Line 29: unfinished phrase, meaningless

Increase of electrical parameters using sucrose in tomato waste

You're right, it was removed.

Line 115 -116: I don't understand the punctuation mark

where 180 mL of waste were used. tomato per cell.

You are right, it was corrected.

Reviewer 2 Report

The article "Increase of electrical parameters using sucrose in tomato waste" was reviewed. Please address the following Problems:

1. The Abstract part is weak and it must be more informative by including more mathematical findings and more powerful explanations.

2. In the "Introduction" section, the general description of the importance of the manuscript topic is poor. Therefore, the importance of this work cannot be well recognized by general readers. The introduction can be improved by providing a more critical discussion of recent related literature. Discuss the shortcomings of previous work and the gaps and how this work intends to fill those gaps. Related references should be cited:  Journal of Industrial and Engineering Chemistry, 105, pp.111-120.    " Materials Today Chemistry 24 (2022): 100763.

3. Please rewrite the Conclusions. It must be fully supported by the results reported and should include the major conclusions, the limitations of the work, and future work.

 4.  Remove the grammatical and typo mistakes.  Section 2.2. last line after a period "tomato per cell",   Abstract last line "Increase of electrical parameters using sucrose in tomato waste"  Please check carefully and complete the sentences. 

5.  Explain the mechanism behind the current generation of current scenario.

Reviewer 3 Report

1. why did author choose the tomato? 

2. How did author calculate internal resistance in Fig 5. Fig 5 showed that voltage was constantly kept with increasing current. Does  It mean internal resistance decreased with increasing current? 

3.  what kind of method was used for tomato waste extract in this study? 

4. electricity generation is affected by organic matter. but in this study, there was no information about organic matter initial and final COD or TOC., and please provide the chemical characteristic of tomate waste 

5. more in-depth discussion should be required for all results. 

4. Please make the color the same for each condition in fig 2. 

5.  Please check colors of symbols in fig 3. 

6.  Please provide the detailed information about target, 5%, 10%, and 20% in all figuress. 

 

Author Response

Dear colleague, I send the corrections with the answers to each question.

1.why did author choose the tomato? 

Mainly, because the tomato residues are very abundant and very produced in Latin America; Motivo por el cual ya se ha realizado un trabajo anterior a este y es a prolongacion de la misma: para lograr los valores mostrados electricos.

1. How did author calculate internal resistance in Fig 5. Fig 5 showed that voltage was constantly kept with increasing current. Does  It mean internal resistance decreased with increasing current? 

The internal resistance was found using the energy sensor (Vernier-±30 V and ±1000 mA), on the day where its maximum peak current and voltage were observed.

About the second question, no; current and voltage values are separate parameters; As indicated by the internal resistance, it was taken in a single day; where the maximum peak of these two values was observed.

3. what kind of method was used for tomato waste extract in this study? 

tomato waste was ground naturally, with all its components in order to work it as it is found in the markets. In order to be as realistic as possible

4. electricity generation is affected by organic matter. but in this study, there was no information about organic matter initial and final COD or TOC., and please provide the chemical characteristic of tomate waste 

The authors are aware of the comment, but the equipment is damaged and was carried out without observing these values; reason for which he focused on the electrical parameters produced. For future research, these parameters will be taken into account.

5. more in-depth discussion should be required for all results. 

Added some discussions

4. Please make the color the same for each condition in fig 2. 

In Figure 2, all sucrose percentages have the same color (target: black, 5%: red, 10%: blue, and 20%: green)

5. Please check colors of symbols in fig 3. 

ok

6. Please provide the detailed information about target, 5%, 10%, and 20% in all figuress. 

all the figures are with their corresponding coding, the white name was added in some to make it easier to identify

best regards

Reviewer 4 Report

Power production obtained with a mixture of tomato wastes and sucrose showed that there is an increase in voltage and electric current and this effect increase with the sucrose concentration.

 

In my opinion, there is no correlation between sucrose and power production as well as there is no definition of a strategy for the organic wastes at the end to understand if MFCs with wastes could represent a viable for power production at a large scale.

Ref: In my opinion, there is no correlation between sucrose and power production as well as there is no definition of a strategy for the organic wastes at the end to understand if MFCs with wastes could represent a viable for power production at a large scale.

 

Ans: The opinion is respected, but in previous works the generation of electricity using tomato waste has been demonstrated and this research has a future because the generated voltage was enough to turn on an LED bulb (see image) with 3.43 V connected the MFCs in Serie. In our opinion and experience in this investigation; and having reviewed the literature, sucrose has influence due to the variations of the electrical parameters observed.

Round 2

Reviewer 3 Report

1.  author explained why you chose the tomato, so pleas add the explanation in introduction part. 

2. author also explained internal resistance of fig 5. However, I think fig 5 is voltage-current curve. internal resistance was calculated with Ohm's law as you mentioned. And internal values in text were different from those in figs. Please check thoroughly those values. 

3. And also, internal resistance can be calculated in voltage-current curve of fig 3. 

4. Internal resistance in this study is relatively much higher than previous studies. How do you think about this? 

 

5. author changed colors in fig 2 and fig 3. but in fig 2, symbol of 10% in fig 2a looks like yellow and  there was no red symbol in fig 2c. Please change green of symbol color of power density to red  in fig 3a.

1. author explained why you chose the tomato, so pleas add the explanation in introduction part.

changes made

2. author also explained internal resistance of fig 5. However, I think fig 5 is voltage-current curve. internal resistance was calculated with Ohm's law as you mentioned. And internal values in text were different from those in figs. Please check thoroughly those values.

exact values were obtained by ohm's law, the values were verified.

3. And also, internal resistance can be calculated in voltage-current curve of fig 3.

Yes, but it was chosen using the energy sensor equipment (Vernier-±30 V and ±1000 mA).

4. Internal resistance in this study is relatively much higher than previous studies. How do you think about this?

Aunque lo dicho es verdad, también es mucho menor a otros. El aumento de este pametros depende mucho de  diferentes factores, pero en esta investigación se intento dar a conocer los valores obtenidos sin manipular nada mas que el incremento de sacarosa.

 

5. author changed colors in fig 2 and fig 3. but in fig 2, symbol of 10% in fig 2a looks like yellow and there was no red symbol in fig 2c. Please change green of symbol color of power density to red in fig 3a.

It appears to be an error, when submitting and sending; try to change the format to see if you can see it now.
