SUEZ partners with The Nature Conservancy to help rebuild the reefs using oyster shells collected from seafood restaurants. The aim of the project: less waste, a restored habitat for native species and economic advantages for the marine industry.
Oysters are an integral part of marine ecosystems, improving biodiversity by improving water quality. The Port Phillip Bay project involved collecting used oyster shells from local restaurants and wholesalers. After collection, the shells were dried to eliminate pathogens, mixed with limestone rubble and placed on the seabed where young oysters were then able to gather. Since the start of the project, 1.5 hectares of shell reefs have been restored and 60 tonnes of shells have been recycled.
