Project: GROYNE 42
The yet unsolved problem
Groyne 42 is a dump for poisonous sprays and other toxic waste constructed at Breakwater 42 at Harboøre Tange in Denmark facing the North Sea.
The area was used for depositing toxic waste in the years 1957 to 1962. The pollution at Groyne 42 at Harboøre Tange in Denmark has been an unsolved problem for decades with several attempts to treat the waste and protect the surrounding area.
Ground breaking MOPS technology and expected results by the end of 2019
Fortum is now ready to implement the first full-scale test of the technology that can clean up the sand of mercury and pesticides, among others. Already last autumn, MOPS technology (Multi-purpose On-site Phase Separator) showed promising results in laboratory tests and small-scale tests. If the results of the sustainable cleaning process keep what the tests have promised so far, the flexible MOPS technology will be able to detoxify and recover valuable raw materials from soil, fly ash and waste water sludge at many places all over the world.
The pilot test of the locally situated plant will take place during the summer of 2019. Fortum expects that in October 2019 results could be seen with cleaned sand that could be recycled. In addition, there is a minor quantity of concentrated contaminated material to be removed and incinerated at Fortum’s plant in Nyborg.
“In our previous tests, we succeeded to remove the contents of pesticides completely and reduce the
mercury contents to a level where it cannot be measured. This fact confirms the potential of the
technology and strengthens our expectations to the test in full-scale”, Jens Peter Rasmussen, Business Responsible with Fortum Waste Solutions A/S
Materials from the site to be recycled and re-used
Fortum expects that only five percent of the total quantity of sand will be sent to high temperature plant in Nyborg for final treatment. Thus, 95 percent of the sand from the groyne is so clean after the local treatment that it can be used as filling material for road construction or other construction purposes within the frames of the soil quality criteria issued by the Environmental Protection Agency in Denmark.
