Cleaning up the Great Pacific Garbage Patch using conventional methods - vessels and nets - would take thousands of years and tens of billions of dollars to complete. Our passive systems are estimated to remove half the Great Pacific Garbage Patch in 5 years, at a fraction of the cost. Our first cleanup system is set to be deployed mid-2018. This is how it works:
Floating for years in the garbage patch
The system's floater will be a continuous hard-walled pipe made from high density polyethylene (HDPE), an extremely durable and recyclable material.
Together with the screen, its purpose is to catch and concentrate plastic, while also providing buoyancy to the whole system. The pipe is flexible enough to follow the waves and rigid enough to maintain its open U-shape. The floater will be around 1-2 km in length.
The speed the plastic arrives at our moving systems is substantially lower than at a fixed structure, having a positive impact on our systems' capture efficiency. The downforce on the plastic, created by water that needs to move underneath the solid screen, will be smaller. The lower the downforce, the greater the chance particles do not get pulled under the screen.
The forces our moving system has to withstand are significantly reduced compared to that of a fixed structure, where by definition it needs to absorb all forces from the current and the wind added together. The forces on a drifting system become substantially less in comparison, regardless the weather conditions.
Our floating systems are designed to capture small plastic down to 1 cm, up to massive discarded fishing nets (ghost nets) of tens of meters in size.
Models show a full-scale cleanup system roll-out could clean up 50% of the Great Pacific Garbage Patch in 5 years.
By removing the plastic while most of it is still large, we prevent it from breaking down into dangerous microplastics.
Combining the cleanup with source reduction on land paves the road towards a plastic free ocean in 2050.
As what we aim to build has never been built before, a crucial part of our engineering process is to constantly question our design and test our assumptions wherever possible. On top of having a team of creative thinkers as well as a network of external advisors, we often receive useful input from outside sources. If you are an engineer, a researcher, a student or simply an innovative mind, your ideas could help clean the ocean.Share your input
Road TO EXECUTION
Over the past 3 years, we moved from feasibility research, to reconnaissance missions, to extensive scale model- and prototype testing. We expect our first operational cleanup system to be deployed in the Great Pacific Garbage Patch by mid-2018.
Our idea has developed and improved substantially since the first conceptual design and the feasibility study. Since there is no previous technology like ours, we believe the best way to move forward is to test fast and often to look for the things that do not yet work as planned.
By scaling up, researching and working together with world-renowned offshore companies (such as Boskalis, SBM Offshore and Heerema) and institutes (including IMARES, Deltares and MARIN), we believe initiating the cleanup by mid-2018 is achievable.
FUND YOUR OWN CLEANUP SYSTEM
After successfully funding the first ocean trials, we now welcome companies and individuals to sponsor their own cleanup system as part of the large-scale roll-out of the cleanup, scheduled to start in late 2018. If you would like more information on how to be part of the largest cleanup in history, please contact us through contact us, and detail your interest.
