The EmiMod investigates emissions from naturally ventilated cattle and pig barns, focusing on climate-relevant gases, odors, and bioaerosols. The aim is to simplify the sometimes extremely complex methods for recording and evaluating emissions and immissions, enabling more cost-effective results without compromising accuracy and precision. EmiMod combines standard measurement methods with new, cost-effective sensor solutions and uses modeling and AI methods for emission and immission forecasting.
As part of this year's meeting, a visit was made to the Lower Saxony Chamber of Agriculture's pig farming research station in Wehnen. Numerous measurements related to EmiMod ; the Thünen Institute, the Federal Institute for Occupational Safety and Health, the Universities of Bonn, Hohenheim, and Kiel, LUFA-Nordwest, LFL Bayern, and the Leibniz Institute for Agricultural Engineering and Bioeconomy are involved. The investigations focus on measuring temperature, humidity, wind direction, and particulate matter using new sensor technologies; collecting air samples for bioaerosol analysis; applying new technologies to determine odor emissions (sensors and ion mobility spectrometry); conducting emission studies based on simplified tracer gas measurements; and training an AI for automated animal observation using RGB and infrared video recordings.
The EmiMod is scheduled to run until 2028. In 2026, a physical meeting will take place at the University of Bonn, along with a visit to the TUI dairy barn at Haus Riswick, which opened in 2024 and where further research on EmiMod will be conducted.
