Abstract

A gliding arc plasmatron (GAP) was proposed for efficient degradation of mixed microplastics (MPs) under simplified and adaptable conditions. Complete degradation of MPs can be achieved within 2–4 minutes, with non-hazardous CO₂ as nearly the only gas product. The catalyst-free GAP system, with its simplicity and compatibility with distributed renewable energy supply, offers a sustainable solution for MP treatment.
