Closing the nutrient loop between urban and rural areas: a case study analyzing the technical potential of recycling fertilizers from urban biorefineries

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The world's population is expected to grow rapidly, with the vast majority of people living in urban areas. Closing nutrient loops is therefore increasingly important for food security and environmental stability. In Germany however, the current treatment of organic and green waste and sewage sludge (derived from wastewater) includes ...
