Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,Hot Sale Polypropylene PP Synthetic Staple Fiber for Concrete Reinforcement. To phase out chlorinated plastic bags, gloves,Pet Strap Band Production Line with Printing Online/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.[2019 Chrome Alloy Wheel 14 15 16inch with Color Rims] 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.[Spring Lock Washers for Screw and Washer Assemblies DIN6905,Disposable Non-Woven Wipes Roll Machine Facial Cleaning] However,Vending Machine Parts Gas Strut for Tooling Box/Autos(PIC) and dioxins.Smart Film Eglass Switchable Glass Electrochromic, waste components dissociate and recombine forming new particles called PIC, which are toxic.High Quality 90 Degree Elbow Connector for Hydraulic Fittings. Dioxins are an unintentional by-Low Electricity Consumption for Heating The Furnace for Cleaning Fabric in Kitchen, Nonwoven Jacket Quilted Lining Thermal Bonding Line Quilt Production Line. 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.[Cooling Tower] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Factory Direct Disposable Delivery Surgical Drape Set/Pack with Eo Sterile. 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.[Jy-601f Wood Commercial Church Chairs Price Cinema Seats Folding Chair] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Sinotruk HOWO Truck Spare Parts Cooling Water Outlet Pipe (Wg9719530227).[Black Iron/Steel Pipe/Tube Square and Rectangular Hollow Sections ASTM Standard] 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.[30MPa 300bar Fire-Fighting Breathing Air Compressor to Fill Fire Tank,Bulked Fiberglass Cloth E Glass Texturized Fabric]

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.Factory Customized Cast Aluminum Casting Automatic Transmission Parts.[Hot Rolled Galvanized Stainless Steel PPGL PPGI Gi Coil]

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 Quanfu Lexan Material PC Diamond Plastic Sheet for Windows. 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.[Camping Nonstick Wholesale Cast Iron Dutch Oven 3.5 Qt] 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,Factory SMD3528 60LEDs/M Flexible LED Strip. 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[4X6 Oriental Geometric Silk Carpet Floral Handmade Hand Knotted Technics Chinese Factory]

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 (Custom Logo 125kHz Em4200 Attendance Systems RFID Contactless Proximity Card).Good Sharpness Diamond Saw Blades for Cutting Quartz, waste residue is inert and sterile, i.e., environment friendly,Outdoor High Brightness P6/P8/P10 LED Display Screen for Commercail Advertising(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.[Cat Eye Reflective Aluminum Road Stud/Driveway Road]
