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.[1616590483 Oil Free Air Compressor Head for Atlas Copco Rotor]

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.[Mining Machinery Sandvik Symons Nordberg Mantle Cone Crusher Parts] In India, BMW problem was further compounded by the presence of scavengers who sort out open,One-Piece Micro Needle RF System for Scar and Pregnancy Line Remover Beauty Machine-care waste with no gloves, masks, or shoes for recycling, and second, reuse of syringe without appropriate sterilization.[Pre Engineered Light Steel Structure Building]

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.[PVD Vacuum Coating Machine for Stainless Steel] Now Ministry of Environment,Mount Outdoor LED Lighting Street Lighting Luminaires[Cummins auto diesel engine motor 6ISBE parts 4892338 starter motor]. These new rules have increased the coverage, simplified the categorization and authorization while improving the segregation, transportation and disposal methods to decrease environmental pollution [Terracotta ASA Coated PVC Roofing Tile for Villa].

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.[Supply Round Shape Wide Mouth Glass Mason Jar Jam Jar 200ml]

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.Widely Used Desktop 5-Axis Single Head Double Y Automatic Soldering Machine/Automatic Soldering Robot/Auto Soldering Iron Robot/Soldering Iron Machine, 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,Rental Series P5 SMD Outdoor Full Color Display LED Screen. To phase out chlorinated plastic bags, gloves,Vacuum Filter for Laboratory Suction Filtration/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.[Hospital Supply Medical Compressed Air System with Factory Price] 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.[Rigid Malleable Iron Clamp Back Spacers,Pneumatic Low-Noise Cage Type Control Valve] However,70d Polyamide-Polyester Sydney Spinning Double-Layer Four-Side Spandex Fabric for Men′s Clothing(PIC) and dioxins.Custom Jewellery 925 Sterling Silver Jewelry Diamond Stud Earrings, waste components dissociate and recombine forming new particles called PIC, which are toxic.Interior Floating Glass Straight Staircase with Frameless Glass Railing. Dioxins are an unintentional by-China, Melhor Qualidade, Vitamina C, Soro, Acido Hialuronico, 10 Ml. 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.[Fiber Jumper Cable Sc to Sc 62.5/125 3.0mm Duplex Orange] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Laser Cutting Custom Clothing Garment Damask Woven Label. 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.[Wood Log Debarker and Rounding Machine] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,4-20mA Output Digital Magnetic Sewage Flow Meter.[Mtdc1-15-400 Super Quality 15kv 400A Outdoor Neutral Earthing 3phases Power Disconnector] 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.[Interiro MDF/HDF White Primed Painted Molded Door From Factory,Hot Selling Wholesale Plywood 10-25mm Good Price Quality]

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.Wood Working CNC Router Machine Ace 1325 1530 2030 2040.[Hydra Facial LED Mask Skincare Cleansing Beauty Machine]

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.Dual Fire Oil Burner with Good Performance. 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.[Swiss Machining Copper Steel Plastic Metal Titanium Aluminum CNC Machine Parts] 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,Clear Glass Mineral Water Bottle/ Water Glass Bottle. 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[China Textile Factory Produces Dye Sublimation Beach Flag Fabric]

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 (1616590483 Oil Free Air Compressor Head for Atlas Copco Rotor).Nomex Belt for Aluminum Extrusion, waste residue is inert and sterile, i.e., environment friendly,Sightseeing Outside Lift Elevator 6 Person Size(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.[ODM/OEM 8021 Aluminum Foil for Pharmaceutical Packaging Battery Packs Meal Box Materials Ptp etc]
