The development of a bio-based economy is a top priority for the future research and technology promotion in Europe, and a research focus area for Aarhus University. My Ph.D. position is part of the EU-funded H2020 research project DECISIVE (DECentralIzed management Scheme for Innovative Valorization of urban biowastE). The project focuses on the development of sustainable urban organic material fluxes from a linear paradigm to a circular paradigm.


The main objective of my Ph.D. project is to investigate, at societal level, the barriers and impacts of introducing innovative waste management and bio-refinery systems and to assess their expected environmental and socio-economic impacts. A special focus of the Ph.D. is to understand the existing governance framework for organic waste in Europe, and in case-study countries, with a focus on the introduction of innovative decentralized systems. Based on the outcome of the screening, I will then explore the regulatory barriers for the introduction of emerging technology in the waste sector, and evaluate the need for alternative policy instruments, economic tools, and governance systems to support the transformation of current systems to the DECISIVE decentralized system.


The first paper models the amount of heavy metals contained within four dietary profiles as an indicator of the health and safety of existing food production systems. The second paper assesses the efficiency of the current policy/regulative framework in limiting the heavy metals accumulation in our food and food waste at EU, the regional and local level within the DECISIVE framework. The third paper assesses the current policy and regulatory measures and their effectiveness to enable or inhibit societal innovation processes within a DECISIVE pilot study and proposes alternative regulatory measures or policy tools. Paper four measures and compares the sustainability performances of local bio-based production systems vs the centralized bio-based production systems considering the socio-economic and environmental benefits and costs.
