| A study was set up to investigate the environmental effects of anaerobic digestion and separa-tion of slurry. Volatilisation of odour and ammonia from treated and untreated slurry were compared both during storage and following land application. It was found that ammonia volatilisation was higher from uncovered stores of anaerobically digested and separated slurry than from untreated slurry, however, when slurry stores were covered efficiently, the loss rate was low and equal for treated and untreated slurry. Ammonia volatilisation following land application was found to be lower from both anaerobically digested and separated slurry compared to untreated slurry. Treatment of slurry by anaerobic digestion and separation did not reduce odour nuisances during... |

| Risikoen for ammoniaktab under lagring er højere for bioforgasset og separeret gylle, men effektiv overdækning af gyllelagre begrænser effektivt tabet. Med et effektivt flydelag er tabet ens for behandlet og ubehandlet gylle. Bioforgasning og separering af gylle begrænser ammoniaktabet i forbindelse med gyllens udbringning, effekten er højst af separering. Bioforgasning og separering af gylle fører ikke til mærkbar begrænsning af lugtgener fra gyllelagre, lugtgenerne kan dog effektivt begrænses ved effektiv overdækning af lagre. Lugtgenerne i forbindelse med udbringning af gylle er lavere ved udbringning af bioforgasset og separeret gylle end ved udbringning af ubehandlet gylle. Bioforgasset gylle og separeret gylle giver en højere kvælstofudnyttelse end... |
