A process for pathogen reduction in waste where dewatered sludge having a solids content in the range of 10-60% is mixed with an additive selected from the group consisting of calcium oxide or calcium carbonate group. Hydration to calcium hydroxide occurs with an attendant release of heat. The pH of the sludge is then elevated and the heat of the hydration reaction is retained resulting in effective neutralization of pathogens. Apparatus is also disclosed.
