Due to global warming and severe climate change the Danish government has, in the field of energy and agriculture, stated targets of reductions in GHG-emissions and increases in the amount of animal manure used for energy production. In order to reach these targets, this study investigates how straw as a sustainable residual product can be used in optimizing the biogas production in the Zealand Region. This leads to the following research question: What conditions must be present to establish a successful straw-based biogas plant, and how can these be transferred to both a further development and planning of a plant concept in Køng/Lundby? This question is examined based on empirical data from interviews, field trips and academic articles and is inspired by the method of technological backcasting in the structural approach. The conditions are initially identified and then transferred to a case analysis of how to develop a proposal for an economically profitable plant concept in the area of Køng/Lundby. The conditions are furthermore classified and processed in technologically/geographically and planning related aspects, in order to expose the planning process up until now, elaborating on the actors involved in the project. In closing, straw-based biogas plants, as a technology, is then analyzed in a reflective, innovative perspective, to give a critical view on the development of a straw-based biogas sector in Denmark and the uncertainties related to this. The conditions are identified as being; a stable resource base, all-year distribution options, a hammer mill EUB8000 unit as a pre-treatment technology, shorter digestion time and public involvement in the planning process, and the study concludes that the operational economic proposal posits a sufficient gas yield, natural gas price and a stable resource base and price. As a proposal to optimize the planning process, this study concludes that coalition thinking can be a tool in this context. Furthermore the study suggests that the local government, Vordingborg Municipality, will take on a more central and active role as project facilitator to ensure a better structured planning of a biogas plant in Køng/Lundby.
