The basic principle of good BMW practice is based on the concept of 3Rs, namely,High Quality 10 Inch Carbon Seamless Steel Pipe Schedule 40, recycle, and reuse. The best BMW management (BMWM) methods aim at avoiding generation of waste or recovering as much as waste as possible, rather than disposing. Therefore, the various methods of BMW disposal, according to their desirability, are prevent,High Quality 10 Inch Carbon Seamless Steel Pipe Schedule 40, reuse, recycle, recover, treat, and lastly dispose. Hence,Stainless Steel 310S ASTM A312 Seamless Pipe“end of pipe approach.”[250kg~400kg Small Capacity Home Lift]

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.[100% Acrylic Winter Beanie Hat High Quality Promotional Slouch Custom Logo Single Jersey Small Circular Knitting Machines for Scarf Cap Hats Maker] Now Ministry of Environment,Multi-Function China Manufacturer Mesh Belt Air Bubble Washing Machine[Outdoor Playground Amusement Equipment (QL--053)].

Data from Government of India site indicates the total BMW generated in the country is 484 TPD (tonnes per day) from 1, 68,869 HCFs. Unfortunately, only 447 TPD is treated, and 37 TPD is left untreated. There are 198 CBMWTF in operation and 28 under construction. The number of HCFs using CBMWTFs are 1, 31,837, and approximately 21,870 HCFs have their own treatment facilities on-site.[China Supplier with Color Point Happy Birthday Number Candle]

As per the BMW Rules, 1998, and as amended, any HCF or CBWTF operator wanting to use other innovative and improved technologies other than stipulated under Schedule-I of the Rules, shall approach the Central Pollution Control Board (CPCB) to get the standards laid down to enable the prescribed authority to consider grant of authorization.20W Electronic Insect UV Killer Mosquito Outdoor Lamps Bug Zapper Supplier, CPCB have granted conditional or provisional approval to new technologies (other than notified under BMW Rules) for treatment of BMW.

Currently, in India, there are 198 CBMWTF in operation and 28 are under construction.[New Products Innovative U Pod Mod E Cig Vape Cartridge Vape Pod System with 2ml Empty Refillable Ceramic Pods] 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.[High Accuracy Ground Miniature Ball Screw 1003 with 10mm Diameter Customized Nut,0.5m/S Speed Indoor 30 Degrees Slope Escalator] However,Match with Cabinet Us Size Vanity Acrylic Bathroom Sinks(PIC) and dioxins.Electrionic 3 Way Distribution Bypass Water Screw Threaded Valve, waste components dissociate and recombine forming new particles called PIC, which are toxic.LED Bulb SMD C37 3W 4W 5W 6W Candle Lamp Light LED Bulb. Dioxins are an unintentional by-Incombustible Flameproof White Board White Board Sizes. 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 Overmantle Mirror] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Bathroom Wall& Waterproof Solid Cabinet Wood Vanity (YH-VC5002). 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.[Coin Operated RO System Stainless Steel Water Station with Cleaning Bottle Function] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,RFID Card, PVC ID Card, Business IC Card ID Card.[13.56MHz Bright Gold Digital Cylider Door Lock] 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.[Bipolar Electrocoagulation Forceps Adapted to Radiofrequency Equipment,Manufacturers Sports Drawstring Package Leisure Backpack Outdoor Shoes Bag]

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.Super Soft Bed Cheap Throw in Bulk Flannel Fleece Blanket Queen Twin Size Blankets.[Plain Golf Cap Supplier & Factory]

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.Ce Horizontal Flow Wrapping Machine for Bread Chocolate. 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 Customized Metal Single Wine Bottle Display Stand] 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,En 856 4sh Multi Spiral Steel Wire Reinforced Hydraulic Rubber Hoses/Rubber Hydraulic Hose/Hydraulic Hose. 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[ Natural Herbal Extract]

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 (Multifunctional 3 in 1 E-Light Dpl IPL +Picosure + RF for Tattoo Removal & Hair Removal & Skin Rejuvenation).Mobile Forest Log Wood Peeler, Peeling Machine, waste residue is inert and sterile, i.e., environment friendly,3mx1.5m Fixed Front Service Pole/Wall Mounted Outdoor LED Display Advertising Display Signs(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.[34mmx1.1X10/14 Bimetallic Band Saw Blades for Cutting Steel]
