The Public Waste Agency of Flanders (OVAM) is combating historical soil and groundwater pollution in the De Lieve watercourse with the installation of innovative reactive mats. These mats are filled with biochar contributed by our partner company NovoCarbo GmbH. The pollution originates from industrial activities from the 19th century. The water purification is part of the European project RESANAT (“REstverontreiniging SAneren met NATure-based technieken”), a Flemish-Dutch partnership. The environmental company Esana is the implementing company.
These innovative mats are placed after the contaminated sludge layer has been removed. They are designed to filter the pollutants from the groundwater and break them down naturally. In this way, they protect the surface water from contamination until the surrounding land is fully remediated.
