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 800-850 0 C and volatile gases emitted are again burnt in the secondary chamber at 1050 - 1100 0 C (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, CO 2 and O 2 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
Feb 2010 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
Feb 2010 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 164 o C Waste belonging to category 4 (needles, syringes, disposable scalpels, blades, sutures etc.) are treated in the equipment
Feb 2010 Hopper for sharp feeding Oven assembly for hot air sterilization Shredding Mechanism Shredded and sterilized sharps Metal Sharps Manager at CHAMP Metal Sharps Collection Box at HCES Key hole arrangement Opening for bigger sharps
Feb 2010 Discarded Medicines, Cytotoxic Drugs and Incineration Ash Category 5 comprises of wastes comprising of outdated, contaminated and discarded medicines Category 9 consists of incineration ash Category 10 consists of solid Chemical wastes The above mentioned waste is stored in Black Plastic Bags and kept for secured landfilling as per the BMWM Rules, 1998
Feb 2010 ETP at the CHAMP site The liquid effluent from the washing of the transport vehicles (nearly 4 cu.m. / day) will be treated in the ETP The treated water is to be used for plantation at the site.
Feb 2010 Vehicles for biomedical waste collection and transport Specially fabricated transport vehicles for biomedical waste. The vehicles are retrofitted with the ionizer – filter system to check escape of micro organisms to the surroundings
Feb 2010 Education and Training is an integral component of O&M of CHAMP which we call Healthcare Establishments Waste Management and Education Programme (HEWMEP) Training of HCE personnel is being done at different levels. This includes training for doctors, nurses, administrators, paramedical personnel, housekeeping staff, engineering, kitchen and laundry personnel, ayahs, wardboys, security staff, gardeners, rag pickers, sorters, reprocessors and people from different areas in the hospitals who are involved in Bio-Medical Waste Management (BMWM) Different types of educational material have been prepared, published and used for the training, with approval from MoEF, Govt of India, WHO-India & Govt. of Karnataka. The materials used are in Kannada, Hindi and English Education &Training on Biomedical Waste Management
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 Conclusion
