Disinfection of waste can be carried out by applying sufficient vacuum to suck 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.

1. A system for disinfecting waste, the system comprising: a trough that receives waste pieces and that comprises one or more disinfectant inlets;a source of disinfectant that is in fluid communication with the one or more disinfectant inlets to spray onto the waste pieces a liquid disinfectant that kills pathogens on contact; anda circulation system that applies sufficient vacuum through the trough to suck waste therethrough, agitate the waste pieces, and sweep the waste pieces up in a wind that suspends the waste pieces and keeps the waste pieces separate from one another as the waste pieces are being sprayed with the disinfectant, thereby exposing substantially all surfaces of the waste pieces to the disinfectant, coating the waste pieces with disinfectant, and disinfecting the waste pieces. 2. The system of claim 1, further comprising a loading chamber into which uncut waste is received. 3. The system of claim 2, wherein the loading chamber comprises an outer door and an inner door, the outer door transitionable between an open state to allow loading of waste into the loading chamber and a closed state to seal waste within the system, and the inner door transitionable between a closed state to provide a surface in the loading chamber and an open state allowing waste to advance from the loading chamber. 4. The system of claim 3, wherein the inner door and the outer door are interlocked with one another so that only one of them may be in an open state at a given time. 5. The system of claim 1, further comprising a wetting tunnel that receives disinfectant-sprayed waste pieces from the trough and extends upward from the trough, wherein the waste pieces are agitated in the wetting tunnel by operation of the circulation system, and wherein the circulation system provides sufficient vacuum to overcome gravity to ensure that the waste pieces pass through the wetting tunnel without falling back to the trough. 6. The system of claim 5, further comprising a separator positioned to receive waste from the wetting tunnel. 7. The system of claim 6, wherein the separator comprises a cyclone separator, and wherein the system further comprises (a) a receiving bin positioned to receive bulk waste pieces, and (b) a filter to trap particulate matter from the cyclone separator. 8. The system of claim 2, wherein the circulation system applies the vacuum to the loading chamber. 9. The system of claim 2, wherein the loading chamber comprises a door transitionable between a loading state to provide a surface in the loading chamber on which to place waste, and a sealed state to seal waste within the system. 10. A method of disinfecting waste, comprising simultaneously: introducing infected waste pieces into the trough of the system of claim 1;agitating infected waste pieces by applying sufficient vacuum to sweep the infected waste pieces up in a wind that suspends the infected waste pieces and keeps the infected waste pieces separate from one another, thereby exposing substantially all surfaces of the infected waste pieces to a sprayed disinfectant; andspraying the waste pieces with a liquid disinfectant that kills pathogens on contact, thereby coating the waste pieces with disinfectant and disinfecting them. 11. The method of claim 10, further comprising cutting infected waste into the infected waste pieces having cross sections no larger than one square inch, thereby exposing surfaces of the waste, prior to introducing. 12. The method of claim 10, wherein the system further comprises a wetting tunnel that receives disinfectant-sprayed waste pieces from the trough, and wherein the waste pieces are agitated in the wetting tunnel. 13. The method of claim 12, wherein the wetting tunnel comprises one or more disinfectant inlets to spray disinfectant onto waste pieces in the wetting tunnel, and the method further comprises spraying the waste pieces with a disinfectant while the waste pieces are agitated in the wetting tunnel. 14. The method of claim 10, wherein the disinfectant comprises an alkaline solution. 15. The method of claim 14, wherein the alkaline solution is prepared using kiln dust. 16. The method of claim 15, wherein the alkaline solution has a pH of 12 or greater. 17. The method of claim 14, wherein the alkaline solution comprises a 10% aqueous solution of calcium oxide. 18. The method of claim 10, wherein the disinfectant is provided in dry powder form and mixed with water to form an aqueous solution shortly before being sprayed onto the waste pieces. 19. The method of claim 10, wherein the steps are carried out without adding heat to the waste processing system, without removing heat from the waste processing system, and without increasing pressure inside the waste processing system.
