More than 70 New York City restaurants are pouring their discarded shells into the Billion Oyster Project, through which students recycle and transform them into healthy reefs in once-toxic waters.
Owens says the project is not just smart for sustainability; it's also good for business. Recycling shells significantly reduces carting expenses, something all NYC restaurants must pay for by the bag. "Recycling them into the reef is a huge savings," he says.
