Typha, commonly known as reed, cattail or bulrush, is a fast growing plant that flourishes in the watery areas of Friesland in the Netherlands. In collaboration with ‘BetterWetter’ initiative of the municipality Dantumadiel, ecological consultancy firm A&W, knowledge workshop North East Frisia, Dijkstra Draisma and Studio Tjeerd Veenhoven, a regional value chain is being developed to turn typha into insulation material. Studio Tjeerd Veenhoven is developing insulation suitable for cavity walls that meets the current building standards.

The aim is to make the Life Cycle Assessment (LCA) as sustainable as possible. They strive for low CO2 emissions and low energy use, and avoid the use of harmful substances, by harvesting, producing and applying the value chain locally.
