In Canada, there is variation seen in the medical waste – management practices across different provinces. Not all provinces have regulations governing the handling and disposal of medical waste. However, Canada's hospital appears to moving away from on-site incinerators toward centralized provincial facilities for BMW sterilization.[Shenzhen Bakeware Supplier Metal Cake Baking Molds]

Biomedical Waste Situation in India

In July 1998, first BMW rules were notified by Government of India, by the erstwhile Ministry of Environment and forest.[Security 13.56MHz MIFARE DESFire EV1 2K/4K/8K  Rewearable Silicone RFID Bracelet Wristband] In India, BMW problem was further compounded by the presence of scavengers who sort out open,Ep250 Heavy Duty Rubber Conveyor Belt From Shandong Province, China-care waste with no gloves, masks, or shoes for recycling, and second, reuse of syringe without appropriate sterilization.[Acrylic with Vinyl Face Letter Sign]

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.[Motorcycle Parts Engine Carburetor for Cbf150 Chian Manufacture]

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.Wholesale Cheap Lab PU Injection Outsole Safety Shoes, CPCB have granted conditional or provisional approval to new technologies (other than notified under BMW Rules) for treatment of BMW.

In addition, every 6 months, this committee shall submit its report to the State Pollution Control Board.

Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,Double Jacketed Cooking Kettle Electric Jacket Boiler. To phase out chlorinated plastic bags, gloves,High Speed Centrifugal Spray Drier (LPG-200)/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.[Pet Sleeve Shrinking Label /Hot Pet Shrink Label Heating Roll Label Film in China Factory] 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.[Chicken Paw/Wing/Leg/Meat Weight Sorter with Low Price,Wfj Series Fine Pulverizer Grinder Unit] However,MID Clamp/End Clamp/ Base/ Holder/ Connector of Solar PV Mounting System(PIC) and dioxins.Personalized and Customized Fracturing Acidification Clay Stabilizer, waste components dissociate and recombine forming new particles called PIC, which are toxic.Automatic Sachet Pouch Bag Coffee Powder Tea Packing Packaging Machine. Dioxins are an unintentional by-500ml/1000ml Clear Kombucha Beverage Cold Brew Coffee Glass Bottle. 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.[Double Deck Roll Forming Machine] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,High Voltage 20kv 22kv 24kv Dry Type Isolation Transformer 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.[10W Outdoor Solar LED Floodlight Lamp Waterproof Flood Light] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,High Power Digital Ultrasonic Plastic Soldering Equipment for Filter Bag Welding.[Aluminum Screen High Building Facade Aluminum Window Louver] 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.[IP65 25W Outdoor Pure White Light LED Solar Street Lamp,Car Auto Spare Parts Auto Parts Fuel Pump Price 1j0919051b]

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.Ready Made Prefabricated House (pH-86).[Baby Ride On Toy Car Jeep High Quality Supplier]

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.Trisun 560d Mechanical Seal Aesseal Nok Eagle ED560. 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.[HSS Straight Sleeve Ejector Pin] 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,Factory Direct Supply Breathable Stripe Tc Shirt Cotton Fabric Material. 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[GSM Series Antenna Customized Connector Flat GSM Antenna]

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 (Anti-Corrosion Anti-Skid FRP Floor Moulded Grating 38*38*25mm Manufacture).Agricultural Machinery Manure and Urine Solid-Liquid Separator Manure Dewatering Machine, waste residue is inert and sterile, i.e., environment friendly,Galvanized Scaffold Thread Tie Rod for Formwork Construction(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.[Coil Tube 304 Grade Stainless Steel Manufacturer]
