Slurry acidification is an efficient technology for reducing ammonia emission. In Denmark, 20 % of all slurry is acidified prior to land application. The technology is fully implemented in the Danish environmental legislation and is also admitted as a BAT technology for reducing ammonia emissions in the final draft of the BREF for the Intensive Rearing of Poultry and Pigs.
On September 28th-29th 2016 The Danish EPA facilitated an international seminar. At this event researchers, legislators, technology manufacturers etc. presented their experiences in using slurry acidification.
