A Resilient In-Situ Raman-Based Framework for Identifying Thermally Aged Microplastics

The foundational paper behind OpenMNP. In-situ Raman spectroscopy captured real-time spectral evolution of 8 plastics during thermal transformation (25°C to 800°C), building the first comprehensive library for thermally aged microplastics. The method elevated the median spectral matching degree from 47% to 91% and reduced unassigned spectra by 76%.

Study Using OpenMNP Raman Method Reveals Microplastic Distribution in Soils Near Waste-to-Energy Plants

Researchers applied the OpenMNP Raman identification workflow to characterize microplastics (>3 μm) in soil surrounding a waste incineration plant. The study reported 419–1,133 particles/g, with PP and PE accounting for 61.2% of total polymers, validating the method’s real-world applicability.

Atmospheric Microplastics Emission from Waste Incineration: Field Evidence Using OpenMNP

Direct field evidence of atmospheric microplastic emissions from a circulating fluidized bed incinerator, using the OpenMNP Raman identification framework. The study estimated emissions at 2.1×1012 particles/yr, identifying PVC and polyacrylamide as major polymer types, confirming MSW incineration as a significant contributor to atmospheric microplastics.
