Round 1

Reviewer 1 Report

The manuscript is a systematic review of life cycle assessment based publications related to the subject of sustainable agri-food processes and circular pathways.

the manuscript appears to be well researched, with a concise reference list.  Figure 2 summarises the approach in a transparent and easy to evaluate format. the comments below are minor.

Abstract line 19 - CE needs to be written in full

line 241 the sub heading 3.1 states 'Descriptive statistics' - i was unable to locate any statistical procedures in this section other than to describe the number of publications per year or by country.  this is summary data but not a statistical analysis and therefore should be rephrased.

Figure 3 Publication trend by year - advise that the year 2021 is not included as this is not a complete year and makes the shape of the graph mis-leading

line 785 the authors note that there is a lack of a specific stand-alone social impact assessment method in the papers reviewed and assessments overall.  There is then a bias towards the environmental side of the three pillars of sustainability (environment, economic, social)?  Can they suggest a potential approach that could be used?

Reviewer 2 Report

Dear Authors,

The manuscript (sustainability-1113217) presented for review is very interesting and I recommend the article for publication in Sustainability Journal but after correction. In my opinion, the manuscript is a little bit too long, if the Authors try to shorter text will it be better for readers.
