Life Cycle Assessment (LCA) of Two Different Oyster (Crassostrea gigas) Farming Strategies in the Sacca di Goro, Northern Adriatic Sea, Italy

The Pacific oyster Crassostrea gigas is one of the world’s most cultivated and prized molluscs. Although it usually considered a luxury product, meets all requirements to be included in sustainable diet, its production consumption have great potential for growth coming years. Oyster farming worldwide activity, with China France as main producers, but recently, possibility implementing Italian production, mainly focused on clams mussels, has been an interesting issue, especially due growing local global demand. present study carried out by collecting data from Sacca di Goro, north-east Italy, important national mollusc area. Life cycle assessment (LCA) methodology was applied two different scenarios order improve overall sustainability process. Using OpenLCA™ software (GreenDelta, Berlin, Germany) ReCiPe® midpoint (H) v.1.12 method, environmental impacts traditional technique, entirely offshore longlines, alternative option, which seed pre-fattening phase lagoon, were calculated compared. results show that replacing current lagoon reduces CO2 emissions approximately 12% other impact categories 9%. In addition, non-recyclable plastic materials fuel emerged hotspots.
