Tank Service, founded in 1994, focuses on internal tank washing. Tank Service is SQAS-rated and operates two facilities: one at Saint Pol-sur-Mer and the other at Vieux-Thann. In addition to its main activity, the Saint-Pol-sur-Mer site recycles plastic IBCs recovered from local manufacturers. Both sites operate under a prefectoral decree guaranteeing compliance with environmental standards. Tank Service has been a member of the APLICA association since 1994, and issues EFTCO washing certificates to showcase its experience and expertise.
