A German-Brazilian research project investigates sugarcane as an energy plant in anaerobic digestion for biogas production. The aim of the project is a continuous, efficient, and stable biogas process with sugarcane as the substrate. Tests are carried out in a fermenter with a volume of 10 l. In...

To fully model the anaerobic digestion process, biological and physico-chemical background, the kinetics of bacterial growth, substrate degradation and product formation have to be taken into account. The presented approaches differ depending on the requirements and the developer of the model....

The objective of this study was to characterise anaerobic batch biodegradation of potato waste alone and when co-digested with sugar beet leaves. The effects of increasing concentration of potato waste expressed as percentage of total solids (TS) and the initial inoculum-to-substrate ratio (ISR)...

The treatment and disposal of excess sludge represents a problem of growing importance of wastewater treatment plants all over the world. Anaerobic digestion is the most common method for sludge stabilization resulting in biogas production at the same time. In the present study, in pilot-scale...

In the present study, laboratory scale biogas production from rice husks (RH) generated from different rice mills was investigated using cow rumen fluid as a source of inoculum. The effects of various parameters such as water dilution, initial pH, heavy metals and nitrogen sources on digester...

The influence of selected geometric bioreactor parameters on the performance of continuous-flow-type low-temperature biogas production from biomass by anaerobic digestion was studied to determine the optimal geometric parameters of the digester. A continuous-mode two-stage bioreactor was applied...

Determination of biochemical methane potential (BMP) by fermentation tests is time-consuming and costly, and therefore not useful for operators of full-scale biogas digesters. A great advantage of NIRS in determining BMP is the reduction in measurement time from at least one month for chemical...

Sanitation is required for biogas plants handling slaughterhouse and food waste according to EU legislation. The standard method is pasteurization at 70 °C for 60 min, but integrated thermophilic sanitation (ITS), requiring 52 °C for 10 h in the digester, has been approved by the Swedish...
