AGROCAPI restitution symposium

The AGROCAPI research project has studied during four years human urine source separation methods and the pathways toward an agricultural use of urine-derived fertilizer. It was initiated in France by the LEESU (Ecole des Ponts) and ECOSYS (Inrae) laboratories. The results of AGROCAPI were shared at a closing symposium in Paris and online in January 2022.

Four presentation sessions were organized: the morning was devoted to the presentation of works on the (re)discovery of urino-fertilizers, before addressing the various topics of vigilance regarding their use today. The afternoon was devoted to the construction of new value chains, and the question of mutualism between sanitation and agricultural production.

All the presentations can be viewed in replay.

Practical sheets were produced on this occasion, entitled : “Using human urine in agriculture” (in French).

Agrocapi food productions of were also proposed for tasting (Biscodor [Gold biscuits] cookies produced from wheat flour grown in the Paris region, on experimental plots fertilized with human urine.)

Finally, the Ministry of Agriculture has committed to setting up a national working group to facilitate the emergence of human urine value chains.
