We have organized this conference in order to offer a forum for discussing the cutting-edge research and for sharing the most recent breakthroughs in green chemistry and engineering. In addition, we hope this symposium can help chemistry and engineering scientists, practitioners, policy makers from the developing countries as well as the developed countries to better communicate with each other. We are grateful to our sponsors and exhibitors for their generous support and assistance for this conference. I would like to extend our thanks to the all Symposium Chairs, Conference volunteers, Invited Speakers and to all of you who came to present and share your wonderful research work!
