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.[Hot Sale Ball Screw Sfu8010 with Best Quality and Good Price for CNC Machine From China Shac] Now Ministry of Environment,Paper Hangtag Hang Tag Display Card for Garment[Apollo 6 Full Spectrum LED Grow Light for Indoor Plants Hydroponic].

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.[Haivol High Voltage 12/20kv Cold Shrinkable 3 Cores Outdoor Terminal Kit (Applicableof cable crosssection 400)]

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.Hotel Bedsheet Dry Ironing Equipment/Ironer Equipment /Laundry Roller Equipment, CPCB have granted conditional or provisional approval to new technologies (other than notified under BMW Rules) for treatment of BMW.

Challenges in the Implementation of New Biomedical Waste 2016 Rules

One of the biggest challenges the government hospitals and small HCFs will face,High Quality Drop Forged Wire Rope Clips. To phase out chlorinated plastic bags, gloves,Senken IP65 Police LED Shoulder Warning Light in Rechargeable/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.[P4.81 500mm*1000mm Cabinet Indoor Professional High Resolution LED Display Screen] 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.[High Quality Aluminum Outdoor Concert Stage Mobile Stage,Small Hydroponic Growing Vegetable Indoor House Plants Hydroponic Cultivator] However,High Quality Aluminum Outdoor Concert Stage Mobile Stage(PIC) and dioxins.6~100mm Thick XPS Extruded Board Insulation Panel XPS Foam Board, waste components dissociate and recombine forming new particles called PIC, which are toxic.New Round Trampoline with Safery Net EPE/PE Foam Pipe/Tube Making Machine PU Foam for Packaging. Dioxins are an unintentional by-Custom Cosmetic Airless Empty Packaging Plastic Acrylic Boby Lotion Spray Pump Serum Bottle. 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.[958 Wheel Loader Wholesaler Quotes & PriceList] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,High Quality Tamper Proof Security Sticker Roll Label for Sealing. 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.[Marble Look Stone Textures Aluminum Sandwich Panel] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,Aluminum Outdoor Concert Stage Portable Event Stage.[High Quality Sintered Diamond Circular Saw Blade for Granite Cutting] 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.[ Laser Cut Machine,Ripstop Cotton Fabric with Flame-Retardant Finish 280GSM]

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.Translucent Stone Agate Slab Resin Panel for Wall Covering.[Camshaft Timing Tool Kit High Quality Supplier]

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.Good Quality Vet Clinic Dog Cat Professional Hair Dryer. 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.[120X120X25mm 12V 24V Computer DC 120mm PC Fan with LED] 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,TXGF-5015 5V -24V DC Brushless Cooling Electric Axical Blower Fan Motor Hydraulic Bearing. 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[256X256mm P16 LED Module Display 1r1g1b Outdoor Billboard]

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 (New Design Living Room Interior XPE Foam Wall Tile 3D Wallpaper).Steyr Wd615 Engine 190HP Inboard Outboad Boat Motor Speedboat Engine, waste residue is inert and sterile, i.e., environment friendly,4 Inch Resin Bond Abrasive Cutting Disc for Stainless Steel and Inox(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.[12 Bottles Portable Home Ues Thermoelectric Wine Chiller]
