Arup, in partnership with RiverRecycle, is developing a digital twin of the Pasig River to generate critical insights for mitigating plastic pollution in one of the world’s most polluted waterways. The initiative, supported by the Asian Development Bank (ADB), aims to address a pressing environmental challenge that has global implications.
A Major Pollution Source
The Pasig River, which flows through Manila and connects Laguna de Bay to Manila Bay, is estimated to contribute over 6% of global plastic waste entering the oceans. Once a vital route for transport and trade, the river now represents a severe environmental and public health concern.
How the Digital Twin Works
The digital twin will integrate data from satellites, surveys, government agencies, and weather models, accounting for the tidal and rainfall patterns that influence water and plastic flow. This will enable spatial mapping of waste, helping inform targeted clean-up operations and long-term pollution prevention.
Partnership Perspectives
- Dr Serryn Eagleson, Arup’s Australia Digital Advisory Lead, highlighted that the project will turn complex data into actionable strategies for removing plastic from the river.
- Anssi Mikola, RiverRecycle’s CEO and Founder, stressed the importance of tackling plastic pollution “where it starts” to prevent it from reaching the ocean.
- Cai Li, Head of ADB-Korea Climate Technology Hub, noted that the project will drive the Pasig River rejuvenation initiative with science-backed planning and financing.
- David Moran, Arup’s APAC Digital Services Lead, emphasized that applying digital innovation to environmental problems will help create more liveable and resilient communities in the Philippines and globally.
