Abstract: Building with renewable resources is constantly gaining in significance throughout our society. However, the question arises, if the building materials made from renewable resources are indeed sustainable. The “Deutsche Bundesstiftung Umwelt” (German Environmental Federal Foundation) funded from 2005 to 2007 the project “Development of a complete biogenous insulating material”. The objective of this project was to develop a 100 % biogenous and biodegradable hemp insulating material. Therefore, during the course of the project, bicomponentpolyester supporting fibers made of fossil resources in the hemp insulating material should be replaced by biogenous polymers with biodegradable characteristics. Apart from the technical development of this insulating material, its sustainability was examined with the method of Life Cycle Assessment (LCA). Within the project the new insulating material could be successfully found. Furthermore, the existing production process for the conventional product as well as the process for the new developed product could be optimised in order to reach a better environmental performance. In the end, the new developed insulating material shows in certain impact categories advantages compared to the hemp insulating material with conventional supporting fibre. The presentation will show and interpret the results regarding the environmental performance of the new developed hemp insulating material compared to the conventional hemp insulating material.
