Mycelium, the root-like network fungi grow through soil and waste, is moving from novelty to a practical manufacturing material. Grown from agricultural by-products, it can become compostable packaging, leather alternatives, and high-protein food, then be composted back into the earth. Companies are now scaling it, though durability, cost, and consistency remain unsolved.
What is mycelium, and why does it matter?
Mycelium can be grown, shaped, used, and then returned to the ground. That full-circle quality is what makes it interesting: you grow the material from agricultural by-products, use it, and compost it, which positions it as a credible alternative to plastics, animal leather, and resource-heavy ingredients. From food to leather to packaging, fungal tech is scaling faster than most people assume.
Which companies are scaling it?
Ecovative turns agricultural waste into compostable packaging and leather-like materials through its MycoComposite and Forager platforms the same organism, grown in different ways, becomes protective packaging in one process and a leather substitute in another.
Maia Farms develops mycelium-based food ingredients aimed at clean-label, high-protein functionality, and reports recent funding that signals momentum in fungal food tech.
MycoWorks produces Reishi, a fine-mycelium biomaterial the company compares to animal leather.
In September 2023 it began production at the world’s first commercial-scale Fine Mycelium plant in Union, South Carolina the step most material startups struggle to reach (MycoWorks / PR Newswire, 2023).
As alternative proteins and sustainable materials gain momentum, the innovation occurring in mycelium-based products reflects broader changes taking place across the global food system.

What are the honest trade-offs?
The benefits are real: lower carbon footprints, biodegradability, and productive use of agricultural waste that would otherwise be discarded. So are the challenges. Durability, cost, and the difficulty of growing consistent material at scale are the open problems, and none of them are solved yet.
The useful way to read this is as a shift in status. Mycelium is moving from niche curiosity to a circular option for both materials and food. The question worth watching is not whether it works, but which sector it reshapes first: fashion, packaging, or food.
Key takeaways
- Mycelium grows from agricultural waste and composts back into the soil.
- It can replace plastics, animal leather, and resource-heavy food ingredients.
- MycoWorks opened the first commercial-scale fine-mycelium plant in 2023.
- Ecovative makes both packaging and leather alternatives from the same organism.
- Durability, cost, and consistent scale-up are still the open challenges.
Frequently asked questions
What is mycelium used for? It is grown into compostable packaging, leather alternatives, and high-protein food ingredients, using agricultural waste as feedstock.
Is mycelium leather as good as animal leather? Companies like MycoWorks say their fine-mycelium material rivals calfskin, though durability and cost at scale are still being proven.
Why is mycelium considered sustainable? It is grown from waste, is biodegradable, and can replace plastics and animal-derived materials with a lower carbon footprint.
