This study assessed the change in the environmental impact of producing and using the end products, including mineral concentrate, from several pilot facilities as mineral fertilizer and substrate for anaerobic digestion. The LCA methodology was applied to assess the environmental consequences of four pig and dairy cattle slurry scenario’s. The scenarios were compared to a reference. Results showed that no mineral fertilizer was replaced in the scenarios. Without anaerobic digestion, no change in the environmental performance was observed for fattening pig slurry. Digestion reduced greenhouse gas emissions and fossil energy use. The sensitivity analysis showed higher ammonia and particulate matter emissions in all scenarios when processing more manure than only a surplus.
