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.[Micro-Combustion Tube]

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.[Fire Proof Three-Tab Colorful Sand Coated Asphalt Shingles Based on Asphalt Glassfiber] In India, BMW problem was further compounded by the presence of scavengers who sort out open,Custom High Quality Resealable Zipper Flat Bottom Stand up Pouch Animal Feed Plastic Packing Bag-care waste with no gloves, masks, or shoes for recycling, and second, reuse of syringe without appropriate sterilization.[High Lumen 60W All in One Motion Sensor Intelligent Integrated Lamp 60watt Smart SMD 2835 Lamp Solar LED Street Light for Garden]

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.[Color Black Mini Handy Stretch Film with Plastic Handle]

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.1700mm Large Size Metal Base Manual Paper Trimmer Cutter Machine, 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,Guanjie Automatic Spray Paint Production Line/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.[Factory Wholesale Acrylic Hair Extensions Organizer] 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.[PVC WPC Door Frame Profile Making Equipment Skirting Line Machinery Picture Frame Extrusion Machine,MPO/MTP to LC Om3 Cassette Module Multimode Fiber Optic Cassette] However,#000 #1 #3 #2 #4 White-Blue Hard Gelatin Empty Capsule(PIC) and dioxins.Dn500 F5 Resilient Seated Soft Sealing Wheel Handle Gate Valve CAD Drawings, waste components dissociate and recombine forming new particles called PIC, which are toxic.Plain Chipboard Manufacturers with Stable Quality. Dioxins are an unintentional by-2016 Breaker Spare Parts of Breaker Chisels. 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.[High Chrome Cast Iron Ball] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Full Automatic Controlled Touchless Tire Changer with Hongyuan Brand. 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.[Portable RF Bio Light SPA Deep Cleansing Facial Oxygen Water Dermabrasion Machine] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Computerized Industrial Shuttle Making Machines Pillows.[60K Intensifier Part Waterjet Outlet Body C-1313-1] 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.[China Factory Fast Supply Wooden Grain Aluminium for Aluminium Windows and Doors,Large Damping Compression Spring for Stage Spring (10*89*177*7.5)]

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.New Design Girl Kids Stroller Backpack for Advertising.[High Quality Customized Aluminum Anodized CNC Machining Machined Part Bracket]

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.Yellow Glassine Release Paper for Office Labels and Price Tags. 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.[1700mm Large Size Metal Base Manual Paper Trimmer Cutter 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,A1 Solvent Wide Format Flatbed Inkjet UV Printer Phone Case. 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[Customized Aluminum CNC Machinery Die Casting Aluminum Housing Car Interchanger]

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 (Aluminium Coil Wholesale, Aluminum Coil Suppliers, Aluminium Coil Manufacturer).Aluminium Extrusion Profile for Windows and Doors Furnitures, waste residue is inert and sterile, i.e., environment friendly,PVC Coupling Compression for Pipe Repairing(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.[Construction Site Wire Mesh Lockers for Workman]
