It depends on how the Oyster grow blocks are disposed of, on one hand, if they go to the dump, maybe that can help out there. It's when we reuse them with intention though, that we can get assurance of the benefits. Oysters will use TONS of different components as food sources, they seek carbon at the end of the day. Grown naturally, they normally grow on trees and don't get introduction into the soil to do this type of work
