Environmental sustainability opportunity and socio-economic cost analyses of phosphorus recovery from sewage sludge.

ABSTRACT: Although phosphorus (P) recovery and management from sewage sludge are practiced in North America and Europe, such practices are not yet to be implemented in China. Here, we evaluated the environmental sustainability opportunity and socio-economic costs of recovering P from sewage sludge by replacing the current-day treatments (CT; sludge treatment and landfill) and P chemical fertilizer application (CF) in China using life cycle assessment and life cycle costing methods. Three potential P recovery scenarios (PR₁‒PR₃: struvite, vivianite, and treated sludge) and corresponding current-day scenarios (CT₁‒CT₃ and CF) were considered. Results indicated that PR₁ and PR₂ have smaller environmental impacts than the current-day scen
