Chapter three highlights the potential of recovery and reuse nitrogen to produce waste-based fertilizer. Chapter four: The assessment of citizens and farmers in waste-based fertilizer were surveyed and the situation of emptying septage sludge and agriculture activities were determined. Chapter five: Three Sustainable and integrated waste-based nitrogen management scenarios were examined, as well as the baseline scenario, to verify the potential of recovery and reuse nitrogen from waste sludge.
