  • 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). ...


  • A novel approach to remediating contaminated groundwater by reusing industrial co-products

    This paper presents a novel approach to remediating contaminated groundwater by utilising industrial co-products. The materials discussed include paper clay and steel slag, and the primary water contamination considered is heavy metal contamination. Paper clay was determined to have the potential for adsorbing heavy metals, and in compacted form could achieve permeability values within the ...

  • 25 Years of Success – Outokumpu Stainless DC Plasma Smelting Facility

    Design is not just what is looks and feels like. Design is how it works. Between 1982 and 1987, British Steel (Outokumpu today) made extensive investigations into the treatment of steel dust. Their research was far and wide and covered off many various methods of recycling, including alternative to plasma technologies. But, in 1985, they engaged Tetronics International to carry out a ...

  • City of Montgomery announces intent to contract with PWR for world`s first waste-to-energy plant utilizing the PWR process

    Days after the city brought an end to its curbside recycling program, Montgomery Mayor Todd Strange announced it will pursue an ambitious, cutting-edge program to reuse almost all of the city's garbage by converting it into energy or slag and metal. Strange believes the city could save as much as $3 million by letting a Huntsville company gasify its waste, as well as the garbage of other ...
