  2. COMPOSITION OF MEDICAL WASTE

  3. AVERAGED ULTIMATE ANALYSIS OF MEDICAL WASTE

  4. ADVANTAGES OF PLASMA METHODS FOR WASTE PROCESSING • Complete decomposition of the waste with the formation of basic compounds that considerably simplifies the cleaning of contaminants; • Possible co-processing of different types of waste without pre-sorting; • A significant decrease in the volume of flue gases, and, consequently, the load on the gas cleaning system; • Smaller carryover of dispersed particles ; • High performance with small dimensions of equipment; • Ability to create a desired gaseous atmosphere; • Ability to produce the final product in a stable form; • Possibility of operative adjustment the process by changing the flow rate of oxidant (air) and power of plasma torches.

  5. THERMODYNAMIC MODELLING For computation of the solid fuels gasification thermodynamic code TERRA was used. The calculations were performed over a range of temperatures from 400 to 4000 K and pressure 0.1 MPa. Composition of bone meal for processing in plasma furnace: 1. The moisture content ≤9%; 2. The fat content ≤ 10 %; 3. Ash ≤ 61 %; 4. The protein ≥19 %; 5. Metallic impurities ≤ 200 mg/tone Bonetissue (boneofadultanimal) hasthefollowingchemicalcomposition (wt.%): Ca10(PO4)6(ОH)2 – 70, C – 14, O – 9, N – 4, H – 2, S – 1.

  15. PARAMETERS OF THE PLASMA BOX FURNACE • Burning device - DC plasma torch, output power of 15 to 35 kW. • Plasma forming gas – air, flow 1,0-2,0 g/s. • Geometric dimensions of the box furnace: height – 220 mm, side - 220 mm, lining - 40 mm. • Amount of processed material - animal bone and bone meal: 10,0-14,0 kg / h • Modes of operation: warming up - 5 minutes, burning of organic matter - 3 min, melting of inorganic - 7 min. The total work cycle (including cooling and loading of new portion) - 30 min.

  16. GAS COMPOSITION AFTER PLASMA PROCESSING OF BIOMEDICAL WASTE

  17. Conclusions In the plasma box furnace the process of recycling of organic matter takes place. Waste under the influence of temperature is completely broken up to form of simple chemical compounds. The relative contents of processed products depends on the humidity and temperature of the process. Plasma-recycling technology is a universal.It can be used for recycling of any waste, regardless of their qualitative and quantitative composition. Developed the technology and equipment to implement the process of thermal processing of solid and packaged biomedical waste is tested on real materials - animal bones.
