I've seen this journal listed in the predatory journal list. But it has been included in the library of Purdue University, Indiana University, and also has impact factor of 3.1. I need confirmation on this issue.
As you already indicated the journal “International Journal of Environment, Agriculture and Biotechnology" is mentioned in the stand-alone version of the Beall’s list (https://beallslist.net/standalone-journals/ ). This is by itself not enough to say they are predatory but be sure that in this case this is a predatory one since the things you mention confirms this:
-The prominently mentioned impact factor is something called “Root Indexing” and this is an example of a so-called misleading metric (https://beallslist.net/misleading-metrics/) often used by predatory journals/publishers
-The logo of the Purdue University is meaningless (and if you click on it in no way linked to this ‘journal’)
There are many more red flags (Showing the Thomson Reuters logo for example is for numerous reasons completely pointless and at least misleading), looking at the contact info https://ijeab.com/contact-us/ they mention as publisher behind this journal “Infogain Publication” and they are mentioned in the updated publishers version of the Beall’s list (https://beallslist.net/#update ).
