Ocean Cleanup Team Unveils Solar Powered 'Interceptor' to Collect Plastic in Rivers
"We need to close the tap, which means preventing more plastic from reaching the ocean in the first place," Slat said.
Around eight million metric tons of plastic enters the world's oceans every year, where it threatens marine life. However, scientists like University of North Carolina, Asheville assistant professor Rebecca Helm warned that Ocean Cleanup's plan of scooping plastic from the ocean directly could also trap marine organisms. When the organization announced it had finally successfully collected plastic early in October, photographs revealed that this had indeed been the case.
Earlier this year I warned that @TheOceanCleanup would catch and kill floating marine life. This week they announce… https://t.co/D2bQ3m4q2x— Open Ocean Exploration (@Open Ocean Exploration)1570135850.0
Scientists have also argued that stopping plastic from entering the ocean in the first place would be more effective, Wired explained, and many were pleased that the non-profit seemed to be listening.
"I am really happy they finally moved toward the source of the litter,"Jan van Franeker of the Wageningen Marine Research institute told The Associated Press. "The design, from what I can see, looks pretty good."
Helm also tweeted that she was "encouraged" by the news.
Back in January I suggested The Ocean Cleanup move their devices closer to shore. I'm encouraged to see they are jo… https://t.co/Zfpoqf02fk— Open Ocean Exploration (@Open Ocean Exploration)1572116873.0
Slat said that 1,000 rivers dump around 80 percent of plastic that flows into the ocean, and he wanted to clean them all in the next five years. So far, the device is installed in rivers in Indonesia, Malaysia and Vietnam. A fourth will soon be installed in the Dominican Republic.
Fast Company explained how it works:
The new technology is designed to anchor to a riverbed, out of the path of passing boats. Like the system that the nonprofit designed for the ocean, which uses a large barrier that blocks part of the river to collect plastic as it floats by, the Interceptor has a floating barrier that directs trash into the system. The device is positioned where the greatest amount of plastic flows, and another device can be placed in farther down the river to catch trash that might escape the first Interceptor. A conveyor belt pulls the trash out of the water, and an autonomous system distributes it into dumpsters on a separate barge, sending an alert to local operators when the system is full and ready to be taken to a recycler.
On an average day, it can collect 50,000 kilograms (approximately 110,000 pounds), for a yearly total of approximately 20,000 tons.
So far, users are happy with the results.
"It has been used for one and a half months in the river and it's doing very well, collecting the plastic bottles and all the rubbish," Izham Hashim from the government of Selangor state in Malaysia said at the launch, as The Associated Press reported.
Wired pointed out that the device wasn't exactly original. Baltimore's Mr. Trash Wheel, which intercepts 200 tons of trash a year, predates it.
The Interceptor can clearly collect more, and it is intended to be mass produced and used in rivers around the world, instead of being designed for one particular location, like Mr. Trash Wheel.
"The scientific community has been saying for years that moving upstream is the way to correctly solve this problem," Adam Lindquist, director of the Waterfront Partnership of Baltimore's Healthy Harbor campaign, told Wired. "And certainly imitation is the greatest form of flattery."

Winter is supposed to be the best season for wind power – the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.

Ice buildup changes air flow around the turbine blade, which can slow it down. The top photos show ice forming after 10 minutes at different temperatures in the Wind Research Tunnel.

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.
theDOCK aims to innovate the Israeli maritime sector. Pexels<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>
theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner. Dudu Koren<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>
