“…Throughout history, the durability, toughness, and flexibility found in processed animal-based leather have led to its high demand worldwide.

The growing demand for a sustainable leather industry with a low environmental impact has prompted the development of alternative vegetable-based materials. In this study, a biodegradable mushroom-based leather derived from the fruiting body of Phellinus ellipsoideus is investigated. The biodegradable leather proves to be thermally stable up to 250 °C. The mechanically robust macrostructure combines a tensile strength of 1.2 MPa and ductility (101% strain at break) attributed to the natural balance of chitin (0.3) and proteins (0.7) constituting the mycelium fibers. The chitin–protein system results in an intrinsic scratch-resistant structure with exciting damping properties in a low frequency range. Enhanced damping capabilities within 5–20 Hz (tan δ: 0.1–0.20) are attributed to the macrostuctural alignment of the mycelium under cyclic tension. Whereas, increasing frequencies >20 Hz induce micromolecular interactions between chitin and proteins within the fibers. Exposure of the bioleather to acidic (pH 4, 5) and basic (pH 8, 9) media demonstrated the selective dissolution of proteins (basic) and chitin (acid) components within the mycelium, opening an opportunity for tunable mechanical response. Reducing the protein content induced an increase in stiffness and strength (pH 8 and 9), while reducing its chitin component showed variable ductility (pH 4 and 5). Owing to the entirely natural composition of the mushroom leather, intrinsic antifungal and antibacterial properties found in the mycelium resist fungal invasion and bacterial growth. Thus, this study displays the unique morphology–property relationship of a biodegradable mushroom leather, proving its potential as a fully sustainable and environmentally friendly alternative.

Various solutions that have been proposed to address the contamination problem of leather tanning wastewater at El Cerrito (Valle del Cauca, Colombia), have generated conflicts between stakeholders. Therefore, with the purpose of selecting a sustainable alternative for the reduction of chromium present in liquid effluents of the local tanning sector, the Social Multi-Criteria Evaluation (SMCE) method was used to analyze three proposed treatment options. These consisted of a physicochemical treatment based on MgO precipitation and acid re-dissolution, a biotechnological treatment with native yeasts coupled to Cleaner Production (CP) and a non-treatment option. During the evaluation, the social, economic, environmental and technical criteria considered, allowed for the selection of the biotechnology alternative, as the treatment option with the highest sustainability. The physicochemical alternative demonstrated a low acceptance while the non-treatment option proved unfeasible, by affecting the natural environment and social component and was favored only by the economic criterion

RESUMEN Se estima que el 85% de los insumos químicos usados por las industrias de curtiembres europeas para producir 1000 kg de cuero crudo se vierten a los afluentes de recurso hídrico en forma de contaminantes, entre ellos el Cromo VI (Cr (VI)) ABSTRACT In order to produce 1000 kg of leather, it is estimated of 85% of chemical input, used by European tanning plants, is discharged as contaminant. Among of them, Cr (VI), this is a toxic compound of easy adsorption. In that sense, the present work is focused on the removal of Cr (VI) in synthetic solution prepared from Cr (VI) estimated concentration found in wastewater sample discharged by tanning industries (Cr (VI): 32,6 mg/kg). Thus, five filters packed with orange (Citrus sinensis) and plantain (Musa AAB) peels were used in laboratory scale PALABRAS CLAVE:Biofiltro, Cromo VI, Cáscaras de plátano (Musa AAB) y naranja (Citrus sinensis), Metales pesados.
