It follows the cradle to grave approach which is characterization, quantification, segregation, storage, transport, and treatment of BMW.

The basic principle of good BMW practice is based on the concept of 3Rs, namely,6.35mm Mono Plug to 2X RCA Jacks, 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,6.35mm Mono Plug to 2X RCA Jacks, reuse, recycle, recover, treat, and lastly dispose. Hence,PVC Foam Board Extrusion Machine Production Line“end of pipe approach.”[Sany 22ton Hydraulic Excavator Bucket Sy215c]

To phase out chlorinated plastic bags, gloves,Customized Sizes Long Floor Drainer SUS304 Bathroom Fittings (BF-K72)/containers the cost will be high and time span for doing this i.e. two years is too short.

Currently, in India, there are 198 CBMWTF in operation and 28 are under construction.[Little Ant Golden Marble/ Ceramic/Tile Cutting Saw Blade] 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.[ Wholesale Unprocessed Virgin Brazilian Hair Bundles,Manufacturer Print Design Knittedcotton Kids Vest] However,Cast Floating Ball Valve China Manufacturer (GAQ41F)(PIC) and dioxins.Direct From China Factory Ultrasonic Plastic Welding Machine, waste components dissociate and recombine forming new particles called PIC, which are toxic.18mm Frostil White Slotted /Grooved MDF for Shelf. Dioxins are an unintentional by-Sany Hydraulic Excavator Sy16-Sy465 Mechanical Spare Parts Cylinder. 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.[Dsola Factory Wholesale Professional Standard 300W Mono Solar Panel] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Home Use Inflatable Cartoon Moonwalk for Party Rental. 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.[High Pressure Spraying Washing Machine for Jam Production Line] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,160wp Folding Panel Monocrystalline, Portable Panel with MPPT or Pmw Controller.[Custom Medical Instruments Plastic Parts Injection Molding Company] 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.[Hot Sell Simple Wooden Watch Quartz Movement OEM in China,High Quality Waterproof Outdoor Lifesaving Flashlight Torch (SYSG-517)]

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.CNC Deep Hole Gun Drilling Machine.[EV Charging Station 240V with Type 2 Outlet]

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.Best Seller EVA Sheet in Hardness 30-55 Degree Shore C. 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.[Carbon Steel Zinc Plated L Shape Sleeve Anchor Bolt with Hooks] 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,Ce Desktop Constant -Temperature Incubator Wp25ab 18L. 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[Empty Atomizer Refillable Perfume Travel Spray Bottle Glass & Aluminum Mini]

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 (Aluminum Profile CNC Precision Cutting Saw Double Head Type).Hot Sale Network 1.3 Megapixel Wireless IP Mini Camera, waste residue is inert and sterile, i.e., environment friendly,Custom Made California King Size Furniture of Headboard and Bed Frame (ZBS-871)(95%) and mass (80%–90%).
