting mechanism 21 to plural kinds and charge the classified matter to prescribed housing bodies Ba, Bb.
