On Friday, we went to Stockholm. We took the road through Östergötland and made a stop in Österbymo in order to visit the Träullit factory. Träullit is a building material made of wood wool, cement and water. This could be a suitable building material for the Congo. The factory has produced wood wool slabs since 1946. Bengt Rääf, CEO, received us at the factory. First, he showed us a film about the material, and then he gave us a tour of the factory. Then we visited a kindergarten built entirely with träullit. It was a very attractive building. Architect Torbjörn Bjerhagen had taken the initiative for our visit because he believes the material would fit the Congo. In October, he travels to Congo and he will bring the material to test it. In a year, we will know if it is resistable to termites, other insect pests and the climate in general. At the end of our visit we were treated to a tasty dinner by Bengt Rääf at the Old Homestead in Österbymo.
