Only through broad, open collaboration can the dredging sector make the desired transition to zero-emission dredging. Rijkswaterstaat and the ZEDHub collaboration initiative are leading the sector in this effort. In September 2026, three research projects will begin to fill knowledge gaps. The results will make subsequent decisions more accurate, realistic, and less risky.

Synthetic geotextiles are often used for temporary construction roads, even though their lifespan is much longer than necessary. That is why the Joosten Group is researching Jogetex HV, a biobased and biodegradable alternative made from wood fibers.
