To phase out chlorinated plastic bags, gloves,Welding Electrode Price of Welding Rod E7018/E7016/E7015 Welding Electrodes Sea Bridge Brand/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.[Sublimation Bronze Metal Medal (JP50BR)] 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.[Poultry Slaughter Equipment for Chicken House Butcher Processing Machine,China Best Quality Nutritional Reconstituted Artificial Rice Machine] However,Silver Foil Stretchy Polyamide Elastane Knitted Fabric Dance Wear(PIC) and dioxins.Filter for Edible Oil Filtered Edible Oil Brands in India, waste components dissociate and recombine forming new particles called PIC, which are toxic.40X4 COB Character LCM Display, MCU 8bit, Stn LCD Module, FSTN LCM Panel. Dioxins are an unintentional by-DIN/ANSI/BS/JIS Carbon-Steel/Stainless-Steel Phillips/Slot Shaft of The British Flat Tail Screws. 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.[Wholesale Various Surface Finish Customed Aluminum Curtain Wall Profile] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,High Effective Good Quality Popular Dog Chews Machine. 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.[Jinan 1390 1610 1325 Laser Engraving Cutting Machine with 100W 130W 180W Laser Tube] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Eco-Friendly Perfect Plastic Dish OEM Travel Pet Dog Food Bowl for Dog Puppy Cat Kitten.[17 Languages Waterproof IP65 Biometric Network Fingerprint Access Control with ID Card] 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.[Ozone Water Production Equipment for Agricultural Irrigation,20W All in One Integrated Solar Street Light (BR-IT20W)]

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.Battery Pack Making Process Five Gear Automatic Battery Voltage/Current/Impedance Testing Grading Sorting Machine Twsl-500.[China Smart Home Switch]

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.2 Years Warranty 300W IP65 LED Floodlight for Sports Fields. 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.[Q1322 Plastic Pipe Screw Manual Pipe Thread Cutting Lathe] 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,PA66 Flat Yorn Braided Sleeving. 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[NPK Compound Fertilizer Making Machine]

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 (1 Fiber Single Mode Scapc Hoptic Connector Matching with Corning Optitap Connector).Custom Single Empty Blush Palette Packaging Private Label Makeup Cardboard Palette, waste residue is inert and sterile, i.e., environment friendly,Furniture Constructions Building Material PVC Foam Board(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.[100ml Clear Glass Beer Bottle Manufacturer Factory Price Supplier in China 1076]
