My PhD project is part of the NFR project SLAM-DUNK (RCN Project number: 326861). The main aim of SLAM-DUNK is to design, optimize, and integrate a combination of novel technologies (anaerobic digestion, microwave assisted pyrolysis, and microalgae cultivation) for the conversion of fish sludge to valuable products. The PhD project is focusing on the optimization of microalgae cultivation on residual streams from aquaculture directly and from digester liquid from an anaerobic digestion (AD) process. My project is as well going to evaluate the potential of the mentioned value chain regarding logistics performance and sustainability. How sustainable are the proposed value chains from fish sludge collection until product use with respect to life cycle impact, energetic viability and economic status? We will study this using a combination of mass flow analysis, logistic analysis, life cycle assessment, energetic/exergetic analysis and optimization, as well as a techno-economic analysis.
