Treatment Options at CHAMP CTF

Treatment at the CTF site, Gulbarga is being done as per the Schedule 1 of Rule 5 of Biomedical Waste (Management and Handling) Rules, 1998.

To ensure the efficacy of the treatment, the project has been aiming at achieving 100 % segregation of waste at the source level.

The various treatment technologies engaged at the CHAMP CTF are…..

Feb 2010

Incinerator (1 in no.) of capacity 50 kgs /hr for treatment of waste under categories* 1,2

Modified Autoclaves (2 in no) each of capacity 100kg/hr for treatment of waste under categories* 3,4,6,7

Metal Sharps Manager (1 in no) of capacity 10 kg/hr for treatment for metal sharps

Land filling for rejects, incinerator ash and hazardous chemicals categories 5 and 9 & solid part of category 10

Deep Burial as a stand-by option in case of breakdown or maintenance of incinerator at the site

ETP for the liquid waste generated at the site of category 10

* The various categories of the biomedical waste as classified in the BMWM Rules 1998 explained in the subsequent slides

Feb 2010

Onsite Cold Storage Facility

The CTF has on site cold storage facility where the biomedical waste after collection and transportation from the HCEs is kept till the time of treatment

Feb 2010

Incineration at the CHAMP CTF The burning of wastes at high temperatures, under controlled

conditions, is called incineration and this is carried out in a double-chambered device known as an incinerator

Waste is burnt in the primary chamber at 800-8500C and volatile gases emitted are again burnt in the secondary chamber at 1050 -11000C (residence time - at least 2 sec).

The incinerator at the CHAMP CTF is retrofitted with the High Pressure Venturi Scrubber, as air pollution control device. The equipment also has the facility of computer recording for CO, CO2 and O2 in gaseous emission of critical parameters.

The cycle time for the entire operation is about 1 hour. The volume is significantly reduced with assured sterilization and destruction.

The equipment follows all the latest specifications and guidelines specified by the CPCB in Sept 2003 for the Common Facility Incinerators

The equipment is used for the treatment of waste falling under Category 1,2 of BMWM Rules which consists of ……

Feb 2010

Incinerable Waste

Category 1– Human Anatomical Waste

(human tissues, organs, body parts)

Category 2– Animal Waste (animal tissues, organs, body parts, carcasses,

bleeding parts, fluid, blood and experimental animals used in research, waste generated by veterinary hospitals, colleges, discharge from hospitals, animal houses)

The category 1 and 2 waste are stored in yellow liners which have to be non chlorinated so as to minimize the chances of emission of dioxins and furans, major pollutants having carcinogenic properties

50 Kg / hr capacity Incinerator at the CHAMP site

Feb 2010

Deep Burial at the CTF Site

Deep Burial is the stand-by option in case of the failure of incinerator operation for Category 1 and 2 Infectious waste

Infectious Waste belonging to Category 6 (soiled cotton, dressings etc.) is also disposed of in deep burial after sterilization in the modified autoclave

Feb 2010

Autoclaving at the CHAMP CTF site Steam is applied inside a double-walled jacket under pressure. Waste is fed into the chamber where it gets hydrated, agitated &

sterilised The waste is internally fragmented to attain a high level of sterilization. Steam sterilization followed by dehydration, results in dry waste, greatly

reduced in weight and volume The sterilized waste is then shredded in the shredding assembly fitted

below the autoclave system. Along with the shredding, hot water washing also takes place in the

shredder, making the sterilized and shredded waste suitable for recycling

The salient feature of the modified autoclave system at CHAMP CTF site is that the solar water heater which supplies hot water for steam, which ensures energy efficiency and reduces the cost of operation by reducing diesel / electrical consumption for producing steam

Autoclaving is used to treat waste falling under the category 3, 6 and 7.

Feb 2010

Sterilizable Waste

Category 3 –Microbiology & Biotechnology waste (wastes from laboratory cultures, stocks or specimens of micro organisms live or attenuated vaccines, human and animal cell cultures used in research and infectious agents from research and industrial laboratories, wastes from production of biologicals, toxins, dishes and devices used for transfer of cultures)

Category 6 – Soiled Waste (items contaminated with blood and body fluids including cotton, dressings, soiled plaster casts, lines, beddings and other materials

contaminated with blood.) Category 7 – Solid Waste

(wastes generated from disposable items other than the waste sharps such as tubings, catheters, intravenous sets – mostly plastic & latex disposables)

The waste belonging to the category 3, 6 and 7 are stored in Red liners

Feb 2010

100 kg / hr each – Modified Autoclaves

Feb 2010

Solar Water heater system supplementing the autoclave system and catering to the hot water needs at site

Treatment of waste sharps The waste metals sharps are treated in the Metal Sharps Manager

at the site. All the HCEs are provided with puncture proof metal

boxes which have keyhole arrangements that separate the needles from syringes. A protected opening for dropping the blades, canula needles and scalpels is also present in the box

The metal boxes are brought from the HCEs to the site; the metal sharps from the metal boxes are then transferred to the metal sharps manager, present at the site

The metal sharps manager has a powerful shredding mechanism which mutilates the needles into small pieces. The system is also retrofitted with hot air oven that sterilizes the mutilated needles at 164oC

Waste belonging to category 4 (needles, syringes, disposable scalpels, blades, sutures etc.) are treated in the equipment

Scenario before and after HEWMEP, Gulbarga & Implementation of CHAMP A ‘Knowledge, Attitude and Practice (KAP)’ survey in all

Healthcare Establishments (HCEs) in Gulbarga was carried out in 2002 (prior to implementation of CHAMP) and subsequently in 2007 - 2008 (after CHAMP became operational) for ascertaining the level of awareness and compliance to the biomedical waste management (BMWM) Rules and prescribed procedures

The survey showed that although the HCEs still lag behind in the implementation of various recommended BMWM procedures (specifically those which have cost implications), there has been tremendous improvement in awareness amongst the healthcare workers especially after implementation of CHAMP

Segregation of waste at source is improving but needs to be combined with improvement of collection and segregated treatment

Although the hospital staff in Govt. hospitals and Maternity homes are trained and aware about BMWM practices but they are not able to implement the practices properly due to lack of resources, facilities and motivation among the seniors in the HCEs

None of the hospitals were found disposing their liquid wastes properly

Emphasis on procedures for chemical disinfection for glass and immunization waste in rural areas, disposing of liquid waste in the urban and rural areas and training programmes for all Healthcare Workers (HCWs) is strongly recommended
