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.[EVA PVC TPR Sole Twin Screw Plastic Granules Making Machine]

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.[Black White Thermal Break Aluminum Window] In India, BMW problem was further compounded by the presence of scavengers who sort out open,Zinc Galvanized Allen Drive Flat Head Self-Tapping Screws-care waste with no gloves, masks, or shoes for recycling, and second, reuse of syringe without appropriate sterilization.[Disposable PVC EVA Anesthesia Ventilator Breathing Circuit]

Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,Battery Pack Making Process Five Gear Automatic Battery Voltage/Current/Impedance Testing Grading Sorting Machine Twsl-500. To phase out chlorinated plastic bags, gloves,2 Years Warranty 300W IP65 LED Floodlight for Sports Fields/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.[Hot Sale High Quality Carbon Steel Rivet Nut] 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.[SUS304 Ba Polished Hot/Cold Rolled Stainless Steel Coils 201,Casting Timone Cultivator Point/ Blade for Agricultural Machinery Tillage Use] However,PA66 Flat Yorn Braided Sleeving(PIC) and dioxins.1 Fiber Single Mode Scapc Hoptic Connector Matching with Corning Optitap Connector, waste components dissociate and recombine forming new particles called PIC, which are toxic.Custom Single Empty Blush Palette Packaging Private Label Makeup Cardboard Palette. Dioxins are an unintentional by-Furniture Constructions Building Material PVC Foam Board. 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.[Beauty Mask] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Sany 60 Tons Stc600s Hydraulic Crane Project Truck Crane. 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.[16mm Rotary Potentiometer with Switch Carbon Potentiometer B10k B100k] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Best Selling Chocolate Preserved Flower Gift Round Box.[Ppap Level 3 Semi-Tubular Brass Flat Head Countersunk Head Rivets] 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.[IMTEK High Precision and Rigidity Linear Guides for CNC machinery,Compressor Safety Valve for Pressure Reducing]

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.Easy Foldable Kids Walking Chair Toys Baby Walker.[Wevi Large Clear Glass Straight Sided Jar with Lid]

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.Polymer Modified Cement Waterproofing Mortar. 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.[PVC Synthetic Leather / PVC Sofa Leather] 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,Hight Quality One-Step HCG Rapid Test Kits Pregnancy Test. 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[Wholesale Good Quliaty Silicone Coated Fabrics]

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 (Small Sheet Metal Fiber Laser Cutting Machine for Ss (750W)).Industrial Zirconia Zro2 Ceramic Wahl Electrical Hair Clipper Blade for Barber Shop, waste residue is inert and sterile, i.e., environment friendly,Polystyrene (EPS) Disposable Take-Away Containers Forming Machine(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.[ 1100]
