Manure management for methane mitigation - Improved inventory modelling to support policy actions

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. A new method to estimate CH4 emissions from manure will be used to investigate farm-level greenhouse gas mitigation, and for upscaling to national inventories. Partners are DE, DK (coord.), NL, SE and the company Bioprocess Control (BPC). BPC will develop a new incubator to quantify CH4 production rates and volatile solids degradation. Experiments will study effects of feeding, biogas treatment and storage on CH4 emissions from manure. All partners will quantify CH4 production rates in manure from pig and cattle farms; volume and temperature are studied with sensors. Results are used to parameterise submodels of daily CH4 emission for use in analysing country-specific scenarios with the model FarmAC. GHG mitigation scenarios, incl. C storage and N use efficiency, will be studied and the results upscaled for inventories.
