Breakthrough Mushroom Leather Could Transform Sustainable Fashion
Researchers in Finland have developed a scalable way to manufacture a leather-like material from mycelium—the branching network of microscopic fibers produced by fungi.
The experimental fabric can be cut, dyed and sewn. It also achieved promising tensile strength in laboratory tests and rapidly disintegrated under controlled industrial composting conditions.
Just as importantly, the researchers demonstrated a continuous production process rather than making only small, individually grown samples. That step could help move mushroom leather closer to commercially useful manufacturing.
Key facts
- The material is made using mycelium from the fungus Trichoderma reesei.
- Researchers cultivated the fungus in liquid-filled bioreactors.
- Cellulose fibers reinforced the material, while a plasticizer improved flexibility.
- Test sheets reached tensile strengths of 11–19 megapascals.
- A continuous system produced an eight-metre-long sheet.
- Researchers used the material to make a prototype handbag.
- Tear resistance still needs improvement before widespread commercial use.
The results were published in the peer-reviewed journal ACS Applied Bio Materials by researchers associated with Finland’s VTT Technical Research Centre.
Why conventional leather alternatives remain problematic
Animal leather is valued for its strength, appearance and long service life. Its production, however, is connected to livestock farming and resource-intensive processing. The environmental impact varies considerably according to farming practices, tannery technology, energy sources and how impacts are allocated between meat and hides.
Many products marketed as vegan leather avoid animal hides but contain polyurethane, polyvinyl chloride or other fossil-derived components. These materials can be difficult to recycle, and calling them “vegan” does not automatically make them biodegradable or environmentally preferable.
Mushroom leather could occupy the space between these options: a material made primarily from renewable biological resources but designed to perform more like a conventional textile.
Its overall environmental advantage will still need to be demonstrated through complete life-cycle assessments at commercial scale.
Growing fungal fibers inside bioreactors
Many earlier mycelium materials were grown as flat sheets inside trays. The fungus expanded through a solid substrate until its fibers formed a connected layer.
Although this approach can produce useful materials, tray-based cultivation limits sheet dimensions and can make continuous, high-volume production difficult.
The Finnish research team instead cultivated Trichoderma reesei through submerged fermentation. In this process, the fungus grows inside a nutrient-rich liquid held in a bioreactor, similar in principle to fermentation systems already used by biotechnology, food and pharmaceutical manufacturers.
Rather than producing a finished sheet inside the vessel, the fungus forms a fibrous biomass that can be harvested and processed like pulp.
That separation of cultivation from sheet formation is one of the method’s most important features. Manufacturers could grow the raw material in tanks and subsequently shape it using continuous equipment.
How mushroom leather is made
After cultivation, the researchers collected and washed the fungal biomass. They then processed it and combined it with nanofibrillated cellulose and plasticizers.
The cellulose acts as reinforcement. Its fine plant-derived fibers help strengthen the network created by the mycelium. The plasticizer prevents the dried material from becoming excessively rigid or brittle.
The resulting mixture can be spread into a thin layer and dried to create a nonwoven sheet. Because the material is formed after the fungus has been cultivated, manufacturers may have greater control over its thickness, texture, color and composition.
The study also explored finishing options and the possibility of applying the material to cotton fabric.
From laboratory samples to an eight-metre roll
Producing a convincing sample by hand does not prove that a biomaterial can be manufactured economically. The researchers therefore tested a continuous roll-to-roll concept inspired by equipment used in papermaking and printing.
The pilot system produced a sheet approximately 20 centimetres wide and eight metres long.
This is not yet full industrial production. However, it demonstrates that the fungal pulp can pass through a continuous sheet-forming process instead of depending entirely on small molds or individual cultivation trays.
To show that the sheet could be handled as a textile, the team dyed and stitched it into a prototype handbag.
How strong is the experimental material?
Depending on pretreatment and formulation, the mycelium sheets recorded ultimate tensile strengths of 11–19 megapascals and fracture strains of approximately 9–10%.
The American Chemical Society described the tensile performance as comparable to conventional leather. Such comparisons should nevertheless be treated cautiously because leather properties vary by animal source, thickness, tanning process and test method.
Tensile strength is also only one measure of real-world performance. A material intended for shoes, bags or clothing must withstand repeated bending, surface abrasion, moisture and tearing around seams.
The researchers acknowledge that tear resistance remains a weakness. Until that and other durability requirements are resolved, the material should be considered a promising prototype rather than a market-ready leather replacement.
What the biodegradation tests showed
Samples biodegraded in an aquatic test environment within 28 days. In a separate industrial composting test, the material showed rapid disintegration and was completely disintegrated after approximately one and a half months.
These findings do not mean that a future mushroom leather handbag would safely disappear in any natural setting. Disintegration and biodegradation are related but distinct measurements, and industrial composting provides controlled conditions that are not necessarily available in household compost.
Commercial products may also require coatings, dyes or water-resistant finishes. Those additions could change their end-of-life behavior and must be evaluated with the complete product. Mushroom leather
Could mushroom leather replace animal and synthetic leather?
The technology addresses an important manufacturing bottleneck: producing fungal material continuously using equipment similar to systems already operating in biotechnology and paper manufacturing.
Several challenges remain:
- Tear and abrasion resistance must improve.
- Water resistance and long-term aging require further testing.
- Production costs need to be demonstrated at commercial volume.
- Any coating or finish should be included in biodegradability testing.
- Independent life-cycle studies are needed to compare the material fairly with animal leather and plastic-based alternatives.
For these reasons, mushroom leather is unlikely to replace every type of leather immediately. Accessories, decorative panels and selected fashion applications may offer more realistic entry points than products exposed to severe wear.
The research nevertheless shows that mycelium can be treated as an industrial fiber source rather than merely grown into small molded objects. If manufacturers can preserve its environmental benefits while improving durability, fungal textiles could become a meaningful part of the next generation of lower-impact materials.
Frequently asked questions
Is mushroom leather made from mushrooms?
It is made from mycelium, the branching network of fungal fibers associated with fungi. The study used Trichoderma reesei, rather than the mushroom caps normally sold as food.
Is this mushroom leather plastic-free?
The experimental formulation used fungal biomass, nanofibrillated cellulose and plasticizers, including sorbitol in tested formulations. Future commercial products would need transparent ingredient and coating disclosures before every version could be described as plastic-free.
Is mushroom leather commercially available?
Some companies have introduced mycelium-based materials and limited products, but the specific VTT material described in this study remains under development.
Can it be composted at home?
The study reported rapid disintegration under industrial composting conditions. It did not establish that a finished consumer product would fully biodegrade in ordinary home compost.
What must improve before it reaches stores?
Tear resistance is a principal limitation. Manufacturers must also validate abrasion resistance, moisture performance, aging, cost and the environmental effects of dyes and protective finishes.
