On Department of Wood Science and Technology on Biotechnical Faculty (University of Ljubljana) and Trajna (product design) we produced first prototypes of wooden frame of Invasive Alien Plant Species (IAPS) - tree-of-heaven (Ailanthus altissima).

Future users will be able to create frame themselves - wooden profiles will be connected with elastic. The frame is easy to assemble and can be made in any size. Workshops for future users will be organised probably in Autumn.
