From waste to resource: Integrated CaO–Fenton treatment of digestate for nutrient recovery and hydroponic lettuce cultivation
An integrated CaO–Fenton waste-to-resource strategy was evaluated for converting anaerobic sewage digestate into a microbiologically safe and nutritionally functional solution for hydroponic lettuce (Lactuca sativa L.) cultivation. Lime stabilization at dosages up to 35% achieved near-complete pathogen inactivation. Be...
