We're raising funds to support our bioconcrete research and development - and restore oyster reefs.

Oyster reefs have declined by over 85% in the last two centuries due to overfishing, habitat destruction and disease. Along with their decline, there has been a decline in local biodiversity and an increase in coastal eutrophication.

We need your help to raise some more funds. Support us through our KickStarter campaign.
