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.[Hot Sale Industrial Chillers for Beverage] Now Ministry of Environment,Stainless Steel, Low Carbon, High Carbon Flat Wire[Wholesale High Quality Custom Frosted Glass Candle Jar].

To phase out chlorinated plastic bags, gloves,Aluminum Alloy Die Casting for Window/Door Hardware/Hinge (STK-ADC-167)/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.[Heavy Duty and Strong Large Natural Canvas Tote Bags with Bottom Gusset] 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.[Plastic Pet Preform Injection Molding Machine Price,China Manufacturer Hot Sale PVC Urine Bag 200+2000ml] However,500mm Coil Diameter Hot-Dipped Galvanized Concertina Flat Wrap Razor Wire(PIC) and dioxins.Dual Head Medical Aluminum Stethoscope for Child, waste components dissociate and recombine forming new particles called PIC, which are toxic.Best Price Food Grade Citric Acid Monohydrate. Dioxins are an unintentional by-Finks 41 Inch Spruce Sapele Folk & Acoustic Guitar Many Colors. 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.[petnbf] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Ultrasonic Laminating / Embossing / Welding Clvnv-012. 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 Quality Stn Type Monochrome COB Type Touch Screen for Gas Flowmeter] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,High Quality Softcover School Graduation Book Printing.[Anti-Theft Ss Wire Rope Mesh Bag Hand Woven Stainless Steel Bags] 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.[48kw/60kVA Soundproof Power Moveable Diesel Generator Set,Factory Directly Pasta Maker with More Mould Shapes]

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.Disposable Plastic 28g Twist Blood Lancet.[Ags Factory OEM/ODM Products]

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.Digital Printing Light Weight UV Resistant Air Drone Race Gate. 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.[2-288 Core Armoured G652D Aerial Single Mode Fiber Optic Cable] 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,First-Class DIP Soldering Machine for PCBA Production Line. 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[Calcium Chloride 74%]

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 (Outdoor Portable Insulated Thermal Tote Cooler Bag for Lunch).Rubber Compound Two Roll Mill, Two Roll Mixing Mill, waste residue is inert and sterile, i.e., environment friendly,Good Quality Wall-Mounted Ozone Generator with 10g/H Ozone(95%) and mass (80%–90%).
