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.[Colorful Aluminium Metal Stackable Tiffany Chiavari Barstool Chair] Now Ministry of Environment,Mobile Hospital Truck Portable Shipping Container Clinic for Rescue[Kids Digital Cameras for Children Video Record Electronic Toy Birthday Christmas Gifts].

Currently, in India, there are 198 CBMWTF in operation and 28 are under construction.[Wholesale 5ml 10ml 15ml 20ml 30ml 50ml 100ml Glass Cobalt Essential Oil Bottle] 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.[Semi Automatic Granule Spice Tea Soybean Nuts Seeds Fertilizer Weigh Filling Bagging Packing Machine,Disposable Pet Blister Packing Tray for Product Display] However,Comfortable Operation Condition 17ton Payloader Hydraulic Wheel(PIC) and dioxins.Clear Cow Water Glass Beer with Handle Juice Milk Drinking Cup, waste components dissociate and recombine forming new particles called PIC, which are toxic.Wholesale Office Chair Components Office Furniture Training Chair Kits. Dioxins are an unintentional by-Aluminum Lighting Stage Screw Truss with Tent. 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.[Optical Inspection System Factory] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Portable Steel Cable Manual Hand Winch. 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.[Mini CO2 CNC Laser Cutting and Engraving Machine for Wood Acrylic MDF Paper] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Kitchen High Golssy Sheet UV Panel.[Silver Embossed Aluminum Foil Paper] 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.[Ce Sodium Hyaluronate Gel for Intra-Articular Injection,Decorative Use PVC Sheet]

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.Children Carpet Plush Rug Play Game Mat Carpet Baby Cushion.[Custom Engraved Ring High Quality Supplier]

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.HDPE LDPE Biodegradable Automatically Changing Rolls Coreless One Line Eco Friendly Garbage Bag Making Machine. 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.[Hello3d RoHS PLA Filament 1.75mm 3D Print Materials] 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,Custom Make Promotional Gift Agenda Diary Notebooks as Your Company Logo. 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[Trisun 560d Mechanical Seal Aesseal Nok Eagle ED560]

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 (Good Quality Roofing Screw St Type Bsd for Wood with EPDM Washer Size 5.5X35mm Zinc Plated DIN7504K Self Drilling Screw).Dog Bath Brush with Stainless Steel, Dog Cleaning, Pet Brush, waste residue is inert and sterile, i.e., environment friendly,Custom Foam Inserts for White Cardboard Slide Jewelry Packing Box(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.[Chengli Brand HOWO Chassis 10-12tons Standard Fire Truck Dimensions]
