Mushroom-Based Leather: What is Mylo? Features and Applications

Mylo is an innovative, sustainable leather alternative derived from mushroom mycelium, the root system of fungi. Mylo combines the power of biotechnology and design to offer an eco-friendly solution that serves as a substitute for traditional leather and synthetic materials. It was developed by the biotechnology company Bolt Threads, which has been pioneering this material to meet the growing demand for sustainable options in fashion and other industries.

Features of Mylo

Bio-Based Material
Mylo is produced using mushroom mycelium, a fibrous, thread-like network that grows underground. This material is entirely renewable and grows rapidly under controlled conditions, making it a sustainable choice for reducing dependence on animal-based and petroleum-based materials.
Sustainability
The production of Mylo requires significantly less water, energy, and land compared to traditional leather production, which is highly resource-intensive. Moreover, since it eliminates livestock farming, it drastically reduces the carbon emissions and methane output associated with conventional leather production.
Natural Appearance and Texture
Mylo has a soft, flexible texture similar to leather, with a customizable appearance. It can be dyed in various colors and treated to achieve different finishes, such as glossy or matte, making it suitable for a wide range of applications.
Vegan and Animal-Friendly
As Mylo is made entirely from plant-based materials, it offers a cruelty-free alternative for consumers who prioritize ethical consumption and seek products that do not harm animals.
Flexibility and Versatility
Mylo can be processed into varying thicknesses, densities, and textures, making it highly adaptable for diverse products. It also performs well with conventional leatherworking techniques such as cutting, sewing, and shaping, which makes it a seamless substitute for traditional leather in existing manufacturing processes.

Production Process of Mylo

Cultivation of Mycelium
Mycelium is cultivated in a sterile, controlled environment using agricultural waste like sawdust or corn husks as its primary food source. These agricultural byproducts, which might otherwise go to waste, are converted into a valuable material through the natural growth of mycelium.
Optimizing Growth Conditions
To ensure the mycelium develops into a dense, durable structure, environmental conditions like temperature, humidity, oxygen levels, and nutrient balance are carefully controlled. Under ideal conditions, the mycelium can grow into a fully formed leather-like sheet in just a few days, showcasing its efficiency as a renewable resource.
Harvesting and Pressing
Once the mycelium has grown to the desired thickness and structure, it is harvested and compressed. This pressing process enhances its density, texture, and durability, allowing it to mimic the physical properties of animal leather.
Treatment and Finishing
The harvested mycelium is treated with eco-friendly, non-toxic agents to improve its longevity, flexibility, and water resistance. Unlike traditional leather tanning, this step avoids harmful chemicals like chromium, which are highly polluting.
Dyeing and Customization
Eco-friendly dyes and finishes are applied to achieve the desired appearance and texture. The material can be embossed or patterned to resemble natural leather grains or customized for specific aesthetic requirements.
Final Testing
Before being used in products, Mylo undergoes rigorous quality testing to ensure it meets industry standards for durability, elasticity, and performance.

Applications of Mylo

Fashion and Textile Industry
- Footwear: Brands like Adidas have incorporated Mylo into eco-friendly sneaker designs, demonstrating its potential in high-performance, sustainable footwear.
- Accessories: Mylo is widely used in vegan handbags, wallets, and other accessories, offering the durability and premium feel of leather without ethical concerns.
- Apparel: Designers are increasingly using Mylo for jackets, skirts, and pants, embracing its flexibility and customizability.
Furniture and Home Decor
Mylo's durability and aesthetic appeal make it ideal for furniture upholstery, cushion covers, and other interior decor applications. Its ability to be customized for color and texture allows it to blend seamlessly into modern, eco-conscious designs.
Automotive Industry
The automotive sector is exploring Mylo for interior applications such as seat upholstery, steering wheel covers, and dashboard trims. Mylo provides an ethical and sustainable alternative to leather without compromising on style or durability.
Technology Accessories
Tech companies have started utilizing Mylo for products like laptop sleeves, phone cases, and wearable device bands, combining style and sustainability in these highly functional items.

Advantages of Mylo

Eco-Friendly:
Mylo is produced using renewable agricultural waste and emits significantly less carbon during production compared to livestock-based leather. It also uses much less water and energy than conventional leather production.
Ethical and Vegan:
As a plant-based material, Mylo is cruelty-free and caters to vegan consumers and businesses seeking sustainable alternatives to animal-derived products.
Biodegradable:
Mylo has the potential to biodegrade under the right conditions, unlike synthetic leather, which often contains non-biodegradable plastics.
Customizability and Versatility:
Mylo offers extensive options for customization, from color to texture, making it suitable for a wide range of industries and design needs.

Environmental Impact

Compared to traditional leather production, Mylo has a significantly reduced environmental footprint:

Reduced Carbon Emissions: Mylo production generates far fewer greenhouse gases than livestock farming.
Lower Water Usage: Traditional leather production often requires massive amounts of water for animal farming and tanning. Mylo's production, by contrast, is water-efficient.
No Microplastics: Unlike synthetic leather made from petroleum-based plastics, Mylo is free from microplastics, further enhancing its eco-friendly credentials.

However, it’s worth noting that the binders and coatings used during production may include synthetic elements, which could limit its biodegradability. Continuous research is underway to replace these components with more sustainable alternatives.

Conclusion

Mylo is a groundbreaking innovation at the intersection of biotechnology and sustainability. Its versatility and eco-friendly production process make it an ideal alternative to traditional leather, catering to industries such as fashion, automotive, and home decor. By prioritizing renewable resources and ethical manufacturing practices, Mylo represents a significant step forward in creating sustainable materials for a greener future.
