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.[MC4 Connector Male and Female] Now Ministry of Environment,China Manufacture Smart-Mfr Supply Key Shell for BMW Mini Cooper Aluminum Smart Remote Key Cover Shell[Comfort Home Indoor Scent Aroma Machine Silent Essential Oil Diffuser].

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.[PLC Servo Piston Liquid Bottle Oil Detergent Shampoo Disinfectant Bleaching Soap Cleaner Corrosive Bottling Filling Machine]

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.High Intensity High Gradient Magnetic Roller Separator, 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,ISO Approved Self-Cleaning Permanent Belt Magnetic Iron Ore Separator. To phase out chlorinated plastic bags, gloves,8.5 Inch Xiaomi M365 Long Range Folding Electric Scooter/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.[Medical Hospital Equipment Hydraulic Electric Hoist Lifts] 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.[OEM Packaging Machine Manufacturer Automatic Triangle Bag Packing Machine,with Screw Nylon66 Saddle Type Cable Clip Cable Tie Mounts] However,China Supply Corrugated Metal Steel Roofing Plate(PIC) and dioxins.OE. 55020-06j00 Auto Parts Rear Coil Spring for Patrol Gr I (Y60, GR), waste components dissociate and recombine forming new particles called PIC, which are toxic.Stainless Steel Crimped Wire Mesh. Dioxins are an unintentional by-Am3 Hot Galvanized Ship Anchor Chain for Sale. 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.[Aluminium Profile Curtain Wall with Decoration Home] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,8 Kyocera 220sqm/H Blanket Woven Knitted Fabric Digital Textile Belt Printer. 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.[Outdoor Waterproof Adjustable Wall Garden Lighting (KA-G702/B)] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Packing Box Plastic Moving Tote Bins with Lid.[Trendy Car Shape Cute Kids Trolley School Bags] 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.[Ductile Iron Grooved Fire Fighting Fitting,Decorative Metal Garden Fence Decorative Aluminum Laser Cut Metal Panel Exterior Wall]

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.Motorcycle Front/Rear Turn Signals Lm-321 E4 CCC Certification.[bentengcorp.com]

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.Climatic Cycling Stability Testing Chamber Temperature Humidity Cabinet. 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.[Food Powder Pouch Printing and Packaging Production Line] 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 Zinc Alloy Button Bracelet Outdoor Emergency Lifesaving Bracelet. 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[Crude Powder Mixer Machine in Pharmaceutical Industry]

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 (Chili Powder Pouch Packing Machine).Plastic Food Storage Container Box Sets, waste residue is inert and sterile, i.e., environment friendly,Hot Sale Women Grey Materntiy Longline Hoodies Wholesale Factory(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.[Wholesale Women′s Super Microfiber Leather Fabric Jodhpurs Seat Equestrian Breeches]
