Celium™
Premium Cultivated Cellulose.
We grow Celium™ by feeding bacteria with agro-industrial fruit waste.
Rooted in biology
Guided by design
Refined into Celium™
Celium™ is a new generation of cultivated materials.
Grown by bacteria nourished with agro-industrial fruit waste, it forms during fermentation as a cultivated sheet of cellulose. This biological origin gives Celium™ a coherent structure that is resilient, soft, and inherently adaptable.
After cultivation, the material undergoes a stabilization process that defines its characteristics. During this stage (our equivalent to tanning), we refine thickness, handfeel, flexibility, and overall performance. Once stabilized, Celium™ can be finished through color, embossing, or protective finishing, extending its visual and functional possibilities while preserving its biological foundation.
Celium™ does not imitate existing materials; it stands as a category of its own. Each sheet carries subtle variations linked to its living origin, resulting in a refined, high-performance material capable of adapting across applications. Cultivated with precision and shaped through intention, Celium™ reflects a new approach to making: one that begins with life and evolves through design.
One material, multiple expressions
Performance Meets Possibility
One cultivated material can take on many roles. Celium™ begins as a cultivated sheet of bacterial cellulose, but its behavior is defined in the hands of designers and makers. It can drape, fold, and stitch like a soft surface, or be structured into precise, architectural forms. The same origin can become a garment panel, a bag shell, a lighting element, or a piece of furniture detailing.
Its versatility comes from how it responds to transformation. Celium™ can be cut cleanly, layered, perforated, embossed, or combined with other substrates to adjust body and support. Surface finishes introduce color, protection, and texture without erasing the material’s depth. This combination of responsiveness and stability makes it suitable for both tactile, close-to-skin pieces and more robust, spatial applications.
Across these uses, Celium™ maintains a coherent identity: a cultivated material with a refined hand, visual definition, and a clear link back to its biological origin. Rather than mimicking existing materials, it gives designers a single, consistent base they can push in multiple directions, exploring new expressions without changing the underlying source.
Where biology meets creativity, the future unfolds.
How to Work with Celium™
Celium™ is available in full sheets, sample kits, or through custom developments. Brands, studios, and independent designers can request materials directly from our team by filling out the inquiry form or contacting orders@polybion.bio.
Each request begins with a short conversation. We help identify the most suitable version of Celium™, discuss quantities, finishing, and timelines, and offer tailored guidance for your intended application. For small developments, the minimum order is two sheets of 17 sq.ft. each, ideal for prototyping. For customized color or material characteristics, the minimum order is 63 sheets. For pricing, please contact our team.
Celium™ is grown to order. Although our production is fully scaled, cultivation happens batch by batch, which means we operate through a delivery pipeline and often work with a waiting list. Once your order enters production, we coordinate cultivation, finishing, and shipment from our headquarters in Mexico to any destination worldwide.
Celium™ is cultivated with care, and so is every collaboration that begins with it.
Growing Celium™ at a New Scale

At Polybion™, every new scale changes the way we understand the material.
We recently reached a milestone that would have seemed nearly impossible only a few years ago: growing what we believe to be the world’s largest continuous sheet of bacterial cellulose.
This is not an exhibition piece or a speculative prototype, it is part of a special development for a global company, requiring us to work with Celium™ at a scale we had not previously achieved.
Increasing the size of a cultivated material is not simply a matter of using a larger production surface. Every increase introduces new challenges across cultivation, handling, consistency, drying, and transformation. Conditions must remain controlled throughout the entire sheet, while the material must retain the properties required for its intended application.
Solving these challenges helps us understand Celium™ more deeply. It allows our team to refine the processes behind its production, identify new technical limits, and expand the range of applications that can be developed with Premium Cultivated Cellulose.
This milestone also arrives at a complex moment for the biomaterials industry. Funding has declined, brand support has become more limited, and much of the attention that once surrounded alternative materials has moved elsewhere.
But material development does not follow attention cycles.
It continues through long-term technical work, industrial discipline, collaboration, and teams willing to keep solving the challenges that emerge between an idea and its real-world implementation.
At Polybion™, we remain focused on that work: cultivating, learning, scaling, and building the manufacturing capabilities required to move biomaterials beyond experimentation.
This sheet represents an important technical achievement, but it is not an endpoint. It is further evidence that we are still far from reaching the limits of what bacterial cellulose—and Celium™—can become.
