Plasma-based tertiary recycling offers a profitable solution for converting mixed and contaminated waste into high-grade energy, providing cleaner alternative to fossil fuels supporting sustainable development goals. Technological innovations in plasma generation have enabled efficient waste-to-energy conversion without the need segregation, disinfection, or preprocessing, making integrated gasification viable waste. This review explores recent advancements methods various torch configurations management, evaluating their techno-economic feasibility. Case studies highlight successful applications reducing landfill dependency enhancing circular economy practices. Plasma of 1 kg requires 0.37–0.5 kWh electricity can generate approximately 0.87–0.97 using internal combustion (IC) engines up 1.1–1.47 with gas turbines. From lifecycle assessment disposal methodologies, plasma-based has global warming potential 0.205 CO2 equivalent (CO2e) per waste, compared incineration (0.700–1.2 CO2e/kg), open burning (2.9 landfilling (0.781 CO2e/kg). emphasizes suitability IC (η = 12%–21%), turbines, gas–steam turbines small-, medium-, large-scale applications, respectively. It also artificial intelligence integration management achieve goals by diverting from landfills generating renewable energy by-products. Additionally, it highlights mobile plants 18% overall efficiency direct current arc combined spark ignition engines.
