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.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Regenerative economyMarine EnvironmentBest Available TechniquesMaterial and Energy Flow AnalysisPlastics330801 Control de la contaminación atmosférica330302 Economía químicadoctoral thesisopen access
