Despite its promise, comprehensive studies evaluating the feasibility of biochar systems remain limited. This research addresses this gap by analysing biochar production via sorption-enhanced gasification (SEG) using sewage sludge and grape seeds as feedstocks. A life cycle assessment evaluates the environmental impacts of producing 1 kg of biochar, while a life cycle costing examines the economic viability of SEG technology. Results show that grape seeds-based biochar yields lower environmental impacts compared to sewage sludge, with GHG emissions of 11.0 and 17.8 kg CO2, respectively. The economic analysis also supports agricultural waste as a more favourable feedstock, obtaining a higher profit of 0.94 €/kg compared to 0.82 €/kg. This study underscores biochar’s potential as a sustainable solution for waste management and soil amendment, while highlighting the need for further optimisation to improve its economic viability. info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Baima, Lorenzo Moles, Samuel Universidad de Zaragoza (orcid)0000-0002-1401-7511 Sierra-Pérez, Jorge Universidad de Zaragoza (orcid)0000-0002-7660-3508 Martínez, Isabel Murillo, Ramón Brun, Filippo Blanc, Simone 1011 660 Universidad de Zaragoza Dpto.
