Mycelium Packaging Material is one of the nature’s most powerful gifts, where packaging is grown instead of manufactured.
Made from fungal roots and agricultural waste, it offers a sustainable alternative to petroleum-based plastics, especially Styrofoam, which is difficult to recycle and can persist in the environment for centuries, harming wildlife and human health.
In contrast to Styrofoam, mycelium packaging material is biodegradable, lightweight, durable, safe and highly customisable.
It requires minimal water, energy and chemicals to produce, resulting in a lower carbon footprint.
Unlike some biodegradable plastics such as PLA that need industrial composting conditions, mycelium packaging upon disposal can biodegrade naturally at any environmental condition, enriching the soil and supporting a circular economy.
What is mycelium packaging material?
Mycelium packaging material is a sustainable alternative to traditional non-biodegradable packaging material, which can utilize the root structure of fungi to create an environmentally friendly packaging material.
Mycelium is the thread-like vegetative part of a fungus that plays a fundamental role in the growth and development of mushroom fungi.
Their primary role is to absorb and distribute nutrition for the fungi.
This natural material is known for its ability to form a dense network of fibers, which is creating a strong, durable and versatile structure.
Mycelium produces enzymes that break down organic matter and secretes a natural adhesive or “biological glue” to bind organic waste materials together for forming a cohesive and strong matrix.
What is the difference between mycelium and mushroom?
| Mycelium | Mushroom |
| Mycelium is the thread-like vegetative part of a fungus, consisting of a network of filamentous structures known as hyphae. | Mushroom is the reproductive structure, emerging from the mycelium under specific environmental conditions. |
| Mycelium is typically found underground or within soil. | Mushroom often visible above the ground. |
| Absorption and distribution of nutrients for fungus is their primary role. | Mushrooms produce and disperse spores, which can germinate and form new mycelium. |
| Mycelium is the precursor to mushroom and can persist for much longer periods. | Mushroom is relatively short-lived structures. |
Which mushroom species are most widely used?
Currently, scientists have identified a lot of different types of fungi, but still there are so many types to be discovered.
This means there is a lot of exciting potential for finding new mushroom species in the future.
1. Pleurotus ostreatus (Oyster Mushroom)
Oyster mushrooms are commonly utilized in mycelium packaging material due to their fast growth and ability to degrade a variety of substrates.
2. Ganoderma lucidum (Reishi Mushroom)

4. Phanerochaete chrysosporium
This white rot fungus is well-known for its ability to degrade lignin, a key component in various waste materials. Its robust mycelium makes it suitable for mycelium packaging material.
5. Schizophyllum commune (Split Gill Mushroom)
Split gill mushrooms are notable for their adaptability towards different substrates and rapid growth, making them a practical choice for mycelium packaging material.
Choosing the right species is tough job to make biomaterials efficiently.
When picking species for biomaterial production, researchers consider factors like how dense the mycelium is, how quickly it grows, the cost of the growth media (the stuff it grows on), how harmful it is, how easy it is to grow and the structure of the mycelium.
How to Make Mycelium Packaging Material?
The production process of mycelium packaging material involves several key steps.
1. Substrate Selection
The process begins with the selection of a substrate, which serves as the growth medium for mycelium.
Common substrates include agricultural waste, such as wood chips, hemp hurd, sawdust, corn stover, straw, husks, bagasse or other plant-based materials.
The choice of substrate can impact the final properties and strength of the mycelium-based composite (MBC).
For instance, MBC from sawdust exhibits higher strength as compared to MBC from straw.
2. Sterilization
To create a clean and controlled environment for mycelium growth, substrate should be autoclaved at 121°C for an hour.
This step eliminates the unwanted microorganisms and ensures that the mycelium can grow without any problems.
3. Mixing
After sterilization, the substrate is mixed with mycelium.
After mixing, mycelium begins to grow in network of threads throughout the substrate.
Additional supplements can be added, such as carbon, nitrogen and water for fast and optimum growth.
4. Incubation
The mixed substrate is placed in a controlled environment at specific temperature and humidity level, especially in dark room.
Temperature: 25 – 30 °C
Humidity: 60-65 %RH
(Change in temperature and humidity level may impact the growth rate of fungi)
During incubation, the mycelium rapidly colonizes the substrate and form a dense matrix.
This growth cycle typically takes 5-7 days depending on the specific type of mycelium strain, substrate and environmental conditions.
5. Molding and Shaping
Once the mycelium has sufficiently colonized the substrate, it is ready for molding.
The mycelium-mixed substrate is placed into molds of desired shapes and sizes.
The mycelium matrix can be molded into specific shapes and sizes during the growth cycle.
6. Drying and Heating
After molding, the mycelium-based material is carefully dried in an oven at 100°C for 30-45 minutes to stop further growth of mycelium or to solidify the matrix.
Developments are ongoing for drying and heating in different ways, such as rubbing with herbal oil and cold/hot pressing.
7. Post-Processing (Optional)
Depending on the intended use and application, additional post-processing steps may be carried out, such as water-resistant coating.
Keep in mind that strength of mycelium-based composite (MBC) is highly dependent on fungal strain, substrate type, growth condition, incubation time, additional supplement, fabrication method or post processing.
