Results only available in German.


In Germany, organic and green waste from private households is collected separately and mainly utilised in composting plants (~80–90 %). Additionally, the energetic potential of this biomass can be exploited through fermentation. Regarding the lack of reasonable heat sinks at typical organic waste treatment sites, the processing of biogas and its supply into the grid is highly significant.


The project aims at developing a feasibility study on the utilisation of biogenic wastes in terms of material, ecological and energetic use – with regard to waste management structures, economy and available processing technologies and the supply of biogas into the grid. The study focuses biomass according to EEG 2012 §27a. In an overall study inhibiting factors in terms of structure, economy and acceptance are summarized and appropriate measures and recommendations are developed. The results emphasise the energetic potential of biomethane from organic waste for local players, such as plant operators, disposal companies or local politicians. Particularly the issued checklists and handouts should enable the relevant stakeholders to transfer models to real projects.



  • Elaborating the specific need of technical adaptation of the existing gas cleaning with regard to the processing of biogas from biowaste
  • Developing cost and revenue structures/profitability analysis
  • Describing and assessing the effects on resources and climate change


Determining the conditions with regard to the plant configuration and material flows for the supply of biogas:

  • Presenting the status quo
  • Identifying suitable biowaste treatment plants
  • Evaluating these plants and the regional waste flows and their availability
  • Characterising the revenue structures of biowaste disposal (composting/fermentation)
  • Analysing barriers and developing action-oriented measures
  • Plant-related technical measures
  • Organisational and structural measures
  • Information and motivation measures for acceptance


  • Identifying implementation barriers (structural, regional-spatial, economical, technical, political)
  • Analysing stakeholder-related  acceptance at municipal level
  • Focusing acceptance and  the perspective of the stakeholders
  • Perceiving and assessing technical consequences (positive as well as negative effects)
