Materials derived from petroleum are used for the most diverse applications, however the process of deterioration or decomposition of most of these materials is slow which results in a major environmental problem A promising alternative to replace petroleum derivatives are biomaterials produced from fungal mycelia grown on plant residues (biocomposites) that are completely biodegradable and have the potential to generate materials with diverse mechanical properties. This project aims to evaluate the mechanical properties of mycocomposites produced with sugarcane bagasse residues and the cultivation of fungi of the species Trametes villosa and Ganoderma lucidum. Specifically, density, compressive strength, water absorption and thermogravimetric analysis are analyzed. In addition, we analyzed the influence of adding mining tailings to culture media. The results obtained for density ranged from 74.5 kg/m³ to 220.62 kg/m³. The thermogravimetric analysis showed an initial degradation temperature of ± 250 ° C, in relation to water absorption the analysis showed a non-linear behavior of the water absorption curve, explained by the hydrophobic nature of the mycelium and the hydrophilic nature of the fibers.
