Incineration for treating infectious wastes
Controlled burning of wastes at high temperatures is called incineration and at CHAM this is carried out in a double chambered incinerator of 50kgs/hour capacity with fully equipped pollution control devices in accordance with the latest guidelines issued by the latest guidelines issued by the CPCB in September 2003.
Waste is burnt in the primary chamber at 800-850oC and volatile gases emitted are again burnt in the secondary chamber at 1050-1100oC (residence time of 2 seconds).
Maintenance of high temperatures as specified with immediate quenching with water is ensured through a PLC operated procedure to prevent formation of toxis gases such as dioxins and furans. The cycle time is of about 1 hour. The volume is significantly reduced with assured sterilization and destruction of microorganisms.

Shredder of the Autoclave Unit
Disinfected waste is automatically fed into the shredder, which mechanically mutilates the sterilized items of different categories into small unrecognizable pieces while being washed with hot water from the solar water heater to ensure shredding, cleaning to prevent re-infection and preventing particulate matter pollution.
The sterilized, cleaned and shredded waste is then stored before being sold for recycling.
