1.2m, 5.2kg turbine blade fabricated entirely with cellulose and chitosan, the most ubiquitous biopolymers on earth and produced in large amounts in almost every ecosystem. Both ingredients are obtained from by-products of the industry, resulting in production with negative ecological footprint.
Researchers have recently demonstrated the use of cellulose to sustainably manufacture/fabricate large 3D objects. Their approach diverges from the common association of cellulose with green plants and is inspired by the wall of the fungus-like oomycetes, which is reproduced introducing small amounts of chitin between cellulose fibers. The resulting fungal-like adhesive material(s) (FLAM) are strong, lightweight and inexpensive, and can be molded or processed using woodworking techniques.
