Environmental-remediation initiatives often employ a multitude of lime applications.
Lime can be used in the effective treatment of industrial sludge, sewage biosolids, petroleum wastes and acidic drainage from active or abandoned mine sites. Lime is often used to lockup heavy metals converting them to more stable forms that are less likely to leach, solidify and dewater sludges and neutralise some hazardous wastes. Furthermore, lime is being trialled as an aid to improve soil mechanical properties for oil and diesel contaminated soils.
