Subject and aim

The fermentation of municipal biowaste can make a significant qualitative contribution to the reduction of greenhouse gas emissions. The expansion has come to a halt at the municipal level, exact reasons are hardly known. These are to be identified systematically in the "Bio-DYN" project.
The key concern of Bio-DYN is the systematical identification and analysis of obstacles, experiences and success factors with the fermentation of municipal biowaste in connection with an acceptance-encouraging communication strategy for the dynamic progress of the expansion process. This is done by means of a systematical comparison of the obstacles for (so far) unimplemented plant projects with the experience of implemented projects and their operation. An additional focus of this practical study lies on the reluctant flexibilisation of plant operation. Clearly defined media will spread the results in the political sector (federal, state and municipal level) as well as industry (engineers, plant manufacturers and operators) and contribute significantly to a realistic evaluation of the projects for the fermentation of municipal biowaste.
