Bioventing and SVE

In the context of environmental remediation, Bioventing and Soil Vapor Extraction (SVE) technologies are two effective approaches for the in situ reclamation of contaminated soil.

Bioventing consists in injecting air into the subsoil to stimulate aerobic, auctotonous bacteria to more rapidly decompose organic pollutants such as hydrocarbons, while promoting their natural biodegradation process.

On the other hand, SVE technology works by extracting vapours from the subsoil, creating a vacuum that facilitates the removal of volatile contaminants. The extracted vapours are then treated and broken down using specific systems, such as activated carbon filters or thermal combustors.

The two technologies often operate in a combined mode: vapour extraction introduces fresh air into the soil, enhancing at the same time the action of Bioventing and therefore accelerating remediation.

The Manfredonia Site of National Priority, where we have already carried out remediation interventions on and made available over 94 hectares of the 96 hectares owned, is an example of a site where we are applying Bioventing and Soil Vapor Extraction technologies to complete the reclamation of the area known as Island 16.
