  • Environment impact from ash disposal of the thermal power plant 'Kosova A'

    Mining activities impact on environment is as old as these activities themselves. It is estimated that thermal power plants in Kosova produce about 1.6 million tons of ash per year, and all ash produced is disposed as waste material. The main problems for environment pollution are the ash dumps containing more than 40 million tons of ash cover about 150 ha of land. The ash dumps sites of the ...

  • How toxic is coal ash? A laboratory toxicity case study

    Under a consent agreement among EPA and proponents both for and against stricter regulation, EPA is to issue a new coal ash disposal rule by the end of 2014. Laboratory toxicity investigations often yield conservative estimates of toxicity since many standard test species are more sensitive than resident species, thus could provide information useful to the rule‐making. However, few laboratory ...

  • Geochemical studies to delineate topsoil contamination around an ash pond of a coal-based thermal power plant in India

    In the present study, an attempt was made to delineate soil contamination around the ash pond of a coal-based thermal power plant. The topsoil in the study area was found to be contaminated to varying degrees from ash disposal. The soil drawn from various profiles was largely contaminated by ash fall out, predominantly in the prevalent wind direction. Pb, Zn, Cu, Ni, Co, Mn, Cr, V and Ba were ...

  • Inorganic contaminants attenuation in acid mine drainage by fly ash and its derivatives: column experiments

    Treatment of AMD with fly ash (FA) is a promising technology but solid residues (SR) generated in the process pose a disposal challenge. This study evaluates the suitability of the SR and SR, FA/ordinary Portland cement (OPC) blends for backfill in mine voids and in–situ treatment of AMD flows. The mitigation of AMD in a mine void was simulated by addition of simulated acid mine drainage ...

  • Application of Ecological Risk Assessment in Managing Residual Fly Ash in TVA's Watts Bar Reservoir, Tennessee

    The Tennessee Valley Authority conducted a Baseline Ecological Risk Assessment (BERA) for the Kingston Fossil Plant ash release site to evaluate potential effects of residual coal ash on biota in Watts Bar Reservoir, Tennessee. The BERA was in response to a release of 4.1 million m3 of coal ash on December 22, 2008. It used multiple lines of evidence to assess risks for 17 different ecological ...

  • 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 ...

  • 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 ...

  • Why is Energy-from-Waste slow to catch on in the U.S.?

    Nithin Coca reports in TriplePundit that Energy-from-Waste (EfW) is growing fast in Europe and parts of Asia. But it’s relatively stagnant here in the United States. In fact, the percentage of waste we burn for energy is actually slightly down in the past five years. What’s holding the U.S. back from this potentially sustainable solution? This stagnation is even more ...
