Overview

Narrative review reveals significant environmental and health risks from emerging contaminants in sewage sludge fertilizers, highlighting the need for robust treatment and clearer regulations.

Key Points

To evaluate the safety-related challenges, contaminant risks, treatment technologies, and regulatory frameworks associated with recycling sewage sludge for agricultural fertilizer production.
Conducted a structured narrative review analyzing published literature on sewage sludge composition, agricultural reuse, and environmental pathways.
Evaluated the presence and behavior of primary contaminant classes, including heavy metals, biological pathogens, microplastics, and pharmaceuticals.
Reviewed stabilization and mitigation techniques such as anaerobic digestion, composting, thermal/chemical treatments, and mechanical granulation.
Identified that heavy metals, persistent pathogens, microplastics, and emerging pharmaceutical residues present substantial contamination risks to soil, water tables, and food chains.
Determined that advanced pre-treatment methods, notably thermal processing, anaerobic digestion, and composting, are vital to decontaminate and stabilize sludge prior to field distribution.
Highlighted widespread regulatory gaps regarding standardized treatment mandates, enforceable contaminant thresholds, and clear safety criteria for agricultural reuse.
