| Abstract | The sustainable and continued production of enough food to feed the entire world's population is one of the main concerns in the food industry. Spain, and in particular Galicia, which is an eminently fishing region characterised by the consumption of large quantities of fish, both fresh and processed, must face the challenge of shifting its seafood productive fabric towards a circular economy. To achieve this objective, the first task is to demonstrate that circular economy principles allow to reduce the environmental impacts associated with seafood production. In this sense, this study proposes the environmental evaluation of the skipjack tuna (Katsuwonus pelamis) value chain within a canning industry located in Galicia through the LCA methodology from an attributional perspective, including the valorisation processes for biowaste (edible and inedible by-products). Results indicate that the main crucial subsystems of the value chain are tuna fishing and the canning process, as it was expected considering other similar studies on seafood products. Moreover, this specific case study demonstrates that the multi-product strategy applied to the canning sector is environmentally viable. Thus, although the environmental impacts of the entire system are increased by including further valorisation operations, the environmental loads assigned to the main product (canned tuna) decrease compared to the one-product system by assigning environmental burdens to other value-added products (tuna pate, fishmeal, and fish oil).
