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,Chicken Paw/Wing/Leg/Meat Weight Sorter with Low Price, 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,Chicken Paw/Wing/Leg/Meat Weight Sorter with Low Price, reuse, recycle, recover, treat, and lastly dispose.

Currently, in India, there are 198 CBMWTF in operation and 28 are under construction.[Wide Mouth Glass Jar with Lid] 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.[Zinc Oxide 99.7%,Fire Fighter Heat Resistant Working Gloves] However,Custom Printable PVC 125kHz EM4200/TK4100  RFID Student ID Card(PIC) and dioxins.HD Night Vision IR Laser Camera with PTZ for 1200m Surveillance, waste components dissociate and recombine forming new particles called PIC, which are toxic.Sch 40 API 5L-X42 PE Coated 12m LG Seamless Pipe. Dioxins are an unintentional by-Lsa061 Limit Switch Spring Boom Pin IP65. 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.[Internal Conical Steel Pipe] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,The Oil Filter Housing Fram Oil Filter. 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.[Green Professional Making Extrusion Blowing PE Bottle Mould Factory] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,20 24 28 32 4PCS Luggage Sets ABS Hard Shell Case Trolley Suitcase.[Refined Pure Metal High Purity 99.99% Lead Ingot] 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.[Mayflay Steel Plate and Sheets Small Shot Blasting Machine Price,Excavator Parts 8e0468 Bucket Teeth Pins]

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.30W CREE COB LED Track Light for Clothes Shop Lighting.[New Designs Sequins Lace Fabric for Evening Dress]

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.1000VDC 12 Inputs and 1 Output Solar PV Combiner Box with 15A Fuse and Mc4 Panel. 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.[Women Holographic Glitter Fanny Pack Ladies Beauty PU Waist Bag] 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,HS-2002 Hotel Lobby Scent Marketing Fragrance Machine. 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[27-0017 Tactical Military Combat Airsoft Gun Weapon Shooting Army Hunting Rifle Scope Kwy158-1X24 Gen 2 Night Vision]

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 (Custom Made Metal Stamping U Shape Holder Connecting Parts).Popular Medical Equipment 3 Function Manual Wholesale Hospital Bed, waste residue is inert and sterile, i.e., environment friendly,4-Wheel Folding Electric Mobility Scooter with 2019 New Design(95%) and mass (80%–90%).
