Technical pathway to the sustainabilyty of our seas to facilitate a regenerative worldresources and waste, food and enjoyment

Resumen

This thesis analyses human activities around the sea using a life cycle approach for the identification of sustainable techniques to facilitate the path towards a regenerative economy. The first part deals with the sector of fish and seafood industry, the second part deals with activities related to the fishing sector, and the third analyses activities in the marine environment as a place of enjoyment. Material and energy flow analyses allows to identify impacts of resources and wastes, and Best Available Techniques are proposed. Chapter 9 is dedicated to plastics in the sea related to all the previous activities, including dynamic analysis of flows and stocks, through modelling that predicts trends in the behaviour of these compounds.
