The rapid development of population, urbanization, and industrialization increase the consumption of modern products that generate electronic waste (e-waste) globally. Efforts to overcome e-waste in the context of circular economy exist, but a lack of agreement among researchers and practitioners' challenges how to best measure success in the e-waste circular economy. This study aims to address critical success factors (CSFs) of the e-waste circular economy to assess the maturity levels of urban mining. Maturity levels of urban mining are developed by employing Key Performance Indicators (KPIs) that derive from how well CSFs are executed. The maturity level is modeled by adding all scores of KPIs aligned with CSFs. Automatic Content Analysis is used to extract keywords and interpret the relationship among keywords to form initial factors in CSFs from a set of related articles on e-waste management. These initial factors are further analyzed by subject experts using facet analysis to construct KPIs in line with the CSFs. The experts' score determines the maturity level of urban mining: initial, emerging, developing, established, and mature. From the experiment, we found seven factors in CSFs and 34 indicators in KPIs. Three countries (Indonesia, India, and Japan) were used as the trials of the assessment of urban mining maturity level. Indonesia's urban mining maturity level is considered emerging with a score of 54, and the same score is reflected in India. With a score of 114, Japan has reached an established stage. Furthermore, the results of urban mining maturity level assessment can be used as guidance to choose and prioritize SDGs. According to urban mining indicators identified, the successful implementation of sustainable urban mining can play important roles in promoting sustainability development goals, especially including SDG 9, SDG 11, SDG 12, SDG 13, SDG 17, SDG 7, SDG 6, and SDG 8.
