Factors such as using renewable resources utilization of waste materials as raw materials, high biodegradability of wastes have major importance to ensure sustainability. Using agricultural wastes, which are renewable natural fibers on an annual basis, as raw materials in composite production also means that waste materials are kept in the material cycle. When considered as a raw material, mushroom is also a renewable resource and it takes part in material production since mycelium acts as an adhesive with its enzymes between natural fibers. Due to being completely organic, composite materials made of mushroom and natural fibers can be fully degraded in nature at the end of their product life cycle. In this study, a composite material has been developed by using wheat straw as the substrate and mycelium of Pleurotus ostreatus as the binder while the production method is an organic growth process. In flammability tests, it was measured that the ignition started at the 67th second. After immersion in water for 24 hours, it is determined that the water absorption value of the material is 257% and thickness expansion is between 2.55-3.63%.
