Talk:The Ocean Cleanup

From Wikipedia, the free encyclopedia

Proposed content updates

Hello,

In line with the paid contribution disclosure requirements, I am proposing the following substantial updates to improve sourcing consistency, structure, and neutrality across the article.

Where appropriate, I have removed or adjusted content that relied primarily on primary sources, simplified overly detailed passages, and aligned wording more closely with independent secondary coverage.

For convenience, a consolidated draft reflecting all proposed changes is available here: https://en.wikipedia.org/wiki/User:Toometa/The_Ocean_Cleanup

This is only intended to provide a global overview; each proposed modification is detailed below.

Proposed update #1

Location: History section – opening sentence

−
Slat proposed the cleanup project and supporting system in 2012. In October, he outlined the project in a TED-talk.
+
Boyan Slat proposed the cleanup project and supporting system in 2012 in a TED-talk.

Rationale

Minor copy-edit to improve clarity and concision, without changing the underlying information or sourcing.

Proposed update #2

Location: History section – end of the opening paragraph

−
The barriers would direct the floating plastic to the central platform, which would remove the plastic from the water. Slat did not specify the dimensions of this system in the talk.
+
The barriers would direct the floating plastic to the central platform, which would remove the plastic from the water.

Rationale

Removes a non-informative sentence that merely notes the absence of a detail in the source, without contributing meaningful content.

Proposed update #3

Location: History section – 2014-2017: Initial prototype subsection - at the end of the first paragraph

Proposed addition:

According to later reporting, the development process ultimately involved testing 273 scale models and six distinct prototypes before the organization finalized the design that preceded System 001.[1]

Proposed update #4

Location: History section – 2014-2017: Initial prototype subsection - last paragraph

−
In May 2017, significant changes to the conceptual design were made: * Dimensions were reduced from 100 km (62 mi) to 2 km (1.2 mi), with the idea of using a fleet of 60 such systems. * Seabed anchors were replaced with [[sea anchor]]s, to drift with the currents, allowing the plastic to "catch up" with the cleanup system, and letting the system drift to locations with the highest concentration of debris. The lines to the anchor would keep the system in a U-shape. * An automatic system for collecting plastic was replaced with a system for concentrating the plastic before removal by support vessels.
+
In May 2017, significant changes to the conceptual design were made. This included reducing the length of the boom from 100 km to 2 km to increase unit scalability, replacing seabed anchors with sea anchors to allow it to drift with currents, and replacing the automatic system for removing accumulated plastic with a manual one.

Rationale

Reformatting for clarity and summary style, replacing an unnecessary bullet list with equivalent prose.

Source note

The existing source supporting the first clause is retained. Of the remaining sources, the Science reference is not necessary and has been removed. The three other sources are consolidated at the end of the paragraph.

Proposed update #5

Location: History section – System 001 subsection

Removal of the opening paragraph beginning with “Tests in 2018 led to sea anchors…”.

Rationale

The statements in this paragraph are either not clearly supported by the cited sources or rely primarily on a primary source, namely a video produced by the organization itself (World Maritime News).

Proposed update #6

Location: History section – System 001 subsection

−
On 9 September 2018, System 001 (nicknamed Wilson in reference to the floating volleyball in the 2000 film Cast Away) deployed from San Francisco.
+
On 9 September 2018, System 001 deployed from San Francisco.

Rationale

The nickname and pop culture reference are non-essential details and are not required in a summary-style history section.

Source note

The CNN source is removed as it is no longer necessary, and the remaining source is moved to the end of the sentence.

Proposed update #7

Location: History section – System 001 subsection

Add the following citation:

<ref>{{Cite news |last=Simon |first=Matt |title=Ocean Cleanup's Plastic Catcher Is Busted. So What Now? |url=https://www.wired.com/story/ocean-cleanups-plastic-catcher/ |access-date=2025-12-10 |work=Wired |language=en-US |issn=1059-1028}}</ref>

at the end of the sentence:

It consisted of a 600 m (2,000 ft) long barrier with a 3 m (9.8 ft) wide skirt hanging beneath it.[citation needed]

Proposed update #8

Location: History section – System 001 subsection

−
It was unmanned and incorporated solar-powered monitoring and navigation systems, including GPS, cameras, lanterns and AIS. The barrier and the screen were produced by an Austrian supplier.
+
It was unmanned and incorporated solar-powered monitoring and navigation systems, including GPS, cameras, lanterns and AIS.

