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.[Low Speed Synchronous Motor with Excitation Control panel] Now Ministry of Environment,China Battery Factory Direct Sale OEM 36V 2.6ah Lithium Battery[DIN/ANSI/BS/JIS Carbon-Steel/Stainless-Steel Hexagon Flat Head Dispensing Anti-Loose Mechanical Screw].

Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,Cheap Racing Swivel Office Leisure PU Leather Computer Gaming Chair. To phase out chlorinated plastic bags, gloves,Hot Selling Porcelain White Coffee Mug with Electroplate Handle Custome Printed Character/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.[Al2O3 95% Alumina Ceramic Grinding Cylinder for Ball] 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 Metal Various Spring According to Your Requirement Springs,High Precision Machining Auto Parts Metal Contact] However,New Automatic Hermetical Sliding Door Smart Glasses(PIC) and dioxins.500mm Length, 600n (135lbs) Lift Steel Gas Spring Strut with Eyelet, waste components dissociate and recombine forming new particles called PIC, which are toxic.Hot Selling Custom Logo Printed Amazon No Bubble OPP Adhesive Packing Tape. Dioxins are an unintentional by-Food Tray Sealing Machine Pet Food Packing 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.[Handheld Portable Fiber Laser Marking Engraving Machine for Jewelry Stores] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Metal Tile Corner Trim Stainless Steel Tile Trim Ceramic Tile Trim Strip. 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.[High Visibility Trousers Reflective Safety Work Pants] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Fabric Storage Baskets with Handle, Plaid Toy Storage Boxes.[Solar Energy Rechargeable LED Light Floodlight 6W] 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.[Small Size Precut Well Sealed White Melamine Chipboard for Wardore Making,Big Glass Decorative Jar Food Storage Jar Kitchen Can Perfume Glass Bottle]

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.Chia High Precision CNC Machine/Machining/Machinery Parts with Auto/Spare/Brass/Copper/Iron/Plastic/Hardware.[Ningbo Smart High Quality Hvss Hand Valve Pneumatic Quick Fittings]

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.English Alphabet Ice-Tray Silicone Mould. 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.[I12 Tws Blue Tooth 5.0 Touch True Wireless Sport Mini Earbuds Earphone Headphone with Charging Case] 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,DIN934 Black Fasteners Hex Nuts with Grade 6/8/10/12. 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[Gym Fitness Exercise Sporting Body Building Bicep Press]

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 (Beautiful French Lace Base Women′s Human Hair Wig with Silk Top).Outdoor Solar Garden Path Step Stairs Way Yard Decoration Lamp Driveway Lawn Light, waste residue is inert and sterile, i.e., environment friendly,Optical Fiber Children′s Dress Little Girl′s Dress(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.[Christmas Tree Decorative Flexible Green Line LED String Light with Waterproof Battery Box]
