Quantitative sustainability assessment of bio-based materials for wind turbine rotor blades

Over the recent decades biomaterials have been successfully marketed thanks to the common perception that biomaterials and environmental sustainability de facto represent two sides of the same coin. The development of sustainable composite materials,has partially been focused on the substitution of conventional fiber materials with bio-fibers. The main unsolved issue is if this material substitution is supporting sustainable development, or leading to negative effects to burden shifting
