- •
A new modeling approach to calculate GHG and NH3 emissions from anaerobic digestion processes is proposed.
- •
The new model is used to simulate C and N flows and GHG emissions for a set of scenarios exploring different conditions.
- •
Post-digestion emissions and its relationship with the anaerobic digestion performance are the main factors affecting net GHG emissions.
- •
Gas tight digestate storage is recommended as well as operational conditions enhancing the process efficiency.
- •
Potential for GHG mitigation through manure anaerobic digestion is higher in warmer regions, where it should be promoted.
- •
The model can be integrated in holistic approaches to develop adequate mitigation strategies in the agricultural sector.
