Hi. Yes my dear.

Dear Professor,

I am also interested to contribute as a coauthor in the special issue with suitable authors.

Yes

I look forward to your contribution

Very interested but the article processing charge is a non-starter for some if not most when many journals publish papers at no charge to the author/organization.

It is the negative part of the open access option.

Yes

The first contributions are already being received, so when you want you can send your valuable contribution

Yes , thanks for contribute updated follow up my biofuel braxilan 20 years pos dr reseach work as well as online learning and teaching too

Is the theme also include biogas production?

Biogas, as a biofuel in broad sense, can be considered a biofuel, so it could be part of the special issue, as long as it is accepted by the reviewers.

me too think so as biogas from gycerine aste oil too can hep otimize the sstem

Yes

I'm sorry but currently there is no exception or exemption in the fees
