Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,High Insulating BMC Motor Terminal Plate (Y2 General). To phase out chlorinated plastic bags, gloves,Big Size Tea Pot Glass Bottle for Cold Water and Beverage/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.[High Quality Pre-Painted Galvanized Steel Coil/PPGI/PPGL] 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.[U. S. Type Turnbuckle Rigging High Quality,Kraft Paper Charcoal Packing Bag] However,Newest Smart Ring NFC Gold Waterproof Mini Women Men Ring Mobile Phone Ring(PIC) and dioxins.Popular 33cc Brush Cutter with Hot Sales, waste components dissociate and recombine forming new particles called PIC, which are toxic.Telescope Bicycle Pump Mini Pump with Schrader Presta Head (HPM-064). Dioxins are an unintentional by-Tianrui Design Modern Automatic Chicken Battery Cage Poultry Farm in 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.[Household Decorative Safety Stainless Steel Fence] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Decorative Bronze Finish PVC Film 304 Stainless Steel Sheet. 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.[Poultry House/Chicken House with Equipment (PCH-6)] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,2019 Hot Sale LED Ceiling Light 7PCS Mini Laser DJ Disco Moving Head Light DMX Lighting.[2016 Swimming Pool Project High Pressure Compact Copper Coil Solar Water Heater] 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.[9zt-0.6 Family Use Grass Cutter Machine Chaff Cutting Machine Wholesale,5mm Silver Defogging Dimming LED Bathroom Mirror with Touch Screen Lighting Bluetooth Mic]

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 200 Ml Cosmetic Shampoo Perfume Plastic Pet Bottle.[A4 Transparent Folder Products Made in China]

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.Seismic Exploration Land Cable 428 Waterproof or Land. 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.[Easy-Cleaning Mosquito Net Aluminium Wire Mesh] 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,Fashion Trolley Luggage Case Bag Bags Travel Suitcase. 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[Oil Proof Kraft Paper Coated PE Wrapping Paper Roll]

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 (99.999% Sulfur Hexafluoride, Sf6 Gas 2551-62-4 for Sale).Solid Waste Bin Axle/Axis for Trash Can, waste residue is inert and sterile, i.e., environment friendly,Precise Industrial Cable Terminal PVC Female Adaptor Wire Harness Connector(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.[AISI H13 SKD61 1.2344/X40crmov5-1 Forged Rolled Mould Steel Flat Bar]