Rationale

The supplier detail is non-essential and removed for summary-style consistency.

Proposed update #9

Location: History section

Move the “System 002 and 03” subsection above the “Interceptors 001–010” subsection.

Proposed update #10

Location: History section - “System 002 and 03 subsection” - first sentence

−
In July 2021, a new design called System 002, also known as "Jenny", was deployed in the Great Pacific Garbage Patch for testing.
+
In July 2021, a new design called System 002 was deployed in the Great Pacific Garbage Patch for testing.

Rationale

The nickname and pop culture reference are non-essential details and are not required in a summary-style history section.

Proposed update #11

Location: History section - System 002 and 03 subsection - first paragraph, last sentence

−
In October, the organization announced that the system had gathered 28,000 kilograms (62,000 lb) of trash. In October, the project announced plans for System 03, which would span up to 2.5 km (1.6 mi).
+
In October 2021, the organization announced that the system had gathered 28,000 kilograms (62,000 lb) of trash, and announced plans for System 03, which would span up to 2.5 km (1.6 mi).

Rationale

This change clarifies the timeline and removes unnecessary repetition, while fully preserving the information as supported by the source.

Proposed update #12

Location: History section - System 002 and 03 subsection - first paragraph

−
In May 2023, the project deployed its System 03 barrier, 2,250 meters long. The system included a retention zone where material is held before it is removed from the water, with the nets' mesh size there being increased from 10 to 15 mm. This is to allow marine life such as fish and turtles to escape, and to allow smaller creatures such as blue buttons and violet snails to pass through.
+
In May 2023, the project deployed its System 03 barrier, 2,250 meters long. The system incorporated design changes intended to reduce ecological impacts, including modifications to the retention area and the addition of a marine animal escape mechanism.

Rationale

The rewording aligns the statement more closely with the scope and level of detail supported by the available source (Wired).

Proposed update #13

Location: History section - System 002 and 03 subsection

Removal of the paragraph beginning with “System 03 has about 5× the capacity of System 002…”, as it is supported solely by a primary source.

Proposed update #14

Location: History section - Interceptors 001-010 subsection

Change the subsection title from “Interceptors 001–010” to “Interceptors”, as the individual numbering (including up to 010) is not supported by specific secondary references.

Proposed update #15

Location: History section - Interceptors subsection - first paragraph

−
In October 2019, The Ocean Cleanup unveiled a barrier for river cleanup, The Interceptor, to intercept river plastic and prevent it from reaching the ocean. Two systems were deployed in Jakarta (Indonesia) and Klang (Malaysia).
+
In October 2019, The Ocean Cleanup unveiled the Interceptor, a solar-powered system designed to remove plastic from rivers before it reaches the ocean. The first two Interceptor units were deployed in Klang (Malaysia) and Jakarta (Indonesia).

Rationale The revised wording better reflects the level of detail and phrasing supported by the cited source, while improving clarity and maintaining an appropriate summary style.

Source note

The DesignBoom source is sufficient to support the information contained in both sentences. The Maritime Executive source can be removed as it is not adequately aligned with the statements.

Proposed update #16

Location: History section - Interceptors subsection - second paragraph

−
In January 2020, flooding broke the barrier of Interceptor 001 in Jakarta. It was replaced with a newer model with a stronger screen, simpler design, and an adjustable better-defined weak link. A third Interceptor was deployed in Santo Domingo, in the Dominican Republic. In December, The Ocean Cleanup announced they would start large-scale production of the Interceptor series.
+
In January 2020, flooding broke the barrier of Interceptor 001 in Jakarta. It was replaced with a newer model with a stronger screen, simpler design, and an adjustable better-defined weak link.

Rationale

The removed sentences are either not clearly supported by the cited sources or rely on a broken link and what appears to be a primary source (a press release).

Source note

Retain only the EcoWatch source for the remaining paragraph, as it is sufficient to support the content.

