Technologisch Gezelschap Technologisch Gezelschap (TG) is the study association for Chemical Engineering studies at Delft University of Technology. These include the bachelor Molecular Science & Technology and the master Chemical Engineering. With more than 800 members TG is the biggest Chemical Engineering study association in the Netherlands. The foundation in 1890 makes TG one of the oldest study associations in the world. Ever since TG looks after the interests of his students, this means keeping a keen eye on the level of education and trying to help and improve subjects where possible. Next to that, the "Gezelschap" organizes all kinds of activities for her members each year, ranging from one-day excursions to three week intercontinental trips, lectures, symposia, a freshmen's weekend and a career fair: De Delftse Bedrijvendagen. All activities are meant to bring students in contact with the industry.
