  • 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 ...

  • Separation of metals and phosphorus from incinerated sewage sludge ash

    Microbial acidification of incinerated sewage sludge ash and dissolution of metals from the acidified ash were investigated using a semi-batch reactor at different solid retention times (SRTs). The average pH values ranged from 0.91 to 1.2 at SRTs longer than 10 days, whereas the reduction of SRT to 4 days resulted in an increase in the pH value to about 2. The dissolution efficiencies of Al, ...

  • Like a phoenix from the ashes

    Thanks to growing environmental awareness, waste is increasingly being separated and recycled. However, residual waste always remains that can't easily be recycled. This ends up in waste incineration plants (referred to as KVAs in Swiss German) for disposal and reclaiming, such as the KVA Linthgebiet in Niederurnen in the Swiss canton of Glarus. Due to the strict environmental specifications ...

  • Pollutant emissions from modern incinerators

    Emissions of dioxins are mainly from incinerators, domestic and industrial coal combustion, and traffic. However, the major public concern and research effort are associated with the emissions of organic micropollutants from waste incinerators. This paper gives a brief overview of the more recent research and development for the removal of dioxins and heavy metals from flue-gas streams. Special ...

  • Management of sewage sludge and ash containing radioactive materials

    Approximately 50% of the seven to eight million metric tonnes of municipal sewage sludge produced annually in the US is reused. Beneficial uses of sewage sludge include agricultural land application, land reclamation, forestry, and various commercial applications. Excessive levels of contaminants, however, can limit the potential usefulness of land-applied sewage sludge. A recently completed ...

  • Characterisation of Incinerator Residues for Their Possible Re-Use

    MSW incineration produces a high quantity of residues (slags, fly ashes, sludges). Recycling suitability of residues is therefore an important issue requiring as a first step their physical and chemical characterisation (mass, granulometry distribution, merceology) and determination of their hazardousness (i.e. pollutant contents of heavy metals and chlorinated organic compounds). ...


  • Supercritical water oxidation presented as alternative to incineration – An update

    Environmentally benign waste disposal is becoming a more and more acute problem. A process now being commercialised, supercritical water oxidation is demonstrating extremely efficient organic waste destruction (99.99%) plus excellent environmental characteristics (none of the emissions associated with incineration). The process is especially suitable for the treatment of wastewater and sludges ...

  • UK Abattoir – Rotary incinerator - Case Study

    Designed to process animal remains 24 hours/day, 7 days/week, with the minimum of operator attendance. To optimise the plant’s performance and to enable waste to be processed and stored, irrespective of the status of the combustion plant, the waste is crushed into 50mm cubes. The material is then conveyed into a buffer hopper, which stores sufficient material to enable the plant to be left ...

  • Technical Note: An effective thermal technology for the detoxification of MSW fly ash

    Increasing public concern regarding potential health problems due to improper waste disposal practices and the introduction of landfill taxes have induced the practice of incineration. Presently, all UK incinerators have to meet very strict emission levels. The municipal solid waste (MSW) fly ash generated has to be managed very carefully as it is enriched with toxic organic micro pollutants and ...

  • 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 ...

  • Study on cement mortar and concrete made with sewage sludge ash

    This study investigated the feasibility of reusing wastewater sludge ash in construction materials to replace partial materials. Wastewater sludge sampled from thermal power plant was burned into sludge ash at 800°C in the laboratory. The sludge incineration ash has low heavy metal including Pb, Cd, Cr and Cu, so it belongs to general enterprise waste. The chemical composition of sludge ...

  • 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 ...

  • Are incineration and landfills the answer to save us from the recycling crisis?

    For plastic recycling, this year hasn’t exactly been one of the best – what is to blame? Oil. Shockingly, it actually costs more to recycle old plastic than it does to make new in many ways. Petroleum prices have fallen so low, as low as 70% below the level in June 2014. This may be great for some – however with it has fallen the cost of Virgin Plastic which is made from ...

  • Recycling Vs. Landfills and Incinerators – Do Benefits of One Outweigh the Other?

    Believing the 2011 survey results of the U.S Environmental Protection Agency (EPA), the American nationals generate more than 240 million tons of waste every year. Often referred to as Municipal Solid Waste, this waste originates from households, schools, hospitals, and business establishments. This trash material often finds its place in the wasteland, where it is either recycled, trapped in a ...
