Researchers at Rice University and the University of Houston have developed a breakthrough biofabrication method that produces ultra-strong, flexible, and transparent bacterial cellulose (BC) sheets. Using a rotational bioreactor to align cellulose fibers during growth, the team created a sustainable material that rivals metals and plastics in strength up to 553 MPa with boron nitride enhancement without environmental downsides.

This scalable, chemical free process enables real-time fiber alignment and allows for easy integration of nanoscale additives, improving thermal conductivity and mechanical performance. The resulting biopolymer is ideal for applications like flexible electronics, heat-dissipating films, biodegradable packaging, and wearable tech offering a powerful alternative to traditional plastics in the circular economy.

The process is chemical-free, energy-efficient, and works with standard incubator equipment, making it ready for industrial scaling.
