Development of an impurity-tolerant Multi-purpose rotary tubular reactor technology MTR; sub-project: Development pilot plant scale

The planned project aims to make material flows usable for anaerobic digestion, that are currently unused due to impurities, heterogeny origin, decentralised generation and heterogeneity. Heterogeneity here refers to the fact, that different sub-fractions can only be combined into a homogeneous fermentation substrate with procedural effort, which is not economically feasible for decentralised production/smaller plants. For this purpose, an impurity-tolerant multi-purpose/variable feedstock drum reactor technology - MTR - is to be developed and intensively tested up to a TRL of 5, and the technical planning for achieving a TRL of 6-7 will be developed. This allows the realization of TRL 6-7. in a follow-up project on this basis. In this way, a considerable biogas potential with a particularly high climate protection effect and without material flow competition is to be tapped, which is available for flexible, reliable cross-sector energy supply. The development of the technology will primarily utilise organic municipal waste, which is often rich in impurities, as well as heterogeneous agricultural residues, including those with impurities. Firstly, the intensive testing and comparison of variants of relevant components should create reliable conditions for the further development of TRL 6 to 7 in a follow-up project. Secondly, in two intensive test phases for the relevant material flows, the areas of application as main or pre-digesters will be tested in order to be able to orientate the subsequent further development to TRL 6 to 7 towards the market segments and areas of application to be prioritised first. Finally, the economic and ecological effects will be assessed and the national and international market options will be determined.
