We tested which material the partners appreciate during exhibition participation. For example, Iris tested a self-running PowerPoint and printed flyers at the trade fair next door. The aim is to raise awareness of the RECLAIM project and to encourage visitors to sign up for the e-mail newsletter. The choice was made for a self-rotating PowerPoint and not for a traditional roll banner. First, everyone is using online screens these days. Secondly, roller banners are relatively environmentally unfriendly. They are often only used a few times and the material (a combination of metal pieces and plastic or polyester cloth) is difficult to recycle.
