Temporary floating boom for test case of City of Hasselt

Temporary floating boom for test case of City of Hasselt


A temporary floating boom has been installed on the river Demer for test case of the City of Hasselt in Belgium.

Drilling waste in the watercourses is almost invisible and continues to flow without being noticed, and eventually enters the sea.

Mid-2019, the City of Hasselt, together with VMM and our Belgian partner AQWatt, decided to install a temporary floating debris boom by Bolina on the river Demer in Kuringen, Belgium. Six Modular Debris Booms MDB600 with a standard length of 3m were placed at an angle of 45° just in front of the mill arm of the Dorpsmolen in Kuringen.

This MDB600 floating boom of 18m long was left in the water for only 4 weeks, after which an analysis was made of the collected floating debris. Especially the 20cm thick pulp of mixed waste in the form of twigs, microplastics, polystyrene balls and the likes could not possibly be removed manually. However, the bulky waste was sorted and transported to the container park. A total of 45kg of bulky waste was recovered, including glass, plastic bottles and caps, insulation material, waste wood, etc. The waste was then transported to the container park.

Given the full breeding time, nature was not distant, because on the floating debris a bird’s nest had already been made.
