Recently, promising initial results from the EIP-AGRI project SaLu_T were published in an international scientific journal. The publication, titled "Assessment of Odour and Ammonia Impacts for a Novel Fattening Piggery Tailored for Animal Welfare and Low Emission Rates," can be found in the journal *atmosphere*.
Under the direction of Dietmar Öttl (Office of the Styrian Provincial Government, Department 15) and with the collaboration of colleagues from the HBLFA Raumberg-Gumpenstein, promising initial results from the EIP-AGRI project "Clean Air in Animal Production: Emission Reduction and Animal Welfare in Pig Fattening" (SaLu_T) were recently published in a renowned journal. The article " Assessment of Odour and Ammonia Impacts for a Novel Fattening Piggery Tailored for Animal Welfare and Low Emission Rates," published in Atmosphere 2023, 14, 75, presents the highly positive results regarding odor and ammonia emissions from the investigated animal welfare housing system.
The resulting odor emission factor is approximately 8 LU/LU/s (odor units per livestock unit per second), which is almost 95% lower than the baseline factor of 140 LU/LU/s for fattening pigs in report no. Lu-01-2021 (Odor emissions from livestock farming, ABT 15 - Air Pollution Control). For ammonia, an average emission factor of 0.73 kg/TP/a (kilograms per animal place per year) was determined. Compared to the baseline factor of VDI 3894-1 of 3.64 kg/TP/a, the current investigations show a factor that is approximately 80% lower. Reference is also made in this context to the report (https://www.umwelt.steiermark.at/cms/beitrag/12889493/19222537/) by the Styrian Environmental Protection Agency.
