Abstract
Management of faecal sludge poses a major challenge in Côte d’Ivoire, where on-site sanitation systems are predominant. However, this sludge represents a potential energy resource through the production of biogas or solid fuels. This paper analyzes the energy recovery potential of faecal sludge based on data from Faecal Sludge Treatment Plants (FSTPs). The results show a growing production of sludge, with a current treatment capacity of 678 m³/day and a projected potential exceeding 1,700 m³/day. Despite this potential, energy recovery remains marginal. The identified constraints are technical, institutional, and economic. The study highlights the need to integrate these resources within a circular bioeconomy framework.
