Can I put shrimp shells in the disposer?

A food waste disposer, also known as a garbage disposal, grinds scraps right in the sink: here is what happens with shrimp shells.

How it behaves in the disposer

Shrimp shells: what matters here is how hard it is, not how big, because the plate works by impact against the ring, much like a pestle. This needs a top-range model: the piece is picked up again and again until it is small enough to flow. Prawn shells are thin but springy: fine on the top models, a few at a time. Crab and lobster shells are not, they are too hard. If you produce a lot of it, it is worth checking your water utility’s rules.
