The global coronavirus (COVID-19) pandemic in early 2020 caused the amount of medical waste, especially plastic to increase. exacerbated waste management problem, including need find more sustainable treatment methods. This study investigated conversion (FFP2-type face masks) syngas via pure CO2 plasma gasification recover energy and reduce environmental pollution. A direct current (DC) thermal arc torch 40.6–68.4 kW power generated stream. Carbon dioxide (CO2), as a greenhouse gas (GHG), was used main plasma-forming gasifying agent. 140thermal feedstock input system study. effect CO2-to-C ratio on performance efficiency investigated. best process obtained at 2.34. In these conditions, components (H2 + CO) comprised 80.46 vol.% (H2: 24.62 CO: 55.84 vol.%) following values were seen for heating value (LHVsyngas: 13.88 MJ/Nm3), yield (3.13 Nm3/kgFFP2), tar content (23.0 g/Nm3), carbon (CCE: 70.6%), cold (CGE: 47.8%). Additionally, mass balance evaluated. It demonstrated that could be promising thermochemical technology disposal simultaneous utilization gases, such dioxide.
