Greenhouse Gas Emission from NAP-Covered Earthen Manure Storage Basin
The agriculture sector contributes to Canada’s greenhouse gas emissions, with livestock operations and manure storage having a large part. A negative air pressure (NAP) cover may help reduce greenhouse gas emissions from earthen storage basins. The NAP-cover had a minor improvement on greenhouse gas emissions compared to the straw-covered surface, but odour emissions were greatly reduced. The NAP-cover may have further benefits if added biofilters at exhaust fans are added.
