Process remediation of an ash by-product from a Combined Heat and Power Plant, the process comprising the steps of combing the ash by-product with a liquid mobilisation agent, heating and separating the mobilised ash to form a salt product and de-chlorinated ash, transferring the salt product to an evaporator to form a chloride salt precipitate, combining the de-chlorinated ash with a liquid mobilisation agent and removing heavy metals to form an ash residue substantially free of chemically active contaminants. The step of heating the mobilised ash ideally uses excess or secondary heat from the power plant. The mobilisation is ideally water. The ash residue may be used as a low strength material, a filler or an additive to a blended soil product. |
