Strong Fibers

Strong Fibers

Spent mushroom substrate from shiitake mushrooms (Lentinula edodes) was converted into usable fibers using an extrusion process. The resulting sheets were up to 7.5× stronger than commercial birch pulp sheets, thanks to residual mycelial fibrils that improved fiber bonding without chemical treatment.
