Weird idea but okay

Have you ever thought about what happens to the shells from a bowl of mussels or a plate of oysters?

In most parts of Australia, there’s a high chance they will end up in landfill.

But for the last two years, restaurants and seafood wholesalers in Geelong, south-west of Melbourne, have been donating their shells to a local shell recycling program.

Is this similar to the recycling of snail shells that’s been going on for many years?. New escargot is placed in old shells.

The first practical use for oyster shells in Australia that I know of, is where Sydney oyster shells were ground up and fired to make cement for building Sydney’s first buildings.

I like it. But is it stable enough without extra cementation?

Port Phillip Bay is subject to trawl netting for scallops. The trawling would tend to disperse any artificial reef that wasn’t nailed down.
