[Abstract] Pyrometallurgy lead-acid battery recycling causes pollution and is energy-intensive. This research aims to implement an alternative hydrometallurgical process of recycling lead-acid battery paste, NovoPb, by developing processes to make it economically viable in the current market and to ensure the quality of the newly recycled batteries in a 1 ton capacity pilot plant at Minas Gerais - Brazil.<br />NovoPb is based on a paste-to-paste route using a biomass source, citric acid. The new intermediary lead compound is calcined at a much lower temperature (340°C) than usual smelted lead (1200°C), saving energy and reducing hazardous gas emissions such as Pb and SOx, to directly generates nanostructured PbO for battery paste. <br />The process to be deployed in Brazil has as a first challenge the battery scrap characterisation, to measure the use of reagents per ton of scrap, which is not standard protocol in the current pyrometallurgical process. The study of the characterisation forms will be carried out in the laboratory to define the route to be followed in the pilot plant, which will be built by the British partners.<br />The determination of the optimal reaction conditions will be designed by factorial modelling. The influence of the impurities will be evaluated from a pure standard mixture of the main species that compose the battery paste. The optimization of the pilot process will be carried out by application of artificial neural networks after controlled operation.<br />This research is part of the Embrapii project of the Vitoria Innovation Center of the Federal Institute of Espirito Santo, in partnership with the University of Cambridge, Innovate UK, Brazilian companies Tudor MG de Baterias, Antares Reciclagem LTDA and the British company, Aurelius Technology.
