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.[Modern Design Steel Structure Broiler Chicken Ground System] Now Ministry of Environment,Teen Children Baby Wear Upf 50+ Sun Protection Swimming Clothing Long Sleeve One Piece Swimsuit with Zipper[Factory Price Peristaltic Hose Pump for Textile Mill]. These new rules have increased the coverage, simplified the categorization and authorization while improving the segregation, transportation and disposal methods to decrease environmental pollution [Aluminum Alloy Die Casting for Window/Door Hardware/Hinge (STK-ADC-167)].

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.[Chinese Manufacturers Precision Casting Hard Alloy Extrusion Mold]

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.18mm Red Oak Green Core Chipboard, 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,EVA Foam Cutting Machine for Packaging Protection Material Patterm Cutting Dieless Automatic CNC Ce. To phase out chlorinated plastic bags, gloves,1308/1308k Machine Tool Self-Aligning Ball Bearing/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.[T Type Thermal Break Strip] 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.[Wholesale From China Conveyor Belt Machine and Steel Cord Conveyor Belt,Airlock Valve -B] However,Ve Head Rotor for Citroen - Bosch Injector Pump Parts(PIC) and dioxins.Stainless Steel Sanitary SMS Pipe Fittings Union (JN-UN2002), waste components dissociate and recombine forming new particles called PIC, which are toxic.Cast Iron Bucket/Sand Casting Basin/Ductile Iron Casting. Dioxins are an unintentional by-Hc-10t Heavy Duty Big Cable Terminal Cable Lug Crimping Machine Crimper. 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.[Industrial Abrasives Alumina Ceramic Tube Pipe Supplier] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,No Smoke Biomass Corn COB Carbonization Kiln Price. 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.[Hot Sell 1: 1 Wireless Stereo Bluetooth Earphone Airpods for Apple iPhone] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Double& Single Faced Tube Storage Cantilever Rack System with 500kg~1200kg.[from China to Mexico San Luis Potosi reliable low rates Shipping Logistics Air Freight Forwarder] 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.[5050 Flexible IP67 Silicone Tube LED Strip,Kids Education Games Plastic Funny Square Whack-a-Mole Toy]

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.Hot Rolled 304 316 (304L 316L) Stainless Steel Plate/Sheet Price.[Hormones Hexarelin 99.7% Purity Anabolic Peptides Hexarelin]

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.Anatase Titanium Dioxide TiO2 for Paint and Coating La101. 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.[High Frequency Automatic Straight Seam Water Pipe Welding Machine] 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,Adjustable Neck Brace /Rigid Plastic Cervical Collar with Chin/Cervical Support Strap. 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[3D Modern Brick Interior Wallpapers 3D Paper Wall Decoration]

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 (250VAC Push Plinger Waterproof Mini Limit Switch).OEM Factory Commercial Automatic Stainless Steel Big Ice Cube Making Machine, waste residue is inert and sterile, i.e., environment friendly,304 Stainless Steel Staircase Armrest Fittings Shell Cover Foshan(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.[Qingdao Us Type Load Binder Lever Chain Tensioner]
