Mushrooms

Biological systems are adaptable, live, breathe and regenerate themselves
Building materials such as insulation foam are harmful to the environment and do not rot for hundreds of years Mushrooms can be used for this very function
The mushroom bricks are made from the roots of common tree fungi from the forest, such as the tinder fungus or the shiny lacquer fungus.
Organic waste from the agricultural and wood industries such as straw, hemp fibers, corn stalks and sawdust are also required. They act as a substrate, are mixed with the mycelia and a nutrient solution and filled into special containers such as hollow bricks.
Fungi, whose filamentous network can spread underground over immense areas, are a kind of waste disposal in nature, masters of the decomposition of biomass, but also masters of synthesis. They could break down plant-based raw materials into their components using active enzymes, but also reassemble them for a wide variety of products.
The fungal mycelium can be used to produce three-dimensional composite materials, bio-bricks. They can be used to make furniture, produce insulating materials and create buildings. The big plus here is that the building materials made from mushrooms are compostable.
Mushroom bricks, known as bio-bricks, which are made from mushroom threads and plant residues, can be used to construct houses and buildings that are as stable as concrete.
