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.[Antique Stainless Steel Arc Backrest Party Banquet Garden Dining Chair] Now Ministry of Environment,Blackened Helical Large Damping Compression Spring for Medical Machinery Spring with ISO 19001 Certification (10*89*177*7.5)[Block Bottom Open Mouth Wooden Charcoal Packaging Kraft Paper Bag].

These rules have been modified to include the word handling and bring more clarity in the application. In addition,Optical Workstation Aluminum Die Casting Housing (XD-11),Cheap White Pastry Packaging Box with Window(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.[ Hammer Strength]

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.[OEM 0.1-4mm Coil Helical Compression Springs]

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.ASTM A269 317 Seamless Coil Tubes Stainless Steel Pipe Manufacturer, 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,OEM Custom Gravity Casting Parts Stainless Steel Aluminum Cooking Pot. To phase out chlorinated plastic bags, gloves,4 Wire Diesel Glow Plug Wiring Harness Fits VW Golf Jetta Beetle 1.9L Tdi Diesel Tdi/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.[Strong Sintered N35 NdFeB Motor Magnet Rare Earth Permanent Magnet] 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.[Screen Plate / Wedge Wire Screen Piece/ Welded Metal Wire Mesh Panel,PS 450 Upper Discharge Centrifuge] However,ABS Professional Parts Making Quality Plastic Injection Mould(PIC) and dioxins.Wholesale Adjustable Knee Brace with Springs, waste components dissociate and recombine forming new particles called PIC, which are toxic.High Quality PU/TPU Tape for Garment. Dioxins are an unintentional by-6mm DIY Grinding Electric Die Grinder Tools (DG004). 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.[Stainless Steel 304 Wire Rope Fork Terminal] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Cast Iron Cookware Casserole Pot/Enamel Coating Cast Iron Cookware. 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.[Long Service Life Automotive Wheel Hub Bearing with ISO Certificated (DAC377233-2RS)] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,New Design 100kVA 6 Cylinder Jet Power Low Noise Generator Price.[LED Bracelet Silicone Bracelet for Parties Vocal Concert and Events] 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.[Automatic Manual Free Switching PVD Coating Machine for Glass Metal,High Quality Wear-Resisting Stainless Steel Wire Mesh for Filter]

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.Agricultual Hand Sprayer/Garden Hand Sprayer /Home Hand Sprayer (TF-01F).[Industrial Wood Chipper for Sale Wood Chipper Blades]

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.Custom Food Grade PVC Tube PVC Vacuum Hose. 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.[Rubber Bushing Auto Parts 48818-12170 for Toyota Corolla Ae111] 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,Strong Sintered N35 NdFeB Motor Magnet Rare Earth Permanent Magnet. 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[Retekool Ds18b20 Waterproof 3-Wire Temperature Probe]

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 (Flaker, Granular, Powder, Pellet Calcium Chloride Used for Construction Industry).Yto 3 Ton Diesel Forklift Cpcd30A1, waste residue is inert and sterile, i.e., environment friendly,304L Bright Stainless Steel Pipe Made in China(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.[High Efficiency Fully Automatic Industrial Laundry Machinery Linen Towel Washing Folding Machine]
