Environment Undersecretary Jonas R. Leones and Dutch nonprofit founder Boyan Slat signed their names on a five-year memorandum this week in Quezon City, cementing a partnership that will soon send 21 solar-powered interceptors into the murky waters of the Pasig River and Manila Bay. What makes this moment significant isn't just the paperwork—it's what these machines will do. The Ocean Cleanup's large-scale interceptors, already deployed across 10 countries worldwide, have collected more than 52 million kilograms of trash from aquatic environments as of April 2026. Now the Philippines is joining that fight, and the water that flows past one of Southeast Asia's most populous cities will never be the same.
The partnership between the Department of Environment and Natural Resources and The Ocean Cleanup represents a direct response to President Ferdinand R. Marcos, Jr.'s urgent directives to restore the Pasig River—part of the broader Pasig Bigyang Buhay Muli (Giving Life Anew to the Pasig) initiative. The first deployment is scheduled to begin in Meycauayan, Bulacan in the coming weeks, marking the start of what could be a transformative chapter for waterways that have absorbed decades of industrial and urban runoff.
This matters because the Pasig River and Manila Bay are among the world's most visible examples of plastic pollution's toll on urban waterways. The interceptors being deployed are not passive devices—they are automated, solar-powered systems designed specifically to work in river and coastal environments where waste accumulates. The technology operates without fuel consumption or manual intervention, allowing for continuous collection across the target areas. By placing 21 of these devices strategically throughout the system, the partnership aims to capture plastic before it reaches the open ocean, where it fragments into microplastics and persists for centuries.
The Ocean Cleanup's larger vision frames this work within its 30 Cities Program, an ambitious initiative to eliminate up to one-third of all plastic waste flowing from the world's rivers into the ocean by the end of the decade. Manila Bay is one of those 30 critical nodes in the global effort to reduce ocean-bound plastic pollution. Environment Secretary Juan Miguel T. Cuna framed the agreement as part of the administration's environmental recovery strategy—a recognition that restoring urban waterways is now a government priority, not simply a nonprofit concern.
What the interceptors collect won't disappear—the waste will be properly managed and processed, diverting it from marine ecosystems where it would otherwise accumulate. For a river system that has struggled with pollution for generations, the arrival of this technology represents not a silver bullet, but a concrete, measurable step forward. The five-year term allows for sustained effort and adaptive management as the system encounters different conditions across seasons and years.
The partnership also signals a shift in how countries are responding to plastic pollution: by embracing proven technological solutions developed specifically for urban waterway challenges. The 52 million kilograms already removed from global waters serves as proof that the interceptor model works. Now, Pasig River residents and Manila Bay fishers will witness that proven technology working in their own waters, turning a longtime symbol of environmental neglect into a site of active restoration.
