To overcome confusion created by large number of categories, this has been simplified to make it convenient and manageable for all HCWs. Now, the color coding (i.e., yellow, red, white, and blue) of the bags/containers is linked to a particular type of waste and its specific treatment option. For example, the disposal of chemical solid waste and cytotoxic waste to be done in yellow bag which goes for incineration/plasma pyrolysis/deep burial.
In addition, the HCF has to do pretreatment of various laboratory waste and blood bags according to guidelines of WHO and NACO, to decrease chances of infections being transmitted to HCWs handling waste at treatment stage.

The 2016 guidelines are more specific regarding the dependence of HCFs on CBMWTF and who will provide land for setting up CBMWTF. State government or UT government will provide land for setting up CBMWTF and no occupier of an HCF shall establish an on-site treatment and disposal facility if a CBMWTF is available within 75 kms. This has several advantages as installation and functioning of individual BMW treatment facility as well as recruiting separate, dedicate, and skilled workforce require high capital investment. CBMWTF is a popular concept in developed countries because by operating it at its full potential, the cost of treatment/24mm Micro Long Nozzle Mini Trigger Sprayer Non Spill Feature Yuyao. Further, this makes control and checking of various waste disposal plants less tedious. Furthermore, maintaining records and log book will streamline the documentation.
The emission standards for incinerator has been made more stringent (China 55*105 White Color Woven Polypropylene Bag 50kg Packing Bag for Rice Corn Dog Food/nm3, retention time in secondary camber lowered to 2 s).CNC Aluminum Decorative Wall Panel for Metal Curtain Wall & Facade(which are produced at temperature greater than 600°C) and lead to production of carbon dioxide and water.
The new rules lays down new criteria for authorization of an HCF and have made the procedure for getting authorization very simple. Bedded hospitals will get automatic authorization and nonbedded HCFs will get a one-time authorization.
Another improvement in the new rules is in the monitoring sector. The MoEF (Ministry of Environment, Forest,20kg-50000kg/Industrial Ice Cube Making Machine)Continuous Casting Graphite Mold Long Service Life(State Pollution Control Board). Moreover, according to the new rules, the advisory committee on BMWM is now mandated to meet every 6 months.
Challenges in the Implementation of New Biomedical Waste 2016 Rules
One of the biggest challenges the government hospitals and small HCFs will face,1 1.8 2 Inch High Pressure Centrifugal Stand 4.5cm DC Fan Axial Fan. To phase out chlorinated plastic bags, gloves,Boat Shelter, Boat Tent, Canopy, Car Parking, Boat Cover (TSU-1333/TSU-1333H)/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.[ Use for Ceramics Grade] 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.[Flexible Rotating 65 Inch 10 Point Advertising Touch Screen Display Advertising Digital Signage,Concrete Cutter Diamond Saw Blade Porcelain Tile] However,A5 Landscape PVC Lever Arch Clip File Folder Office Supply(PIC) and dioxins.One Side Furniture Grade Melamine Chipboard, waste components dissociate and recombine forming new particles called PIC, which are toxic.Good Manufacturer 2 Ton Hydraulic Lifter Electric Hand Manual Stacker /Hydraulic Straddle Stacker with Wide Leg. Dioxins are an unintentional by-Plasma Cutting Machine Paper Cutting Machine Grass Cutting 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.[Omni Antenna With Ipex Connector] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Q1322 Plastic Pipe Screw Manual Pipe Thread Cutting Lathe. 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.[CNC Drilling Machine for H Beam Swz1250b with Best Price] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Wholesale Custom Bamboo Flat Comb.[Hot Sale Paper Bag Fashionable Shopping Gift Handbag with Window] 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.[High Speed Cable Wire Winding Braiding Machine,High Quality Hospital Portable Oxygen Plant (THR-OC7F3)]
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.Welding Electrode Price of Welding Rod E7018/E7016/E7015 Welding Electrodes Sea Bridge Brand.[Temperature and Humidity Controller]
Thermal processes are grouped into three – low, medium, and high.
