Abstract

Phytoremediation includes utilization of plants to remediate polluted soils. In this chapter, application of Vetiver grass in phytoremediation of heavy metal contaminated soils is discussed. Case studies in Australia, China, and South Africa are presented. The future application may be in the areas of mine site stabilization, landfill rehabilitation, leachate treatment, wastewater treatment, and other land rehabilitation. It is a low-cost remediation method.
