  • Application of leachate pollution indices for assessment of leachate pollution potential of landfills (a case study of an unlined landfill with lime sludge and fly ash)

    Leachates from unlined landfills cause environmental degradation and health hazards due to resultant ground water pollution. Their pollution potential can be measured on a comparative scale using leachate pollution index (LPI). The selection of index involves 18 pollution parameters, their weightages and the sub–index values. The concentrations of pollutants are obtained from toxicity ...

  • Laboratory investigation of hydraulic characteristics of fly ash as a fill material from the aspects of pollutant transport

    Depending on the usage of fly ash, it is necessary to determine its environmental parameters, such as the potential for pollutant transport/leaching after its built-in. This study presents a methodology for determination of transport parameters (filtration coefficient, effective porosity, longitudinal dispersivity, and the mean residence time) from experimental data collected from column ...

  • Legal lookout: EPA responds to coal ash release

    Once again, it took a major catastrophe to wake up industry and regulators to a problem that should have been addressed long ago. Dec. 22, 2008, was a nightmare for federal and state regulators, electrical utilities, and most particularly the residents of Kingston, Tenn. On this day, approximately 5.4 million cubic yards (or 1.1 billion gallons) of coal ash from the Tennessee Valley Authority ...

  • An immobilisation mechanism for lead in fly ash subjected to mechanochemical treatment

    Mechanochemical (MC) processes immobilise heavy metals in fly ash, a desirable outcome because recycled fly ash is commonly used in the synthesis of inorganic materials. We investigate the extent of immobilisation and the mechanism of lead (Pb) leaching during MC treatment of fly ash, using lead oxide (PbO) and lead dichloride (PbCl2) as model compounds. MC treatment of the ...

  • 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 ...

  • EPA targets electric utilities - the agency steps up efforts to manage coal ash damage

    Approximately 5.4 million cubic yards, or 1.1 billion gallons, of coal ash from the Tennessee Valley Authority (TVA) plant near Knoxville, Tenn., in December 2008 flooded some 300 acres of land, damaging property, polluting waterways, and killing fish. TVA will likely spend more than $500 million and perhaps as much as $1 billion dollars on the cleanup, says the U.S. Environmental Protection ...

  • Review of coal as a promising source of lithium

    Coals are a major source of pollution in certain parts of the world due to mining, coal combustion, and disposal of fly ash. The recovery of valuable rare metals from coals or coal–processing byproducts is a promising way to utilise these traditional resources economically, efficiently and in an environmentally friendly way. Lithium, a highly interesting metal, has been found dispersed and even ...

  • Coal-fired power on the way out?

    The past two years have witnessed the emergence of a powerful movement opposing the construction of new coal-fired power plants in the United States. Initially led by environmental groups, both national and local, it has since been joined by prominent national political leaders and many state governors. The principal reason for opposing coal plants is that they are changing the earth’s climate. ...

  • How can we use Biomass as an energy source?

    Any Country which has Agriculture or Forestry waste available has big scope to use biomass as an energy source. We can use Biomass as fuel in its loose form but we can also bind them in solid fuel for more energy consumption. Any biomass like forestry waste, Agriculture waste or any other biomass waste can be recycled into solid biomass fuel/Bio coal/White coal/Briquette. What is ...
