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.[Hot Sale Design Glass Top Metal TV Stand Table] Now Ministry of Environment,Bearing Unit/Stainless Steel Pillow Block Bearing/Rolamentos[Wholesale Clear Acrylic Wine Bottle Display Stands/Racks]. These new rules have increased the coverage, simplified the categorization and authorization while improving the segregation, transportation and disposal methods to decrease environmental pollution [100-220V Modern 400sqt Black 3D Fire Heating Electric Fireplace with Remote Control (EMP-001)].

Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,Four-Side Seal Plastic Bag for Packing Coffee with Valve. To phase out chlorinated plastic bags, gloves,700 Bar Hydraulic Stressing Jack Pump Hydraulic Power Pack Unit/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.[Aluminum Plate Fin Heat Exchanger/Oil Cooler Core] 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.[Brush Roller Potato Washer Machine,Fashion Cartoon Baby Hanger/ Fabric Satin Children Clothes Hanger (YLFBK004-N1)] However,Winter Warm Plush Knitted Kids Boots(PIC) and dioxins.Ce Certificated Hot Sell 55 Inch Axial Fan Industrial Poultry Greenhouse Exhaust Fan, waste components dissociate and recombine forming new particles called PIC, which are toxic.DC Mini Portable Car Fridge for Travelling with DC Compressor. Dioxins are an unintentional by-Plastic Injection Mould Design and Prototype From China. 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.[Top Selling Ceiling Tiles/Ceramic Tile Hydraulic Press Making Machine] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,2000L/H RO Water Purification System Stainless Steel. 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.[N52 Wholesales Nickel Coating Permament Neodymium Ball Magnet] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Factory Supply High Quality Hyaluronic Acid CAS 9004-61-9.[Natural Looking Synthetic Turf for Landscaping Grass] 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.[Hc Series China Hangzhou Advance Marine Gearbox 135A,Steel Rebar Coupler Machine Supplier in Malaysia]

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.Concrete Granite Stone Circular Saw Blade Diamond Segments Cutting Tool.[Carbide Cutting Wholesaler Quotes & PriceList]

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.Standard Ultrasonic Welding and Cutting Machine. 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.[2V500ah Solar Battery Bank with The Latest Technology] 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,Semi PU/PVC Upholstery Leather for Car Seat Automobile Marin Medical Furniture-Lab. 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[1200X2400mm Toilet Floor Tile Kuching Wholesale Island White Onyx Stone]

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 (HAIRUI 861DX 1200W Hot Air Mobile Phone Repairing Machine).12.1 Inch Capacitive Touch Screen with Ili2302 Controller for Industrial Touch Monitors, waste residue is inert and sterile, i.e., environment friendly,Silicone Rubber Bike/Motor/Scooter/Hand/Tool Handle Grips Sleeve(95%) and mass (80%–90%).
