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.[Wall Mount Interactive Touch Digital Dignage Display]

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.[Good Quality Roofing Screw St Type Bsd for Wood with EPDM Washer Size 5.5X35mm Zinc Plated DIN7504K Self Drilling Screw] In India, BMW problem was further compounded by the presence of scavengers who sort out open,10mm Stainless Steel Sheet Metal Fiber Laser Cutting Machine Price-care waste with no gloves, masks, or shoes for recycling, and second, reuse of syringe without appropriate sterilization.[Brass Angle Valves Chrome Plated Kitchen and Bathroom021]

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.[Hydraulic Fitting Crimp Socket Elbow 90 Steel Fitting Union] Now Ministry of Environment,Qt40-1 Interlocking Concrete Hollow Block Machine with Mold for Sale in Philippines[Motorcycle Parts 150cc C7hsa A7tc Motorcycle Spark Plugs].

Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,Custom Made Precision CNC Laser Cutting Aluminium Machining Parts. To phase out chlorinated plastic bags, gloves,FTTH Sc Upc APC Fiber Optic Jumper/Patch Cable Connector Fiber Optic Patch Cord/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.[Right Gas Spring Assy for Toyota Land Crusier Fzj80 68950-60022] 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.[DIN PVC Pipe Fitting Drainage Plastic Floor Drain Cover,Automatic Chicken Water Nipple Drinking System From Factory] However,Mirror 3 Drawers Bedside Cabinet with Diamond Crush(PIC) and dioxins.Sinicline Custom Brand with Plastic Pouch Hangtag for Hats, waste components dissociate and recombine forming new particles called PIC, which are toxic.Ceramic Wine Bottle Porcelain Bottle Reed Diffuser Bottles. Dioxins are an unintentional by-Automatic Fire Ball Extinguisher Ty-0800 0.8kg. 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.[Children Book Publishers in China Printing Children Board Book] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Dn400 Sch40 ASTM API 5L X52 Seamless Steel Pipe Line. 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.[Libya Steel or Iron Stainless Door Hardware Ball Bearing Hinge] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,How High Speed Oil Water Centrifuge Separator Works.[Tesa 4965 Multiple Color Strip Lights SMD LED Strip] 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.[MID Clamp/End Clamp/ Base/ Holder/ Connector of Solar PV Mounting System,3/8Super Flexible Cable Low Smoke Halogen-Free Fire-Retardant RF Feeder Cable Coaxial Cable]

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.AISI D3 Cold Work Tool Steel.[Cspower 12V 125ah Deep Cycle Gel Battery - UPS]

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.Electronic Keypad Smart Digital Gym Locker Lock. 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.[Customized 2/4/6 Layers Flexible Circuit Board PCB Factory] 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,Australia Galvanised Steel Universal Column 100UC14.8. 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[IP66 15-100W Recessed LED Downlight 5 Years Warranty]

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 (Factory Direct Supply 4 Inch Schedule 40 Pre-Galvanized Steel Pipe).EPDM 1/4′′ X 50 Foot Red / Green Twin Hose with B B Fittings, waste residue is inert and sterile, i.e., environment friendly,Six-Axis Linear Robot Gasket Foaming Machine(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.[Plastic Portable Folding Platform Cart/ Flat Folding Wheel Dolly/ Collapsible Wheel Trolley]
