ICCESEN (http://www.iccesen.org) is a large international platform where high-quality papers are presented in different fields within environmental-related works. There were 10 different main themes in ICCESEN and most of them cover environment and related sciences. In this special issue, papers from ICCESEN and also related papers from outside were accepted and they will clearly produce a good contribution to the literature. I am thankful to all committee members-participants and authors of manuscript for contribution to ICCESEN. Finally, I would like to sincerely thank the International Journal of Environmental Science and Technology (IJEST) and Editorial Office collaborating with us and helping all steps on publication process of those manuscripts.
