Microplastics in an anaerobic digester treating sewage sludge: Occurrence and factors affecting their identification with Raman spectroscopy

Journal of Hazardous Materials, Journal Year: 2025, Volume and Issue: unknown, P. 138015 - 138015

Significant share of microplastics entering wastewater treatment is accumulated in sewage sludge, which commonly treated by anaerobic digestion. The digestate typically separated to solid and liquid fractions, the fraction often land-applied. However, division between these fractions poorly understood. Thus, we investigated occurrence (>20 μm) at an digester subsequent solid-liquid separation. Sewage sludge exhibited 7600 ± 6800 7200 1100 per g dry weight, respectively, indicating that digestion can decrease fluctuation microplastics' sludge. microplastic flow was predominantly directed fraction, while carried about 1 % microplastics, mostly polymers with low density (polyethylene polypropylene). We also factors affecting identification Raman spectroscopy. Microplastic degradation presence organic matter after oxidative sample preparation, affected spectra different microplastics. For polyethylene polypropylene, changes did not interfere recognizing their characteristic peaks, allowing high-certainty identification. In contrast, polyamide notably compromised as signal-to-noise ratio be deteriorated natural misidentified polyamide.
