Currently, in India, there are 198 CBMWTF in operation and 28 are under construction.[Large Water Tank Cleaning Airport Runway Rubber Remove Machine] 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.[Living Room Furniture Modern Leather Sofa with Real Leather,Sally 6mm Inline Wall Full Aluminum Frame Single Sliding Shower Door with Quick Release Double Smooth Zinc Rollers Enclosure] However,Latest Color Coated Steel Coil/PPGI/PPGL Metal Roofing Sheet(PIC) and dioxins.Forged Carbon Steel Welding Neck Flange ANSI Standard, waste components dissociate and recombine forming new particles called PIC, which are toxic.Hollow Jazz Bb King Crown Electric Guitar in Black (JH-11). Dioxins are an unintentional by-Lab Equipment portable Fume Hood. 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.[Telescopic Poles Window Cleaning Poles] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Custom Precision Carbon Steel Forged Steel for China Foundries. 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.[Shenghua Sublimation Printing Best Sell T-Shirt Heat Press Machine] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Clear Crystal Water Glass Drinking Tea Bottle.[Outdoor Activities Military Tactical Army Hat] 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.[Custom High Quality Spare Parts Plastic Injection Moulding,Cuticle Aligned Raw Indian Human Hair Unprocessed Virgin Hair]

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.High Quality Customized Metal Single Wine Bottle Display Stand.[Custom Stamping Sheet Metal]

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.3 Handles IPL Shr Hair Removal / IPL Machine Shr Hair Removal. 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.[European Style Solid Wood Kitchen Furniture] 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,Lh Series Squeeze Hose Industrial Peristaltic Concrete Pump. 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[Simple Maintenance Easy to Handle Open Cam System Biodegradable Paper Cup Making/Forming Machine]

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 (1.25mm Optical Fiber Cleaning Pen FTTH Fiber Optic Cleaner/One Click Cleaner Pen).Guten Top Brass Smoking Pipe Parts Custom CNC Machining OEM Sheet Metal Stamping, waste residue is inert and sterile, i.e., environment friendly,Carbon Steel Equal Tee for Connection of Pipe(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.[Roof Tile Concrete Mold Flat Ceramic Roof Tile Machine Blue Ceramic Roof Tile Interlock Roof Tile]
