The experiment was done in a 52 L batch reactor. The emissions rates measured varied for ammonia from 400 to 970 g NH3-N/m3, for methane from 0,6 to 385 g CH4/m3 and for nitrous oxide from 1,9 to 71,9 g N2O-N/m3. No information is given on the C/N ratio of the mix used for composting (mature compost, saw dust and manure). No statistical analysis is presented to explain the emissions variations and the aeration treatments.
