Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,3D Ball LED Christmas Decorative Motif Light. To phase out chlorinated plastic bags, gloves,Sanitary Ware Toilet Brass Angle Water Pipe Valve/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.[ LED Lighting] 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.[Laser Segmented Diamond Saw Blade for Stone Cutting,Catering Equipment 4 Burners Gas Stove Gas Cooker with Cabinet] However,OEM Universal Nylon 3 In1 Aluminum Alloy Fast Charging and 3 in 1 Cable for iPhone for Samsung(PIC) and dioxins.Large Diameter Pipe Galvanized Hot Steel Corrugated Culvert, waste components dissociate and recombine forming new particles called PIC, which are toxic.One Arm Motorized Multifunction Hospital Equipment for China Supply. Dioxins are an unintentional by-Hydraulic Rock Breaker Hammer to Break Rocks. 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.[Kitchen Plastic Spice Rack Organizer with 4 Drawers and a Knife Shelf] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,LC mm Om3 Duplex Optical Fiber Jumper Fiber Optic Patch Cords. 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.[PCB Fabrication Company PCBA Manufacturer SMD SMT Assembly] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,High-Quality HRC55 Carbide Thread CNC Machine Milling Tool.[Calculator Silicone Membrane Keypad Lenses with Connectors] 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.[Crystal Super Clear BOPP Packing Tape with Solvent Based,Metal Trapezoidal Roof Sheet Roll Forming Machine for Roof Panel]

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.Powder Coated Steel Fence Panel, Residential Fence, Garden Fence.[Flange Type Strainer]

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.60V 20A AC DC Charging Power Supply for Energy Storage System. 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.[Plasitc Anthurium Flower Decoration Hotel Room] 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,Pn10 Pn16 Class125 Motorized Butterfly Valve. 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[18 Ports Sc/APC Fiber Optic Connector Polishing Jig Fixture Holder]

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 (Metal Shell and Acrylic Neon Sign for Window).Memory Foam Pillow Top Mattress (8341#), waste residue is inert and sterile, i.e., environment friendly,China Supplier with Color Point Happy Birthday Number Candle(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.[2018 Good Sales Children Bicycles D1803]
