Reviewer 2 Report

 Dear Sir,

 Greetings!

 The submitted manuscript "Effects of sludge concentration and sludge disintegration and solubilization pretreatment methods on increasing anaerobic biodegradation efficiency and biogas yield". The paper is too general, not suitable as per my opinion. Please highlight the novelty of work in right manner. Clearly discuss outcomes and what research gaps it covers. Please show how this paper has a strong correlation with sustainability concerns. 
Grammar and syntax must be improved. Revision with the help of a native English speaker is highly recommended.

 Thanks
