THI Presents Biogas Research at the EUBCE in Valencia
THI Researcher Presents Innovative Biogas Methodology at the European Biomass Conference in Valencia
From June 9 to 12, 2025, the 33rd European Biomass Conference and Exhibition (EUBCE) took place in Valencia, Spain. As one of the world’s leading events for experts from science, industry, and policy, the conference once again served as a key platform for international exchange on topics such as sustainable energy generation, biofuels, conversion technologies, and the circular economy.
THI researcher presents innovative biogas methodology
Among the participants was Joshua Ngetuny from the Industrial Energy Systems research group at the Institute of New Energy Systems (InES), Technische Hochschule Ingolstadt (THI). He presented his study titled “Biogas in the Developing World: Feedstock Availability and Selection Using Analytic Hierarchy Process.”
New methodology for selecting and prioritizing biogas feedstocks
In his presentation, Ngetuny introduced a novel methodology for selecting and prioritizing feedstocks for small-scale biogas plants. The approach aims to improve the resilience and sustainability of such systems, particularly in developing regions. The method evaluates potential feedstocks based on three key criteria: feedstock suitability, supply consistency, and logistical feasibility.
Research findings: Supply consistency as the key stability factor
Results from the research showed that supply consistency has the strongest impact on the stability of biogas plants, followed by suitability and logistical aspects. Using a case study in the Fès-Meknès region of Morocco, potential feedstocks identified through farm surveys were analyzed and ranked. Cattle manure emerged as the top feedstock due to its steady availability, ease of handling, and good digestibility. It was followed by straw from wheat, maize, and barley, which stood out for its storability and consistent supply. Other materials such as sheep, horse, and chicken manure ranked lower.
Based on these findings, the study recommends co-digestion of cattle manure and straw, as the combination offers a balanced nutrient profile and enhances process stability.
Embedded in the international AMBER research project
The research was conducted under the supervision of Prof. Wilfried Zörner as part of the international AMBER project, which focuses on sustainable biogas systems and renewable energy strategies in different regions worldwide.
Importance for biogas research and international collaboration
Participation in the EUBCE highlights InES’s strong commitment to applied research that promotes sustainable biogas technologies. By presenting at one of Europe’s most prestigious biomass conferences, InES was able to share its latest findings with an international audience and gather valuable input for future collaborations.
