Manure management is a main source of methane (CH4) emissions. Mitigation options such as biogas treatment exist, but effects cannot be verified and are not accounted for in inventories.
In the project M4Models a new method to estimate CH4 emissions from manure is used to investigate farm-level greenhouse gas mitigation, and for upscaling to national inventories.
One of the partners, the company Bioprocess Control (BPC), develops a new incubator to quantify CH4 production rates and volatile solids degradation. Experiments study effects of feeding, biogas treatment and storage on CH4 emissions from manure.
All partners quantify CH4 production rates in manure from pig and cattle farms (volume and temperature are studied with sensors). Results are applied to parameterise submodels of daily CH4 emission that will be used to analyse country-specific scenarios with the FarmAC model.
GHG mitigation scenarios, including C storage and N use efficiency, will be studied and the results upscaled for inventories.
