Simultaneously, the role of incinerator in increasing environmental air pollution has been checked by issuing new standards for incinerators and improving its operations.[Precision Custom CNC Machining Aluminum Router Car Parts Manufacturer]

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.[Factory SMD3528 60LEDs/M Flexible LED Strip]

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.UPVC Reducing Female Tee Fitting for Water Supply, CPCB have granted conditional or provisional approval to new technologies (other than notified under BMW Rules) for treatment of BMW.

Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,0.8mm Rigid Transparent Plastic PVC Sheet for Furniture Panel. To phase out chlorinated plastic bags, gloves,100W CO2 Laser Engraving Equipment for Wood/Plywood/Veneer/MDF/ Balsa/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.[China Wholesale Cheap Price Watermelon Seeds Kernels] 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.[Helical Shaft Mounted Gearbox Nmrv Series Gearbox Right Angle Cast Iron Worm Gearbox,New Hyundai Mini 7ton Hydraulic Crawler Excavator R75vs] However,2W 3W Motorcycle Tire Automatic Bom Hydraulic Curing Press Machine with Individual PLC(PIC) and dioxins.Raw Material Good Elastic Spandex Yarn for Baby Diaper, waste components dissociate and recombine forming new particles called PIC, which are toxic.Egg Packing Plastic Collapsible Crate Egg Crate. Dioxins are an unintentional by-Packaging Film Usage and POF Material Shrink Film Wrapping Thermal Heating Tunnel. 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.[9cm Best Selling Factory Wholesales Classic Steel Cheap Stainless Steel Travel Mug Cups] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Hot Sale High Quality Carbon Steel Rivet Nut. 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.[Magazine and Books Vending Machine with Auto Opened Door] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Wfs Series China Herb High Speed Grinder.[Kid Knit Winter Warm Indoor Slipper Boots] 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.[Low Fat and High Protein Peanut Butter Without Sugar and Without Salt,Top Quality Custom Composite Ice Hockey Stick]

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.FC Seris Rectangular Insustrial Exhaust Fan.[Epoxy Resin Impregnated Fiberglass Binding Tape]

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.Kids Education Games Plastic Funny Square Whack-a-Mole Toy. 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.[Wholesale Hotel 100 Cotton Yarn Dyed Stripe Swimming Beach Towel] 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,8X2.5 10p Portable Chop Saw Cutting Machine Safety Abrasives. 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[Precut Non-Stick Unbleached Parchment Cookies Baking Paper Liner Sheet]

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 (Cast Steel and Cast Iron Knife Gate Valve).Diesel Oil Filter Centrifuge for Humus Fertilizer Separation, waste residue is inert and sterile, i.e., environment friendly,Modified Plastics Pellet PA6.6GF25(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.[Air Logistics Freight Shipping rates from China to Kazakhstan Aktau(SCO)Airport reliable Forwarder]
