Each year, the seafood industry discards more than 7 million tons of oyster shells that mostly wind up in landfills or are dumped into the ocean. Researchers find this practice “a collosal waste of potentially useful biomaterials,” which is why they have proposed two plans to reuse shells. One idea is to use the shells to restore damaged oyster reefs. The other is to crush them for applications in agriculture and engineering. Both plans require little time and money, and perfect examples of what we should expect from the circular economy of the future.
