Potential nutrient conversion using nature-based solutions in cities and utilization concepts to create circular urban food systems

23 Jul 2021

This paper quantifies the potential nutrients (main plant macronutrients nitrogen, phosphorus, potassium) that could be recovered from urban wastewater and biodegradable kitchen waste using nature-based treatment solutions. Results indicate that, using NBS, the wastewater and kitchen waste from 77,250 persons could fully cover the nitrogen and phosphorus fertilizer demand of the entire vegetable production in Vienna, which currently supplies one-third of Vienna’s vegetable consumption. Additional people connected to the system can supply significant excess nutrients to produce other crops within and beyond the city.
