Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,Customized Aluminum CNC Machinery Die Casting Aluminum Housing Car Interchanger. To phase out chlorinated plastic bags, gloves,Original Mobile Phone LCD for Samsung Galaxy S8 G950 with Digitizer Touch Screen Assembly/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.[Interiro MDF/HDF White Primed Painted Molded Door From Factory] 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.[Cr800 Common Rail Injector Tester Simulator and Nozzle Tester Cr700,304 Stainless Steel Coil on a Flatbed Trailer] However,Automatic Extrusion Blow Molding Moulding Making Machine for Plastic PE PP PVC PETG ABS Bottle/Container/Drum/Barrel/Jerry Can/Toy/Water Tank/Auto Parts(PIC) and dioxins.54303-ED50b 333391 Front Left Japanese Cheap Shock Absorbers for Nissan, waste components dissociate and recombine forming new particles called PIC, which are toxic.Optical Laser Achromatic Triplet Lens. Dioxins are an unintentional by-High Quality 1680d PVC Coating Fabric Textile. 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.[New Design DC 12V 24V Mini Portable Camping Car Fridge for Ship] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Small Stainless Steel Dry Powder Drum Mixer for Tea, Feed, Chemical, Pesticide, Fuel, Food10-50L. 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.[Luzhong-700 70HP 2WD Two Wheel Drive Farm Tractor] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,High Tension Hot Dipped Galvanized Steel Wire Strand Guy Wire.[Hyaluronic Acid Moisturizing Facial Silk Mask Cosmetic] 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.[Classic Damascus Pattern PVC Wall Paper for Home,Diam38mm Tapered Cross Drilling Bit for Quarry]

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.Elastic Poplin Fabric with Fashion Ripstop Printed for Leggings.[Automatic EPS Food Box Thermoforming 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.China Best Quality Nutritional Reconstituted Artificial Rice 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.[Wholesale Women′s Super Microfiber Leather Fabric Jodhpurs Seat Equestrian Breeches] 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,Motorcycle Tube Making Machine/Inner Tube Making Machine. 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[Rotor Tip Set Suit Sandvik CV229 VSI Crusher Spares]

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 (Gearbox for Rolling Mill).Professional Electric Hair Clipper Cordless Beard Trimmer Men, waste residue is inert and sterile, i.e., environment friendly,Honeyson Guest Room White Small Security Digital Safe Box for Hotel(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.[ Men Roller Skate Shoes Sneaker]
