Abstract:
A mass of studies about windmill turbine blades have been addressed in the recent few decades. This report focus on the development of using bamboo composite materials for producing windmill turbine blades related to the life cycle assessment with sustainable perspective. So we made the problem formulation like this: How can bamboo fibers be used in the design and production of wind mill blades and how would it influence the impact of wind mill blades in a lifecycle perspective? In order to answer this question, we made a research about the properties of bamboo material and made a LCA to compare the performance between bamboo turbine blades and glass fiber turbine blades with sustainable perspective. The result concluded that bamboo material fulfilled the requirement of constructing a turbine blade and has a high performance associated with sustainable development.

Key words:
LCA (life cycle assessment), Sustainable development, Bamboo wind turbine blades

Acknowledgement
Initially, we would like to express our appreciation to our main supervisor Inger Stauning and secondly supervisor Bent Søndergård in Roskilde University Center, for their valuable help and advices in our project studies. The idea of the project is from Inger Stauning, she gave us many helps. On the other hand, we also express thanks to Risø DTU. There are two persons who provided many useful data for our project, Povl Brøndsted and Peter Hjuler Jensen, especially Povl Brøndsted, many bamboo data of our project is obtained from him.
