The Ocean Cleanup Launches 30 Cities Program to Cut Ocean Plastic Pollution from Rivers by One Third by 2030
The Ocean Cleanup, the international non-profit with the mission to rid the world’s oceans of plastic, has announced, at the UN Ocean Conference (UNOC), its plan to rapidly expand its work to intercept and remove ocean-bound plastic pollution.
The 30 Cities Program will scale the organization’s proven Interceptor™ solutions across 30 key cities in Asia and the Americas, aiming to eliminate up to one third of all plastic flowing from the world’s rivers into the ocean before the end of the decade.
This evolution follows five years of learning through pioneering deployments across 20 of the world’s most polluting rivers and represents a key next step in the organization’s mission and the global fight against ocean plastic pollution.
With the 30 Cities Program, The Ocean Cleanup will transition from single river deployments to citywide solutions, tackling the main plastic emitting waterways within each selected city. This follows a key learning from deployments in Kingston, Jamaica, which showed it is possible to scale faster when projects encompass whole cities, as the same set of partners can be involved with all deployments.
To date, The Ocean Cleanup has already prevented 29 million kilograms of trash from reaching the ocean. The organization currently intercepts an estimated 1–3 percent of global river-borne plastic emissions. With the first 20 river deployments close to being fully operational, it is now poised to reduce the plastic pollution flowing into the ocean from rivers by up to a third.
“When we take on an entire city, instead of individual rivers, we can scale faster, reduce costs, and maximize impact,” said Boyan Slat, Founder and CEO of The Ocean Cleanup. “Our analysis shows that strategically deploying Interceptors across just 30 carefully chosen cities can stop up to a third of river plastic pollution worldwide. This is the next big leap toward our ultimate goal of a 90 percent reduction in global ocean plastic pollution.”
City-by-city: a Faster Path to Scaling
Using the latest scientific modeling and on the ground experience, The Ocean Cleanup identified 30 major plastic polluting coastal cities which include:
• Panama City, Panama – First deployment to go live in the coming months.
• Mumbai, India – Mapping of all waterways completed; preparations for first deployments underway.
Furthermore, the organization is developing plans to expand on its existing work to all polluting rivers in:
• Manila, Philippines; Montego Bay, Jamaica; Jakarta, Indonesia; Kuala Lumpur, Malaysia; Bangkok, Thailand and Los Angeles, U.S.A.
Other cities will be announced once the necessary partnerships and agreements are in place. Planning and fundraising activities are underway for all 30 cities. To realize these ambitious plans, the organization is currently also expanding its engineering and operational capacity.
Data Driven Restoration at Scale
Before Interceptors are deployed, each city project begins with an intensive analysis phase. Aerial drones, AI-powered image analysis, and GPS-tagged “dummy” plastics are used to chart every visible waterway and track how waste moves from streets to sea. These real-time insights guide optimal Interceptor placement and provide a public baseline against which progress can be measured.
Alongside intercepting new plastic, the 30 Cities Program will also remove debris from nearby coasts, mangroves, and coral reefs. This twin-track approach—shutting off the tap while clearing the legacy pollution—enables The Ocean Cleanup to achieve long-term impact, which includes the restoration of fish nursery habitats, boosting coastal tourism, and strengthening of natural storm surge defenses for local communities. Alongside local partners, the organization also advocates for improvements in waste management and awareness raising amongst communities.
Completing the First 20 Rivers
While laying the foundation for the 30 Cities Program, The Ocean Cleanup is also nearing completion of its first 20 river projects. The next landmark achievement—expected as soon as the second half of this year—is in the western Caribbean, where the team aims to resolve the plastic pollution problem in the Gulf of Honduras by intercepting the trash feeding into this body of water.
A Stepping Stone Toward a 90 Percent Reduction
The 30 Cities Program represents the first major scaling step in The Ocean Cleanup’s journey to eliminate 90 percent of floating ocean plastic pollution. In parallel, efforts are continuing to remove plastic from the Great Pacific Garbage Patch. Whilst extraction operations are currently on hiatus, work to deploy cutting edge technologies to map the “hotspots”, or areas of intense plastic accumulation, in order to make future extractions more efficient and economical, is ongoing.
By combining river interception and coastal cleanup with its offshore cleanup systems targeting legacy pollution that’s already in the ocean, the organization is charting a path to turn off the tap and mop up the mess.

Far from the usual tourist trails, on a small island in the Northern Moluccas, lies a place of extraordinary beauty: Nabucco’s Spice Island Resort. Nestled between dense tropical jungle and a powdery white sand beach, the resort offers a peaceful escape immersed in nature at its purest. With panoramic views of the turquoise sea and direct access to some of Indonesia’s most untouched reefs, it’s a dream come true for those seeking tranquility above and adventure below the surface.
The resort features just 16 spacious beachfront bungalows, each only steps from the ocean. At its heart is a beautifully designed open-air restaurant, built entirely from natural materials, where guests can enjoy a diverse selection of Indonesian and international cuisine.
But what truly sets Nabucco’s Spice Island Resort apart is the underwater world that surrounds it. The reefs of the Northern Moluccas are among the most pristine and biodiverse in all of Indonesia – and remarkably, they remain largely untouched. Thanks to the remote location, dive boats are often the only ones around, giving divers the rare privilege of exploring vibrant coral gardens, dramatic walls, and colorful drop-offs in complete solitude.
Marine life here is nothing short of spectacular. Blacktip reef sharks are spotted on nearly every dive, while nutrient-rich walls attract sea turtles, schools of jacks, and bumphead parrotfish. For macro enthusiasts, the area is a treasure trove of rare and photogenic species, including pygmy seahorses, ghost pipefish, nudibranchs, frogfish, leaf scorpionfish, and several types of octopus and shrimp.
