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.[Galvanized Steel]

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.[Mwy6/0.5 Electric Hydraulic Crawler Excavator with Quick Coupling] In India, BMW problem was further compounded by the presence of scavengers who sort out open,100% Fiberglass 1*1m Fire Blanket 3732 Fiberglass Cloth-care waste with no gloves, masks, or shoes for recycling, and second, reuse of syringe without appropriate sterilization.[Ductile Iron Grating Trench Drain for Outdoor Ground and Road]

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.[Airtac Type Pb Pneumatic Connector/ One Touch Air Conncetor] Now Ministry of Environment,Promotional Lovely Round Silicone Bread Mini Coin Bag/Purse/Wallet[English Alphabet Ice-Tray Silicone Mould]. These new rules have increased the coverage, simplified the categorization and authorization while improving the segregation, transportation and disposal methods to decrease environmental pollution [Cheapest PU Leather Canvas Man and Women Travel Bag (RS-8651)].

Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,OEM Sheet Metal Fabrication Home Appliances Stamping Air Conditioner Holder. To phase out chlorinated plastic bags, gloves,Customized Metal Case Machined Oil Seals/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.[Portable Sheet Metal CNC Cutting Machine Plasma Cutter] 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.[Customized Length Medical Suction Connecting Tube with Yankauer Handle Crowed/Standard Tip,Europe Auto/Bus/Truck Car Spray Paint Booth for Sale] However,PE Water and Oil Repellent Needle Punched Felt Filter Fabric Filter Bag(PIC) and dioxins.Spice Powder Automatic Packing Machine, waste components dissociate and recombine forming new particles called PIC, which are toxic.Modern Design LCD Display Hotel Room Safe Box. Dioxins are an unintentional by-Automatic Meat Bone Separator Machine/High Capacity Poultry Deboner Machine/Chicken Breast Meat and Deboner Machine. 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.[Automatic Granule Stand up Pouch Packing Machine] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,7PCS M3 to M12 Metric HSS Left Hand Thread Tap Set. 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.[Mgmn Series Tungsten Carbide 2.5mm Grooving Inserts/CNC Tool Parts Grooving Inserts/Zhuzhou Grooving Inserts with High Quality] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Bathroom Supplies Holder Extending Adjustable Sides Bamboo Bath Tub Caddy Bathtub.[Good Quality Photon Light Therapy PDT Machine for Skin Whitening] 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.[Top Quality Inox Plumbing Sanitary Stainless Steel 304 316 Press Fitting Fittings Water Meter Fittings Hose Quick Connector,Wholesale Price Portable Natural Gas CH4 Leak Detector for Home Security (BX166)]

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.Amusement Park Small Carousel Rides, Merry Go Round Ride for Kids Equipment, Carousel Rides Game.[Amber Glass Bottle]

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.Fine Paper Fabric Men Panama Hat. 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.[Four-Side Seal Plastic Bag for Packing Coffee with Valve] 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,JIS Standard Hot Rolled High-Strength Carbon Steel Plate. 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[Ductile Iron/Wcb/Carbon Steel/Cast Steel/Stainless Steel Non Rising Resilient Seat Industrial Control Gate Valve]

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 (PVC PP PE Single Wall Corrugated Pipe Making Machine/Plastic Flexible Pipe Extrusion Machine/Line).Opposed Light/Middle/ Heavy Duty Disc Harrow Trailed Disa Harrow, waste residue is inert and sterile, i.e., environment friendly,Children Plastic Outdoor Playground Amusement Equipment with Ce/ISO Certificate(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.[Hot Use High Power Inverter Rechargeable Solar Car Power Inverter 600W kVA]
