BIOTERRA was founded in 1996, in parallel with the activation of the Flemish Soil Directive (Vlarebo), and is specialised in the decontamination of polluted soils and the treatment of mineral waste streams to secondary materials. Since 2007 BIOTERRA is a 100% member of Group De Cloedt, which constitutes of the following divisions:
• Granulates: dredging and processing of primary materials (marine granulats) with also dry quarries in Belgium, Norway and Denmark;
• Dredging: environmental dredging works and treatment of the dredged sludges;
• Environment: civil works on polluted sites, treatment of contaminated soils ans mineral waste (such as also dredging sludge);
• Logistics: own fleet of vessels (based in Breskens, Holland).
BIOTERRA has a network of sites, all located adjacent to important waterways, whereby these sites purpose the collection of soils and waste, to group those materials which must undergo the same treatment/valorisation to at least being valorised or transported to the main treatment center in Genk. The site of Genk is equipped with a state-of-art wet separation installation to treat heavily polluted soils and well charged mineral waste streams. The current sites are located at Genk (primary site), Meerhout, Puurs, Floreffe, Nanterre (France) and Copenhagen (Denmark) and cover approx. 25ha in total. BIOTERRA handles each year approximately 1 million ton of soil and waste and has made a revenue of € 22 million in 2015.
