Highly toxic heavy metals, organic and chlorinated compounds... These are just some of the substances that can remain in the soil as residues from industrial activity and become responsible for environmental pollution and the poisoning of plants, animals and, potentially, of man.
To reclaim a site using traditional methods, it is necessary to dig up the contaminated soil and dump it somewhere else, or to take it to a plant where a series of chemical, physical, thermal or biological treatments will extract the pollutants or degrade them into less dangerous compounds.
However, by using these methods, the technologies that are used to clean the soil actually add to the existing pollution. The dust that is displaced by removing the contaminated soil and transporting it, by truck or other means, to the reclamation plant contributes to dispersing polluting substances into the environment, together with the fine dust.
However, there is an alternative on the horizon: At Eni, we are developing low environmental impact reclamation processes that can reduce - if not eliminate - the pollutants present in the soil to levels that are no longer dangerous to human health. if not altogether eliminate them.
