Jan De Nul Group has just presented a video of the remediation works in Oskarshamn harbor basin in Sweden.
In the past, a copper production site and battery factory discharged their contaminated waste water into the sea, resulting in the whole harbor basin becoming contaminated with heavy metals, PCBs and dioxins.
As shipping continues to sail into and out of the port, the polluted sediments were regularly dispersed over the Baltic Sea.
Envisan has been entrusted with the remediation work to help clean up the port of Oskarshamn sediments, in what is currently the biggest environmental project ever executed in Sweden.
