In the Netherlands, measures for mitigation of Particulate Matter (PM) emissions are needed for poultry houses to lower their contribution to elevated ambient PM concentrations. In this study, we 1) investigated whether on-farm drying systems (DS) for poultry manure can remove PM from the exhaust air flow, and 2) evaluated the contribution of DS to ammonia emissions. At two layer facilities, a total of twelve 24-hour measurements were carried out of temperature, relative humidity, ventilation rate, PM and ammonia between December 2009 and February 2010. A substantial removal of inhalable dust (69% for house 1), PM10 (83% for house 1; 33% for house 2) and PM2.5 (57% for house 1; 32% for house 2) was found. Concentrations of ammonia however, increased by a factor 5.0 (house 1) and 3.6 (house 2) over the manure layer. This study shows that DS for poultry manure show good ability to remove PM, but further research is necessary to avoid problem swapping by elevating emissions of other pollutants.
