Round 1
Reviewer 1 Report
The proposed manuscript is interesting and useful for energy recovery from organic waste landfills.
I would suggest eliminating formulas 1) and 2) from the Introduction by finding a better location.

Reviewer 2 Report
This study deserves recognition for the detailed data obtained on landfill sites.
However, I would like you to consider amending or adding the following points.
L46-47 "There are different technologies to convert gas to electricity including gas turbine in Brayton cycle, Organic Rankine cycle, Stirling cycle engine [3-4]".
Gas engines are usually the most popular way of generating electricity from landfill methane gas. The ones mentioned are rather specialised.
There are examples of landfill methane gas recovery and energy use around the world. It would be interesting to know what the challenges are in those global cases and how your approach can contribute to them.
