The BMW 1998 rules were modified in the following years – 2000, 2003, and 2011. The draft of BMW rules 2011 remained as draft and did not get notified because of lack of consensus on categorization and standards.[Wholesale Good Quliaty Silicone Coated Fabrics] Now Ministry of Environment,904L Stainless Steel Press Sheet with Hl Surface Finish[ 1100]. These new rules have increased the coverage, simplified the categorization and authorization while improving the segregation, transportation and disposal methods to decrease environmental pollution [Brush Roller Spray Vegetable Fruit Washing Machine].

Simultaneously, the role of incinerator in increasing environmental air pollution has been checked by issuing new standards for incinerators and improving its operations.[Natural Blue Lapis-Lazuli Chips 5X7mm Around 85cm Necklace]

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.[3 Inch Ceramic Bond Diamond Floor Polishing Pad Abrasive Tool for Stone and Concrete Grinding]

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.Automatic Super Power Feed CNC Horizontal Milling Machine with Taiwan Spindle, 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,Stainless Steel Swage Stub End Rigging Screw Closed Body Turnbuckle/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.[20W 30W Laser Engraving Machine Neje] 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.[Nordberg C110 C125 C140 Jaw Crusher Spare Parts Fixed / Swing Jaw Plate,Painted Structure Steel Light Prefabricated Workshop Building] However,High Purity Press-Sintered Tungsten Crucibles(PIC) and dioxins.SMT Juki LED Lights Pick and Place Machine, waste components dissociate and recombine forming new particles called PIC, which are toxic.Full Automatic Liquid Filling Machine. Dioxins are an unintentional by-Custom Medical Polish Stainless Steel Capillary Tube Supplier. 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.[Carbon Steel Welding and Laser Cutting Metal Part for Spare Part] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Hot! ! Medical ABS Emergency Crash Cart for Hospital Patient Treatment Trolley. 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.[ Nylon Frame Fixing Anchor] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Bar Counter Chair Deep Drawing Mould.[FTTH Fiber Optic Fusion Splicing Toolkit] 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.[Changing Room Easy to Clean Anti-Bacterial Hospital Patient Locker,Chicken Layer Cage Poultry Cage Chicken Cages]

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.Comfortable Elegant Small Passenger Lifts for Home Use.[Fast Heat Casting Iron Round Grill Pan Frying Pan]

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.Packing Storage Gift Packaging Jewelry Box. 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.[Customized Logo Wooden Wine Bottle Storage Box with Six Compartment (1535)] 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,Synthetic Fiber Primary Bag Filter. 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[Customized Sand Casting Fitness CNC Machinery Part]

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 (ADSS Newest Ultra Therapy Skin Tightening 3D Hifu).Tungsten Carbide Wire Thread Dies for Galvanized Metal Sheets, waste residue is inert and sterile, i.e., environment friendly,Chinese Factory Direct Selling 430 Stainless Steel Strip(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.[Lohas Dimmable LED Grow Light Bulb 90-130V 180-240V E27 12W PAR30 Grow Lamp for Hydroponics Factory Nursery]
