Coal Combustion Residuals Containment

Providing high performance in the most demanding applications

Coal combustion residuals (CCR) are created during the power generation process and can include fly ash, bottom ash, boilerslag, and flue gas desulfurization (FGD) waste. CCRs contain trace concentrations of heavy metals and therefore cannot be dumped or stored where rainwater can leach the metals. Liner systems are typically used to contain the coal combustion by-products and protect them from leaching into the environment. CETCO has engineered our Geosynthetic Clay Liners to meet the harsh conditions encountered in CCR disposal applications.

    DUCK CREEK POWER PLANT
    Central Illnios
    The increased use of coal to generate electricity has brought with it an increased amount of coal combustion by-products (CCBs). Metal ions released from these CCBs can be harmful to the environment and therefore need to be contained.

    TVA KINGSTON
    Harriman, Tennessee
    As part of its emissions control at the Kingston Fossil Plant, flue gas desulfurization is performed, which creates as a by-product a synthetic version of the mineral gypsum and must be stored in a gypsum pond or taken to a landfill.