Proposed update #17

Location: History section - Interceptors subsection - third paragraph

−
In July 2022, an Interceptor Original was deployed near the mouth of Ballona Creek in southwestern Los Angeles County, California. This was the first Interceptor Original installed in the United States, and the second of its kind to be deployed globally.
+
In October 2022, an Interceptor Original was deployed near the mouth of Ballona Creek in southwestern Los Angeles County, California. This installation was the first Interceptor Original in the United States.

Rationale

The existing wording is not supported by the cited source and relies on a primary source. The revised version reflects what is explicitly supported by independent sources and removes unsupported claims.

Source note

Remove the current source and add the following two at the end of the paragraph:

<ref>{{Cite web |last=Jacques |first=Justin |date=2023-07-05 |title=‘Interceptor’ Keeps More Than 75 Tons of Debris Out of Pacific Ocean |url=https://stormwater.wef.org/2023/07/interceptor-keeps-more-than-75-tons-of-debris-out-of-pacific-ocean/ |access-date=2026-02-11 |website=Stormwater Report |language=en-US}}</ref>

Proposed update #18

Location: History section - Interceptors subsection - last paragraph

−
In May 2022, the Ocean Cleanup trialed a new Interceptor called Trashfence on the Rio Las Vacas, a tributary of the Rio Motagua, in Guatemala. It was anchored to the riverbed, and the anchors washed out.[61] In April 2023, they returned with a pair of new Interceptors, at a point on the river with slower current, anchored to the riverbank. This was successful, and soon became their most prolific site; in its first year it removed 10,000,000 kg of trash from the river.[62]
+
In May 2022, the Ocean Cleanup trialed a new Interceptor called Trashfence on the Rio Las Vacas, a tributary of the Rio Motagua, in Guatemala. It was anchored to the riverbed, and the anchors washed out.[1] In 2023, The Ocean Cleanup deployed Interceptor 006 on the Río Las Vacas in Guatemala.[2]

Rationale

The removed material is not supported by the cited source and relies on a primary source (The Ocean Cleanup’s website). Unfortunately, the remaining content in this paragraph also appears to rely primarily on primary sources. I leave it to the reviewer’s discretion whether the entire paragraph should be removed on sourcing grounds.

Proposed update #19

Location: History section - at the end

Proposed addition

Addition of a new subsection titled “30 Cities Program”, with the following content:

During the United Nations Oceans Conference in 2025, The Ocean Cleanup announced an updated strategy in their mission to remove floating ocean plastic: the 30 Cities Program.[2]
The 30 Cities Program shifts The Ocean Cleanup’s strategy from addressing individual rivers to targeting entire urban areas with multiple polluted waterways. According to the organization, deploying Interceptors across 30 key cities could prevent up to 30 percent of river-borne plastic from reaching the ocean by the end of the decade.[3]
This evolution in strategy follows The Ocean Cleanup’s identification of the 1,000 rivers responsible for most of the world’s river-borne plastic,[3] as well as lessons learned from the deployment of their first 20 Interceptors.[2] In addition to intercepting plastic before it reaches the ocean, the 30 Cities Program also includes efforts to remove debris from nearby coasts, mangroves, and coral reefs, using data-driven mapping tools such as drones, AI image recognition, and GPS-tracked dummy plastics to guide operations.[2]
The first eight participating cities have been named as Bangkok (Thailand), Jakarta (Indonesia), Kuala Lumpur (Malaysia), Los Angeles (United States), Manila (Philippines), Montego Bay (Jamaica), Mumbai (India) and Panama City (Panama).[2][3]

Proposed update #20

Location: Research section

Complete removal of the subsection “Scientific findings.”

Rationale

The subsection relies almost entirely on primary scientific publications and summarizes their findings directly, without substantial independent secondary coverage discussing these results. Moreover, the content largely concerns broader environmental science topics rather than encyclopedic information about the organization itself.

