Disinfection of waste can be carried out by first cutting the waste into
small pieces to expose surfaces in the waste and then simultaneously
spraying the waste pieces with disinfectant and agitating them. The waste
pieces are agitated by applying sufficient vacuum to suck the waste
pieces through a processing system, the vacuum creating a wind inside the
system that sweeps up the waste pieces, suspends them in air, and keeps
them separate from one another, thereby exposing substantially all
surfaces of the waste pieces to the sprayed disinfectant.
