The Paradigm of Circular Economy and an Effective Electronic Waste Management
Round 1
Reviewer 1 Report
This manuscript describes the current situation of circular economy to create a zero-waste city. This study emphasizes the role of effective e-waste management as a crucial part of a circular economy. The work has been carried out with care and the results have been presented with clarity and discussed appropriately. In addition, the collection of e-waste, recovery of items such as virgin materials and metals, and segregation and safe disposal of hazardous substances, are the main services that a complete electronic waste system to ensure sustainability. In this way, this manuscript demonstrates a significant contribution in the area of sustainability. Accordingly, I can recommend publication of this work in Sustainability after solving the issues detected.
Issues:
- Authors should check grammatical or formatting errors.
- Authors should check and put the bibliography in the correct format. In addition, should begin referencing the bibliography in the text with reference number 1 and then continue with reference number 2 and so on. The text cannot begin with reference 24.
- Authors should complete these sections: Author Contributions, Funding, Institutional Review Board Statement, Informed Consent Statement, Data Availability Statement, Acknowledgments, and Conflicts of Interest.
- This investigation/manuscript should make a comparison of this methodology over others and demonstrate the improvement and advantage of this methodology over other methodologies.

Reviewer 2 Report
There is no order in the references.
The abstract should be revised and improved.
The document addresses an Effective Electronic Waste Management; however, it does not mention any successful case that is being carried out in any part of the world or management strategies in certain countries, and from there contrast with the management that reaches predominate in different societies.
Everything remains very general and there is little relationship between sections such as abstract and conclusion
