Abstract: The integration of agriculture and aquaculture with anaerobic digestion is a popular practice at small Asian farms as a way of producing energy and fish, i.e. providing a better nutrient balance and resource recycling. Concerns are raised whether the resource efficiency of such system is better or worse relative to the monoculture system. In this study, we focused on quantifying the resource demand of two integrated Pig–Biogas–Fish farms in Vietnam. The analysis was performed by using the exergy concept: exergy flow analysis (ExFA) at process level and Cumulative Exergy Extraction from Natural Environment (CEENE) at life cycle level.
