Environmental-remediation initiatives employ a multitude of lime applications. Following are a few examples of how lime is being widely used as the reagent of choice when responding to environmental problems.
For instance, lime is a cost-effective reagent for the treatment of animal wastes, particularly as the feed-lot industry consolidates and transitions to large-scale feeding operations that produce significant volumes of waste.
Lime can also be used for effective treatment of sewage biosolids, including municipal wastewater, as well as industrial sludge, petroleum wastes and acidic drainage from active or abandoned mine sites.
As well, lime is employed to treat hazardous wastes. Lime stabilizes most metals by converting them to more chemically stable forms that are less likely to leach. In addition, when added to soil, lime can be a very effective way to solidify material and prevent future discharge of hazardous wastes.
There are many other applications for lime in environmental-remediation projects.
