Bilan environnemental de l'utilisation de l'urine humaine comme fertilisant agricole

Abstract : We used Life Cycle Assessment to compare the environmental balance of different urino-fertilizers and mineral fertilizers for the production of soft winter wheat and grain corn, conventional or organic. The limits of the system cover from the harvest of the urine to the production of one kilogram of grain at the farm gate. We have analysed the impacts of the use of urino-fertilizers on environmental impacts climate change, fine particle emissions, acidification, depletion of mineral, fossil, renewable and water resources, eutrophication and cumulative energy demand. Analyses have shown that stored urine contributes least to climate change, but is sensitive to transport distances. Concentrated nitrified urine is the least impacting urine in the categories studied, and dehydrated alkaline urine is a highly impacting urino-fertilizer in the impact categories related to ammonia emission and energy consumption. The baseline scenarios are most often advantageous with respect to the use of alkaline dehydrated urine. The gains at the treatment plant favour the conventional system more than the organic one and offer encouraging results for wastewater recovery in Ile-de-France agriculture.
