AI Technical Summary
Existing paper materials lack sufficient bending resistance and water resistance, necessitating an innovative approach to enhance these properties.
Integrating mushroom mycelium with paper by contacting it for several days, allowing the mycelium to spread and strengthen the paper, particularly through the decomposition of irregularly shaped parts.
The integration of mushroom mycelium increases the paper's bending resistance and water resistance, effectively utilizing food and agricultural waste while maintaining structural integrity.

Abstract
Description
Technical Field
[0001] The present invention relates to paper strengthened with mycelium.
Summary of the Invention
Problems to be Solved by the Invention
[0002] Create paper strengthened with the mycelium of fungi. Means for Solving the Problems
[0003] Contact the paper with mushroom fungi and wait for about several days. Effects of the Invention
[0004] The paper thickens with the mycelium and especially seems to increase in bending resistance and water resistance. Modes for Carrying Out the Invention
[0005] Contact the paper with mushroom fungi and wait for about several days. The mushroom mycelium spreads on the paper.
[0006] For cultivated edible mushrooms, there doesn't seem to be much difference in their behavior towards paper.
[0007] Mixing a small amount of mushroom spawn with sawdust and burying the paper is considered the simplest method.
[0008] Spent mushroom beds can also be used. Since the C / N ratio is low, it is considered better to mix them little by little with others.
[0009] The mushroom fungi clearly divide into a part that makes it dense and a part that makes it void. For roll paper etc., it can be applied as it is and the layers seem to be maintained (even when it looks thinly dense).
[0010] The conditions for generating mushrooms (spores) such as high moisture content and generation temperature are deliberately avoided.
[0011] Mushroom mycelium appears to prioritize the decomposition of irregularly shaped parts during its dormant phase, forming a cohesive structure. In the case of paper, decomposition (disappearance) begins from the corners. In cases of nutrient deficiency, the spread of mycelium may not change, but the corners and edges of the paper may start to chip or break.
[0012] Sterilization should be carried out as appropriate. Fast-reproducing, color-causing bacteria do not spread to paper immediately, but rather contaminate it. TIFF2026104748000001.tif17108
[0013] Mushroom mycelium has the property of breaking down easily decomposable substrates and making difficult-to-decompose parts rigid, allowing it to lie dormant. It can also incorporate a wide range of organic matter. By making the paper portion less strong and using food and agricultural waste, and reinforcing it with mycelium, it is thought that resources can be used effectively.
[0014] The characteristics of fungi and mycelium are diverse, so it seems worthwhile to experiment with many different types.
