Phytoextraction

Phytoextraction is an environmentally friendly technique where certain plants are used to remove harmful metals and toxins from contaminated soil. These plants absorb the pollutants through their roots and store them in their stems and leaves. After several growth cycles, the plants are harvested and safely disposed of or processed to recover the contaminants. This method helps clean polluted areas without the need for excavation or chemical treatments, making it a sustainable approach to soil remediation. It is especially useful for cleaning up heavy metals like lead, cadmium, or arsenic from mine sites and industrial areas.
