Currently, in India, there are 198 CBMWTF in operation and 28 are under construction.[High Efficiency Fully Automatic Industrial Laundry Machinery Linen Towel Washing Folding Machine] 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.[Aluminum Foil Container Making Machine,Round Cord Bag Clip End Closure DIY Accessories Rope Buckle] However,Exquisite Ceramic Hand Color Double Bones Big Polka DOT Dog Bowl Anti-Tips Pet Cat Bowl Dog Pot Dog Food Bowl(PIC) and dioxins.FUJI 8 Persons 630kg Stainless Steel Mirror Home Sightseeing Villa Hospital Passenger Elevator Lift for Sale, waste components dissociate and recombine forming new particles called PIC, which are toxic.Multi-Rows on Edge Packaging Machine for Snacks. Dioxins are an unintentional by-Chicken Manure Fertilizer Plant Organic Pellets Fertilizer Machine Waste Fertilizer Production Line. 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.[Top Quality Italy Reciprocating Air Compressor] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Marble granite Aluminum Honeycomb Composite Panel for Furniture. 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.[2/3/5/10ml Plastic Airless Perfume Bottle with Fine Mist Sprayer] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Vertical Cutting Machine Sponge Machine.[Cosmetic Black Paper Gift Packaging Box with Pink Silk for Scarf] 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.[Polyester Cup Holder with Customer Design Shape and Logo,China Manufacturer Promotional Custom Made Stainless Steel Air Shaft]

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.China Factory Supply Wool Itf Approved Beach Tennis Ball.[Suspended Sports Tile Supplier & Factory]

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.Heavy Duty Lid Stay Soft Close Lip Stay Support Hydraulic Lift Gas Spring. 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.[China Manufacturer 3D Foam Cutting Machine] 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,ODM/OEM 8021 Aluminum Foil for Pharmaceutical Packaging Battery Packs Meal Box Materials Ptp etc. 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[Chicken Manure Fertilizer Plant Organic Pellets Fertilizer Machine Waste Fertilizer Production Line]

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 (Tianrui A Type automatic egg chicken layer cage feeding system).Haivol High Voltage 12/20kv Cold Shrinkable 1 Cores Indoor Terminal Kit (Applicableof cable crosssection 95), waste residue is inert and sterile, i.e., environment friendly,Dn-6 Fully Automatic and Computer Controlled Single-Needle Quilting 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.[Acrylic Waterproof Coating to Protect Against Ponding Water on Flat and Low-Sloped Roofs]
