Revolutionary biomaterials
for forward thinkers.
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.
Fold Studies 01: Celium™ Is Now Available as Folded Everyday Objects
- Published on
- June 10, 2026
For the first time, finished pieces made with Celium™ Premium Cultivated Cellulose are available directly through a limited Vibe Lab Studio drop.
Fold Studies 01 brings Celium™ into everyday use through a family of folded objects developed by Vibe Lab Studio in collaboration with Polybion and PLEK. The drop is not presented as a prototype, sample, or future application, but as a limited series of objects that can be purchased, carried, touched, and used now.
The project began with a clear intention: to bring biomaterials into real, usable objects, and make them accessible beyond the lab, the studio, or the material sample.
For Polybion, this matters because material innovation does not end when a biomaterial is ready. It needs to be tested, handled, carried, and understood in real contexts. Vibe Lab Studio was created to operate in that space: translating biomaterials into limited drops that make new materials tangible today.
Fold Studies 01 explores that idea through one design principle: the fold.
Most everyday objects are built by assembling separate parts. They are cut, stitched, glued, layered, or reinforced. In this drop, the construction logic is different. Each piece starts from a continuous surface of Celium™ Premium Cultivated Cellulose and takes shape through folding.
The fold becomes the structure.
The material is grown, transformed, and folded into function.
The collaboration with PLEK brought deep knowledge of folded object construction. Together with Vibe Lab Studio and Polybion, the team explored how Celium™ could behave in compact accessories designed to be touched, opened, closed, and carried repeatedly.
The result is a family of folded essentials:
Fold Phone Bag
A compact crossbody piece designed to carry a phone and small daily objects. Its rectangular shape is formed through folding, with a flap closure, metal studs, and a chain strap.
Fold Card Wallet
A minimal folded wallet for cards and small essentials. Its compact structure is defined by the fold itself, without visible stitching or glued construction.
Fold Phone Wallet
A larger folded wallet designed to carry a phone, cards, and personal items. Its elongated format follows the same continuous-surface logic, with metal closures and an optional chain strap.
Fold Pyramid Bag
A structured geometric bag that uses folding to create volume and presence from a continuous material surface.
Fold Passport Sleeve
A folded travel essential designed to protect and carry a passport in a compact format.
Across the collection, the pieces are made with Celium™ Premium Cultivated Cellulose, recycled polyester backing material, stainless steel hardware, and aluminum chain straps where applicable.
Fold Studies 01 is organized into three color universes:
Dark Mineral
Obsidian and Basalt Bloom. A darker, mineral register that brings together a classic black surface with a more expressive black-and-white variation.
Earth / Sun-Worn
Golden Loess and Forest Core. A warmer universe that moves between dry light and deep green, placing the fold in a more grounded everyday context.
Tidal / Air
Pelagic Indigo and Natural. A lighter, softer expression of the drop, with blue surface variation and a more neutral material tone.
Together, these colors show different expressions of Celium™: dark, mineral, warm, grounded, light, and atmospheric.
Fold Studies 01 places Celium™ in circulation as something direct and usable. Not a swatch. Not a prototype. Not an idea waiting for adoption.
A material, folded into objects made to be carried now.
The limited drop is available through Vibe Lab Studio.
