Gaseous emissions from the storage of untreated slurries and the fractions obtained after mechanical separation

A laboratory-scale study was set up to investigate ammonia (NH 3), nitrous oxide (N 2O), carbon dioxide (CO 2) and methane (CH 4) emissions during storage of untreated pig and cattle slurry and the fractions (solid and liquid) obtained by mechanical separation. The solid and liquid fractions were ob...

Description
Summary:A laboratory-scale study was set up to investigate ammonia (NH 3), nitrous oxide (N 2O), carbon dioxide (CO 2) and methane (CH 4) emissions during storage of untreated pig and cattle slurry and the fractions (solid and liquid) obtained by mechanical separation. The solid and liquid fractions were obtained from the same untreated slurry by means of a lab-scale mechanical separator. The manures were stored for a period of 30 days in open vessels (1500 cm 3 capacity) in two temperature-controlled rooms, which were kept at 5±0.5 and 25±0.2 °C. Gaseous emissions were determined using a dynamic chamber method and infrared photoacoustic detection (IPD). Over the storage period, gaseous emissions from pig manures were significantly ( P