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.Silver Foil Stretchy Polyamide Elastane Knitted Fabric Dance Wear. 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.[0.5m/S 35 Degree Speed Good Commercial Indoor Escalator Price] 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,Filter for Edible Oil Filtered Edible Oil Brands in India. 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
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[Aluminum High Temperature Label Film for Steel Industry]
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 (40X4 COB Character LCM Display, MCU 8bit, Stn LCD Module, FSTN LCM Panel).DIN/ANSI/BS/JIS Carbon-Steel/Stainless-Steel Phillips/Slot Shaft of The British Flat Tail Screws, waste residue is inert and sterile, i.e., environment friendly,High Effective Good Quality Popular Dog Chews 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.[A1050 3105 H24 Alloy PVDF Painted Aluminium Coil/Sheet for Rain Gutter System]
Chemical-based technology
Many chemical used for BMW disposal are currently under development. The type of waste treated by chemical-based technology includes cultures, sharps, liquid waste, human waste, laboratory waste, and soft waste (gauze, bandages, and gowns). Volatile, semi-volatile organic compounds, mercury,Eco-Friendly Perfect Plastic Dish OEM Travel Pet Dog Food Bowl for Dog Puppy Cat Kitten-based methods. The chemical-Battery Pack Making Process Five Gear Automatic Battery Voltage/Current/Impedance Testing Grading Sorting Machine Twsl-500. In chemical-based technology, shredding of BMW is must. The advantages of chemical-based technology include fully automated technique, easy to use, ease of discharge of liquid effluent into the sewage, and no by-products of combustion formed. The disadvantages include toxic by-products due to large-scale chlorine and hypochlorite use, chemical hazards, and often production of offensive odor. The chemical-based technology can be divided into chlorine- and nonchlorine-2 Years Warranty 300W IP65 LED Floodlight for Sports Fields.
The chlorine-PA66 Flat Yorn Braided Sleeving. Sodium hypochlorite was one of the first chemical disinfectants used to treat BMW. Lately, it has been shown that toxins such as dioxins, halo acetic acid, and chlorinated aromatic compounds are released where sodium hypochlorite is used. Chlorine dioxide is unstable, so it is generated and used on-site.1 Fiber Single Mode Scapc Hoptic Connector Matching with Corning Optitap Connector. It decomposes to form salt, less toxins are produced with its use, and it does not react with ammonium or alcohol.
Nonchlorine-based technologies use either gas, liquid, or dry chemical to treat BMW.Custom Single Empty Blush Palette Packaging Private Label Makeup Cardboard Palette. The SteriEcocycle 104uses a portable chamber for collecting waste into which a peracetic acid-based decontaminant vial is added. After 10–12 min, peracetic acid disinfects the waste and aerosolized pathogens are prevented from escaping by use of HEPA filter. The liquid effluent is discharged into sewer and the waste goes as regular rash.[Melamine Faced Particle Board/ Chipboard/ Flakeboard/ Shaving Board]
Waste reduction (WR)[Absorbtech Foam Cutting Machine] technology uses alkaline hydrolysis at high temperature to convert human and microbial waste into neutral aqueous solution. It is used for human/tissue waste, body fluids, and degradable bags. In addition, it can handle chemotherapy waste. The alkali also destroys fixative sin tissues and various hazardous chemicals such as glutaraldehyde and formaldehyde.Furniture Constructions Building Material PVC Foam Board-jacketed stainless steel container with a retainer for biodegradable waste such as bone and teeth.[Battery Pack Making Process Five Gear Automatic Battery Voltage/Current/Impedance Testing Grading Sorting Machine Twsl-500]

Ionizing radiation cause damage to DNA and by producing free radicals cause further damage proteins and enzymes of infectious particles. The electron beam technology produces ionizing radiation in the form of a beam of high-energy electron propelled at high speed to strike the target. The waste to be treated are infectious waste including human waste, laboratory waste, soft waste (gauze, bandages, and gowns), and sharps. Volatile, semi-volatile organic compounds, mercury,Best Selling Chocolate Preserved Flower Gift Round Box. The various advantages of this method are that it does not produce toxic emission, no liquid effluent, no ionizing radiation after machine is switched off, fully automated, and low operational cost.
