This research project
aimed at quantifying GHG and NH3 emissions froma
commercial straw flow system for fattening pigs, and
from the subsequent storage of the pig slurry. It was found that that a solid cover was effective in
mitigating gaseous emissions from pig slurry during
storage. Emission levels differed when slurry was stored
under warm and under cold climatic conditions. It is
therefore suggested to set up the national emission
inventory by applying separate emission factors for slurry
storage in the colder and in the warmer half of the year.
