Abstract
The wastewater chain of Amsterdam offers an opportunity to recover up to 100% of phosphorus per year, versus 47% currently recovered. However, for the stakeholders of Amsterdam (e.g. citizens, business) it remains difficult to scale-up existing solutions for resource recovery. Mainly, due to the limitations of the widelyused methods (e.g. mass flow, life-cycle analysis) to provide holistic assessment of the solutions and the changes they will propagate outside the wastewater chain (e.g. solid waste). In the current study, three existing phosphorus recovery Solutions applied at three scales of Amsterdam (city, neighborhood, house) were analyzed. The study showed that the house scale closed-loop solution has higher positive influence on resilience of the city. Moreover, the DSM indicators could be used to measure resilience of the city and constituent parts, given an influence of a specific Solution. The developed toolkit is applicable for analysis of other resources in the wastewater of Amsterdam.
