Year Founded:


Founded by Joost Desmet and Bart & Peter Sobry. Initially, DESOTEC activated carbon designed and built different types of installations for water treatment and sludge processing.


DESOTEC activated carbon develops OXYCON®, a hybrid technology whereby the activated carbon filters are aerated. Within this context the company is nominated for the Filtration and Separation Product Achievement Award.


DESOTEC activated carbon starts with the construction of its own environmentally friendly reactivation furnace to recycle spent activated carbon by thermal reactivation for reuse. This reactivation kiln, specialised off gas treatment and continuous exhaust gas monitoring are unique in Europe.


DESOTEC activated carbon constructs a new plant with over 5,000m² of storage space and a special zone for the handling of activated carbon and a completely new office building.DESOTEC activated carbon establishes DESOTEC POLSKA with production facilities and offices in Gdynia (near Gdansk).


DESOTEC activated carbon expands the reactivation capacity with a 2nd reactivation furnace.But this is not all… Further investments are done in the expansion of the fleet of mobile filters, also for the treatment of biogas, and in a special designed truck for the exchange of activated carbon in fixed filters, discharging and loading with the same truck.


AAC Capital Partners, a leading Northern European mid-market buy-out firm, acquired a majority stake in DESOTEC activated carbon whilst the company’s founders retain a significant minority interest.


DESOTEC POLSKA opens a new service centre in Gdansk with a new warehouse, workshop and modern sales offices.


DESOTEC activated carbon develops and patents the world’s largest mobile air treatment filter system, the AIRCON® V-XL. The system consists of a fixed part, the AIRCONNECT®, on top of which the AIRCON® V-XL is positioned. This fixed part is connected directly to the gas to be treated which makes the need of flexible connections superfluous. The AIRCONNECT® – AIRCON® V-XL has a revolutionary design which results in the world’s first real click-and-start activated carbon filtration system for gas flow rates up to 55,000m3/h per unit.


DESOTEC IBERICA. The new branch is located in Tarragona not far from the harbour with sales offices, 1100m2 warehouse and 1200m2 outside storage.


CEO Mario Hertegonne develops and implements with his management team a Pan-European strategy to roll-out DESOTEC’s leadership position in purification solutions with mobile activated carbon filters for 5 markets segments: Air Emission, Biogas, Chemicals, Remediation and Waste Water.


DESOTEC inaugurates its second distribution centre : new warehouse facility of 4500 m² under roof and 10 extra fiilling stations for big filters. Desotec inaugurates as well its third reactivation furnace in Roeselare, enhancing its leading capabilities to reactivate industrial spent activated carbon.


DESOTEC doubles its capacity at its mobile filter technical department in Izegem in order to accelerate its growth in mobile filters. DESOTEC establishes Desotec Italia to support its growth on a Pan-European scale.


The Swedish investment fund EQT buys Desotec from the previous investor AAC and its founders. The current management led by CEO Mario Hertegonne is also investing in the acquisition structure. EQT will support Desotec in further growth and development through international expansion and the investment in reactivation capacity and mobile filter fleet.
