Developing mycocomposites (mycelium composites, biocomposites) using mycelium and domestic biomass, such as Reed and Kudzu, can reduce greenhouse gases. Oak chip sawdust is generally used in the production of this Mycocomposite, but domestic biomass development is considered essential because it requires alternatives due to recent regulations. Since this Mycocomposite has properties that vary depending on the strain and the biomass used, Trametes orientalis mutant strain through gamma-ray was used to observe several characteristics in domestic biomass. The measured strain characteristics included mycelium growth rate, thickness using an optical microscope, compressive strength using a Universal testing machine, and water absorption rate. Oak chip sawdust, Reeds, and Kudzu were used for biomass. The results of the measurement and the growth rate of each mycelium were similar. However, the Oak chip sawdust and Kudzu mixture composite are the best results when measured with compressive strength and water absorption. Therefore, Kudzu, domestic biomass, show the potential for the alternative plastic component.

Various eco-friendly materials are being developed to meet global environmental demand. Among them, multi-purpose alternatives such as eco-friendly packaging, building materials, leather, and large sports using mushroom mycelium are under research and development, and mycelium composite materials, a combination of biomass and mycelium, can be physically and chemically treated to control physical properties. In this study, we investigated the use of Trametes orientalis mycelium as a substitute for wood panels and extended polystyrene (EPS) in packaging and insulation. The compressive strength of mushroom materials was higher than EPS (Korean Standard Bead Act No. 3), which is widely used in daily life. In addition, low heat dissipation showed high safety when exposed to fire, and the density of mushroom materials was similar to that of EPS. Mushroom materials are biodegradable materials and are expected to replace materials such as EPS by reducing weight and improving function
