Product Description: Nu G Medical Waste System Technology (Pyrolysis / Thermal Decomposition) The NU G System uses pyrolysis thermal decomposition to treat infectious wastes typically generated in hospitals. With its compact size and integrated design, it can be installed indoors and is simple to operate. Unrivalled by competition, this unit can be installed in hospitals and similar healthcare facilities to conduct real time disposal and treatment of infectious wastes at the point of origin. The system disposes of, and treats wastes by converting them into gas using an electrical Thermal decomposition system. Inexpensive to install and simple operation of the system provides both a high level of quality assurance and commercial advantage over other options for the safe disposal of Regulated Medical Waste (RMW). Technology: The system uses a method known as "Pyrolysis"; to breakdown the molecular structure of waste materials by elevating its temperature in the absence of oxygen. "Thermal decomposition", or thermolysis, is a chemical decomposition caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition. Thermal decomposition in the Nu G Medical Waste system technology uses electricity. The equipment is designed to destroy pathological wastes from surgery and autopsy (body parts, human and animal tissues, cultures, placentas, blood products). In addition, it will destroy contaminated bandages, dressings, cotton, gauze, gowns, bedding sheets, gloves, masks, sponges and sharps. The stainless steel bin holds up to 40 kgs. or 88 lbs. of waste, and on completion of each cycle, only 2% (or less) of ash remains in the bottom of the bin. The ash is disposed safely into the general waste stream as it is no longer toxic and totally safe. The Nu G mixes the hazardous gases (such as dioxin) at complete combustion ratios, which result in achieving a perfect combustion and pathogen killing treatment in the first and second combustion chambers, thus eliminating hazardous gases.
Characteristics: Simple operation, portable design, and no additional treatment of waste required. Reduces administrative and reporting work related to waste disposal and treatment. Thermal decomposition systems uses electricity creating less noise and is environmental friendly. Designed for low pressure resistance, thus the abrasion and corrosion of insulating materials are minimized. Stainless steel construction is used in thermal decomposition and heating areas and provides superior durability. Installs indoors in a small space. Minimizes the residue ratio after treatment (Residue below 2%). Operational Benefits: Extremely low cost for maintenance and treatment. Saves operating and labor expenses when compared to conventional waste hauling contracts. Simple operation, ease of use, portable design and no additional treatment required. Eliminates labor costs for record keeping, packaging, and manifesting of untreated waste for shipment offsite. Needs only electricity and water to operate. Treated waste can be placed in ordinary trash receptacles for landfill disposal. The liability of the infectious waste generator is reduced with the direct responsibility for chain ofcustody being handled on site. Environmental Benefits: Zero dioxins, hazardous gases or odors. Reduces waste by up to 98%. Low water and electrical consumption. Converts bio hazardous waste to benign trash. Elimination of transportation for offsite treatment yields reduced carbon footprint. Infection Control Benefits: Infectious waste streams can be treated immediately, and not stored in your facility while awaiting pickup by your waste hauler. Minimizes the number of personnel required to handle infectious waste.
What Medical Waste can be Processed? Disposable gowns, surgical operation gowns, surgical drapes, surgical gloves Absorbent cotton (bandages, gauze, etc.) Tissue substances (extracted from the human body or animals) Dangerous wastes (syringe needles, surgical knives, etc.) Synthetic plastics (disposable syringes, blood & solution, bags, etc.) Lab wastes (samples, cultured bacteria, etc.) Disposable diapers (both infants and adults) Other wastes (oils, acids, etc.) Simple Installation: 1. Locate a suitable place for the NU G installation and lock the wheels. 2. Connect the 3 phase 220 volts power. 3. Connect a water line for the cooling water (hoses for water supply and distribution are separately connected). Operation: 1. Press the NU G lid button (UP) on the NU G touch screen and when the button fully rises, push forward and open it sideways. 2. Deposit RED BAG waste into bucket. The NU G can be fully filled with the materials to be processed. Position a bucket with Red Bag waste into the thermal decomposition furnace and close. 3. To close the lid, push the lid all the way until it stops, and press the NU G lid button (DOWN) until the lid closes completely. 4. Press the START button on the touch screen. 5. When the system starts the red light is on, the temperature will rise up to 900 C or 1652oF to liquefy and evaporate the contents in the first chamber. 6. The vaporized material from the first chamber is automatically transferred to the second combustion chamber and is treated again under 1200 C or 2192oF.
7. The treated gas (vapor) has no color and is clean; contains no harmful pollutants and the gas (vapor) is finally passed through the refrigeration chamber. 8. When the process is completed, the red light is turned off and the blue light is turned on. 9. All machines are automatically operated and Thermal decomposed gases are combusted in the first and second combustion furnaces according to programmed temperature and time. 10. Combusted gases undergo a process of temperature reduction and neutralization, thus removing smells and lowering temperature below the level prescribed by any regulations. 11. To cool the heat generated in the process, cooling water comes in and goes out by the automatic cooling system. No water touches the medical waste or the interior of the furnace. 12. Press the Nu G lid button (UP) once touch screen notifies that cooling process is completed. Push lid forward and open is sideways. Bucket with ash contents is removed by pulling bucket out by handle. Bucket can be cleaned by either commercial vacuum or discarded in waste can. Operation Cost: Operation cost below is based on 80 kg (176 lbs.) or two treatment cycles per day (200 beds) Number of treatment cycles per day Total Cost per Day 2 x 88 lbs. = 176 lbs. 176 lbs. => 20kw/h x 2 x 2 times = 176 kw/h 176 kw/h x U$ (1kw/h)
Specifications: Energy consumption. 3 phase 220V, 15kw MAX Power Output.. 20kwH Capacity.40 kgs. (88 lbs.) Water Consumption. 50 Liters (recycled) 13 Gallons Gas combustion period. 1.5 hour Total Weight. 900kg (1,984 lbs.) Overall length 1930mm (76 inches) Overall height 1130mm (44.5 inches) Overall depth....1150mm (45.5 inches) Independent Testing: Waste has been evaluated for dioxin and furan stack emissions. Test runs using PET and HDPE containers found dioxin and furan levels below the recognized Australian emission limit of 0.1 ng/nm3. The plastic material had been completely combusted leaving behind the residue of the contents. These results relate only to the materials tested but give some indication of performance. Emissions from other types of materials would have to be examined on a case by case basis.
