Resource usage of integrated Pig-Biogas-Fish system: Partitioning and substitution within attributional life cycle assessment

Improvements could be achieved through a better water management in aquaculture and an increased biogas utilization, preventing any leakages. Fertilizing the fish pond with manure-based digestate instead of fresh manure and/or rising the application rate might be a more efficient way to reduce pelleted fish feed consumption, although further research on such options are needed.
