Abstract: Wastewater rich in carbon can be processed by microorganisms to obtain a biodegradable polyester, polyhydroxyalkanoate (PHA). However, the mechanical properties of this polymer make it unsuitable as polymeric material. Moreover, processing of PHA is challenging. To circumvent these issues, a conversion of the inferior PHA to methyl acrylate and propylene is proposed which can be used in current processing infrastructure.

Abstract: There are many changes in marine ecology taking place in European seas. This thesis contributes to the need to understand the economic implications of these changes and to formulate management strategies. To do so, the thesis is divided into two parts which consider marine ecological change within two distinct sub-topics. Firstly, in Part A, this thesis focuses on economic analysis of marine invasive species. Invasive species are taxa that have been introduced outside of their native range (IUCN, 2000). These introduced taxa may then be detrimental to economic output and lead to biodiversity loss and reduced ecological services (Frésard and Boncoeur, 2006). Secondly, Part B concerns International Fisheries Agreements (IFAs). IFAs aim to ensure profitable and sustainable fishing when multiple countries have an interest in a given fish stock (Hilborn et al., 2005). Part B focuses on the impacts of changing fish stock location and possible fish stock collapse on the success of IFAs. The topics in Parts A and B represent important contemporary concerns in Europe, as reflected by the focus on these topics within the EU Seventh Framework Program project named VECTORS (www.marine-vectors.eu), to which the research in this thesis has contributed.
