Characterization of Biobriquettes Produced from Vineyard Wastes as a Solid Biofuel Resource

Round 1

Reviewer 1 Report

Manuscript title: Biobriquettes production from vineyard wastes as a new solid 2 biofuel resource

Manuscript Id; agriculture-1585993

General comments,

The title of the research paper should have to be changed because the authors are already done the briquet production and published the results.

My suggestion “characterization of briquet produced from vineyard waste” this only my suggestion

Various ideas are explained in one paragraph in the introduction section, very boring to read, I highly recommend that to divide the introduction section into many paragraphs

Overall,

I wonder if there is a difference between your previous paper and the current one. I am curious to learn that. I found that the paper entitled “Sustainable biomass pellet production using vineyard wastes” (https://doi.org/10.3390/agriculture10110501) was rewritten.

Reviewer 3 Report

Here are my comments:

1. The introduction should be supplemented by other recent studies in the literature on briquettes, pellets or firelighters obtained from residues in the food industry and agriculture.
2. There are a number of inconsistencies between the presentation of the characterization techniques used and the results obtained. For example, section 2.5.1 shows that the thermogravimetric curves were recorded in the temperature range 30-100°C. But if we look at figure 4 we notice that the test ended at a temperature of 1000°C.
3. The characterization techniques used must be presented more carefully and complete information must be provided about the working atmosphere (at TGA Analysis), about the amount of test used, about the reproducibility of the results obtained.
4. The TGA section of Briquettes must be rewritten. First of all, in figure 4 did the authors represent the DSC curves??? According to the units of measurement presented, these are the DTG curves.
5. The authors named one of the heating processes accompanied by a mass loss of 54.585%. They must consult the specialized literature and correctly interpret the way in which the thermal decomposition of the obtained briquettes takes place. Figure 2 shows the chemical compositions of briquettes. It must correlate this composition with the decomposition mechanism. The results presented in the TGA section of Briquettes are not reported in other existing studies in the literature.

6. The conclusions section must be rewritten and completed. The authors state that they obtained a large amount of CO due to incomplete combustion. They should take into account that the TGA analysis shows a small amount of 1.83% residue.
