Giving waste value with the NSW Oyster Industry

OceanWatch have been working in partnership with the NSW oyster industry to transition the industry to a more resilient and sustainable business model by tackling one of the sector’s biggest post-flood challenges: management of discarded oyster farming infrastructure and shell waste.

The project was developed in response to industry losses of $17 million from stock loss, infrastructure destruction and environmental degradation following flood events in 2021.

Jointly funded by the Australian and NSW governments, the feasibility study identified cost-effective recycling solutions; statewide estuary clean-up events to recover lost infrastructure and debris; and trials of recycling options for oyster gear and shells.
