Here you can find brief information about a few of our completed projects.
A pilot project to freeze dewater oil polluted sludge at the Ragn-Sells recycling and remediation plant in Högbytorp. Via our mobile freeze plant the unique FriGeo freeze technology is applied to reduce sludge volumes and thereby facilitate handling and remediation work. Ragn-Sells is Sweden’s leading recycling and remediation facility with operations in six countries across Europe.
To remove mercury-contaminated sediments in a 2700m2 large sea bay polluted by the process water of a nearby chemical plant. Through the FriGeo method of freeze dredging the contaminated sediments were safely removed from the seabed and transported to a remediation facility for further treatment.
To stabilize oil-polluted sediments in a canal near the lake of Vassaraträsk prior to excavation work. Vassaraträsk is part of Natura 2000 - an ecological network of protected areas in the territory of the European Union.
To freeze dredge the alpine lake of Vassijaure in Swedish Lapland with the purpose of removing oil-polluted sediments. Through freeze dredging it was possible to minimize turbidity and prevent the dispersal of material during removal.
To stabilize the wreck site of a military DC-3 aircraft on the seafloor of the Baltic Sea, at a depth of 125m. After stabilizing the bottom sediments via freeze technology, pieces of the 1952 wreckage were salvaged in a frozen state and transported to a forensic investigation carried out by the Swedish Police and the Swedish Accident Investigation Board (SHK).
To remove contaminated sediments in a tunnel at the underground Muskö Naval Base as part of an environmental impact investigation conducted by The Swedish Defence Research Agency.
