If you are really into writing journal, I mean good quality journal, that is merge chemical engineering and environmental, here is one new journal that you may want to consider. It is the new “Journal of Environmental Chemical Engineering“. Up to the moment this post is published, the journal present Volume is 1 and Issue is 3. The first volume and first issue was published in June 2013.
The journal is another product from Elsevier with ISSN: 2213-3437. Since it is new, the journal does not have any Impact Factor (IF) yet. Just wait for few years and I believe the IF will be an encouraging one. To review among the first research publication in this journal, you can click here and read the interesting topics available.
