Cattail (Typha) and wood wool comprise the walls of the new biobased modular house that the German company Holzbau Janssen built in Werlte in August. In addition, parts of the walls contain pure wood wool, cellulose and mineral wool. The Jadehochschule Oldenburg will compare the insulation values of all these materials with sensors built into the walls of the house. The large-scale study is part of the German-Dutch EU-supported INTERREG VA project "Bio-economy - Green chemistry".

It was already clear in advance that the new materials, if properly produced and assembled, represent a significant technological and practical alternative to the products used up to now. By gaining practical experience now and collecting measurement results, the initiators hope that construction companies will choose sustainable materials more quickly in the future. The results will be presented at a later stage in the 3N Kompentenzzentrum in Werlte.

However, biobased construction is not just about insulating materials. It is also important to avoid harmful substances, such as toxic adhesives. There is also an alternative available for this with biobased glue. This glue is currently being tested by the Arnhem (The Netherlands) based company Plantics. The project also tests sustainable alternatives for the load-bearing elements in the building.
