| Ammonia emissions pose a threat to the climate, the environment, and health. They cause economic damage both indirectly and directly through the loss of fertilizer-effective nitrogen. However, achieving the quantitative targets for reducing ammonia emissions set out in the ‚Emissionsgesetz-Luft 2018‘ presents major challenges, particularly for the agricultural sector. The AMMORE project pursues a practical approach to using agricultural residues to sequester ammonia emissions from farm manure, a major source of emissions. After treatment, this should provide a practical time frame for low-emission application of the farm manure. At the same time, fermentative utilization of the separated ammonia is intended to produce a protein-rich feed, known as single-cell protein (SCP), thereby generating added value in the region. To achieve these goals, the suitability of two different technological concepts was investigated. The transmembrane chemisorption process proved to be superior in many respects and was therefore studied in detail on a laboratory scale. Key insights into the practical applicability of this technology were gained during the project work. The amino acid composition of the SCP was determined and its suitability as animal feed was assessed. The effectiveness and sustainability of ammonia separation was confirmed by determining its reproduction rate. Based on the data obtained in the project, an economic assessment of the overall concept for use at a sample farm was carried out. In summary, the project work successfully demonstrated the overall technical concept and discussed further R&D requirements. AMMORE made a significant contribution to the timely implementation of the developed technology in practice. |
