Berekeningen over emissies, massabalansen en economie bij gezamenlijke monomestvergisting: Scenariostudie voor energiecoöperatie Wijnjewoude

This study focuses on model-based calculations of various manure processing scenarios for the Energy Cooperative in Wijnjewouden. The study concerns the possibility of teamwise mono-manure fermentation of 26 dairy farms and the effect on the reduction of ammonia and greenhouse gas emissions was examined. If slurry is removed daily from the cattle barn, fermented after a short storage time and the digestate is stripped, an ammonia emission reduction of 46% can be achieved over the entire chain, as well as a greenhouse gas emission reduction of 78% (enteric emissions excluded). However, this is highly dependent on the chosen low-emission housing system and how quickly liquid manure is removed from the barn and further processed. Furthermore, assuming that RENURE fertilizers may be used as fertilizer, a saving of 160 tons artificial fertilizer per year can be achieved (equal to approximately € 700,000) and with the central fermentation of manure and upgrading to green gas an equivalent of 1,786 tons of CO2 emissions can be prevented.
