Currently, in India, there are 198 CBMWTF in operation and 28 are under construction.[Christmas Cheap Dessert Round Paper Baking Cups] 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.[China 3150kVA 33kv Oil Immersed Transformer - China Power Transformer,UHP 450 Graphite Electrode Made in China] However,Hydraulic Nc Bending Machine(PIC) and dioxins.Nordberg C110 C125 C140 Jaw Crusher Spare Parts Fixed / Swing Jaw Plate, waste components dissociate and recombine forming new particles called PIC, which are toxic.Zinc Galvanized Allen Drive Flat Head Self-Tapping Screws. Dioxins are an unintentional by-Automatic Press Roller Net Type Veneer Drying Machine for Plywood Making. 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.[China Factory and Manufacturers Industrial Grade Cellulose Ethers HPMC] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,EVA Foam Press Molding Machine Used for Rubber Shoes. 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.[Wholesale New Fashion Casual Shoes Blue Canvas Shoes for Men] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,1.5inch Mini Hidden Car Dash Camera for America Europe Marketing.[Anti-Static Frosted Polycarbonate Multi Wall Hollow Sheet for Public] 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.[Factory Supply FC Male-LC Female Single Mode Simplex Fiber Optic Adapter,High Temperature Ceramic Fiber Special Shape Product]

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.Hot Professional Xs200 CNC Machining Center Atc Machine China.[Soil Moisture Water Sensor]

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.Disposable Breathing Exchange Filter Bacterial & Virus Filter Breathing Filter. 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.[Small Portable Pressure Tank Direct Drive Air Compressor 2HP/2.5HP (50L tank)] 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,350ml/500ml Insulated Classic Stainless Steel Double Wall Thermos Milk Bottle Flask. 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[Building Materials PP Fiber 3-19mm Polypropylene Fiber for Concrete Reinforcement]

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 (JIS Misumi Standard Round Latch Locks for Injection Molds Parts Return Units for Moulds Components).Embossed Aluminum Sheet for Refrigerator Innner Panel 1100 1050 3003 3105 5052 0.4mm 0.6mm 0.8mm, waste residue is inert and sterile, i.e., environment friendly,Polypropylene Micro Synthetic Fiber Fibratex Fibrillated / Mesh / Reticular Shape(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.[Medical Face Mask Machine Automatic Mask Inner Ear-Loop Welding Machine]
