Reviewer 1 Report

This work reported the findings of a survey on reuse of faecal sludge co-compost in a region of India. Many useful information can be obtained from this work identifying factors influencing negative perception of the use of this product, with the purpose of focus accurately the strategies to promote this product can be properly focused, and so the contribution to the agriculture circular economy. The document is very well written and it follows a logic structure. I recommend that this work is accepted to be published after some minor corrections and questions.

 

• Do the farmers really know what CO compost was before responding the survey?
• Can the authors point out in the discussion any positive case in the world, if exists, where co composted faecal sludge is been successfully and extensible used in agriculture in a country/region. And which policys where implemented to achive high approval rate among famrmers.
• Describe what is KoboCollect                                              line 149

1. Conclusion missing limitation of the study
2. It is unclear how the negative perception agaisnt use of faecal sludge in compost can be changed. Please give some recommendations based on other studies. Create a new subsection dedicating to this issue.

Reviewer 3 Report

The manuscript is generally well written. I only have a few minor observations:

Lines 40- 41: This phrase is a central hypothesis of the manuscript. Then it would seem appropriate to support it with broader studies than [4], since it only refers to maize production. In a quick search I found these works that the authors could (or find better ones):
