Allseas' river plastics removal

Together on a mission to clean our rivers and oceans

About 150 million tonnes of plastic pollution ended up in our waters in 2016. A recent study estimates that by 2040, plastic pollution will reach 600 million tonnes. Plastic causes a serious threat to the environment. Most of it enters the seas through rivers and ends up in our food chain. Working every day at sea, we witness first-hand the devastating impact plastic pollution is having on the world’s oceans and marine life. Plastic pollution is a global problem, and we are committed to the effort to clean our oceans by developing systems to collect waste in rivers and waterways before it flows out to sea.

Development and installation of plastic collection systems

Two plastic waste collection systems are already installed: Patje Plastic in the Port of Antwerp, Belgium, and Catchy in the Nieuwe Maas river in Rotterdam, the Netherlands. These system are installed at so called “hotspots” and use wind and currents to collect plastic. Our systems are capable of capturing micro- and macro plastics at the water surface and in the upper part of the water column. We are currently working on a third system, called Catchy 2.

Join our mission!

We are collaborating with national and international companies and authorities to rid our seas and oceans of plastic pollution. We are looking for partners to join our mission and develop tailor-made solutions in waterways all over the world. Curious about the possibilities? Send us an e-mail
