Additionally, since mycelium materials return to the soil after their useful life, they pose no pollution threats, presenting a circular model of production and disposal.

Process of Creating Mycelium-Based Bricks

Preparing the Mycelium Culture

The first step in creating mycelium bricks involves preparing the mycelium culture. A mushroom spore is introduced into a growth medium that often contains organic waste. The spore germinates into mycelium, growing and expanding within the medium.

Forming the Mycelium Mixture

Once the mycelium has colonized and integrated the material, it is physically manipulated into the desired shapes. This enables the formation of customized mycelium blocks or bricks for construction purposes.

Growing and Drying the Mycelium Bricks

After shaping, the mycelium mixture is placed in a controlled environment to grow further. The resulting mycelium bricks are then dried to prevent further growth and to strengthen their structural properties.
