SCOBY-Based Biomaterials for Sustainable Generative Design and Architecture

Introduction

Home brewers are familiar with the need to dispose of excess SCOBYs they peel off from multiple ferments. Some embrace Hannah Crum’s recipe for SCOBY Fruit Leather. Others feed the pellicles to their pets. Commercial brewers face this challenge on a far larger scale. Recycling the material for composting or natural gas production are the more environmentally friendly options.

But what about the potential for SCOBY pellicles to go beyond fruit, Fido, or fertilizer?

From pictures of Sacha Laurin’s award-winning SCOBY fabric designs featured in the Fall 2021 edition of SYMBIOSIS Magazine, to the Imperial College, London research on vegan leather production, and Shajia Meraj’s art inquiring into grief, memory, and circularity, people are experimenting with creative uses for the pellicle.

A new research paper, From Kombucha to Architecture: Transforming SCOBY into a Sustainable Biomaterial for Generative Design Solutions, by Curro Polo and José Antonio Carrillo Andrada, was published July 2, 2026, by Springer following the SCIN 2025 conference (Sustainable Creative Art: Inspiration from Nature). These scientists, associated with the American University in Dubai and Harvard University, set out to explore the question: can bacterial cellulose grown from kombucha SCOBY meet the mechanical and environmental demands of design applications, from small culinary objects to furniture and architectural skins? The result is a bridge: from materials grown through the living process of fermentation, into a computational design environment, and from there toward architecture.

Their research outlines a pioneering interdisciplinary framework that bridges food science, architecture, and computational design to transform bacterial cellulose (BC) harvested from kombucha SCOBY into a high-performance, sustainable biomaterial. They describe in detail the production methods employed, including creative ways to improve malleability, share creative AI-generated images, and employ tools to productize these. The study demonstrates that BC can meet mechanical and environmental requirements for applications ranging from biodegradable culinary artifacts to architectural skins.

Key findings indicate that BC possesses superior industrial properties compared to plant-based cellulose (PC), including higher purity and water retention. Mechanical testing reveals that the material is highly sensitive to humidity, a characteristic that allows it to function as a “responsive agent” in design.

The research establishes a reproducible “software–wetware–hardware” pipeline that aligns with the United Nations Sustainable Development Goals (SDGs) 11 and 12 by promoting closed-loop production, waste reduction, and the use of locally sourced, compostable building materials that help “make cities and human settlements inclusive, safe, resilient and sustainable.”

The SCOBY in a post-anthropocentric world

Just as Pakistani student Meraj celebrated the SCOBY as a time-based medium that responds to its environment and the care it receives, so Carrillo and Pollo adopted a post-anthropocentric paradigm, viewing SCOBY-BC as a “co-designer” rather than a passive resource. The material’s natural behaviors—such as shrinking, thickening, and patinating over time—are embraced as design drivers. This shift from permanence to ephemerality enables “soil-positive disposal,” in which architectural and culinary artifacts reintegrate into ecosystems at the end of their lifecycles.

They blend scientific rigor with an artistic approach that “thrives on intuition, distorting reality to enhance the human experience.” In a passage worth quoting at length from Section 5, “SCOBY in the Post-anthropocentric World,” they state:

The post-anthropocentric paradigm challenges the dominant notion of human supremacy over nature, advocating instead for a model of co-design and interdependence with nonhuman agents. This framework values all forms of life and their interconnected systems, situating environmental and nonhuman well-being as integral to design ethics and sustainability.

Within this context, SCOBY’s derived cellulose emerges not simply as a material but as a responsive and evolving agent. Its self-assembling behavior, sensitivity to humidity and growth-dependent mechanical properties … suggest a material that behaves dynamically rather than passively. These characteristics align with Scarpitti and Valsecchi’s (2023) notion of biomaterials possessing intrinsic value beyond utility, forming part of a living, co-creative design system.

The boundary-crossing nature of SCOBY, between the living and non-living, is evident in both its biological variability and design responsiveness. In our study, changes in environmental conditions directly altered SCOBY’s BC tensile performance and biodegradability. This supports a design approach where material behavior itself becomes a driver, not just a constraint. These observations resonate with bio-art principles (Carrillo Andrada et al., 2024), where living materials are not controlled but engaged as collaborators in both aesthetic and scientific exploration.

The paper explores the artistic possibilities of the SCOBY by presenting a number of Midjourney images.

