Who is Boyan Slat
Boyan Slat was born on 27 July 1994 in Delft, the Netherlands. He founded and leads the nonprofit The Ocean Cleanup. [1]
Origins and early support
He began Aerospace Engineering at TU Delft in 2012 and left in 2013 to focus on the organisation. [1]
In his account, the idea began when he encountered rubbish while diving in Greece aged 16. He developed it into a school project and presented an initial proposal at TEDxDelft in 2012. His early concept used ocean currents to concentrate plastic instead of pursuing individual pieces with vessels. [6]
The feasibility study presented in June 2014 brought together work by scientists and engineers. It assessed whether the concept could be developed and provided a basis for later testing. This phase preceded sea trials: investigating possible performance and demonstrating it under real conditions were distinct stages of the project. [21]
The 2014 crowdfunding campaign raised more than$2.15 million from over 38,000 people in 160 countries, according to the organisation’s account. The money supported engineering and oceanographic expeditions. Building a donor community therefore accompanied the formation of the team and the development of prototypes. [7]
Research on marine plastic
Slat co-authored the 2018 Scientific Reports study of plastic accumulation between California and Hawaii. The team combined marine sampling, aerial observations and modelling. It estimated around 79,000 tonnes across 1.6 million square kilometres: debris of different sizes distributed through an area, rather than a continuous solid surface. [8]
Development of ocean cleanup systems
System 001 launched in September 2018. Testing revealed two problems: ineffective plastic retention and a fatigue fracture that detached part of the structure. It returned to Hawaii in January 2019. Subsequent analysis led the team to reconsider relative speed through the water and the design of connection points. [9]
In October 2021, Slat and ocean operations director Henk van Dalen presented System 002’s results. The organisation reported nine extractions and 28,659 kilograms of plastic collected during twelve weeks of testing. This marked a transition from early concept trials towards collection operations and the design of a larger version. [10]
System 03 was deployed in August 2023. It included a floating barrier approximately 2.2 kilometres long, towed slowly by two vessels, with a screen extending about four metres below the surface. Debris gathers in a retention zone before extraction. The equipment operates within a maritime operation involving crews and logistical support. [11]
Interactions with animals are part of design and environmental assessment. System 03 introduced the Marine Animal Safety Hatch: when an animal is spotted in the retention zone, an exit can be opened while access further into the system is blocked. The measure is intended to reduce entrapment during debris collection. [12]
Interceptor and river pollution
Interceptor Original was introduced in October 2019 to act before waste reaches the sea. A barrier guides floating material towards a conveyor belt and containers. The original version uses solar energy for automated extraction, while removing collected material and managing it locally remain parts of the operation. [13]
A 2021 Science Advances study by Meijer and colleagues estimated that more than a thousand rivers accounted for 80% of riverine plastic emissions into the ocean. It used waste, land use, wind, rainfall and river-network data. This work by the scientific team and its collaborators helps identify where potential interventions should be investigated. [14]
Data, modelling and artificial intelligence
In July 2025, The Ocean Cleanup and Amazon Web Services announced collaboration on artificial intelligence, machine learning and cloud computing. The aim is to turn ocean observations into information for locating plastic concentrations and planning extraction more effectively. Teams from both organisations are responsible for the technological work. [15]
In 2026 the organisation described its Smart Steering Strategy to address an operational problem: debris moves and observations can become outdated. The strategy combines locating concentrations with predicting movement so that collection systems can be directed towards them. Research and testing campaigns aim to evaluate that integration before expanding operations. [16]
Cities programme and organisation
The 30 Cities programme, announced in 2025, proposes moving from individual river projects to coordinated interventions in cities across Asia and the Americas. It aims to reduce plastic entering the ocean through rivers by up to a third by 2030. Delivering that target requires agreements, funding and local operational capacity. [17]
Mumbai illustrates that scale of work. The organisation reports initial 2026 permits for two Interceptors and further authorisations after monsoon testing. The project combines municipal cooperation, research with TERI and Plastic Fischer as an implementation partner, adapting the intervention to the city’s conditions and participating organisations. [18]
The leadership structure also changed in 2026. Rene Bastiaan Net became 30 Cities programme director and Henk van Dalen took charge of Science and Technology. These roles connect research, design, deployment and operations while Slat remains chief executive. Development depends on that distribution of responsibilities and on external partners. [19]
International recognition
UN Environment recognised him in 2014 with the Champions of the Earth award in the Inspiration and Action category for his initiative addressing ocean pollution. The award came during the early research and support-building stage, before the successive systems later tested in the Pacific. [20]
Safety management at The Ocean Cleanup
The Ocean Cleanup’s 2024 report states that 63% of its crew attended quality, health, safety and environmental workshops. It also describes the organisation’s review of incident processes, protective equipment, corrective actions and change management. [4]
The organisation also explains that systems are inspected during deployment and recovery, and that a system can be temporarily withdrawn during a severe storm. These decisions connect ocean cleanup with operating and maintenance conditions, beyond the volume of plastic collected. [5]
What occupational prevention teams can learn
The case supports a specific question: what should change in risk assessment when a prototype becomes a continuing operation involving crews and suppliers?
A practical application is distinguishing environmental indicators from safety indicators. Tonnes removed, training participation and action follow-up answer different questions. Workshop attendance alone does not establish acquired competence or fewer injuries; the useful subject is the management system accompanying the project and the evidence used to evaluate it over time.
