It examines the feasibility of thermochemical processes—combustion and gasification—for the valorisation of solid recovered fuel (SRF) derived from screening wastes, which are the only waste in wastewater treatment plants (WWTPs) that typically have an absence of existing recycling or valorisation processes. Laboratory-scale experiments assessed the technical viability of gasification, and energy balances were calculated for both combustion and the syngas obtained from gasification experiments. Results indicate that both processes are feasible for SRF valorisation. Combustion demonstrated the highest energy efficiency, yielding up to 1.6 MJ per kg of raw SRF, compared to gasification’s maximum of 1.4 MJ. The moisture content in SRF feedstock influences both processes, underscoring the need to optimise moisture levels. Additionally, combustion showed a higher conversion efficiency due to the complete oxidation of the feedstock, whereas gasification produced valuable syngas that can be further utilised for energy production or as a chemical feedstock. The study concludes that, from a purely energetic perspective, combustion is the most efficient process for SRF valorisation. However, gasification offers significant environmental and sustainability advantages, including lower greenhouse gas emissions and the potential for integrating with renewable energy systems, making it a more attractive option for long-term sustainability goals. info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 2.5 2024 ENGINEERING, MULTIDISCIPLINARY 50 / 179 = 0.279 2024 Q2 T1 CHEMISTRY, MULTIDISCIPLINARY 123 / 239 = 0.515 2024 Q3 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 284 / 461 = 0.616 2024 Q3 T2 PHYSICS, APPLIED 101 / 187 = 0.54 2024 Q3 T2 0.521 2024 Computer Science Applications 2024 Q2 Engineering (miscellaneous) 2024 Q2 Process Chemistry and Technology 2024 Q2 Instrumentation 2024 Q2 Materials Science (miscellaneous) 2024 Q2 Fluid Flow and Transfer Processes 2024 Q2 5.5 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Zamorano, Montserrat Torres-Rojo, Juan Carlos Gil-Lalaguna, Noemí Universidad de Zaragoza (orcid)0000-0002-8704-9274 Gea, Gloria Universidad de Zaragoza (orcid)0000-0002-4364-2535 Fonts, Isabel Universidad de Zaragoza (orcid)0000-0001-7035-1955 Martín-Pascual, Jaime 5005 555 Universidad de Zaragoza Dpto.
