Shell Recycling Alliance

Welcome to the Shell Recycling Alliance, where “no shell is left behind.”

Why recycle oyster shells?
Natural oyster shell is the best material on which to raise new oysters and restore oyster reefs. Scientist know that now, but for generations, used oyster shells were used to build roads, driveways and housing construction. More recently the shell has ended up in landfills. Today, is an extremely limited natural resource and a valuable one for improving waterways. Given the critical shortage of shell for use in restoring the Chesapeake Bay’s oyster population, the Oyster Recovery Partnership developed the Shell Recycling Alliance (SRA) to save this extremely limited natural resource.
