A kitchen waste processor includes a base including a basket which has a heater located therein. A driver rotates the basket which is pivotably supported by a support. A container is located in the basket and protrudes beyond the open top of the basket. A cover has a hole defined centrally therethrough, and a seal is located within the hole. A vacuum suction pipe or a blade shaft extends through the hole. A locking device is located between the container and the cover to seal the cover to the container. The container receives kitchen waste and bacteria therein. The heater heats the container while the container is driven by the driver to spin, so that the kitchen waste in the container is fermented under high temperature to transfer the kitchen waste into fertilizer.

The present invention relate to a waste mask treatment device using a sterilizing material, and more particularly, to a waste mask treatment device including: a body with an inlet adapted to insert a waste mask thereinto; a pulverization part located inside the body to pulverize the waste mask into pieces of mask; a sterilization part for emitting a sterilizing material for sterilizing the pieces of mask; and a collection part for collecting the pieces of mask. Accordingly, the waste mask treatment device is capable of being conveniently movable, being compact in size, and eliminating more than 99.99% of harmful bacteria living on the disposable mask through the sterilizing material.
