The Town of North Hempstead has once again started up its oyster shell recycling initiative, which she helped launch in partnership with the Science Museum of Long Island and the Seatuck Environmental Association’s Half Shells for Habitat program.
Since its inception in 2018, Half Shells for Habitat has collected thousands of pounds of oyster shells that would otherwise end up in landfills. Instead, these shells are repurposed for rebuilding oyster reefs across Long Island, creating vital marine habitats, improving water quality, and helping protect shorelines from erosion.
“This program is a perfect example of how small changes in our daily lives — like what happens to an oyster shell after a meal — can have a big impact on our environment,” said Dalimonte. “By working together with local restaurants and community partners, we are restoring habitats, supporting biodiversity, and ensuring healthier bays for generations to come.”
Participating restaurants in the 2025 season include Louie’s Prime Steak & Seafood, Matteo’s of Roslyn, and the Manhasset Bay Yacht Club, with more establishments expected to join next summer.
Through the program, oyster shells are collected from participating restaurants and will be donated to Cornell Cooperative Extension of Suffolk County (CCE Suffolk) after a year of curing. CCE Suffolk uses oyster shells in their hatchery for oyster larvae to attach to and grow on, known as spat-on-shell. The spat-on-shell will be used in oyster seeding projects across Long Island, including Manhasset Bay.
The reintroduced oysters filter seawater (an adult oyster filters 50 gallons per day), provide habitat for fish and marine life, and act as natural barriers against storm surges. As shells dissolve, they also help mitigate the effects of coastal ocean acidification.
Dalimonte emphasized the importance of public engagement. “Every time someone orders oysters at one of these restaurants, they are helping rebuild our marine environment. It’s an easy and delicious way to make a difference.”
