Environmental Dairy Design for 2020 (EDD20): Ontwerpen voor huisvestingssystemen van melkvee met lage ammoniakemissie

The objective of the (public-private partnership) Environmental Dairy Design for 2020project was to reduce ammonia emissions in dairy farming systems under 3 kilograms per animal place per year. This research shows that, in theory, it is possible to achieve this ambition through a combination of innovative solutions. However, current systems/practices, high required investments and market dynamics and forces form a serious obstacle for these innovations. Although an ammonia reduction of approximately 50% (compared to a standard Dutch livestock housing system) was achieved in the final experiment that was conducted, the ambitious objective of this project was not achieved. T he research project has developed valuable knowledge and, where possible, brought it to proofs of principle for de reduction of ammonia emissions from dairy farming systems while at the same time ensuring other sustainability requirements that apply in 2020.
