Project description

In the Flemish agricultural sector, there is a nutrient surplus of animal source on the one hand, while on the other hand additional nutrients are supplied in the form of artificial fertilizer. Stripping-scrubbing is a technology that makes it possible to upgrade nutrients from manure to ammonium salts. However, these fertilisers are not yet applied in practice, as they are considered as animal manure and must therefore comply with the Nitrates Directive. In 2020, the EC published the report SafeManure, which concluded that ammonium salts were allowed to be applied as "RENURE" (REcoverd Nitrogen from manURE), on the basis of several criteria in addition to the Nitrates Directive.

Since ammonium salts emerged from this study as a priority, the RENURE operational group wants to prepare the agricultural and horticultural sector for the use of these fertilisers by making the transition from research-based field trials to a practical evaluation at the farmer's premises. This will help to share acquired knowledge and experience on the practical application of ammonium salts, to identify possible bottlenecks and to gain insight in the impact of the RENURE criteria on Flemish agriculture. This project will ensure that the sector is prepared once the legislative framework is in place.
