Round 1
Reviewer 1 Report
The authors reported on the Bioremediation of hazardous wastes using green synthesis of nanoparticles. The manuscript could be suitable for publication after the following reviews:
Comments
In the introduction, place more recent articles hazardous wastes
In 5. Mechanism involved in green synthesis, place more mechanisms of nanoparticle formation, for example: Green biomimetic synthesis of Ag–TiO2 nanocomposite using Origanum majorana leaf extract under sonication and their biological activities.
In 6.4. Plant nanoparticles in remediation, it is necessary to add some examples of the degradation mechanisms of some dyes, for example: Study of the optical properties of TiO2 semiconductor nanoparticles synthesized using Salvia rosmarinus and its effect on photocatalytic activity
Improve the quality of all figures
Place at least three green synthesis references in Processes Journal

Reviewer 3 Report
The present review article i.e. “Bioremediation of hazardous wastes using green synthesis of nanoparticles” by Singh et al. focuses on the recent development on the green synthesis of nanoparticles and discussed their application in improvement of environmental conditions. There are certain critical issues within the article that are listed below.
1. Abstract seems to be very generalized (Seems to be generalized introduction of the articles). It needs to be specific to the present studies. In addition, the abstract seems to be free from any abbreviations.
2. Introduction seems to be very weak in term of literature survey. More literature survey is required in all parts especially where the authors discussed the environmental application of greener nanoparticles.
3. Types of nanoparticles seems to very generalized in addition I am not able the understand the role to this section in the present article.
4. There are lot of typing errors in the present article specially with the symbols of the nanoparticles like TiO2, WO3 etc. that needs to be rectified.
5. The section 4. i.e. Green synthesis of nanoparticles seems to be very weak. It needs major revision in term of various protocols developed till now for better presentation. Only three papers are discussed in details
6. Environmental application of the green nanoparticles is very superficially written. I think the authors should take results from the previously published paper and present in the present article.
7. Factor affecting the synthesis is also lagging. Authors should consider these papers for better overview of factor affecting the synthesis. 10.1039/C8NA00318A, https://dl.acm.org/doi/abs/10.1155/2014/417305, https://doi.org/10.1016/j.jclepro.2018.09.015, https://doi.org/10.1016/j.jclepro.2019.04.238
Overall, the review article seems to very weak there several grammatical as well as typing errors throughout the article. Very section seems to very weak in term of literature survey. The major flaw in the present studies is lack of reuse of the already published literature. Authors should reuse the graphs from the literature by taking the permission. In addition, the classification of the nanoparticles needs to be e.g. organic, inorganic or conductors, semiconductors or in different and then discuss these sections in details in term of the synthesis by green route. In addition mechanism should be discussed in details (if possible according to the classes of the nanoparticles). Finally the remediation, should be provided in detail by giving the mechanism of the degradation. Currently the article should undergo a major revision.
