On Governor’s Island, the Billion Oyster Project recycles millions of oyster shells from neighborhood restaurants to rebuild oyster reefs that clean water, protect shorelines, and support marine life, creating a positive ripple effect for New York City waterways.
- Oyster shells from 75+ NYC restaurants are reused in reef restoration
- 200 million oysters raised to filter trillions of gallons of harbor water
- Project aims to restore 100 acres of reefs by 2035
What happened
The Billion Oyster Project on Governor’s Island collects discarded oyster shells from more than 75 New York City restaurants, curing them carefully before using them as a foundation for new oyster reefs. These shells provide a healthy environment for oyster larvae to grow before the young oysters are placed back into the harbor to revive lost reef habitats. Since its launch in 2008, the project has raised approximately 200 million live oysters using 3.2 million pounds of recycled shells.
These efforts have already restored 19 acres of reefs, enhancing New York Harbor’s natural ecosystem. The reefs filter tens of trillions of gallons of water and help absorb wave energy. With a goal of restoring 100 acres, the project expects to bring substantial environmental and economic benefits to the city by 2035.
Why it feels good
Oysters serve as a keystone species, meaning their presence supports the broader ecosystem's health and biodiversity. By filtering pollutants, oysters improve water quality, which benefits all marine life and enhances the harbor's overall environment. Additionally, oyster reefs reduce the energy of incoming waves, helping to protect shorelines from flooding — a critical service as climate change increases storm risks.
The project’s approach champions sustainability by turning restaurant waste into a valuable resource. By diverting oyster shells from landfills, the initiative exemplifies a circular economy model that supports local industries and environmental restoration simultaneously. Restaurateurs and residents alike can feel proud knowing that behind every oyster enjoyed is a contribution to revitalizing the city’s waterways.
What to enjoy or watch next
Keep an eye on the expansion of the Billion Oyster Project as it works toward its ambitious aim of restoring 100 acres of oyster reefs by 2035. This milestone promises to refresh the entire water volume of New York Harbor every three days, dramatically improving water quality and ecosystem resilience. Public engagement events and educational programs on Governor’s Island offer opportunities to learn more about oyster restoration and marine conservation.
For those curious about tasting the fruits of these efforts, New York restaurants partnering in this project offer sustainably sourced oysters that reflect this environmental success story. Watching how cities around the world adopt similar waste-to-reef efforts could also inspire greater appreciation for the role of nature-based solutions in urban sustainability.
