Recovery of urban waste

The Brazilian Aluminum Company (Companhia Brasileira do Alumínio, CBA) signed a collaboration agreement with the CNPEM in 2020 and again in 2021 for specialized technological services to scale up its process of recovering aluminum from urban waste. These activities involved pilot-scale experiments to validate a protocol developed by the company. Different methods and experimental arrangements were used to better understand the industrial production conditions and successfully replicate the lab-scale results. According to Roberto Seno Junior, Technology Manager at CBA, the partnership with the CNPEM benefits both parties, especially for new technologies, since “the process of developing new products and solutions requires a strong connection with the market to quickly respond to demand and absorb this learning.”
