Closing the Nutrient Loop: The Strategic Potential of Human Waste (lemonde.fr)

• Human waste recovery as a solution to synthetic fertilizer dependency.
• Addressing geopolitical vulnerability in agricultural supply chains.
• Infrastructure development for closed-loop nutrient management.

"Engineer Fabien Esculier advocates for the systemic recycling of human urine and feces as agricultural fertilizer. By tapping into this underexploited resource, Europe can significantly decrease reliance on synthetic fertilizers, which are vulnerable to price volatility and geopolitical supply disruptions. Integrating nutrient recovery into modern wastewater infrastructure provides a pathway toward agricultural resilience and reduced environmental impact, echoing traditional farming methods while applying contemporary scientific rigor to stabilize food security."
