International efforts are being made to reduce environmental pollution caused by microplastics (MPs). Microplastics released into the environment through sewage treatment sludge, and use of sludge as a soil improvement agent is increasing rapidly, emphasising importance controlling in facilities. The release an increasingly significant concern, with sources including sludge. This study focuses on analysis using optical (Fourier-transform infrared spectroscopy, FTIR) thermal (Thermo Extraction Desorption–Gas Chromatograph–Mass Spectroscopy, TED-GC-MS) processing-based analytical equipment. average amount MPs analysed FTIR was 228.5 microplastics/g (MPs/g), primarily polypropylene type. Approximately 75% were 0.1 mm size or smaller. However, determined TED-GC-MS 95.79 µg-MPs/g. For systematic management microplastics, it important estimate generated plants. Therefore, microplastic generation calculation formula proposed used potential total from plants South Korea, calculated equation, approximately 364 ton/yr; we further divided administrative regions. findings this can be applied assess global trends MP research.
