Norwegian Church Aid (NCA) invites Expression of Interest (EoI) from a dynamic local Small or Medium Enterprise (SME) interested in developing a business in Fecal Sludge Management (FSM) in Maiduguri - Borno and Shani & Gashua - Yobe States. The aim is to turn Fecal Sludge Management into a profitable business opportunity. The selected enterprise will operate existing treatment infrastructures, belonging to State Environmental Agencies (BOSEPA, YOSEPA), to recycle treated sludge into valuable products such as bio-fertilizers and briquettes, contributing to environmental protection and promoting a circular economy model.
