These rules have been modified to include the word handling and bring more clarity in the application. In addition,Air Ride Suspension Clean Crisp Cutting Air Hose Cutter,Promotional Gifts High Quality Plastic PP Foam Clipboards(CBMWTF). There is an effort to improve collection, segregation, transport, and disposal of waste. Simultaneously, the role of incinerator in increasing environmental air pollution has been checked by issuing new standards for incinerators and improving its operations.[ Pneumatic Punching Machine]

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.[A2-70 A4-80 Stainless Steel 304 316 Square Head Cage Nut]

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.New Condition Bread Crumbs Processing Line with Ce Certificate, CPCB have granted conditional or provisional approval to new technologies (other than notified under BMW Rules) for treatment of BMW.

To phase out chlorinated plastic bags, gloves,Polypropylene Needle Felt Non Woven Filter Cloth for Filter Press/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.[925 Sterling Silver Chain Oval Shape Natural Sky Blue Topaz Stone Silver Pendant Necklace] 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.[V Type Dry Powder Blender Equipment,Single Wall Corrugated Pipe Extruding Machine&Extrusion Machine&Extruding Line] However,Passport Holder Cover Not Genuine Leather Wallets Gift Sets Fashion Mini Handbags PVC Lady Purses for Women 30525(PIC) and dioxins.Cat Eyes Sunglasses with Metal Temple (M11510), waste components dissociate and recombine forming new particles called PIC, which are toxic.13 Pieces Thermometer Nasal Aspirator Nail Clipper Baby Care Kit. Dioxins are an unintentional by-PVC PP PE etc Rectangular Extruded Plastic Pipe for Industry. 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.[Plastic Liquid Soap Foam Dispenser Lotion Pump] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Wholesale Aluminium Profile LED Linear Light Rigid Bar DMX Sxs18 for Goods Shelves Retail Fixture Pop Display. 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.[79 in 1 Ratchet Screwdriver Bit Set Hand Tool Set] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Gauge Piezoresistive 4~20mADC Water Tank Liquid Hydraulic Customized Pressure Sensor MPM489.[Wq Series No-Clog Submersible Slurry Pumps Sewage Sand Dredge Pump] 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.[Air Ride Suspension Clean Crisp Cutting Air Hose Cutter,Dry Type Permanent Magnetic Roll Separator Cr Series with 16000GS High Intensity]

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.2017 Geyi Disposable Linear Stapler for Laparoscopic Surgery.[Industrial Diaphragm Pressure Gauge]

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.LED Lanyards for Kids Adults Keys Keychains Cell Phones Cameras. 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.[China Direct Factory Hoodies & Sweatshirts for Men] 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,Playground Slide Swing. 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[Multifunctional Hand Crank Height Adjustable Glass Coffee Table]

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 (Sports Rubber Flooring/Gym Rubber Tile/Sports Rubber Flooring).Color Coated Aluminum Metallized Pet Film, waste residue is inert and sterile, i.e., environment friendly,Stainless Steel DIN1587 Hex Domed Cap Nut for Car/Motor/Bicycle(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.[WiFi Remote Control Draw out Intelligent Air Circuit Breaker]
