The flexible production of biogas makes it a promising candidate to become the first renewable, on-demand energy source. One appealing possibility to achieve an on-demand supply of methane is to adjust the output of the biogas plant itself. As a cons

Excessive foaming in anaerobic digestion occurs at many biogas plants and can cause problems including plugged gas pipes. Unfortunately, the majority of biogas plant operators are unable to identify the causes of foaming in their biogas reactor. The
