Manure separation in dairy barns

The approach to emissions from stable and storage, aims to develop innovative techniques and measures in stable, manure and processing for emission reduction and to implement them in practice, so that the reduction targets are met in 2030.

The LNV research program Stable and Storage consists of Measurement and Monitoring (E) research (F), pilots and demos (G) and communication (H). Research must show which reduction techniques work and how much emission reduction this produces.

In addition to research aimed at new stables, cost-effective modifications to existing stables will also be considered. The effects of the reduction options will be tested in practice and demonstrated at pilot and demo farms.
In order to achieve implementation of reduction measures, knowledge about new and existing measures will be disseminated among the target group of livestock farmers and farmyard owners. The approach provides action perspectives for livestock farmers to reduce emissions and encourage implementation.
This research (F) will show whether a permeable tile floor under practical conditions results in a good manure separation with a reduction of NH3 and CH4 emissions.

This project proposal is closely aligned with the PPS Manure Separation in Dairy Cowsheds that started in 2019. By the end of 2019, systems of primary manure separation have been identified and described. The three most promising ones have been selected for application in existing dairy barns. Two systems will be investigated as part of this PPP starting in 2020 and one system in this project proposal as part of the climate envelope.
