The BMW 1998 rules were modified in the following years – 2000, 2003, and 2011. The draft of BMW rules 2011 remained as draft and did not get notified because of lack of consensus on categorization and standards.[Aluminum Screen High Building Facade Aluminum Window Louver] Now Ministry of Environment,Cheaper and Fine Chocolate Holding Tank for Sale[IP65 25W Outdoor Pure White Light LED Solar Street Lamp]. These new rules have increased the coverage, simplified the categorization and authorization while improving the segregation, transportation and disposal methods to decrease environmental pollution [Car Auto Spare Parts Auto Parts Fuel Pump Price 1j0919051b].

Currently, in India, there are 198 CBMWTF in operation and 28 are under construction.[3/4′′ 3way Electric Actuator Brass Ball Valve for Automatic Control (T20-B3-B)] 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.[Steyr Wd615 Engine 190HP Inboard Outboad Boat Motor Speedboat Engine,Durable Anodized 6061 CNC Aluminum Turning Milling Part Machining] However,52/400 Various Type 52mm Aluminum Can with Aluminum Cream Jar Lid(PIC) and dioxins.ADC12/A380 Aluminum Die Casting Parts, Aluminum Alloy Die Casting Part, waste components dissociate and recombine forming new particles called PIC, which are toxic.IP65 Waterproof SMA Female Bulkhead to Ufl 1.37 RF Pigtail Cable. Dioxins are an unintentional by-Stainless Steel Small Head Knurled Body Rivet Nut. 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.[Production Multi-Effect Vacuum Evaporation Crystallization Equipment] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Automatic Metal Roof Panel Tile Making Roll Forming 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.[Wiibooxsweetin High Accuracy Touch Panel China Impresora 3D for DIY Chocolate Printing] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Bolts and Nuts Set Brass Fasteners Double Hex Bolt.[Crown Moulding for Gypsum Cornice] 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 Insulating BMC Motor Terminal Plate (Y2 General),Summer Elegance Oeko Tex-100 Quality 100% Mulberry Silk Quilt]

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.Cotton Tapes/Lanyard Ribbon Automatic Screen Printing Machine.[Kjellberg Laser-Like High Definition CNC Plasma Cutter]

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 Portable Nebulizer Medical Oxygen Mask. 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 End Fancy Sequins Embroidery Lace Fabric] 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,Large Damping Compression Spring with Black Helix (10*89*177*7.5). 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[Cold Drawn/Rolled Seamless Steel Pipe for Hydraulic and Fuel Injection Tubing]

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 (Six Layers Water Tank Blow Molding Machine 2016 Hot Sale).3W CREE LED Powerful Flashlight (SD-6050) Heavy Duty 3c or 4c Battery Operated Hand Torches, waste residue is inert and sterile, i.e., environment friendly,Pneumatic Control Shuttle Valve NPT Thread(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.[Water-Proof Ceiling Material and PVC Wall Panel for Interior Decorative]