One of the region’s most extraordinary highlights is the Halmahera Walking Shark, a rare species endemic to this part of Indonesia. First described by scientists only in recent years, this small shark is unlike anything else in the ocean. Rather than swimming, it uses its muscular pectoral and pelvic fins to “walk” along the seabed. These elusive yet fascinating creatures are most often encountered on night dives – and witnessing one in the wild is a truly unforgettable experience.
The reefscapes surrounding Spice Island Resort are equally impressive. Flourishing hard coral formations spread across the seabed, interspersed with vivid sponges, large sea fans, and colorful soft corals. The biodiversity is astonishing, and the visual spectacle underwater is a dream for photographers. Most importantly, the reefs here are healthy—a rare treasure in today’s marine environment. With minimal tourism and careful management, the ecosystem remains intact, vibrant, and teeming with life.
Nabucco’s Spice Island Resort is more than just a dive destination – it’s a retreat for those seeking peace and a haven for underwater explorers looking to experience the authentic magic of Indonesia’s last true frontier.

Two weeks ago, during World Oceans Day weekend, over 200 divers from at least 15 different BSAC clubs descended on Cornwall to be part of the Kernow Dive Festival 2025. Ten RIBs and their skippers collectively carried out just shy of 300 boat dives over the weekend, with divers of all levels participating in the scheduled diving.
Not only was it fantastic to see the diving community come together to celebrate diving on World Oceans Day, but the weekend also raised funds for DDRC Healthcare Plymouth and hopefully increased awareness of their work.
The plight of UK chamber facilities has been in the spotlight recently due to the planned reduction in the number of hyperbaric chambers available to scuba divers in England.
With their number set to be cut from eight to just three, the pressure on the remaining chambers is a serious concern. Yet many divers starting out are unaware of the facilities available when things go wrong, or the ongoing research that takes place at these centres to make diving safer for everyone.
DDRC leads the field in dive medicine research, treating decompression illness and maintaining the national 24/7 helpline. Their work is essential for keeping all divers safe, and we’re proud to help raise awareness of their fantastic efforts.
Last year, the Kernow Dive Festival raised over £7,300 for DDRC Healthcare in Plymouth; this year, we’ve raised a phenomenal £8,550! This brings the total raised by the festival for DDRC to £69,760!
This is primarily thanks to the incredible support the event receives from the attending clubs, the diving industry, and local businesses, who contribute significantly to the raffle and auction fundraising activities on Saturday night.
The following businesses deserve a special mention, and we can’t thank them enough for their generosity. In no particular order:
North Coast Diving donated a full-day charter
O’Three Ltd donated a 50% drysuit voucher and a semi-dry
Kent Tooling Diving Products donated two of their reels
Seaways Diving and Suunto UK donated a Suunto Diving D6i Novo Zulu dive computer between them
Scubapro donated a pair of their Seawing Supernova fins
MARES – just add water donated three of their bags
Discovery Divers Plymouth Ltd donated a day’s diving for two divers
Seaways Diving and Engineer Aftercare Caravan, Campervan & Motorhome Warranty donated vouchers for cylinder testing and £100 off at Seaways
Liquid Sports donated a BigBlue 1300NP torch and some Sharkskin caps
Cressi donated a pair of their Origin fins
AP Diving donated an assortment of items, including flasks, dry bags, mugs and beanies
DDRC Healthcare donated a 40m chamber dive and facilities tour for up to 8 people
Dive Signs donated a selection of their Smart Emergency, MOD, and Gas Analysis sticker packs
Sharp’s Brewery donated a voucher for either a 5-litre mini cask of Doom Bar or an 8-pack of cans
Scuba Ry Divers donated a snorkel set
BSAC – British Sub-Aqua Club donated two digital SDC training packs
Porthkerris Divers donated T-shirts
Two local businesses also helped keep the divers warm and well-fed:
Penryn Joinery donated a van load of heating fuel briquettes to keep everyone warm on Saturday night, and Firewood Supplies Ltd near Penzance kindly donated several large bags of restaurant-grade charcoal for the Kernow Dive Festival BBQ.
We also need to give a big shout-out to local ghost gear recovery charity Fathoms Free, which supported the fundraising weekend with its recently refurbished RIB and experienced skipper, Jules!
Their RIB, Stingray, was the first boat out and the last boat in on both days. They said it was fantastic to support such a great cause and were pleased to help raise awareness and funds for DDRC, which provides a vital service to all divers in the region—including those who volunteer for the charity during ghost gear recoveries.
The BSAC South West Region clubs that played a major role in this year’s event included:
Bude Dive Club, whose members handled catering and, along with Peninsula Sub Aqua Club, ran the control room and slipway like a well-oiled military operation.
Peninsula Sub Aqua Club (BSAC), whose members oversaw much of the shotting of the dive sites and planned the weekend’s diving. They also have a small quiz team, known amongst other names as the Four Skin Divers, who attend Tricky’s at the Tolgus Inn every fortnight for quiz nights. Over the last 12 months, they collated all their winnings and donated £230 to the fundraising efforts!
Totnes Sub Aqua Club, whose members managed the finances and insurance and once again ran the record-breaking raffle!
A special thanks to Ponsandane Camping, who once again gave us VIP treatment, let us take over the site for the weekend, and provided secure boat storage for all attending clubs.
We’re also incredibly grateful to the team at Penzance Harbour for supporting the event year after year.
Huge thanks to everyone who helped organise the weekend, to the businesses and individuals who donated to the fundraising efforts, and to the 200+ people who took part!
It was truly a fantastic event. Despite the less-than-ideal weather, everyone had a great time—and a record amount of money was raised. Planning for next year is already underway!
