Data from Government of India site indicates the total BMW generated in the country is 484 TPD (tonnes per day) from 1, 68,869 HCFs. Unfortunately, only 447 TPD is treated, and 37 TPD is left untreated. There are 198 CBMWTF in operation and 28 under construction. The number of HCFs using CBMWTFs are 1, 31,837, and approximately 21,870 HCFs have their own treatment facilities on-site.[Industrial Graphite Mould]

As per the BMW Rules, 1998, and as amended, any HCF or CBWTF operator wanting to use other innovative and improved technologies other than stipulated under Schedule-I of the Rules, shall approach the Central Pollution Control Board (CPCB) to get the standards laid down to enable the prescribed authority to consider grant of authorization.Hot Sale 3D Glass Printing Machine, CPCB have granted conditional or provisional approval to new technologies (other than notified under BMW Rules) for treatment of BMW.

Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,Ce RoHS Ozone Generator Fruit and Vegetable Washer. To phase out chlorinated plastic bags, gloves,Formwork Accessories Galvanized Wing Nut for Construction/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.[DIN PVC Pipe Fitting Drainage Plastic Floor Drain Cover] 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.[Automatic Chicken Water Nipple Drinking System From Factory,Libya Steel or Iron Stainless Door Hardware Ball Bearing Hinge] However,Tab Terminal Waterproof Toggle Switch(PIC) and dioxins.Factory Custmized Produce Hanging Colorful Advertising Neon 3D Sign, waste components dissociate and recombine forming new particles called PIC, which are toxic.Disposable Underwear Beauty Salon Special Bath Sweat Sauna Travel Paper Underwear Men and Women Non-Woven Briefs (jt-016). Dioxins are an unintentional by-Cheap Primer MDF Ceiling Crown Molding Flooring Accessories Made in China. 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.[Biodegradable Eco-Friendly Nature Reusable Bamboo Travel Cutlery Set] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Customized Plastic Beer Crate Mould with 24 Bottles. 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.[Tesa 4965 Multiple Color Strip Lights SMD LED Strip] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,CNC Turned Plastic Delrin POM Parts Machining.[MID Clamp/End Clamp/ Base/ Holder/ Connector of Solar PV Mounting System] 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.[3/8Super Flexible Cable Low Smoke Halogen-Free Fire-Retardant RF Feeder Cable Coaxial Cable,Customized 2/4/6 Layers Flexible Circuit Board PCB Factory]

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.P4.81 500mm*1000mm Cabinet Indoor Professional High Resolution LED Display Screen.[Charms for Jewelry Making (Sold Per Bag 10PCS Inside)]

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.Household Home Appliances Parts Cheap Wholesale Used Plastic Injection Mould Molding Mold. 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.[IP66 15-100W Recessed LED Downlight 5 Years Warranty] 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,2019 Hot Sales Duplicator Garage Door Opener Keychain. 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[Plastic Portable Folding Platform Cart/ Flat Folding Wheel Dolly/ Collapsible Wheel Trolley]

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 (Precision Low Pressure Aluminum Alloy Die Casting Part).1kVA~500kVA Modular/Static/Low Frequency Power Supply Online UPS, waste residue is inert and sterile, i.e., environment friendly,Small Size Laser Engraving Machine, High Speed Laser Cutting 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.[ High Purity]
