As part of the Queima Das Fitas do Porto festival a plastic recycled pop up bar was used. The pop up bar is made from recycled materials including the blue tubing material mostly used in construction projects.
The Queima das Fitas (Portuguese for Burning of the Ribbons) is a traditional festivity of the students of some Portuguese universities, organized originally by the students of the University of Coimbra.
It was a self-standing outdoor structure that people walked up to and ordered drinks from. Very cool and very earth friendly of the festival organizers.
