ACCIONA plans to increase its competitive advantage using nano-structured bio-based composites materials as alternatives to conventional materials, like Steel and concrete, in Civil Infrastructure applications, for example construction of bridges. Usage of bio-based materials will help ACCIONA lower its construction cost owing to faster production due to their low curing time, reduce transportation and installation time, thanks to their light weight, and reduce maintenance cost owing to their high corrosión resistance. To achieve this, isocyanate free TPU biopolymers reinforced with NL, biochar and NFC will be used for the construction of a footbridge module (2m x 0.45m x 0.65m) with 3D printing technology. The final product is expected to have high UV and fire resistance >80ºC, anti-fouling & easy-cleaning capability
