Slow-release conservation technology
We develop slow-release diffusion devices that deliver precision nutrition to coral reefs, kelp forests, seagrass meadows, and orchards, giving ecosystems exactly what they need, exactly when they need it.
As ocean temperatures rise, corals expel the algae living in their tissues, causing bleaching and, without recovery, death. Existing restoration efforts are too costly and too slow to match the pace of decline. Targeted nutrition may be the missing lever.
The Seafuser is a passive diffusion device that releases beneficial nutrients directly into the surrounding water. Positioned beside corals, it delivers a localised, calibrated supply right where the reef needs it most.
The Seafuser's core mechanism is supported by a growing body of published research from marine biologists worldwide. Our founder's own PhD research contributed directly to this field.
The same slow-release technology that nourishes coral reefs can regenerate terrestrial ecosystems too. Both products use the same proven mechanism, adapted for their environment.
A slow-release diffuser that delivers beneficial nutrients, such as ammonium, to coral reefs, seagrass meadows, kelp forests, and other marine ecosystems. Passive and scalable.
A biodegradable slow-release fertiliser device buried at planting time, delivering timed nutrition through a full growing season. Includes a soil conditioning blend.
The same slow-release diffusion principle adapted for land. The Terrafuser is buried at planting time in orchards, vineyards, and forestry plantations, delivering a timed-release package of nitrogen and soil amendments through an entire growing season. It can also be added mid-season by digging a small hole beside the root zone.
Beyond nitrogen, the Terrafuser contains a soil conditioning blend that releases passively into the root zone.
Oscar Crehan has spent over a decade working in marine conservation across Honduras, Malaysia, Fiji, Australia, and the Philippines, completing more than 700 coral reef research dives.
His PhD at Victoria University of Wellington revealed that the algae living within corals can become nitrogen-limited as temperatures rise, potentially triggering bleaching. That discovery became the scientific foundation for Ecofuser.
We are actively looking for NGOs, conservation operators, research institutions, and orchard and vineyard operators to trial our devices in real-world conditions.
