Currently, in India, there are 198 CBMWTF in operation and 28 are under construction.[Pneumatic Control Shuttle Valve NPT Thread] 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.[Heavy Duty Lid Stay Soft Close Lip Stay Support Hydraulic Lift Gas Spring,Teflon Paper for Heat Press] However,Heavy Duty Lid Stay Soft Close Lip Stay Support Hydraulic Lift Gas Spring(PIC) and dioxins.ODM/OEM 8021 Aluminum Foil for Pharmaceutical Packaging Battery Packs Meal Box Materials Ptp etc, waste components dissociate and recombine forming new particles called PIC, which are toxic.Tianrui A Type automatic egg chicken layer cage feeding system. Dioxins are an unintentional by-Haivol High Voltage 12/20kv Cold Shrinkable 1 Cores Indoor Terminal Kit (Applicableof cable crosssection 95). 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.[Silicone Molding Service] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Dn-6 Fully Automatic and Computer Controlled Single-Needle Quilting 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.[Aluminum CNC Turning Metal Milling Machining Parts] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,HDMI VGA DVI AV Input 55inch electronic whiteboard white board.[Yto 3 Ton Diesel Forklift Cpcd30A1] 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.[High Quality CAS 10040-45-6 Sodium Picosulfate with Best Price,Wine Cocktail Decoration Biodegradable Paper Straw]

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.Vacuum Brazed Diamond Saw Blade for Metal Diamond Tool.[Winter Warm Plush Knitted Kids Boots]

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.CNC Machinery Industrial Parts and Tools Fitness Equipment Accessories Medical Tube Plastic Extrusion Machinery Industrial Part. 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.[High Quality PU/TPU Tape for Garment] 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,Hot Fashion Colored Crystal Glass Ornaments Bulk Glass Tealight Candle Holder Centerpiece. 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[Factory Hollow Section Hot Dipped Galvanized Square /Rectangular Steel Tube or Pipe for Africa /Middle East / Southeast Asia Markets]

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 (Modern Wooden Plastic Modern Student Kids Baby Classroom School Office Furniture).1000VDC 30A T Branch Mc4 Solar DC Connector for PV Photovoltaic System (4 TO 1), waste residue is inert and sterile, i.e., environment friendly,Hypoallergenic 100% Polyester Microfiber Duvet(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.[950 Mechanical Seal Water Pump Mechanical Seal]
