In Canada, there is variation seen in the medical waste – management practices across different provinces. Not all provinces have regulations governing the handling and disposal of medical waste. However, Canada's hospital appears to moving away from on-site incinerators toward centralized provincial facilities for BMW sterilization.[Qt4-25 Foam Concrete Hollow Brick Block Machine with Cheap Price]

Biomedical Waste Situation in India

In July 1998, first BMW rules were notified by Government of India, by the erstwhile Ministry of Environment and forest.[Factory Directly Plastic Injection Paint Bucket/Barrel Molding] In India, BMW problem was further compounded by the presence of scavengers who sort out open,Aluminum Round Circle Disc 1050 1060 1100 3003 for Pot and Basin Aluminum Circle Prices-care waste with no gloves, masks, or shoes for recycling, and second, reuse of syringe without appropriate sterilization.[2019 Cartoon Kindergarten School Bags Fashion Backpacks with Customised Logo Design]

The BMW 1998 rules were modified in the following years – 2000, 2003, and 2011. The draft of BMW rules 2011 remained as draft and did not get notified because of lack of consensus on categorization and standards.[Color Painted Pan Head Self Drilling Screw] Now Ministry of Environment,Actuator Piston End Cap Fluid Valve Air Chamber Aluminum Die Casting[Advertising Inflatable Cartoon Dolphin Huge Helium Balloon]. These new rules have increased the coverage, simplified the categorization and authorization while improving the segregation, transportation and disposal methods to decrease environmental pollution [Wearable 130dB Personal Protection Alarm with Emergency Activation Key Ring Trigger with LED Light].

Simultaneously, the role of incinerator in increasing environmental air pollution has been checked by issuing new standards for incinerators and improving its operations.[Dongyue Sand AAC Block Making Machines]

Data from Government of India site indicates the total BMW generated in the country is 484 TPD (tonnes per day) from 1, 68,869 HCFs. Unfortunately, only 447 TPD is treated, and 37 TPD is left untreated. There are 198 CBMWTF in operation and 28 under construction. The number of HCFs using CBMWTFs are 1, 31,837, and approximately 21,870 HCFs have their own treatment facilities on-site.[ 1.4509 for exhaust systems]

As per the BMW Rules, 1998, and as amended, any HCF or CBWTF operator wanting to use other innovative and improved technologies other than stipulated under Schedule-I of the Rules, shall approach the Central Pollution Control Board (CPCB) to get the standards laid down to enable the prescribed authority to consider grant of authorization.Hospital Diagnostic Equipmemt Color Doppler Trolley Ultrasound, CPCB have granted conditional or provisional approval to new technologies (other than notified under BMW Rules) for treatment of BMW.

Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,Electric Cablle Kv PVC/PVC 3 Core (steel tape armored) VV22, Vlv22 Cable Cord and Wire. To phase out chlorinated plastic bags, gloves,PVC Blank Flange of Pipe Fittings for Water Supply/containers the cost will be high and time span for doing this i.e. two years is too short.

Currently, in India, there are 198 CBMWTF in operation and 28 are under construction.[High Quality Pharmaceutical Peptides Alarelin Acetate for Bodybuilding] There is a great need for rapid development of many more CBMWTF to fulfill the need of treatment and disposal of all BMW generated in India. Incinerator emit toxic air pollutants, and incinerator ash is potentially hazardous.

Incinerator and its Hazards

The first solution for the disposal of BMW was to burn the waste. India in the late 1990s after the first BMW rule was implemented, saw a boom in the number of incinerator being installed. It is based on high temperature that kills pathogen and in the process destroys the material in which the microbes reside.[Shunfu Sales Napkin Printing Embossed Paper Folding Machinery,Yg Duct Tape with Smooth Surface] However,Mining Industry Use Conveyor Belt with Ce Certificate(PIC) and dioxins.2019 Cartoon Kindergarten School Bags Fashion Backpacks with Customised Logo Design, waste components dissociate and recombine forming new particles called PIC, which are toxic.American Outdoor Chair Cafe Chair Restaurant Best Quality Cafedeira Only Sell to USA (SP-OC001). Dioxins are an unintentional by-Double Sided Aluminum Foil Bubble Thermal Insulation Material/ Double Sided Reflective Foil Insulation for Roof and Wall. These are a group of 75 chemicals which coexist along with another group of toxins called furans. These toxins have a tendency to accumulate in fatty tissues and travel up the food chain. Burning of medical devices made up of polyvinyl chloride (PVC) is the largest dioxin producers in the environment.[EMC EMI RF Shielding Room MRI Door for Hospital] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Pet Polyester Fabric Mesh Belt for Non-Woven Forming. In India, till date, no study has been done by Government of India to estimate the level of dioxin in Indian population. In 2000, Subramanianet al. have found high level of dioxin in the human breast milk collected from New Delhi, Mumbai, and Kolkata.[Super Duplex 904L 2205 2507 Stainless Steel Plates Metal Sheet] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Wooden Texture Spc Click Lock Vinyl Rigid Core Flooring.[Welding Electrode Price of Welding Rod E7018/E7016/E7015 Welding Electrodes Sea Bridge Brand] Moreover, the incinerator ash is also hazardous and needs to be checked for the level of toxin before being sent to secured landfill. Therefore, keeping these points in consideration, most of the countries are shifting to alternative environmental friendly methods of BMW disposal. The Philippines has banned incinerator and Denmark has banned construction of incinerator.[Custom Made Auto Element Molded Rubber Parts,Best Value Low Power Heating Mantle 2L]

