In the perspective of exploiting the economic opportunities for the recovery and reuse of waste as resources, our study aims to promote sanitation and improve agricultural productivity. It was assessed by collecting urine from households and drinking establishments in Katiola city, Toumbokaha and Kassémé villages and its use as a fertilizer. A total of 25 drinking alcohol operators and 258 households have agreed to install urine production equipment. They provided about 2.500 and 32.000 liters of urine per month. Studies have shown that wastewater facilities installed in households are more effective in providing urine through their frequent and regular use. Thus, households are more efficient in providing urine (more than 12 times) than public places. This means that individual sanitation is more effective than collective sanitation. These collected urines are hygienized by storage and applied as fertilizer to rice fields. The yields of urine fertilization are higher than those of chemical fertilizer fertilization, with the added benefits of herbicide. While improving rice productivity and thus soil fertility, urine ensures the sustainability of rice-based systems at economically bearable costs by producers. These results are an expression of the accession of the populations, a guarantee of the sustainability of the EcoSan approach, through their involvement in the production, collection and use of urine as fertilizer.

Abstract: (french)
Dans la perspective d’exploitation des opportunités économiques de récupération et de réutilisation des déchets comme ressources, notre étude s’est fixée pour objectif de faire la promotion de l’assainissement et d’améliorer la productivité agricole. Elle a été évaluée à partir de la collecte de l’urine auprès des ménages et débits de boisson de la ville de Katiola, des villages Toumbokaha et Kassémé ainsi son utilisation comme fertilisant. Au total 25 tenanciers de débits de boisson et 258 ménages ont accepté l’installation des équipements de production d’urine. Ils ont fourni respectivement environ 2 500 et 32 000 litres d’urine par mois. Ainsi les ménages ont été plus efficaces dans la production d’urine (12 fois plus) que les lieux publics. C’est dire donc que l’assainissement individuel est plus efficace que l’assainissement collectif. Ces urines collectées sont hygiénisées par stockage et appliquées comme fertilisant sur les sites rizicoles. Les rendements de la fertilisation à l’urine sont meilleurs à ceux de la fertilisation à l’engrais chimique avec en plus des avantages liés à son caractère herbicide. Tout en améliorant la productivité du riz et donc la fertilité des sols, l’urine permet d’assurer la durabilité des systèmes rizicoles à des coûts économiquement supportables par les producteurs. Ces résultats constituent l’expression de l’adhésion des populations, gage de la durabilité de l’approche EcoSan, à travers leur implication à la production, la collecte et utilisation des urines comme fertilisant.
