Phytoremediation has become a proven, low-impact technique for the recovery of contaminated soils and waters. At Litoclean, we apply this natural strategy in combination with advanced testing at our Innovation Center (CIL)<\/a> and the expertise gained from European projects such as Phy2Climate<\/a>. <\/p>\n\n

What is Phytoremediation?<\/h2>\n\n

Phytoremediation is a bioremediation technique that uses plants and microorganisms associated with their roots to eliminate, immobilize, or transform contaminants<\/strong> present in soils, water, and sediments. It is an in situ, low-cost solution with minimal environmental disruption. <\/p>\n\n

Types of Phytoremediation and Their Applications<\/h2>\n\n

Each type of phytoremediation is suited to specific contaminants and environmental conditions:<\/p>\n\n

Phytoextraction<\/strong><\/p>\n\n

This involves the absorption of contaminants\u2014mainly metals such as lead, cadmium, or zinc\u2014by plant roots. These elements are transported and accumulated in the aerial biomass. The plants can then be harvested and, in some cases, processed through phytomining<\/strong> to recover valuable elements. <\/p>\n\n

Phytostabilization<\/strong><\/p>\n\n

Through this mechanism, roots immobilize contaminants in the soil or bind them within plant structures, reducing their mobility and bioavailability. This prevents their spread to groundwater or entry into the food chain. <\/p>\n\n

Rhizodegradation<\/strong><\/p>\n\n

In the rhizosphere\u2014the soil zone surrounding the roots\u2014plants exude compounds that stimulate the activity of microorganisms specialized in degrading organic pollutants. This plant-microbe symbiosis is key to eliminating pesticides, hydrocarbons, or solvents. <\/p>\n\n

Phytovolatilization<\/strong><\/p>\n\n

Certain plant species transform specific contaminants into less toxic volatile compounds, which are released into the atmosphere through their leaves. Although this technique requires special caution, it can be useful for elements such as mercury<\/strong> or selenium<\/strong>. <\/p>\n\n

Phytofiltration<\/strong><\/p>\n\n

Particularly effective in contaminated water, where roots act as living filters that adsorb or absorb contaminants in aqueous solutions, including metals, nutrients, or organic compounds.<\/p>\n\n
