Clewat Oy

Clewat Oy • Co-Founder

Instead of good intentions for the future, the Clewat solution is available and operating now. We bring new efficiency into the fight for saving the seas. We develop and manufacture water cleaning vessels that are able to clean up garbage and microplastics from waterways. The technology of our vessel is based on the creation and utilization of water flow. Our product is a catamaran raft which, with the booms in front, collects garbage at the mouth of the vessel, where the water flow is regulated so, that various garbage and impurities end up on the vessel’s conveyor and further sorted into trash. By adjusting the length of the booms, the width of the area to be treated, can be increased even over a kilometer. A cleaning device developed by Clewat is one of the few concrete solutions to the marine plastic waste problem that works. We are able to collect from the water up to half a millimeter-sized particles, and at most our equipment can collect as much as 200 cubic meters of biomass per hour.
