Emma Sicher's Biomaterial Innovations: Cultivating the Future of Sustainable Design










Emma Sicher, a Berlin-based biodesigner, is spearheading innovative material development by harnessing the power of microbial growth. Her research centers on cultivating bacteria and yeast to produce microbial cellulose, a versatile substance she transforms into a diverse range of items. From delicate, transparent packaging to novel edible food concepts, Sicher's creations exhibit an extraordinary spectrum of hues and tactile qualities, all achieved through the natural process of fermentation. This biological transformation allows microorganisms to actively contribute to the material's inherent characteristics.
Central to Sicher's methodology is the utilization of SCOBY, a symbiotic culture of bacteria and yeast often recognized from kombucha production. As these microbial communities flourish within a nutrient-rich liquid, cellulose-generating bacteria form a gelatinous film on the surface. This film can then be harvested and further processed into flexible sheets or molded into various shapes for both culinary and material applications. In her 'EATING SCOBY' initiative, Sicher delves into the gastronomic potential of this cellulose-rich membrane. Collaborating with food microbiologists and consulting with culinary experts, she has developed prototypes such as SCOBY chips, offering a satisfying crunch that transitions to a chewy, jelly-like consistency, and an inventive ice cream cone that could feature a melted chocolate lining. Her double-flavored popsicles, reminiscent of blended aloe vera, aim to introduce this unusual ingredient into familiar food formats, expanding our perceptions of texture and presentation while exploring its role in future food systems.
Sicher's commitment to sustainable design began with her 2017 project, 'From Peel to Peel', which focused on creating biodegradable food packaging from discarded fruit and vegetable waste. Apple peels and beetroot scraps served as nourishment for microbial cultures, resulting in thin, wrappable sheets and small containers. The final product's color varied based on the initial ingredients, from soft yellows to vibrant pinks. Although the material's moisture absorption limits its use for conventional wet food packaging, this project laid the groundwork for Sicher's ongoing approach: allowing natural biological processes to dictate a material's properties from its inception. Moving forward, Sicher has investigated growing materials using local microorganisms. Her 2026 research involved utilizing Berlin's foraged rowan berries and Brandenburg's mirabelle plums to successfully produce cellulose membranes through fermentation, bypassing traditional kombucha starter cultures. These experiments, coupled with insights from Thai fermentation practices, highlight how regional flora and microbial populations can introduce unique biological variations into cultivated materials, a level of specificity challenging to replicate through standardized manufacturing.
Through her work, Emma Sicher emphasizes a collaborative design approach where living organisms are active partners in creation. Her workshops, such as those at Elisava School of Design and Engineering, empower participants to cultivate their own SCOBY membranes and explore the transformative effects of processing on cellulose. By thoughtfully selecting plant inputs and optimizing the growth environment, Sicher guides the microbial process, yet acknowledges the autonomous role of microorganisms in shaping the final material. This symbiotic relationship between human intention and natural biological interactions offers a compelling vision for a future where ecological principles are intricately woven into the fabric of design, leading to innovative and harmonious solutions for both consumption and environmental stewardship.
