Environmental Assessment of Solid Recovered Fuel Production from Screening Waste Using a Life Cycle Assessment Approach De la Torre Bayo, Juan Jesús Zamorano Toro, Montserrat Torres Rojo, Juan Carlos Pennellini, Sara Martín Pascual, Jaime Bonoli, Alessandra Environmental analysis Circular economy Waste to energy The circular economy, as a new model of waste management through energy self-sufficiency and valorisation, can be applied to wastewater treatment plants (WWTPs). Screening waste from WWTP pretreatment is the only waste that is not energetically recovered and thus constrains the achievement of zero waste. Previous studies demonstrated the technical feasibility of producing solid recovered fuel (SRF) from this waste. Environmental benefits, including waste reduction, resource conservation, or reduced greenhouse gas emissions are analysed in this work. Environmental impact is quantified using the life cycle assessment (LCA) methodology through the SimaPro 9.2. software and the CML-IA baseline v3.08 impact methodology, that propose 11 impact categories. Five scenarios were established to compare current landfill disposal with the production of densified and non-densified SRF using solar and thermal drying. Within the system boundaries studied, from waste generation to SRF production, results show that landfill is the most environmentally damaging option while producing non-densified SRF using solar drying is the most environmentally viable scenario. 2024-09-16T10:08:31Z 2024-09-16T10:08:31Z 2024-08-26 journal article De la Torre Bayo, J.J.; Zamorano, M.; Torres-Rojo, J.C.; Pennellini, S.; Martín-Pascual, J.; Bonoli, A.
