Soils and Sludges

Environmental remediation initiatives often employ lime in a multitude of different applications. Under managed and controlled conditions, lime can be used in the effective treatment of industrial sludges, sewage biosolids, petroleum wastes and acidic drainage from active or abandoned mine sites.  

Adding lime and controlling pH will lock up soluble metals and convert those metals to a more chemically stable form that is less likely to leach. In addition, when added to soils and sludges, lime can be a very effective way to solidify and dewater materials and manage pathogens of various types.  In recent times, lime is being trialed as an aid to improve soil mechanical properties for oil and diesel contaminated soils.
