Pretreatment in Small-scale Biogas Systems: A pathway to Mainstreaming Co-digestion and Agricultural Residue Utilization
Short Introductive summary
This study presents a methodological framework for prioritizing and selecting suitable pretreatment methods as a pathway to mainstreaming co-digestion in small-scale biogas systems, thereby improving their resilience and operational sustainability through the utilization of previously neglected agricultural residues. The Analytic Hierarchy Process (AHP) methodology is employed to prioritize potential pretreatment methods using a set of evaluation criteria. These criteria are designed to ensure that the chosen process is affordable and accessible for small-scale biogas plant adopters, considering their economic and technical realities. Finally, it concludes with a recommendation of a practical implementation framework of the method or combination of methods most suited for implementation in small-scale biogas systems in developing countries. Successful implementation of this pretreatment strategy has the potential to improve the reputation of biogas technologies as dependable energy and circular economy contributors in these countries and regions.
