This paper presents a model project where cultural landscape management and the production of “green” energy are combined to an integrated project on sustainable regional development. The project is based on a newly developed, small-scaled and mobile biomass-system, the 3A-biogas®-technology. 3A-biogas® uses a three-step composting-process to generate methane for the production of electric and thermal energy. The advantages compared to well known systems refer to a) low energy density required for the manipulated biogenic materials, b) a small and mobile plant, which generates low investment costs and c) possibility to combine biogenic waste, lop and hay of heterogeneous quality. These characteristics make the technology highly suitable for adoption in landscape-management of less-favoured rural regions. The focus of the paper is set on the process of creating a regional programme interlinking landscape-, waste and energy management based on implementation of the 3A-biogas®-technology. Therefore, two scopes are highlighted: cross-links between landscape-planning, energy- and composting-technology in the field of engineering are sketched in the first part of the paper. The 3A-biogas®-technology is briefly introduced, followed by an overview on how the technology is “translated” to fit the questions of regional landscape-, waste- and energy management. In the concluding section some important questions on calculation of costs for landscape management based on 3A-biogas® are discussed, regarding the experiences from our pilot study.
