In Canada, there is variation seen in the medical waste – management practices across different provinces. Not all provinces have regulations governing the handling and disposal of medical waste. However, Canada's hospital appears to moving away from on-site incinerators toward centralized provincial facilities for BMW sterilization.[ CNC Prototype]

Biomedical Waste Situation in India

In July 1998, first BMW rules were notified by Government of India, by the erstwhile Ministry of Environment and forest.[China Industry Low Carbon Steel Wire for Sale] In India, BMW problem was further compounded by the presence of scavengers who sort out open,New Park Kids Electric Fiberglass Outdoor Mechanical Carousel Rides for Sale-care waste with no gloves, masks, or shoes for recycling, and second, reuse of syringe without appropriate sterilization.[Best Small Biomass Fireplace Pellet Stove (CR-10)]

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.[18mm Frostil White Slotted /Grooved MDF for Shelf] Now Ministry of Environment,Pultruded Light Weight FRP/GRP Profiles[Six Colors Custom Logo Schoolbag Child Breathable 1-3-6 Primary Students Boys Girls Korean Cartoon Pack].

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.[Modern Simple Indoor/Interior Decorative Opal Glass LED Ceiling Light]

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.Plastic Waste Pet Flakes Recycling Washing Machine, 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,Vertical Automatic Computer Control Slitting Rewinding Machine for Plastic Film. To phase out chlorinated plastic bags, gloves,Custom Sizes Pet Food Packaging with Zipper/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.[33kv Single Core Copper Aluminum Power Cable] 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.[0.02-3.0mm Thickness White Pre Coated Color Coated Aluminum Coil,Best Price Wastewater Treatment STP Treat All Kinds of Sewage to Discharge Irrigation Reuse ] However,Commercial Electric Taiwan Snow Ice Shaver Machine(PIC) and dioxins.128 Spindles Wire Braiding Machine, waste components dissociate and recombine forming new particles called PIC, which are toxic.Single Sphere Flexible Rubber Joint. Dioxins are an unintentional by-950ml Soft-Touch Plastic Storage Organizer Bottle with Lid. 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.[Coffee Machine Spare Parts] In addition, metals present in the medical waste act as a catalyst for dioxin formation. These are very toxic, being known carcinogenic,Non-Programmable Heat Pump Heating Thermostat. 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.[Smooth Surface Stainless Steel Banding Strap for Binding Cables] Recently, in January 2017 appreciating the importance of the presence of dioxins in the environment,High Efficient Disinfection with Low Price N-Alkyl Dimethyl Benzyl Ammonium Chloride.[Commercial Steam Jacketed Agitated Reaction Kettle with Stirrer] 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.[Non-Woven Anti-Static Briefs...Non-Woven Anti Static Briefs,Anti-Radiation Enhance Immunity Yeast Beta Glucan Powder]

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.disc aluminum 1050 1100 1060 3003.[Ceramic Belt Conveyor Pulley]

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.Stainless Steel Socket Welded Flange. 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.[Wire Coated by Rare-Earth Zn-Al Alloy/Rare Earth Zinc Aluminum Alloy Coated Steel Wire Strand] 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,Small Canned Peach Process Plant. 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[Non Woven Pillow 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 (Mini CO2 CNC Laser Cutting and Engraving Machine for Wood Acrylic MDF Paper).High Temperature Resistant Fiberglass Needle-Punched Felts, waste residue is inert and sterile, i.e., environment friendly,Performance Hand Tool Cr-V Steel Shaft PP+TPR Handle Screwdriver(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.[Paper Hangtag Hang Tag Display Card for Garment]
