ABSTRACT:
A composition particularly useful in solidifying liquid wastes for disposal in landfills, including, for example, liquid industrial wastes. The preferred embodiment of the present invention contemplates a composition primarily composed of bauxite tailings that remain after alumina extraction, also known as "red mud". The tailings are dewatered, dried to a low moisture content, sized to an optimal particulate size, and then applied to the liquid waste. The addition of a small amount of pozzolanic material can improve the handling and solidification characteristics of the composition under certain situations, and is provided in an alternative composition. The present absorption composition is an improvement over existing solidification agents, in that it can absorb liquid hydrocarbon wastes without the water normally required with prior art pozzolanic agents such as fly ash or Portland cement, works equally well with water-based wastes, is less dusty, and readily absorbs and contains transient odors associated with wastes absorbed therein.
