By means of the bioliq® process at Karlsruhe Institute of Technology, flash‐pyrolyzed straw is converted into slurries made of pyrolysis condensates and char. These slurries can be gasified to produce syngas and, subsequently, synthetic fuels and chemicals. Investigations show that a stable slurry of the pyrolysis products is not miscible, as the condensates tend to split into organic and an aqueous phases. Thus, application of two different slurries is suggested: The organic condensates can be gasified directly, and the aqueous condensates can be mixed with 40 wt % ground straw char. This latter slurry is the focus of this work, which describes the mixing, settling, and stirring behavior. Grinding the porous and elongated char particles decelerates sedimentation and also decreases the viscosity. Thus, higher‐concentrated slurries can be mixed, which leads to higher stability.

The qualitative results of this empirical thesis are the four superior challenges “reduced time for development”, “integration of the value chain”, “reduction of complexity” and “digital transformation”, which apply to the product development of wind turbines. It is assumed that these superior challenges apply to a variety of business areas rather than only for the product development. Recommendations for actions to reduce the time for development are “customized integration of agile approaches”, “break down silo mentality” and “optimization of the innovation culture”. For the integration of the value chain in the product development process, an “establishment of a common basis of trust”, “establishment of multi-company development networks” and an “increase of compatibility of different tools and process automation” are recommended. A reduction of complexity can be achieved with an “expansion of the available capacities in predevelopment” and “development of long-term multi-platform strategies”. The challenges and possible solution approaches for “digital transformation” need further investigation, but it is clear to advise to “ensure access to operational data through digital business models or service contracts”.
