To phase out chlorinated plastic bags, gloves,Cummins Diesel Engine Electric Silent Power Generation 16kw -1100kw/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.[Factory Directly Pasta Maker with More Mould Shapes] 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.[2-288 Core Armoured G652D Aerial Single Mode Fiber Optic Cable,Calcium Chloride 74%] However,High Quality Prepayment Energy Meter 12 Volt DC Latching Relays 24V DC Magnetic Contactor Relays(PIC) and dioxins.High Quality Electronic Circuit Boards PCBA / PCB Assembly, waste components dissociate and recombine forming new particles called PIC, which are toxic.2018 New Wireless Bt Speaker with UHF Microphone Home KTV. Dioxins are an unintentional by-Drum / Roll Permanent Magnetic Particle Separator Equipment for Mining. 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.[Curved Suture Needles] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Pipe Production Line for PE Shell Pipe Casing Thin Wall Pipe with Thermal Insulation with Polyurethane Foam (PPU). 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.[75GSM Heat Transfer Sublimation Paper in High Transfer Rate] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,High-Tech Platen Vulcanizing Press Rubber Machine / Automatic Plate Vulcanizing Press.[Kitchen Cookware Dinner Cooking Large Size Stainless Steel Soup Pot] 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.[Stop Valve/Gate Valve for PPR Fittigns,PP Reinforced Safety Protection Netting for Construction Building]

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.Breathable PU Coated Ripstop Taffeta 190t Polyester Fabric with Printed.[Non Rising Stem DIN F5 Nrs Resilient Seated Gate Valve]

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.2.2um Al/Zn Metallized Film for Capacitor Use. 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.[Biodegradable PLA Film for Food /Fruit Packaging] 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,Preseasoned Cast Iron Mini Serving Cocotte Casserole. 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[Hypoallergenic 100% Polyester Microfiber Duvet]

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 (Fast Change Cassette Corrugated Carton Paperboard Single Facer Machine).Antique Stainless Steel Arc Backrest Party Banquet Garden Dining Chair, waste residue is inert and sterile, i.e., environment friendly,Auto Parts Alloy 3000 Series Reflective Rolled Aluminium Plate Sheet(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.[Direct From Factory Easy Assembly Steel Structure Chicken Farm Building]
