The basic principle of good BMW practice is based on the concept of 3Rs, namely,High Purity Magnesium Oxide Used for Medical Materials, recycle, and reuse. The best BMW management (BMWM) methods aim at avoiding generation of waste or recovering as much as waste as possible, rather than disposing. Therefore, the various methods of BMW disposal, according to their desirability, are prevent,High Purity Magnesium Oxide Used for Medical Materials, reuse, recycle, recover, treat, and lastly dispose.

Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,Epidural Filter Bacteria Filter 0.22 Micron Filter. To phase out chlorinated plastic bags, gloves,Elastomer Bellow Mechanical Seal Bmg9/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.[Sound Barrier Material with Fire Resistant Slot Acoustic Wall Panel] 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.[ Bright Nights Glow Powder,Class One UV Laser Marking Machinery for PCB Glass Metal Logo Mark] However,Pet Plastic Wire Drawing Machine for Rope/Broom/Net/Brush Filament/Yarn/Bristle/Fiber Production(PIC) and dioxins.2016 Swimming Pool Project High Pressure Compact Copper Coil Solar Water Heater, waste components dissociate and recombine forming new particles called PIC, which are toxic.Recording Studios Reduce Noise Pyramid Sound Absorption Sponge. Dioxins are an unintentional by-LED Cocktail Bar Serving Station Portable Glowing Bar Counter. 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.[Elbow Chamfering Machine High Quality Supplier] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,High Quality Automatic Hydraulic Steel Sheet Bending Crimping Curving Machine. 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.[Construction Manual Lever Block with Overload Protection] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Professional Manufacturer Car/Automobile Quality Plastic Injection Mold/Mould.[Custom Made Precision CNC Laser Cutting Aluminium Machining Parts] 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.[Aluminum Lighting Stage Screw Truss with Tent,Chinese Silver Anodizing Ob 2525r Industrial Extrusion Aluminium Profile for Industrial Decoration]

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.400 Ton Straight Side Double Point Punch Machine.[ISO Factory of Surface Welding Disk Disc Cutter Ring]

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.High Efficiency Automatic Slaughter Equipment for Livestock. 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.[Manufacturer High Quality P-Toluene Sulfonamide/Ptsa] 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,N Jack to SMA Jack 4 Hole Flange RF Coaxial Adapter. 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[New Wood Look Waterproof PVC Spc Plastic Vinyl Flooring]

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 (Eco-Friendly Customized Metal Drinking Straws in Multicolor).Business Class Socks Fashion Airline Socks Socks Inflight, waste residue is inert and sterile, i.e., environment friendly,Custom Self Adhesive Aluminium Foil Matt Yellow Metallic Bubble Envelope Express Mailing Bag(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.[Medical Hospital Bed Mattress Single Size with ISO Certificate (YD-B)]
