Abstract
Phosphorus is a key non-renewable element used in multiple economic activities, and notably for food production. It is therefore a critical material whose recovery is gaining interest. This work maps the annual phosphorus flows across Ontario's economic sectors through material flow analysis using open data sources. This information is used to identify potential opportunities for phosphorus recovery and recycling, all while performing an economic assessment to determine the feasibility of phosphorus recovery from different sectors. Up to 86% of phosphorus imports for food production could be covered by recycled phosphorus, with an average recovery cost of 49 CAD/kg of phosphorus. This cost is lower than the estimated economic losses caused by phosphorus releases into the environment, although it is significantly higher than the cost of fossil-based phosphorus products. However, phosphorus recovery costs vary widely for different waste streams, suggesting the need of exploring cooperative approaches for effective phosphorus recovery at regional scale.

Funding Information:The Government of Canada through the Department of Environment and Climate Change provided financial support to Pollution Probe to perform the study of P flows through Ontario's economy in collaboration with Canadian academic experts on P and nutrient reuse and recovery and their teams as part of the Mapping Phosphorus Flows in the Ontario Economy project. This work further builds on findings from the Mapping Phosphorus Flows in the Ontario Economy project in exploring the role for nutrient recovery and reuse technologies and solutions.
