Pleurotus ostreatus Mycelium and Sugarcane Bagasse as Substitute Environment-Friendly Material for Polystyrene Foam

Biodiversity in ecosystems is threatened by plastic waste, a significant pollution problem. The research aims to use plastic, Pleorotus ostreatus mycelium, and sugarcane bagasse develop an eco-friendly biomaterial. preparation consisted of three phases: (1) Treatment the underlying layer, (2) inoculation fungus (three different concentrations: 15%, M1; 20%, M2; 25%, M3), (3) dehydration physical characterization results (density, water absorption, texture) showed that average density varies between 127.86 131.19 kg/m3; also, M1 sample had high percentage absorption (23.55%), while M2 obtained lower percentages (11.79%). In bending test, samples M3 higher structural resistance with stress values 0.682 0.68 MPa, respectively. Based on results, produced biomaterials may serve as alternative expanded polystyrene (EPS). Due their moldable characteristics, they can be used non-structural construction, packaging, various architectural applications. provided promising results; however, additional parameters must evaluated able commercialize them.
