Burkina Faso has extensive experience with urine-diverting dry toilets (UDDTs) and the reuse of human excreta in agriculture in line with the ecological sanitation (ecosan) principles of containment, treatment, and reuse. Around 30 such ecosan projects have been implemented over the past 15 years, including installation of approximately 13,500 household UDDTs, accompanied by awareness-building and training on toilet use, emptying, and reuse. Recently, efforts have been made to revisit former and current project sites in the spirit of ‘return to learn’. We identified four such learning initiatives (studies/events), from which we draw recommendations to improve the sustainability of future implementation of ecosan in Burkina Faso and similar contexts. Key recommendations include increased attention to different user needs, handwashing and training on emptying/reuse as well as research and innovation on toilet design, urine collection/handling, menstrual management, and cost reduction/financing. Burkina Faso has set up the ambitious goal of 100 per cent toilet coverage and optimal reuse in the national sanitation programme by 2030, with UDDTs projected to make up 15 per cent of the 2 million toilets needed in rural areas. It is therefore timely to take stock and learn from past interventions. In addition, to enable resource recovery and reuse at scale, it will be important to develop a supportive policy and legal framework with collaboration between the WASH, agriculture, health, and environmental sectors.
