Soil is an essential component of our planet, mainly because it participates in various processes that make life possible in Earth. One of the most important roles is to provide food, due to more than 95% of the world's food production depend on the soil. However, soil contamination is a constant threat, since soils are not considered as a renewable resource; therefore, it is necessary to remedy them. Heavy metals are a frequent contaminant that endangers the natural balance of soil processes and constitutes a threat to human health. In this regard, there are remediation techniques that seek to remove and immobilize them. Some of these techniques are the biological and physicochemical ones, which use plants (phytoremediation), and others use thermal treatments (thermal desorption), respectively.
