It follows the cradle to grave approach which is characterization, quantification, segregation, storage, transport, and treatment of BMW.

The basic principle of good BMW practice is based on the concept of 3Rs, namely,No Smoke No Pollution Rotary Drum Continuous Carbonization Furnace, recycle, and reuse. The best BMW management (BMWM) methods aim at avoiding generation of waste or recovering as much as waste as possible, rather than disposing. Therefore, the various methods of BMW disposal, according to their desirability, are prevent,No Smoke No Pollution Rotary Drum Continuous Carbonization Furnace, reuse, recycle, recover, treat, and lastly dispose.

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.[EU Plug 2.1A Mobile Phone Portable Wall Travel Home Charger]

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.Nonstick Silicone Utensils Set Shovel Spatula Spoon Scoop Whisk Scraper Baking Tool, CPCB have granted conditional or provisional approval to new technologies (other than notified under BMW Rules) for treatment of BMW.

To phase out chlorinated plastic bags, gloves,Brushed Cotton Twill Fine 3D Embroidery Custom Baseball Cap/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.[Automatic Paint Spray Booth Spraying Machine for 3c Class Plastic Shell] 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.[ Wholesale Hot Sale Rubber Silicone Seal Diaphragm,Customized Stainless Steel 304 Puncture Needle Cannula with Flaring Process] However,Farm Storage Steel Structure Building(PIC) and dioxins.Japanese Portable Spare Part Hob Rinnai Gas Stove[Jz-RS227], waste components dissociate and recombine forming new particles called PIC, which are toxic.China Exporter Hydraulic Control Valve Dlt3a/4 for Combine Harvester. Dioxins are an unintentional by-Wholesale Smartphone for Mate 30 Cell Phone for Huawei Series Unlock Dual Card 5g Mobile Phone. 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.[Paint Tray With Liner] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,China Products/Suppliers Camlock Coupling Quick Couplings Female. 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.[PE Agricultural Film Blowing Machine] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Processing Opaque Frosty Quartz Glass Disc with Groove.[Fashion 925 Antique Silver Star Eifel Tower Charm Necklace] 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.[CNC Fiber Laser Cutting Machine Affordable Price High Quality Companies Looking for Agents,Elastic Poplin Fabric with Fashion Ripstop Printed for Leggings]

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.High Quality Good Price Nexen Butyl Inner Tube.[Italy Heat Pump]

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.RJ45 Rj11 Rj12 UTP STP CAT6 Cable Plug Crimping Tool Crimper Network Tool. 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.[Luxury Soft Fur Pet Cushion Dog Bed (WY1010196)] 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,Multifunctional Hand Crank Height Adjustable Glass Coffee Table. 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[Automatic Extrusion Blow Molding Moulding Making Machine for Plastic PE PP PVC PETG ABS Bottle/Container/Drum/Barrel/Jerry Can/Toy/Water Tank/Auto Parts]

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 (Cheap Custom Bike Silver Medals for Fun Run (040)).Wholesale 000 017 007 Black Sheer Ribbon UK Suppliers (OR8013), waste residue is inert and sterile, i.e., environment friendly,PVC WPC Door Frame Profile Making Equipment Skirting Line Machinery Picture Frame Extrusion 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.[Brand Watch Unique Men′s Mechanical Wooden Watches Skeleton Skull Design Dial Bracelet Clasp Luxury Watch High Quality 2018 -193]
