Optimizingthe placement of cleanup systems for marine plastic debris : Amulti-objective approach

Marine plastic pollution is a pervasive problem and is estimated to only increase over the coming years. The realization of this has made several actors take action, of which one is the Danish Hydraulic Institute. Their simulation software MIKE allows for particle tracking in water environments, mak...
