The Philippine government has formally entered into a five-year partnership with the global non-profit The Ocean Cleanup, signing an agreement aimed at removing floating waste from the Pasig River and deploying low-cost innovative technologies for data exchange and baseline analysis. This collaboration, signed by the Department of Environment and Natural Resources (DENR), represents a two-front strategy that combines direct river cleanup with upstream regulatory measures. For residents and businesses in Metro Manila, this means a tangible, large-scale intervention is finally being tested on one of the world’s most polluted waterways, moving beyond policy discussions into active removal.
The scale of the problem is immense. The Manila Bay Region, including the Pasig River System, is one of the key waterways The Ocean Cleanup is set to deploy in as part of its 30 Cities Program, which aims 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 initiative is a direct response to the urgent directives of President Ferdinand Marcos Jr., serving as a vital technical pillar for the administration’s flagship ‘Pasig Bigyang Buhay Muli’ (PBBM) project. For context, the challenge of plastic waste in the country is deeply tied to consumer habits, as explored in our analysis of sachet waste and brand responsibility.
How the River Cleanup Technology Works
This is not just about installing machines. The partnership is designed to complement the government’s upstream regulatory push under Republic Act 11898, the Extended Producer Responsibility Act, which requires large companies to recover and recycle the plastic packaging they produce. The technology itself has a proven track record: The Ocean Cleanup has deployed 21 Interceptors in 10 countries and to date has collected more than 52 million kilograms of trash from aquatic environments as of April 2026.
Background: The Pasig River and the PBBM Project
The Pasig River has been a focal point of environmental concern for decades, choked with industrial discharge, household waste, and plastic debris. The ‘Pasig Bigyang Buhay Muli’ (PBBM) project is the administration’s flagship effort to rehabilitate the waterway, and this partnership with The Ocean Cleanup provides a critical technical pillar for that vision. Preparations for deployments across the Manila Bay region are already underway, with The Ocean Cleanup having surveyed nearly 100 sites and working with the DENR to identify key deployment locations.
In addition to strategic sites along the Pasig River currently being identified by the PRCMO, The Ocean Cleanup is set to deploy its first Interceptor barrier in the Meycauayan River in Bulacan. This location is significant because Meycauayan is known for its industrial activity and has been identified as one of the world’s most polluted rivers. The choice reflects a strategic approach: tackle the worst sources first. The problem of agricultural runoff also contributes heavily to water pollution, a dynamic we examine in our piece on overgrazing and its impact on water quality.
What Gets Missed: The Nuances of River Cleanup
→ Scroll right to see all columns
| Factor | What It Means | Why It Matters |
|---|---|---|
| Continuous waste load | The Pasig River carries a heavy, uninterrupted flow of trash | Technology must be adapted for high-volume, non-stop capture, not just periodic cleanup |
| Knowledge transfer timeline | 5-year partnership with PRCMO | Local capacity must be built within this window to ensure sustainability after the agreement ends |
| Site selection complexity | Nearly 100 sites surveyed; only key locations chosen | Not all polluted areas will be covered; strategic triage is necessary |
| Upstream vs. downstream | Law targets production; Interceptors target existing waste | Without effective EPR enforcement, Interceptors may be overwhelmed by new waste |
One common misunderstanding is that a single cleanup technology can solve the problem alone. The reality is more complicated. The Interceptors are designed to capture floating waste, but they cannot address submerged debris, microplastics, or chemical pollutants. Furthermore, the success of the technology depends heavily on the upstream regulatory environment. If the Extended Producer Responsibility Act is not effectively enforced, the volume of new plastic entering the river could outpace the Interceptors’ capacity. The partnership is supported by Energies PH, but the broader challenge involves the entire waste management ecosystem, from farm runoff to ocean pollution.
Another nuance is the geographic scope. While the Pasig River and Meycauayan River are initial priorities, the 30 Cities Program aims to scale across Asia and the Americas. For the Philippines, this means that success in Manila Bay could serve as a model for other urban waterways, but it also means that resources are finite and not every polluted river will receive an Interceptor. The decision to focus on the Meycauayan River first reflects a judgment call: target the worst sources for maximum impact, even if other areas remain untreated for now.
Practical Guide: What This Means for Communities and Businesses
For Local Government Units (LGUs)
LGUs along the Pasig River and Meycauayan River should prepare for coordination with the Pasig River Coordinating and Management Office (PRCMO). The knowledge transfer component of the partnership means that local officials and technical staff will receive training on Interceptor operations and data analysis. LGUs should identify potential deployment sites, ensure access for equipment installation, and align local waste management plans with the national EPR framework. The partnership’s success depends on local cooperation in maintaining the barriers and preventing new waste from entering the river upstream.
For Businesses Subject to EPR
Companies covered by Republic Act 11898 should view this partnership as a signal that enforcement is intensifying. The law requires large businesses to recover and recycle the plastic packaging they produce. With the government now investing in visible cleanup infrastructure, the pressure to comply with EPR obligations will likely increase. Businesses should audit their plastic packaging, establish recovery programs, and document compliance to avoid penalties. The Interceptors will capture waste, but the law’s intent is to reduce the amount of waste that reaches the river in the first place.
For Residents and Community Groups
Individuals can support the cleanup by participating in local waste segregation programs and reporting illegal dumping. The Interceptors are automated, but they still require community cooperation to prevent recontamination. Community groups can also engage with the PRCMO to learn about monitoring data and advocate for additional cleanup sites. The partnership includes a rigorous scientific data exchange, meaning that progress will be measurable and transparent. Residents should watch for public reports on waste volumes collected and river health indicators.
Future-Phase: Scaling the 30 Cities Program
The 30 Cities Program, launched last year, aims to scale Interceptor solutions across 30 key cities in Asia and the Americas. For the Philippines, this means that if the Pasig River and Meycauayan River deployments prove successful, additional cities could be added. The goal is 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 is an ambitious target, and the Philippine partnership will serve as a critical test case. The organization, founded in 2013 by Boyan Slat, now employs a multi-disciplined team of approximately 200 people and is headquartered in Rotterdam, the Netherlands, with international operations in 10 countries.

Closing
The partnership between the Philippine government and The Ocean Cleanup represents a concrete step toward addressing water pollution, but it is not a silver bullet. The technology is proven, the data-sharing framework is rigorous, and the alignment with the Extended Producer Responsibility Act provides a regulatory backbone. What remains to be seen is how effectively the upstream enforcement and local cooperation will support the downstream cleanup. For now, the focus is on the Meycauayan River and the Pasig River, with the potential to scale if the model works.
