We're cleaning the ocean by restoring oyster reefs

Sustainability Reimagined

The situation

80% of sewage reaches our oceans untreated

The good news

Oysters can filter 200 litres of water per day and generate biodiversity

The bad news

Globally 85% of oyster reefs are gone

So what happened to the oyster reefs?

Why oyster regeneration is urgent and necessary

Oysters are a powerful species that generate biodiversity and play a key role for the environment. Not only that, but just like trees clean our air and capture carbon dioxide, oyster reefs clean the oceans and remove excess nitrogen from the water.

Today, oysters are in danger of extinction and only 15% of oyster reefs remain. Let’s give them a helping hand.

Yes, you read correctly…

Globally, only 15% of the oyster reefs remain

We care about our oceans as much as you do. Marine ecosystems play a vital role for the environment and over the last decades we’ve destroyed a big part of them.

Today, we understand this has to change. Reducing the environmental footprint of our society is the first step. But there’s much more we need to do to restore ocean health, and nature has the perfect ally for that: oyster reefs.

Did you know...?

  • Oyster reefs are one of the most natural and cost-effective ways to remove excess nitrogen from the oceans.
  • The water in the North Sea used to be clear and transparent.
  • Oysters only need a suitable hard surface to attach to.
  • Oyster reefs used to cover 20-30% of the North Sea. Now, it is the equivalent of a marine desert.

We need to help oysters help us

We’re bringing oysters back into the oceans by providing them with a new home, the Mother Reef bricks: a natural, cost effective, climate friendly and biodegradable artificial reef that will cover the deserted sea floor.
