Three gas analysis systems (AwiFLEX) with laboratory automation are currently being set up for the experimental facilities of the Bauhaus Institute for Future-Oriented Infrastructure Systems (b.is) at Bauhaus University Weimar. The systems are used to investigate solid and liquid fermentation. The goal is to close resource cycles and optimise energy production. A special feature here is that research questions from both biowaste fermentation and brown and black water fermentation are carried out under one roof. This results in interesting synergies for both utilisation paths and innovative solution approaches for the future-oriented management of municipal material flows. To meet these research requirements, two existing AwiFLEX systems were converted and expanded, and a new AwiFLEX XL was installed. In addition to the expansion of all gas analysis systems with AwiLAB laboratory automation for the automatic recording of gas quality and quantity in the reactors (see article Oleofat), further control tasks were taken on. Thus, the two AwiFLEXs monitor and control six reactors and agitators each in a wet fermentation system, or twelve measuring points with twelve percolate pumps in a solids fermentation system.

The AwiFLEX XL covers measurement at twelve additional reactors and controls eight agitators and four pumps. All systems operate fully automatically and can be operated at a flexible interval or switched to manual control at any time. In addition, all systems have automatic calibration for all sensors.
