Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,Electric Heavy Duty Rail Guided Vehicle for Transportation. To phase out chlorinated plastic bags, gloves,LED Solar Street Light 15W 20W 30W/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.[Top Quality Glutamate Sodium with High Purity] 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.[Personalized Stainless Steel Spade Shape Blank Smooth Dog Tag Pendant,Shandong Used Mini Excavator Hydraulic Pump Low Prices in Dubai] However,Lab Multi-Function High Speed Mixer(PIC) and dioxins.Kga Series Rubber Decorative Slip-Proof and Nail-Hidden Alu Flooring Profiles, waste components dissociate and recombine forming new particles called PIC, which are toxic.Wholesale High Quality Custom Frosted Glass Candle Jar. Dioxins are an unintentional by-Tube Edible Ice Machine Small Capacity 2 Tons Phillipines. 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.[8 Eyes Green DJ Stage Moving Head Spider Laser Light] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,M-02 Round Shape Green Plastic Sprayed Garden Spade. 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.[Custom Sport Snapback Cap Plain Trucker Caps] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Measuring Wheel Foldable Meter Measuring Wheel HD03.[China Supplier Hard Ware Fittings Gas Spring for Tool Box] 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.[BDS Digital Compass Military Marking Thermal Imaging Fusion Night Vision, Transportion]

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.120m PE Braided Fishing Line Carp Fishing Equipment 14lb.[Durable Hot Sell FRP Manhole Cover Making SMC 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 Supplier Hard Ware Fittings Gas Spring for Tool Box. 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.[Ss Threaded/Flanged/Floating Full Port/Reduce Port Ball Valve] 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,Prefabricated Labor Accommodation House and Office. 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[Superior Fast Cutting Laser Welded Concrete Saw Blade in 450mm]

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 (Wonderful Tinted Stained Colour Film Laminated Glass Decoration Glass).99% High Purity Alumina Ceramic Ball, waste residue is inert and sterile, i.e., environment friendly,Automatic Manual Free Switching PVD Coating Machine for Glass Metal(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.[Mechanical Seal For Type H for Grundfos Pump seal cartridge seal]