Proposed update #21

Location: Research section

Removal of the subsection heading “Oceanic expeditions,” which is no longer necessary if Proposed update #20 is accepted, and modification of the first paragraph as follows:

−
In August 2015, The Ocean Cleanup conducted the Mega Expedition, in which a fleet of approximately 30 vessels, with lead ship R/V Ocean Starr, crossed the Great Pacific Garbage Patch and mapped an area of 3.5 million square kilometers. The expedition collected data on the size, concentration and total mass of the plastic in the patch. According to the organization, this expedition collected more data on oceanic plastic pollution than the last 40 years combined.
+
In August 2015, The Ocean Cleanup conducted the Mega Expedition, during which a fleet of around 30 vessels, led by the R/V Ocean Starr, collected plastic samples across the Great Pacific Garbage Patch in an effort to reassess the scale and composition of the debris.

Rationale

The removed sentence relied on a primary source and contained promotional language. The revised wording aligns more closely with the available independent source and avoids unsupported claims.

Source note Retain only the SFGate source at the end of the paragraph.

Proposed update #22

Location: Funding section - second paragraph

−
As of 2019, it was mainly funded by donations and in-kind sponsors, including Maersk, Salesforce.com chief executive Marc Benioff, Peter Thiel, Julius Baer Foundation, The Coca-Cola Company and Royal DSM.
+
Since 2019, the organization has been funded mainly through donations and in-kind sponsors, including Maersk, Salesforce.com chief executive Marc Benioff, Peter Thiel, Julius Baer Foundation, The Coca-Cola Company and Royal DSM.

Rationale

Minor wording adjustment for clarity and tense consistency, without altering the meaning or adding new information.

Proposed update #23

Location: Funding section - fourth paragraph

−
In October 2020, they unveiled a product made from plastic certified from the Great Pacific Garbage Patch, The Ocean Cleanup sunglasses, to help fund the continuation of the cleanup. They made 21,000 sunglasses, sold at €200 apiece. They worked with DNV GL to develop a certification for plastic from water sources and the sunglasses were certified to originate from the GPGP. The sunglasses were designed by Yves Béhar and manufactured by Safilo. They sold out in early 2022.

The sunglasses were designed by Yves Béhar and manufactured by Safilo. 21,000 units were made and put on sale at €200 apiece. They sold out in early 2022.

Rationale

Editorial adjustment for readability; no substantive change.

Proposed update #24

Location: Funding section - sixth paragraph

−
In 2022, Kia signed a seven-year deal to become a global partner of The Ocean Cleanup through funding and in-kind contributions. The partnership will fund the construction of a new Interceptor and will allow for recycled plastics to be used in the manufacturing process of Kia.
+
In 2022, Kia became a global partner of The Ocean Cleanup, providing funding and in-kind contributions to support its cleanup operations.

Rationale

The current paragraph relies entirely on a primary source and includes claims that are not clearly supported by that source. The proposed revision replaces the paragraph with wording based strictly on an independent secondary source (Newsweek), aligning the content with what is explicitly reported there and removing unsupported detail.

Source note

Replace the current primary source with the following secondary source:

<ref>{{Cite news |last=Falkenberg-Hull |first=Eileen |date=2025-04-15 |title=Cleaner Water: Kia and The Ocean Cleanup Partner to Green the Planet |url=https://www.newsweek.com/2025/05/02/cleaner-water-kia-ocean-cleanup-partner-green-planet-2056497.html |archive-url=http://web.archive.org/web/20250426113426/https://www.newsweek.com/2025/05/02/cleaner-water-kia-ocean-cleanup-partner-green-planet-2056497.html |archive-date=2025-04-26 |access-date=2026-01-16 |work=Newsweek |language=en}}</ref>

Proposed update #25

Location: Funding section - at the end

Proposed addition

In 2024, Coldplay announced that a vinyl version of their new album, Moon Music, would be made from plastic recovered by The Ocean Cleanup in Rio Las Vacas, Guatemala.[4]

Proposed update #26

Location: Efficacy issues and possible negative impacts section - at the end of the second paragraph

Proposed addition

−
A modelling study concluded that it is currently impossible to determine how damaging at-sea plastic removal strategies (such as those of The Ocean Cleanup) would be for marine life, with impacts potentially ranging from mild to severe.
+
A modelling study concluded that it is currently impossible to determine how damaging at-sea plastic removal strategies (such as those of The Ocean Cleanup) would be for marine life, with impacts potentially ranging from mild to severe. In 2025, The Ocean Cleanup published a peer-reviewed environmental assessment of its activities, which concluded that, according to the authors, the modeled benefits of ocean plastic removal outweighed the associated environmental costs, including greenhouse gas emissions and ecosystem impacts.