Alternative Technology for Biomedical Waste Disposal

The various new technologies for BMW disposal are categorized into four groups – thermal, chemical processes, irradiative processes, and biological processes.Ms Square Hollow Section/Rectangular Hollow Section/ Hollow Section.[Anti-Skid Diamond Pattern Rubber Garage Floor Mat Rubber Products for Floor Promotion]

Thermal processes are grouped into three – low, medium, and high.

1. Low heat technologies operate between 93°C and 177°C and include microwaves and autoclaves. In autoclave, steam is used as a method for sterilization. Autoclaves are classified based on the method for removal of air pickets – Gravity/downward displacement and prevacuum/high vacuum. Since air evacuation is more effective in autoclaves with a prevacuum or multiple vacuum cycles, these are better.Shenglin Rooftop Cooling System Roof Top Mounted Air Conditioner. The evacuated air is disinfected before disposal into the environment by passing through a high-efficiency particulate absolute (HEPA) filter as it may contain pathogens. All infectious waste including cultures, human waste, laboratory waste, soft waste (gauze, bandages, and gowns) and sharps, and medical instruments are sterilized in autoclave. Hazardous waste and chemicals cannot be autoclaved as they release toxic emissions. Furthermore, heat resistant containers, beddings, and other bulky waste cannot be disinfected in autoclave.[Self Cleaning Lazy Woman House Cleaning Flat Mop] Microwave uses moist heat and steam generated by microwave energy to disinfect. All infectious waste including human waste, laboratory waste, soft waste (gauze, bandages, and gowns), and sharps are sterilized in microwave. Volatile, semi-volatile organic compounds, mercury,High Quality Air Couch Inflat Custom Cinese Factory. The advantage of using microwave for BMW disposal is minimal emissions. Its disadvantage include requirement of high capital for setup, problem of odor near the machine, and there is a chance of leak of microwave energy

2. Medium heat technologies operate between 177°C and 540°C and include reverse polymerization and thermal depolymerization. This involves the application of high-energy microwaves in nitrogen atmosphere to BMW to breakdown the organic matter. As the waste absorbs the microwave energy, its internal energy increase and chemical decomposition take place at molecular level. Nitrogen provides an oxygen-free environment so that combustion does not take place. Then, shredders are used to mutilate the waste[Stylish Summer Safety Shoes Protective Toe and Midsole Slip Resistant Work Shoes Sc-8803]

3. High heat technologies operate between 540°C and 8300°C and include pyrolysis – oxidation, plasma pyrolysis, induction-based pyrolysis, and lase-based pyrolysis. In pyrolysis oxidation, inside the pyrolysis chamber, the organic solid and liquid waste vaporize at high temperature (approximately 594°C) leaving behind inert ash and glass and metal fragments. This is followed by second step, wherein combustion of the vapors takes place at a temperature of 982°C –1093°C in a chamber and clean exhaust steam is later released.

Plasma pyrolysis uses plasma torches to generate plasma energy. In plasma state, the ionized gas can conduct electric current, but due to its high resistance, the electric energy is converted to heat energy. The residue generated include carbon black, vitrified glass aggregates, and metallic residues. A wide variety of waste can be destroyed in plasma-based technology – infectious waste, sharps, plastics, dialysis waste, hazardous waste, chemotherapeutic waste, chemotherapy waste, and low-level radioactive waste (Rubber O Rings Rubber Products Rubber Parts Rubber Oring Seals and Gaskets).Canoe Manufacturers 2 Persons Carbon Fiber Ocean Transparent PC Kayak, waste residue is inert and sterile, i.e., environment friendly,Hpk-Y Series Chemical Industrial Circular Pumps(95%) and mass (80%–90%). Its disadvantage includes high capital cost, high operation cost, high electrical usage, limited lifespan of plasma torch and may generate dioxins in poorly designed setup.[Ss 904L]
