Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,Super Soft Egyptian Cotton Quality Home Bedding Bedsheet Set. To phase out chlorinated plastic bags, gloves,Stainless Steel Hole Punching Machine/ CNC Perforation Machine/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 Supply High Quality Hyaluronic Acid CAS 9004-61-9] 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.[PP Cartridge Ultra Filter for Water Treatment in All Size,RFID Blocking Trifold PU Leather Lady Wallet with ID Window] However,Centrifugal Fans Electric Misting Cooler with Purify Air(PIC) and dioxins.200ml-500ml Clear Square Glass Jar with Metal Lid, waste components dissociate and recombine forming new particles called PIC, which are toxic.Wholesale Wide Neck PPSU Baby Feeding Bottles with Handle 150/240/330ml. Dioxins are an unintentional by-3D Work Table Portable Fiber Laser Marking Machine Engraving System Metal Logo Engraving. 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.[4ml Clear Glass Ampoule Pipe] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,C - Band 20dBm, 1 Port Output, DWDM Booster EDFA (FWA-1550D-20). 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.[Newest Design Hot Sale Fashion Lady Stone Zircon Copper Wedding Ring] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Portable 6L Colored Cosmetic Mini Fridge.[50 Inch All in One Wall Mounted Android Smart Tablet Kiosks Display Touch Screen with Eeti Controller] 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.[W1200*L1200mm Cutting Width Circular Foam CNC Cutting Machine,Customized Metal Case Machined Oil Seals]

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.7g Jacquard Knitting Machine (AX-132S).[thtransformer.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.1200X2400mm Toilet Floor Tile Kuching Wholesale Island White Onyx Stone. 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.[Aluminum/Aluminium Extrusion Alloy Anodized Radiator] 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,Fast Food Cargo Tricycle with PU Box (TR-2B). 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[Drive Shaft for Jmc 8-94134458-PT]

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 (2308 Aluminum LED Profile Channel for LED Strips).Supplier Cast Iron Non-Stick Frying Pan, waste residue is inert and sterile, i.e., environment friendly,Commercial Lighting 40W LED Corn COB Bulb Replacement 150 Mental Halide(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.[(Ready to ship) Needle Free Negative High Pressure Compatibility Infusion Needleless Y Connector]
