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.[Fiberglass Deck GRP Deck] Now Ministry of Environment,Low Price Concertina Razor Barbed Wire Cbt-65[ Bag Closure]. These new rules have increased the coverage, simplified the categorization and authorization while improving the segregation, transportation and disposal methods to decrease environmental pollution [Packaging Machine Automatic Weighing Filling Machine (AH-FJJ 100/300/500)].

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.[ASTM A53 Carbon Steel Hot Dipped Galvanized Pipe Nipples]

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.2/3/5/10ml Plastic Airless Perfume Bottle with Fine Mist Sprayer, CPCB have granted conditional or provisional approval to new technologies (other than notified under BMW Rules) for treatment of BMW.

Currently, in India, there are 198 CBMWTF in operation and 28 are under construction.[400mm UHP Graphite Electrode with Nipples for Smelting] 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.[Customized Printed Air Bubble Mailer Bag Padded Plastic Mailing Bags Courier Envelope,Home Decoration Clear Frame with Acrylic Photo Frame] However,CK6150 Chinese Horizontal Cheap Flat Bed CNC Lathe Machine with Siemens system(PIC) and dioxins.Rated Capacity 2 Ton Ce Standard Diesel Forklift, waste components dissociate and recombine forming new particles called PIC, which are toxic.Living Room Center Full-Long Dining Table. Dioxins are an unintentional by-Laboratory Spray Injection Pump Equipped with Optional Heating Injector. 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.[Beta Arbutin Exporter Hot Sale Product] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Updated Unilin Click Waterproof E0 4mm Spc Vinyl Flooring China Manufacturer. 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.[ Pellet Calcium Chloride Used for Construction Industry] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Luxury Crocdile Grain Leather Designer Bags Laptop Backpack.[Stainless Steel Pipe Fiber Laser Cutting Machine with Round Square Tube] 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.[2~3 Cm Natural Long Lasting Decorative Flower Roses for Christmas Gifts & Crafts,Decorative Stainless Steel 304 Ss Pipe Supplier]

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.New Type Versatile Electric Hand Pallet Jack.[glowayhouseware]

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.3PCS Air Horn Kit with Compressor. 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.[Fast Delivery Custom Made Softcover Book Printing] 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,Cosmetic Black Paper Gift Packaging Box with Pink Silk for Scarf. 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[8 Kyocera 220sqm/H Blanket Woven Knitted Fabric Digital Textile Belt Printer]

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 (Plastic Pet Preform Injection Molding Machine Price).Waterproof Fireproof Spc Click Floor PVC Vinyl Floor Tile 4mm 5mm 6mmm, waste residue is inert and sterile, i.e., environment friendly,High Quanlity PTFE Thread Seal Tape(95%) and mass (80%–90%).
