Biomanufactured materials refer to the production of high-performance materials such as spider silk and leather alternatives through the use of engineered organisms like microbes or fungi. These materials are grown rather than extracted from natural sources or synthesized using petrochemicals.
The technology addresses environmental concerns related to petrochemical-based manufacturing and animal agriculture by providing sustainable alternatives that require less energy, water, and land while producing materials with similar or superior performance characteristics.
Engineered microorganisms, typically bacteria or yeast, are modified to produce specific proteins that can be spun into fibers or used as a base for creating materials. Alternatively, fungal mats are cultivated and processed into leather-like sheets. These processes occur at the pilot scale, allowing for initial testing and optimization before full-scale production.
Pilot-scale biomanufacturing involves setting up controlled environments where engineered organisms are cultured under optimal conditions. The secreted proteins are then harvested, processed, and transformed into final products such as fibers or sheets.
The build process includes genetic engineering of microorganisms to produce specific proteins, fermentation in large tanks to grow the organisms, protein extraction from the culture medium, purification, spinning into fibers, and finishing processes for material formation.
