This study presents results from lab‐scale studies and highlights issues related to process monitoring equipment and analytical methods at the field scale. This includes the evaluation of data from on‐site online sensors and sample analyses as well as results from discontinuous and continuous digestion tests in a biogas laboratory. The results demonstrate the influence of the organic loading and wastewater composition on process stability, sludge activity, and biogas production. Key recommendations for plant operation include the avoidance of strong fluctuations in input volume and concentration, to ensure good functioning of online sensors, and to adapt the management of the different wastewater streams according to their characteristics.
