Biofabricated Leather
Biofabricated leathers are leather-like materials grown or engineered using biological processes—such as mycelium, bacteria, or plant structures—rather than derived from animal hides.
Leather alternatives historically relied on plastics (PVC, PU), trading animal welfare for fossil fuel dependence. Biofabricated leather represents a third paradigm: grown materials rather than extracted or synthesized.
Scientific groundwork emerged in biotechnology labs in the early 2000s, but fashion adoption accelerated in the 2010s as climate and animal-rights concerns converged. Mycelium research—using fungal root structures—proved especially promising due to rapid growth and low resource input.
Luxury fashion played a critical role in legitimization. Karl Lagerfeld publicly supported non-animal innovations late in his career, while Stella McCartney pioneered commercial partnerships using Mylo™, a mycelium-based leather alternative.
Cactus-based materials (notably from Mexico) further expanded definitions of “leather,” challenging Eurocentric material hierarchies. In particular, Mexican innovators have been pivotal in developing cactus-derived leather alternatives that use significantly less water and land compared to traditional cattle ranching.
Biofabricated leather occupies a symbolic space where technology meets ethics. It appeals to futurism, cruelty-free values, and luxury experimentation. Unlike vegan leather of the past, these materials emphasize biology over plastic, reframing sustainability narratives.
Culturally, they also challenge craftsmanship myths: if leather can be grown, what defines authenticity? Designers increasingly celebrate lab processes as a new form of artisanal skill.
The rise of biofabricated leather aligns with growing global trends towards sustainability and ethical consumerism. Countries with strong animal rights philosophies, such as Germany and Sweden, have seen increased interest in biofabrication as a method to lead ethical consumption practices.
Pop culture reflects this shift as well, with movies and shows often depicting futuristic societies using bioengineered materials, subtly influencing societal perceptions on what can be considered high-quality or luxurious.
– Mycelium leather can be grown into molds.
– Some cactus leathers still contain PU layers.
– Biofabrication allows texture customization at the growth stage.

2018 marked the entry of mycelium as a serious contender within the fashion landscape, as brands began exploring its potential for creating leather alternatives that merged sustainability with luxury appeal. This trend gained momentum with luxury brand pilots announced in 2020, showcasing the market’s openness to environmentally friendly innovations.
From 2021 to 2023, biofabricated leather became a regular feature in sustainability headlines, mirroring increasing consumer demand for eco-conscious products. The discussion transcended niche markets, with more prominent figures in fashion advocating for its wider adoption.
However, the period of 2024 to 2025 is expected to bring a focus on overcoming scaling challenges. While the technology itself showcases potential, the transition from experimental to widespread usage will heavily rely on innovation in enhancing durability and affordability.
Specific investment rounds, partnerships, and new product launches by key players such as Adidas (Mylo-based sneakers) represent turning points within this timeline, offering a snapshot of the industry’s direction towards integrating biofabrication into mainstream production.
Future discussions anticipate a deeper exploration of the purity and performance of biofabricated leathers, emphasizing the necessity for materials that are not only eco-friendly but also able to withstand the practical demands of everyday use.
Biofabricated leathers dramatically reduce land use, water consumption, and methane emissions compared to animal leather. Mycelium can grow in days rather than years, while cactus leather uses minimal irrigation.
However, scalability remains the key challenge. Many materials still rely on polymer backings for durability, complicating biodegradability claims. The most promising developments focus on fully bio-based composites.
Practical applications include accessories, footwear uppers, and interiors—areas where durability requirements can be controlled.
Mycelium Leather (Fungal-Based)
Grown from mycelium, the root-like network of fungi. Mycelium is cultivated in controlled environments, then compressed, tanned, and finished to resemble animal leather.
Key innovators
- Mylo™ (Bolt Threads)
- Reishi™ (MycoWorks)
Who is using it
- Stella McCartney – garments and accessories using Mylo
- Hermès – Victoria bag made with MycoWorks’ Reishi
- Adidas – Mylo-based sneaker prototypes
- Lululemon – early Mylo pilots
- Kering – investment and material trials
Status
Most advanced biofabricated leather type, but scaling remains limited and many versions still use polymer backings.
Bacterial Cellulose Leather
What it is
Produced by bacteria fermenting sugars, creating dense cellulose sheets (often called SCOBY or kombucha leather). It is grown, dried, and sometimes coated for durability.
Who is using it
- Experimental designers and research labs
- Fashion education institutions (Central Saint Martins, Parsons)
- Small-scale luxury accessories and concept garments
Notable characteristics
- Fully bio-based
- Naturally translucent
- Extremely low environmental footprint
- Poor water resistance and durability without coatings
Status
Still experimental, not yet viable for mass-market fashion without hybridization.
Plant-Based Bio-Structured Leathers (Cactus, Fruit, Leaf)
What it is
Derived from plant biomass (cactus, pineapple leaves, apple pomace, grape waste), mechanically processed into leather-like sheets.
Key materials & users
- Desserto® (cactus leather)
- Used by Karl Lagerfeld, BMW interiors, Fossil
- Piñatex® (pineapple leaf fiber)
- Used by Hugo Boss, H&M Conscious
- Vegea® (grape waste)
- Used by luxury footwear and accessories brands in Italy
Important caveat
Most plant-based leathers contain polyurethane coatings for durability, meaning they are bio-based but not fully biodegradable.
Status
Commercially available and scalable, but often misclassified as fully sustainable.
Lab-Grown Collagen (Cellular Agriculture Leather)
What it is
Leather grown from animal collagen cells without raising or slaughtering animals. Structurally identical to leather but grown in labs.
Innovators
- VitroLabs
- Modern Meadow
Who is using it
- Currently not yet in consumer fashion retail
- Backed by luxury conglomerates and automotive brands
- Pilot-stage collaborations with European luxury houses (undisclosed)
Status
Technologically promising but very expensive and years away from mass adoption.
Algae-Based & Protein Polymer Leathers (Emerging)
What it is
Made from algae proteins or engineered bio-polymers, often blended with natural binders.
Who is using it
- Material science startups
- Footwear and automotive R&D labs
- Experimental runway pieces and exhibitions
Status
Early-stage, high innovation potential, low availability.
