Composted organic waste, enhanced with biochar-rich materials, could serve as an effective component for these media. This study aimed to evaluate the agronomic performance of six different substrates made from organic wastes (spent coffee grounds, coffee silverskin, and seaweeds) composted with or without biochar as alternatives to peat for rooftop agriculture. Over three years, substrate fertility, crop yield, and quality were assessed using a tomato variety (Solanum lycopersicum L., cv. Moruno de Aranjuez) and a consociation of lettuce (Lactuca sativa L., cv. Romana) and chard (Beta vulgaris var. Cicla). A peat-based substrate and open-field conventional cultivation on soil served as controls. Co-composted substrates significantly increased productivity by 102 % compared to peat-based controls and by 43 % compared to open-field systems. For lettuce, compared to peat-based control, compost-based substrates without biochar yielded 380 % more in the first year, while those with biochar yielded 149 % more in the second year. Additionally, incorporating biochar during composting improved tomato quality, making it comparable to that achieved in open-field cultivation systems. In conclusion, co-composting organic waste with biochar to obtain growing substrates presents a sustainable alternative for city-focused rooftop agriculture, providing considerable horticultural yields that could reduce the environmental impact of the urban food needs.This work was financially supported by the Comunidad de Madrid and the Spanish National Research Council (CSIC) through the research grant Atracción de Talento (2019T1/AMB14503), and by the Spanish Ministry of Science and University MICIU/AEI (/10.13039/501100011033) through the grant “Consolidación investigadora” (CNS2022–135684) funded through the European Union NextGenerationEU/PRTR programme.Peer reviewedElsevierComunidad de MadridConsejo Superior de Investigaciones Científicas (España)Ministerio de Ciencia, Innovación y Universidades (España)European CommissionPicca, Giuseppe [0000-0001-5423-0993]Lozano de Sosa, Laura [0000-0002-4156-1897]Plaza de Carlos, César [0000-0001-8616-7001]Panettieri, Marco [0000-0003-4769-8955]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202520252025info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/385132reponame:DIGITAL.CSIC.
