The Department of Environment and Natural Resources (DENR) has formalized a five-year partnership with The Ocean Cleanup, a global nonprofit, to combat plastic pollution within the Pasig River and the wider Manila Bay region. Signed this past Thursday, the agreement integrates international technical expertise with local government initiatives to intercept waste before it reaches the marine environment.
A Strategic Environmental Push
The initiative centers on the deployment of solar-powered, automated and high-capacity interceptor technology designed to capture the heavy waste loads prevalent in the Pasig River system. This project acts as a technical component of the government’s “Pasig Bigyang Buhay Muli” (PBBM) program, which aims to revitalize the river for navigation and urban renewal.
Environment Secretary Juan Miguel Cuna noted that the partnership marks a shift in how the nation addresses its waste burden, moving beyond traditional methods toward a more proactive, technological approach. The endeavor is also aligned with the “upstream regulatory push” mandated by Republic Act 11898, or the Extended Producer Responsibility Act, which compels corporations to manage the lifecycle of their plastic packaging.
Did You Know? The Ocean Cleanup’s involvement in Manila is part of its ambitious “30 Cities Program,” which aims to deploy waste-interception solutions across 30 major cities in Asia and the Americas to eliminate up to one-third of all river-borne plastic flowing into the oceans by the end of the decade.
Deployment and Future Implications
Preparations for the rollout are already in motion, with nearly 100 potential sites having undergone surveys to ensure maximum impact. While the Pasig River is the primary focus, the initiative will also see the installation of an interceptor barrier at the Meycauayan River in Bulacan.
Expert Insight: By combining real-time scientific data exchange with physical interceptors, this partnership could establish a repeatable model for urban waterway restoration. The success of this project may hinge on how effectively the “upstream” corporate responsibility mandates under local law are integrated with the “downstream” physical cleanup efforts to prevent future pollution at the source.
Looking ahead, the deployment of these automated systems may provide the government with a clearer baseline situational analysis of plastic waste flows. If the initial barriers prove successful, the data gathered could potentially inform future environmental policies and urban planning decisions across other major Philippine waterways.
Frequently Asked Questions
What is the main goal of the partnership between the DENR and The Ocean Cleanup?
The partnership aims to address plastic pollution in the Pasig River and Manila Bay region by deploying solar-powered, automated interceptor technology to catch waste before it reaches the ocean.

Where will the cleanup technology be deployed?
The organizers have surveyed almost 100 sites for maximum impact. While the project focuses on the Pasig River, the first interceptor barrier is slated for the Meycauayan River in Bulacan.
How does this project relate to existing Philippine laws?
The initiative serves as a technical pillar for the “Pasig Bigyang Buhay Muli” program and supports the “upstream” regulatory requirements of the Extended Producer Responsibility Act (Republic Act 11898), which mandates that companies recover and recycle their plastic packaging.
How do you believe the integration of global technology and local policy will shift the long-term health of our urban waterways?
