We’re wriggling with excitement to let you know that our pilot, in which we tested new nature-based solutions for the dewatering of soft sediment, is complete! Three months ago we started the dredged sediment biologically enhanced ripening experiment on our Delft campus.
In Europe alone we produce 200 million cubic meters of dredged soft sediment per year. It takes a lot of time and resources to dewater and turn it into, for example, soil. Endorsed by the results of our ongoing dredged sediment ripening pilot, we believe worms and plants can be part of impactful nature-based solutions to dewater soft sediment.
Check out our expert Miguel Angel de Lucas, on the experiment’s results. You can clearly see the difference between the various sections (in this video in particular between worms and no treatment, in previous videos amongst all treatments). To reassure you in advance, Miguel managed to climb out of the soft sediment. 😉
“We understand the physical processes involved in the biologically enhanced dewatering of fine sediments and can predict its behavior to a certain extent, but it does not stop to amaze seeing what just a couple of dozen mgs of worms per L of sediment can do to its dewatering speed and bearing capacity. Nature can be a powerful engineering tool, and we are only starting to unveil it”
