Should the Sludge Hit the Farm? : How Chemo-Social Relations Affect Policy Efforts to Circulate Phosphorus in Sweden

This article discerns why the substantial political efforts to increase circulation of nutrients in sewage sludge, and phosphorus in particular, have shown such meager results over the last twenty years in Sweden. We have analyzed stakeholders’ statements of opinions to four government-initiated inquiries, to decipher the chemo-social relations between stakeholders and phosphorus, and how these relations have transformed over time and made a difference in the policy process. In our analysis, we found five different relations: 1) a metabolic, 2) a purity, 3) a nutritional, 4) a marketable, and 5) a geopolitical. These relations connect actors, phosphorus and politics in different ways, and obstruct policymaking by creating tensions between political objectives, values and stakeholder positions. We observe how the extraction of phosphorus as a singular, marketable element to be sold for profit reasons on a global market, is increasingly favored in comparison to local eco-cycling of nutrients between farmers and consumers. We see this as a consequence of that the circular economy as a concept has replaced eco-cycle efforts in the Swedish policy debate. We conclude that if circular economy-initiatives are to be successfully implemented, they need to be informed by the current configuration of material flows that they wish to transform as well as the political implications of their efforts. So far, this has not been the case regarding sewage sludge in Sweden.
