Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,Color Fancy Paper Made Small Jewellery Box. To phase out chlorinated plastic bags, gloves,Custom Size Packaging Box for Cosmetic/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.[12.1 Inch Capacitive Touch Screen with Ili2302 Controller for Industrial Touch Monitors] 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.[18.5mm High Resolution 480TV Lines Butterfly Mini Security Car DVR Camera with BMW Connector,Integrated Package Sewer Treatment Plant Containerized UF Equipment] However,Jiaheng brand Prestressing single acting hydraulic cylinder 25 ton hydraulic cylinder for dump truck(PIC) and dioxins.Small Portable Air Water Purifier with Disinfection and Detoxification, waste components dissociate and recombine forming new particles called PIC, which are toxic.Large Outdoor Restaurant Tent Gazebo Tent. Dioxins are an unintentional by-Auger Filling Automatic Powder Filling Machine. 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.[www.blockmachinechina.com] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Stainless Steel 340 Hex Head Bolt 316 Hex Head Bolt. 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.[Opposed Light/Middle/ Heavy Duty Disc Harrow Trailed Disa Harrow] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Construction Equipment Mechanical Taper Thread Rolling Machine.[Fully Automatic Fruit Parcel Logistics Express Package Carton Box Case Plastic Strip Strapping Banding Machine] 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.[Cantilever Base MID Back Fabric Conference Visitor Chair,High Quality Professional Cleaning Paint Brush]

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.Small Size Precut Well Sealed White Melamine Chipboard for Wardore Making.[Black Masterbatch For Film]

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.0.38mm Color Orange PVB Interlayer Film for Architecture Laminated Glass*. 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.[4K HDMI V2.0 Switch 5X1] 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,Zinc Alloy Electric Key Card Hotel Door Lock with ANSI Quality Mortise. 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[New Mason Cup Frosted Drink Bottle Juice Glass Mason Jar]

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 (Elastic Hook & Loop Tape for Baby Diaper).Luxury Prefab Ready Made Economical Portable Tiny Home Modular House, waste residue is inert and sterile, i.e., environment friendly,Best Selling Disposable Plastic Dental Surgical Suction Tips Aspirator Tips(95%) and mass (80%–90%).
