A profitable investment that cleans the water and restores nature

Oyster Reef in Australia - The Nature Conservancy

Why invest in Oyster Heaven projects?

The transition to a stable ecology is desired by society and becoming baked into law.

Oyster Heaven sells resilience services to organisations or governments that are challenged by increasing risks and new regulations.

Oyster reefs are the most powerful ecosystem engineers in temperate waters. They can solve many ecological, operational, social and regulatory issues simultaneously and regeneratively.

Investing in oyster reefs offers a scalable, profitable and impactful solution. Here's how

We build oyster reefs to:

Filter and clean the water

for organisations that need to keep our seas clean and clear

Grow wild fish and habitat

for organisations that rely on a healthy ocean for their supply chain

Create "living concrete" breakwaters

for organisations that need to protect a coastline from erosion and flooding

Our 5 hectare oyster reefs deliver environmental and financial returns

The measurable value of the impact

Our oyster reefs act as natural breakwaters, reducing wave energy and protecting shorelines from erosion, offering a cost-effective alternative to hard infrastructure like concrete walls. At the same time, they create rich, biodiverse habitats that support fish populations, wading birds, and marine life.

By regenerating these habitats, we deliver long-term resilience for coastal communities, both environmentally and financially.

The measurable value of the impact

Oyster reefs naturally filter excess nutrients from the water, removing up to 3.5 tonnes of nitrogen and phosphate annually. This nutrient reduction helps prevent harmful algal blooms, improves water clarity, and supports the recovery of seagrass meadows and other marine life.

The environmental value is matched by financial returns: nutrient removal through oyster reefs addresses the last economically unreachable percentage of damage to water quality, offering savings for governments, water authorities, and industries facing nutrient regulations.

The measurable value of the impact

Our oyster restoration projects create meaningful jobs and new revenue streams in coastal regions that are often hit first and hardest by climate change.

We count on the local community and fishermen to be the stewards of the reef, from the deployment of our projects to the monitoring of its growth and development . This approach brings measurable value: it strengthens community resilience and opens up new income streams tied to environmental restoration, proving that climate action can drive inclusive, regenerative growth where it’s needed most.

The measurable impact

Building oyster reefs is the spark that ignites ecosystem regeneration.
Each reef we restore becomes a thriving underwater ecosystem, attracting and supporting an abundance of marine life and driving the rewilding of the sea.


Every restored reef creates habitat for up to 1 billion new sea creatures—from commercial fish to crabs, lobsters, and shrimp.


Healthy fish populations are a clear indicator of ecosystem recovery and a powerful reminder that nature-positive investments deliver real, measurable returns.
