  • Incineration

    Introduction: High temperatures, 870 to 1,200 °C (1,400 to 2,200 °F), are used to volatilize and combust (in the presence of oxygen) halogenated and other refractory organics in hazardous wastes. Often auxiliary fuels are employed to initiate and sustain combustion. The destruction and removal efficiency (DRE) for properly operated incinerators exceeds the 99.99% requirement for hazardous waste ...

  • Artificial carbonation for controlling the mobility of critical elements in bottom ash

    In municipal solid waste incineration (MSWI), bottom ash, generated at a stoker grate type incinerator, the critical elements were identified in terms of EU regulation. The stabilizing effect of moderate carbonation (pH 8.28 ± 0.03) on critical contaminants was studied through availability and diffusion leaching protocols. Data from the performed tests were evaluated with the goal of reusing MSWI ...

  • The Influence of PVC on the Quantity and Hazardousness of Flue Gas Cleaning Residues from Incineration

    The study estimates the influence of PVC on the quantity and hazardousness of flue gas residues from incineration. The analysis has been carried out on both theoretical and practical terms. A distinction between dry, semi-dry and wet gas treatment systems has been made. The influence of PVC has been assessed on the combustion steps and therefore on the distribution of chlorine and other ...

  • Preparation and characterization of sorbents prepared from ash (waste material) for sulfur dioxide (SO2) removal

    Sorbents synthesized from various types of ash (coal fly ash, coal bottom ash, oil palm ash, and incinerator ash) for flue gas desulfurization were investigated. The sorbents were prepared by mixing the ashes with calcium oxide and calcium sulfate using the water hydration method. The effects of various sorbent preparation variables, such as the hydration period, the ratio of calcium oxide to ...

  • Volatility of heavy metals during incineration of tannery sludge in the presence of chlorides and phosphoric acid

    Knowledge of the behaviour of heavy metals in the combustion process is a most important factor in selecting disposal alternatives for waste materials. Accordingly, in this work, the vaporization behaviour of highly concentrated heavy metals (Pb, Zn, Cu and Cr) in tannery sludge were investigated experimentally. The sludge was spiked with various chlorine compounds (i.e. PVC, FeCl3, CaCl2 and ...

  • Multiple stage scrubbing and adsorption system for Incinerator exhaust at an industrial waste processing plant

    Challenge Monroe Environmental was called upon to purify a 20,000 CFM exhaust stream that was being discharged from an industrial waste incinerator at 2000° F. The pollutants that needed to be removed were: Fine Ash Particulate HCL Gas Mercury Dioxins The combination of soluble and solid pollutants, coupled with the ...

  • FAQ About Plasma Arc Gasfication Process from Plasma Waste Recycling, Inc (PWR)

    What is Municipal Solid Waste? Municipal solid waste (MSW)—more commonly known as trash or garbage—consists of everyday items such as product packaging, grass clippings, furniture, clothing, bottles, food scraps, newspapers, appliances, paint and batteries. It does not contain industrial, hazardous, or construction waste. Since 1980, the total annual volume of MSW generated in the U.S. has ...


  • The use of thermal plasma technology for treating air pollution control residues

    Energy from waste (EFW) is an exciting industry to be in right now in the UK. As pointed out by Euston Ling and Dr. Adam Read's article "The Shifting Landscape for Renewable Energy in the UK" {Waste Advantage Magazine, June 2011), the EFW capacity in the UK is set to grow strongly in the next 10 years, with some commentators predicting a three-fold increase in EFW capacity from the current 4 ...

  • Soil physico-chemical changes following application of municipal solid waste leachates to grasslands

    AbstractConcerns about the use of residues from municipal solid waste incinerators (MSWI) in construction materials usually focus on the potential for heavy metals and organic chemicals to leach into drainage waters under the influence of rain. We hypothesised that high level of salts in the MSWI leachates may cause more of a problem, particularly on soil physico-chemical properties. Both bottom ...


  • Controlling Stack Emissions in the Wood Products Industry

    Electrostatic precipitation has been a reliable technology since the early 1900's. Originally developed to abate serious smoke nuisances, the manufacturers of zinc, copper, and lead quickly found electric gas cleaning a cost efficient way to recover valuable product carried out of the stacks from furnace operations. Today electrostatic precipitators are found mainly on large power plants, cement ...


  • Thermal recycling of spent grains – residue becomes resources

    Introduction – the History of Beer The origin of beer was a happy coincidence: In the fourth millennium BC, the Sumarians discovered the fermentation process. The country of the Sumarians, called Mesopotamia, was located between the Euphrates and the Tigris. The Sumarians wanted to help an ill person swallow some bread, so and they soaked a piece in water. They simply forgot the bread in ...
