However, primary extraction poses increasing environmental problems because of the progressive decline in the mineral concentration of copper deposits (ore grade). In this context, electronic waste is becoming a very promising source of secondary copper. However, this form of copper recovery presents a number of technological and chemical challenges, including the use of renewable energy, separation of plastics from other waste, and increasing process efficiency. Given the thermodynamic limitations of these processes, other non-technological factors are becoming very important in the transition. info:eu-repo/semantics/openAccess by-sa https://creativecommons.org/licenses/by-sa/4.0/deed.es 0.5 2024 0.133 2024 Multidisciplinary 2024 Q4 History and Philosophy of Science 2024 Q4 1.0 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Valero, Alicia Universidad de Zaragoza (orcid)0000-0003-3330-1793 5004 590 Universidad de Zaragoza Dpto.
