Reducing Ammonia Emissions in Pig Housing with Innovative Prototype

This project aims to address the issue of ammonia emissions in intensive pig housing by developing a prototype system that captures both ammonia and dust. By drawing air from the rooms and treating it with an ammonium sulphate solution, this system aims to reduce emissions into the atmosphere while also improving animal welfare and workers' health. The captured ammonia and dust can then be mixed with the solid fraction from slurry separation to reduce greenhouse gas emissions and increase nitrogen content for potential nutrient recovery. The expected outcomes include improved air quality in the treated rooms, quantification of avoided ammonia emissions, characterization of the captured materials for fertilizer use, and reduction in emissions from the storage of treated solid slurry fraction. Additionally, the project will evaluate the cost-effectiveness of this technology by analyzing its impact on production costs per kilogram of live pig weight.
