Creating sustainable and flexible architectural skin with microbial cellulose-based material: synthesis and mechanical characterization

Abstract Attaining sustainability by developing efficient architectural materials will be a suitable remedy for various environmental problems. Incorporating clean biotechnology, particularly Bacterial Cellulose (BC), into the field of Architecture Design offers a novel strategy with the objective of creating environmentally-friendly architectural materials. The key goal of this research is to investigate the synthesis of BC by cultivating kombucha SCOBY in a culture medium that has been supplemented with sugar and tea extract. The linear density, tensile strength and strain of the BC bio-film and BC composites were assessed in order to determine the material’s degree of fitness in potential applications. The tensile test showed that BC bio-film and its jute composite had tensile strengths of 5 MPa and 10 MPa respectively, indicating notable resilience and durability as a feasible substitute for conventional construction materials. The study delves deeper into the sustainability, biodegradability, and economic feasibility of BC, emphasising its potential as an independent foundational material. The incorporation of jute fibres into BC enhances its capabilities, resulting in the development of a novel composite material known as BC + jute. This composite exhibits superior mechanical and psychochemical characteristics, making it suitable for the creation of sophisticated architectural prototypes. The results of this research establish a strong foundation for the advancement of ecologically conscious architectural solutions, demonstrating the feasibility and capacity of BC in promoting sustainability within the construction sector.Keywords: Microbial Cellulose, Scopy, Architecture, Environmental-friendly, sustainability, interior design, jute fiber, biomaterials.
