Biogas systems are complex in the sense that they cut across several sectors, mainly agriculture, waste management and energy. Cooperation between actors in these sectors must work for biogas projects to be realised and successful. The aim of this report is to describe the biogas systems in Skåne from a value chain perspective, including important development pathways. The different segments in the value chain are mapped with regard to actors, actors in supporting activities, technologies and institutions (mainly regulations). Skåne is a fairly small part of Sweden in terms of land area but it is the most important agricultural and food producing region in Sweden and comparatively densely populated. These characteristics explain why Skåne is an important (if not the most important) biogas region in Sweden. The earliest applications of biogas were for the purpose of reducing the volume of sewage from waste water treatment plants. The biogas produced was used mainly for plant process needs and part of it was often flared. Much of the biogas today, from a variety of types of biogas plants, is upgraded and used for transport. The development towards transport applications can be traced back to the desire to reduce oil dependence and urban air pollution from diesel buses. Initially buses were converted to compressed natural gas, but with regional ambitions for fossil free public transport attention in recent years has turned to compressed biogas. Biogas value chains have developed in response to sustainability concerns in energy and transport, sewage sludge and waste handling, and in agriculture. The development has generated new business opportunities, especially in the field of upgrading. The production of biogas, for transport fuel, waste handling and fertiliser, is expected to continue to grow in Skåne.
