Denmark to build nine artificial islands off the coast of Copenhagen

The project involves creating nine artificial islands 10 kilometers off the coast of Copenhagen by 2040. Construction is set to begin in 2022, using soil from construction projects and Swedish surplus soil. The islands will serve various purposes, including housing a wastewater conversion plant and windmills for energy storage, while others will be used for recreation.