Picture this

Images were generated with Midjourney prompts to enable “conceptual ideation to functional prototypes that range from cutlery and packaging to building facades, pop-up restaurants and interior partitions.” These range from ‘low-value food-grade by-products’ (UN SDG 12)

to the architectural design of buildings with ‘compostable skins that reduce the environmental impact of cities’ (UN SDG 11)

These images inspired me to imagine the fermented dome of a future Martian colony, and to speculate about extraterrestrial fermentation that I introduced in Episode 12 of ‘Our Fermented Future‘, anticipating a time when “In the silent vacuum of the cosmos, the gentle bubbling of fermentation tanks became the heartbeat of life.”

/Imagine A lightweight, opaque SCOBY-based building facade design with an organic texture suitable for terraforming domes that could be used when colonizing planets such as Mars. Emphasize structural integrity, with a sample of a dome surface inspired by natural fermentation patterns. –ar 16:9 –v 6.1

The field of dreams: From design to prototypes

The paper suggests that these images can be fabricated with the help visual scripting tools such as Grasshopper 3D:

Each selected Midjourney frame is rebuilt in a single Grasshopper script that automatically imposes mechanical limits such as sheet thickness, minimum bend radius and panel size. If any curve tightens beyond the experimentally verified radius, the model flags itself “not fabricable”; otherwise, it exports watertight geometry together with the original Midjourney seed and prompt ID. These data are later assessed in Karamba 3D, a parametric structural engineering plugin for Grasshopper that enables interactive analysis and optimization of load-bearing structures.

The result? “Once a design passes simulation, physical realization will follow.” Build it, and they will come, eh lads?

    The Register reports that researchers from The Hong Kong University of Science and Technology and The Hong Kong Polytechnic University have published a paper describing how Mars astronauts could live in houses made of yeast and jello.

    If humans ever make it to Mars – and that’s still a big IF – they will need to build shelters there. And they could build those shelters out of yeast and gelatin, if a method described by Hong Kong-based researchers makes it out of the lab.

    A paper published on Thursday by a group of researchers from The Hong Kong University of Science and Technology and The Hong Kong Polytechnic University describes a method for building structures on Mars that doesn’t rely on energy-intensive heating to turn regolith into building blocks. The team instead turned to bioengineered yeast and gelatin mixed with simulated Mars dirt to 3D print structures.

    “My inspiration came from freeze-dried fruits that become harder,” senior author Jishen Qiu, an associate professor at The Hong Kong University of Science and Technology, told Cell Press, the publisher of the paper.

    Qiu’s idea is a relatively simple one once you break it down: Take one part yeast bioengineered to produce adhesive proteins that bind the components. Combine with artificial gelatin hydrosol to serve as a growth medium for the yeast. Add plain old Martian dirt, and extrude the material through a 3D-printing nozzle.

    If everything works as intended, the recipe should create a foamy substance that, when exposed to the dry, cold Martian atmosphere, essentially freeze-dries. As the ice sublimates into vapor, you should be left with a light, porous, but incredibly strong material. According to the researchers, that’s exactly what they got.

    “The hardened material achieved mean compressive and flexural strengths of approximately 12 and 6 MPa, respectively,” the team said. For reference, that’s roughly the same strength as low-grade terrestrial concrete. As an added perk, the team noted, the energy demand is one to two orders of magnitude lower than that of heat-processing Martian (or lunar, for that matter) dirt into building material.

    According to the paper, the material can be broken down and reused too – provided at least a single yeast cell survives the process, and the cold, barren wasteland of Mars, that is. The team isn’t sure that would necessarily be the case, but nothing is stopping Martian yeast masters from keeping a supply on hand for future projects just in case.

    The structures they built and tested in their simulated Martian conditions were tiny little beehive-shaped things, measuring just 45 mm tall (a little under 2 inches).

    “Is there any physical law or fundamental mechanism that prevents us from doing this?” Qiu asks of his work. “I can’t see any at this point in time.”

    Qiu said his team is confident that it can scale the tech, but that’s not the only thing that needs to be tested more fully. Per the paper, testing the ability of the yeast-gelatin building foam to retain the pressure necessary to keep humans from succumbing to the Martian elements was outside the scope of the research.

    “A practical lunar or Martian habitat must integrate pressure retention, gas tightness, mechanical support, thermal regulation, radiation shielding, dust protection, repairability, and resource recycling,” the paper notes. “These requirements will likely require hybrid architectures” that include both the yeast foam and more traditional structures.

    Either way, avoiding the need to heat Martian dirt could reduce the energy and heavy equipment required to build structures there. That’ll be important if we ever actually want to get to Mars. But if we get there, at least we’ll have yeast.
