Round 1

Reviewer 1 Report

The current study entitled “Characterization of Municipal Solid Waste Compost produced at the different Cleaner Development Mechanism Compost Plants in Uganda” is good. For a better understanding in-depth, it is a need for time to work on this topic. Furthermore, the achievement of potential benefits by using current technology is also dependent on the extensive research work for more exploration. Although the experiment is well organized, yet I suggest a major revision due to the following deficiencies.

Major Concerns

Title

  • Please modify the title it is descriptive.
  • Why in title authors wants to declare Uganda. It mostly creates a sense of local research benefits. However, research recommendations are mostly suggested on a global scale. Please make a conclusive title.

Abstract

  • Systematic abstract is missing. Introduce the need for study in 1-2 lines.
  • Please give a clear-cut point problem source as a problem statement that is tackled in the current study.
  • Give logical reason for the selection of current strategy i.e., Municipal Solid Waste Compost.
  • Quantitative data is also important to support your conclusion. I request the authors please carefully check and rewrite the results part in the abstract. Please provide a percentage increase or decrease in the result part.
  • Please provide a conclusive conclusion that is withdrawn through research in a single line.
  • Please conclude with a statement that shows a knowledge gap covered, potential beneficiaries and specific recommendations as well.
  • Give future prospective in a single line. At least declare one best treatment. Please do not make vague statements as in science no space for that.
  • As per standard suggestions, please avoid using title words as keywords

 

Introduction

  • Please follow the title in the introduction section, i.e., Municipal Solid Waste Compost, different Cleaner Development Mechanism, Compost Plants, knowledge gap, hypothesis and aims.
  • Also, provide a novelty statement at the end. What new things authors have done or correlated in this research compared to old ones?
  • Would you please give a single line about the knowledge gap which your research has covered along with the SMART (specific, measurable, achievable, realistic and time-specific) hypothesis statement?

 

Material and methods

  • Move statistical analysis at the end of material and methods.
  • Fertility Index (FI) =. I am unable to understand this equation. Please complete it.
  • Clean Index =. I am unable to understand this equation. Please complete it.

Results

  • Give quantitative data in terms of percentage increase and decrease.
  • Give details of treatment below the tables. All tables should be self-explanatory.

Discussion

  • Please provide a definite mechanism associated with the results. Discussion part is very weak. Please incorporate at least 3-4 paragraphs showing major mechanisms due to which authors got such results

Conclusion

  • Add the targeted beneficiary audience who will get benefits from this research.
  • Also, give clear-cut recommendations
  • Give future prospective regarding this research.

Reviewer 2 Report

The manuscript "Characterization of Municipal Solid Waste Compost produced at the different Cleaner Development Mechanism Compost Plants in Uganda" was written well. However, authors need to address the following comments through minor revisions,

1) Though MSW composts produced at CDM plants were not suitable for use as fertilizers (Class RU-1), still appreciable that used as soil conditioners. 

2) Is it possible to amend with high nutritive waste co compost materials for high-quality compost products?

3) Is any recent data available (at least from 2015-2022) regarding the waste generation rate?

4) Did you tried any maturity index analysis (eg.) phytotoxicity analysis etc

5) If possible, authors may include one table regarding heavy metals limitations from the Uganda government, USEPA, etc., for comparison.
