Round 1

Reviewer 1 Report

The manuscript describes circular economy indicators for the assessment of waste and by-products from the palm oil sector. The manuscript is interesting in the process view point. However, the manuscript needs minor amendment before publication:

1. Abstract - did not use abbreviation in the abstract i.e. RFF, EFB, HCRRS, CO
2. Introduction - include any policies (world or national) that support the circular economy and relates with Sustainable Development Goals.
3. Please check. some abbreviations not stated in the manuscript. i.e. CPO, POME, RSO etc..
4. Material and methods: - justify, line 114- an interval of 5 years prior to the investigation (2015-2019)
5. line 121 - provide reasons range of 25 years (2019-1994)
6. Provide references/citation for equation used in the manuscript.
7. Line 303 - which table
8. Figure 1 - not clear
9. Check caption for Figure 2, language for legend in Figure 2
10. Check caption for Figure 3, language for legend in Figure 3
11. Check caption for Figure 4, language for y-axis
12. Page 27, 28, 29 - error, references not found
13. Conclusion - too long, simplify maximum 2 paragraph

Reviewer 2 Report

1. The conclusion part is too long ….. I would like to briefly see the perspective of the researchers on this research in the conclusion section.
2. The introduction section is just a general presentation of very basic information and does not approach the state of the art
