Abstract
To investigate the dryer performance for treatment of infectious hospital waste (IHW), drying kinetics, volume, and microbiological load reduction characteristics were studied. A surrogate waste and B. subtilis (BSN) were used for effectiveness testing of the drying. Satisfactory performance was found for microbiological load reduction. The study of a thermal inactivation kinetics of the BSN shows that a reduction of 6 orders of magnitude occurred in 42 min. The volume reduction obtained was equal to 30–50% after drying. The results obtained were comparable to results from IHW treatment technologies currently in operation.
