Superworm Gut Biodegrades PVC Microplastics Through Host–Microbe Interactions

Caption

Fig 1: Illustration showing how Zophobas atratus (superworm) larvae ingest and biodegrade high-purity PVC microplastics inside their gut. The graphic highlights the gut as a host–microbe-driven microenvironment with elevated reactive oxygen species (ROS), where PVC undergoes chain scission, oxidation, and dechlorination. The process results in reduced particle size and molecular weight, weakened C–Cl bonds, formation of chlorinated organic intermediates, and partial mineralization into CO2, H2O, and chloride ions before excretion.
