We are cleaning our oceans by restoring oyster reefs
Oyster reefs used to cover 20-30% of the North Sea . However, 150 years ago oysters were a popular cheap source of protein, and were eaten to virtual extinction without realising the damage this would cause on the environment.
Oysters are amazing creatures. They play a key role in their ecosystems, protect our shores from erosion, generate biodiversity, remove excess nitrogen and filter the water.
We need to bring oysters back to restore ocean health.
Our vision
Our team of outstanding scientists has researched the best possible way to help oysters, and developed a tool-set to revolutionise marine restoration, making it meaningful, cost-effective and scalable.
We’ve run lab and field tests in The Netherlands and Denmark to prove the efficiency of our tool-set with successful results.
Biodegradable. Climate Friendly. Low Cost.
The currently deserted sea floor is not a suitable place for oysters to live. They would sink in the sand and die.
So we created the Mother Reef.
These bricks will be the base that will cover the deserted sea floor. We worked out the best conditions to help baby oysters attach to the Mother Reefs and release them into the ocean back to where they used to be, and become home to millions of other creatures too.
Our projects can be deployed anywhere in the world where oyster restoration is needed. We partner with local fishing communities and provide them with a new revenue stream and type of work.
Fishermen will use their boats, equipment and knowledge of the water to plant the Mother Reefs into the ocean. They will also benefit from the improvement of the ocean health and biodiversity.
Thanks to the Mother Reef, the cost of restoring a reef will be significantly low at 0,25€ per oyster, compared to other projects with a cost varying between 20 to 1.000€ per oyster. Now marine restoration can finally reach large scale.
To fund more oyster restoration projects, we sell the ecosystem services that oyster reefs provide to businesses that want to become more sustainable and manage their environmental footprint. This way, for every reef we build, we can fund the next three, and so on.
Partners and supporters
At Oyster Heaven, we’re often asked a version of the same question: Can you really make a profit by restoring nature?
Our answer is simple: yes.
And not only can we, but we believe it’s the fastest and most scalable way to help restore nature.
Our world is changing rapidly, businesses are facing ever increasing pressures from supply chain disruptions, societal expectations and evolving environmental regulations.
Many people ask us at Oyster Heaven how we make money and why anyone would want to partner with us. At its core, we unlock value for the organisations that we work with by avoiding real costs. The costs we help to avoid come from three places in a business.
Avoiding fines and unlocking permits
Avoiding supply chain and operational disruption
Avoiding the cost of future compliance
For the past 150 years, oyster reefs have been declining toward near extinction. Today, the ocean needs bold, effective and fast action. At Oyster Heaven, we are doing exactly that: a nature-driven, cost-effective and measurable solution to rebuild marine ecosystems, restore coastal resilience, and boost biodiversity.
We’re proving that with the right tools, rewilding the ocean can move beyond small projects with limited funds and start working at the scale the ocean truly needs.
Ocean restoration has often been seen as a philanthropic effort, a cost rather than a value driver. But at Oyster Heaven, we’re changing that narrative and we’re proving that investing in improving nature doesn’t have to come at the expense of profit. In fact, restoring oceans can strengthen business models, build resilience, and unlock new opportunities.
Healthy oceans aren’t just an environmental issue; they are fundamental to economic stability, food security, and climate resilience. The smartest companies are realising that nature-based solutions are critical to securing their future.
The old story was one of taking. The new one is about giving back.
We’re proud to be part of the new narrative. From oysters as cheap street food to oysters as a keystone species to boost marine regeneration. From lost reefs to an oyster heaven.
Because rewilding the ocean isn’t just necessary. It’s urgent, and it’s already happening one Mother Reef at a time.
Can oyster reefs help real estate developers meet nitrogen regulations? Excess nitrogen pollution has stalled housing projects, but oyster reefs act as natural biofilters, removing nitrogen from water. At Oyster Heaven, we build large-scale reefs with our patented Mother Reef technology, restoring marine habitats while supporting sustainable development.
Make a measurable difference for the ocean today.
You can now adopt a Mother Reef and help restore 100 oysters!
