Description

In February 2024, rrreefs launched its largest reef regeneration project in Pujada Bay, Philippines, covering over 100 m² of reef area in 2024 and more than 250 m² in 2025, with a hectare planned in 2027. Pujada Bay, a Marine Protected Area since 1994, faces significant threats such as overfishing and coral degradation. The project began with 820 3D-printed terracotta modules designed to promote coral growth and marine biodiversity recovery, with scientific monitoring conducted every six months by university partners. In collaboration with local partners, including the Department of Environment and Natural Resources, Davao Oriental State University, and the Coastal Conservation and Education Foundation, the project integrates community participation. Additionally, it combines coral reef regeneration with mangrove reforestation, partnering with Team Malizia, the Mama Earth Foundation, and Zurich Gruppe Deutschland to restore reefs and plant 9,000 mangroves at the same time, strengthening both community involvement and government support.

Impact & Result

A 3D-printed reef project in the Philippines restored marine life in Pujada Bay, boosting ecotourism and local supply chains through circular material sourcing. Within a year, coral recruits increased from 1,200 to over 4,000 across 100 m², with fish abundance 30% higher than at control sites and nine key species found only in the restored area. Over 40 locals joined reef and mangrove restoration efforts, while school programs reached eight institutions.

Our clients, business partners and employees are thrilled with our collaboration with rrreefs – a strong, passionate team and an innovative, scalable approach to healthy oceans.

Solution Spotlight

We rebuild dying coral reefs with a 3D-printed reef system made from pure clay, which has already shown excellent results for increasing the number of corals and fish. It creates habitat on all scales, is easy to handle, built by locals, and adaptable to local contexts, allowing for scalable decentralized implementation. With our reef regeneration packages, we enable companies with a footprint in or by the ocean to invest into ocean health to reach internal sustainability targets, drive engagement, or follow regulations. Our offering is a simple and effective solution, including impact reporting and storytelling material for at least 3 years. Fully scaled, rrreefs could protect 700 km of coastline with a 50m-barrier of regenerated reef within the next 10 years, that is 1% of reef-dependent coastal areas. Accompanying policy work will help protect these areas long-term and regenerate the vital services that healthy coral reefs provide to hundreds of millions of people.
