Lime in Environmental Remediation | GraymontTraduire cette page

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.
