Estimating the Potential for Waste Heat Recovery in Italian Dairy Sector Using a Bottom-Up Approach and Data from Energy Audits
Round 1
Reviewer 1 Report
This paper estimates the potential for waste heat recovery in the Italian dairy sector using a bottom-up approach and data from energy audits. The paper is well-organized and interesting. However, there are a couple of areas that could be improved:
-
It is not clear whether an uncertainty analysis was conducted for the data obtained in this paper. This would be an important aspect to consider and should be addressed.
-
It is important to keep the format of the references consistent throughout the paper. Please ensure that all references follow the same format.
The quality of the English language used in this text is good, making it easy to follow.

Reviewer 2 Report
The authors have submitted an interesting paper that estimates the potential for waste heat recovery in the Italian dairy sector using a bottom-up approach and data from energy audits. The paper is well prepared and suitable for the Sustainability journal. The paper has potential for practical use, but I have a few notes for the authors:
1. Please check the SI units in equations (1)-(6) and the variables in the explanatory text.
2. What are the operating costs of recovery units in the food industry? What are the state subsidies for the introduction of recuperation systems? Please discuss it more.
3. There could be considered added comparison of the effectiveness of different recovery technologies for the food industry.
4. In discussion, authors should discuss the results and how they can be interpreted from the perspective of previous studies. The findings and their implications should be discussed in the broadest context. Future research directions may also be highlighted. The practical use of the proposal should be more emphasized.
I suggest accepting the paper after minor revision.
I wish the authors success.
Please re-read the text and correct minor errors.

Reviewer 3 Report
The work needs to be improved. The numerical values of the results are to be included in the abstract. Authors should provide nomenclature to reflect all the abbbreviations and parameters used in the study. Also, the obtained results in this study are to be compared with existing results especially those of dairy industries. An annotated version of the manuscript has been provided for the authors to work with in addressing some issues addressed concerning the manuscript.
