Hospital wastes have always been considered as potentially hazardous in view of   the inherent potential for dissemination of infection. The major identified hazard   was that of infection, because over millennia communicable diseases had been   the most common cause of morbidity and mortality in the community and   majority of persons receiving treatment in the hospitals were suffering from       communicable diseases. Disinfecting right at source and disposal by incineration,   which completely destroys micro-organism of all types, has been the time tested   and most widely advocated method for safe management of hospital waste.
