Conceptual design for data flow for a database management system for the sustainable recovery of critical metals from waste electrical and electronic equipment

Sustainable recovery of critical metals (CM) from Waste Electrical and Electronic Equipment (WEEE) in the European Union (EU) requires information for detailed analysis, monitoring and decision-making. Related knowledge is currently insufficient or disseminated through the network of stakeholders. This paper assesses the requirements of an adequate Database Management System (DBMS) with participation of different actors involved in the recovery of critical metals and analyses the difficulties and the possibilities found for its implementation. The authors define a conceptual scheme of a DBMS to assess the information requirements and to establish the interactions between different actors of the WEEE supply chain, with the aim of supplying standardized information for management and research. Barriers are studied through a survey to identify obstacles for its elaboration. Limitations for its development are addressed and practical solutions for its elaboration are presented.