Source note

Use the following source to support the addition:

<ref>{{Cite journal |last=Egger |first=Matthias |last2=Booth |first2=Andy M. |last3=Bosker |first3=Thijs |last4=Everaert |first4=Gert |last5=Garrard |first5=Samantha L. |last6=Havas |first6=Vilma |last7=Huntley |first7=Helga S. |last8=Koelmans |first8=Albert A. |last9=Kvale |first9=Karin |last10=Lebreton |first10=Laurent |last11=Niemann |first11=Helge |last12=Pang |first12=Qiaotong |last13=Proietti |first13=Maira |last14=Puskic |first14=Peter |last15=Richon |first15=Camille |date=2025-05-27 |title=Evaluating the environmental impact of cleaning the North Pacific Garbage Patch |url=https://www.nature.com/articles/s41598-025-00619-w |journal=Scientific Reports |volume=15 |issue=1 |pages=16736 |doi=10.1038/s41598-025-00619-w |issn=2045-2322 |language=en }}</ref>

Rationale

The proposed addition aims to provide contextual balance within the paragraph. It is acknowledged that the cited source is a primary source (a scientific study authored by members of the organization). However, the preceding sentence in the paragraph also relies on a primary scientific study that has not been discussed in independent secondary coverage. For reasons of consistency in sourcing standards, if the present addition is deemed inappropriate due to its reliance on a primary source, it may also be appropriate to reassess the preceding statement on similar grounds. I leave this to the reviewer’s discretion.

Proposed update #27

Location: History section

Replace with a more recent freely licensed image available on Wikimedia Commons: commons:File:Boyan_Slat.jpg

Proposed update #28

Location: Lead section

−
The Ocean Cleanup is a nonprofit environmental engineering organization based in the Netherlands that develops and deploys technology to extract plastic pollution from the oceans and to capture it in rivers before it can reach the ocean. Their initial focus was on the Pacific Ocean and its garbage patch, and extended to rivers in countries including Indonesia, Guatemala, and the United States. The Ocean Cleanup was founded in 2013 by Boyan Slat, a Dutch inventor who serves as its CEO. It develops both ocean and river based catch systems. Its ocean system consists of a funnel shaped floating barrier which is towed by two ships. The ocean system is deployed in oceanic gyres to collect marine debris. The project aims to launch 10 or more approximately 2 km-long (1.2 mi) systems which they predict could remove 50% of the debris in the Great Pacific Garbage Patch five years from deployment. The river system consists of a variety of floating barriers and extraction systems which are anchored within rivers or at rivermouths. The Ocean Cleanup also publishes scientific papers, and estimates that "1% of worlds rivers (~1,000 rivers) are responsible for 80% of the pollution in the world's seas". They aim to deploy their river systems in these 1,000 rivers. As of January 2026, the organization has removed over 50 million kilograms (50,000 metric tons) of trash from rivers and the Great Pacific Garbage Patch.

The Ocean Cleanup is a nonprofit organization based in the Netherlands that develops and scales technologies to remove floating plastic pollution from oceans and rivers. Founded in 2013 by Dutch inventor Boyan Slat, the organization conducts research on ocean and river plastic pollution, designs offshore cleanup systems deployed in the Great Pacific Garbage Patch, and operates a range of river-based Interceptor devices in multiple countries. Since its early feasibility studies and prototype tests between 2014 and 2017, The Ocean Cleanup has released several generations of ocean systems, including System 001, System 002, and the larger System 03. In parallel, the organization has expanded its river program with deployments in Asia, the Americas, and the Caribbean. The project has received significant public attention for both its ambitious goals and the technical challenges it has encountered, and it has also published scientific research on the movement and accumulation of plastic in marine environments.

Rationale

The current lead is overly detailed, includes claims not clearly reflected in the body of the article, and departs from standard lead structure.

The revised version condenses the content, removes promotional or predictive elements, and aligns strictly with material that is covered and sourced in the body of the article, in order to ensure compliance with summary style and neutrality.
