According to the Public Relations of the university: Considering the mission-oriented approach of Qom University of Technology in the field of environmentally friendly industry, this university has participated in the 15th International Environment Exhibition with the slogan "Post-Sanction Green Economy" held at the permanent venue of international exhibitions in Tehran.
In the Qom University of Technology booth, a micron oil droplet separator filter from the air stream, developed by Dr. Mohammad Ali Ehtiram, a faculty member of this university, has been displayed to the public.
