In the article, “Boy Genius Boyan Slat’s Giant Ocean Cleanup Machine Is Real”, Schiller (2017) has reported how Boyan Slat’s improved “Ocean Cleanup” system will effectively collect half of all polymer waste in the “Pacific Garbage Patch” within the next half a decade.
Schiller mentions that Slat’s design was upgraded to use large booms that utilise floating anchors. As the anchors need not be fixed to the seabed, the design will be more cost and time effective to collect a larger amount of polymer waste within half a decade.
Slat’s design enables the booms to drift with the ocean currents and collect polymer waste “towards the center the system”. Slat assures that the system will function despite component failure.
In 2018, Slat aims to collect “tens of thousands of tons” of waste while removing waste from the system periodically. Slat claims he has assessed how the system operations affect the ecosystem. Slat aims to recycle polymer waste collected into recycled products.
Although Slat’s idea to clean up the oceans works by theory, it shows a lack of feasibility in practice.
OCP has shown its first failure just four months after launching their first mission. In an article reported by Rainy (2019), the system faced fracture failure as a result of surrounding ocean currents and winds. Operations to repair the system required transport to bring it back to shore, where it can be inspected and repairs can be executed by mechanics and engineers. As a result, more funds were incurred to repair the damage. The fracture has proved that the system had not taken into account of unpredictable natural conditions present in the ocean.
OCP has also shown that their system is currently being constrained with too many problems. In a promotional video for OCP (CNET, 2018), OCP’s COO Lonneke Holierhoek mentioned that the collection time for polymers is very sensitive as polymers will deteriorate into smaller fragments, making it more difficult to be collected. This implies that the system has a limited time window to collect waste. In an article written by Boffey (2019), Slat aims to expand his device such that it can retain polymers for at least a year. The idea for expansion seems to be improbable given that his initial idea was flawed. Instead, OCP should focus on managing and solving their current issues, before tackling new challenges.
Despite not compromising marine life while operating the system, OCP has failed to take account of all marine lifeforms. Citing from an article written by Guarino (2019), OCP assured the public that marine wildlife will not be trapped in the waste system, as these animals can swim to avoid the waste. However, according to Miriam Goldstein, director of ocean policy at the centre for American progress, she has brought up a point at which animals such as “jellyfish and snails” float on the epipelagic zone, meaning it would not be possible for these animals to evade the waste collection system. This would suggest that the OCP system would be a danger to animals that fall within the same group.
Although there are many flaws in the feasibility of the idea, it is a noble effort to clean up the oceans but more improvement and research need to be done before it can change the world.
