The designers of the group have founded Re-Generacija, a platform for the further development of projects they started during BIO 50. In the context of Japanese Knotweed – A Friendly Enemy, a project that was supported by City Municipality of Ljubljana, they researched possible uses of this invasive non-native plant. Their work resulted in Japanese-knotweed-based cellulose, from which the first paper samples were made in the spring. In autumn, the project received support from the Ministry of Culture of the Republic of Slovenia, while MAO joined as producer. Together, we established a partnership with the Pulp and Paper Institute Ljubljana (ICP), the Re-Generacija Association, the Craftsman Workshop Vevče and Department of Industrial and Unique Design at the Academy of Fine Arts and Design (ALUO), and paved the way for unprecedented possibilities in the use of Japanese knotweed cellulose – in paper-making as well as for other cellulose-based products. The findings of the project are presented at the A Friendly Enemy - Japanese Knotweed in the Paper Laboratory exhibition hosted by MAO (11 December 2015 to 28 February 2016), however, we are confident that the project does not end here. We expect Japanese knotweed to be a constant source of surprise in the future.
