Plasma Gasification of Medical Plastic Waste to Syngas in a Greenhouse Gas (CO2) Environment

Sustainability, Journal Year: 2025, Volume and Issue: 17(5), P. 2040 - 2040

Published: Feb. 27, 2025

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.

This research paper analyzes the use of plasma technology to process biomass in form dried, mixed animal manure (dung containing 30% moisture). The irrational as well huge quantities it can negatively impact environment. In comparison fermentation, processing greatly enhance production fuel gas, primarily synthesis gas (CO + H2). organic part dung, including moisture, is represented by carbon, hydrogen, and oxygen with a total concentration 95.21%, while mineral only 4.79%. A numerical analysis dung gasification pyrolysis was conducted using thermodynamic code TERRA. For 300–3000 K 0.1 MPa pressure, were calculated 100% 25% air nitrogen, respectively. Calculations performed determine specific energy consumption process, composition products gasification, extent carbon gasification. At 1500 K, consumed 1.28 1.33 kWh/kg energy, direct-current torch power rating 70 kW reactor capacity 50 kg/h used for experiments. 1.5 1.4 when pyrolyzing gasifying dung. maximum temperature 1887 reached reactor. plasma–air produced gases heats combustion 10,500 10,340 kJ/kg, experiments on showed satisfactory agreement. this research, exergy quantify efficiency biomass.
