From waste to resource: A systems dynamics and stakeholder analysis of phosphorus recycling from municipal wastewater in Europe

Nedelciu, Claudiu; Ragnarsdottir, Kristin Vala; Stjernquist, Ingrid (Springer Science and Business Media LLC, 2018-09-14)

Recycling Phosphorus (P) from urban wastewater can secure part of domestic agricultural P supply and contribute to a circular P supply chain. In this paper, we use literature review, stakeholder interviews and analysis, and systems dynamics for the ...
Global phosphorus supply chain dynamics: Assessing regional impact to 2050

Nedelciu, Claudiu; Ragnarsdottir, Kristin Vala; Schlyter, Peter; Stjernquist, Ingrid (Elsevier BV, 2020-09)

Phosphorus (P) availability is essential for global food security. A system dynamics model running from 1961 to 2050 was built for this study, linking global P supply to social, economic and environmental dynamics at regional level. Simulation results ...
Opening access to the black box: The need for reporting on the global phosphorus supply chain

Nedelciu, Claudiu; Ragnarsdottir, Kristin Vala; Stjernquist, Ingrid; Schellens, Marie Katharine (Springer Science and Business Media LLC, 2019-09-04)

Phosphorus (P) is an essential macronutrient in agriculture; however, lack of reporting makes its supply chain a black box. By using literature synthesis on the P challenge, we identify four areas where the reporting process is problematic: P reserves ...
