Abstract:
Industrial wastes and by-products are sources of functional biopolymers with interesting properties for textile applications. In the present study, wastes produced by different industries, namely beer spent grain (BSG), hot trub (HT), vine shoot trimmings (VST), tobacco plant stream (TPS) and chestnut hedgehog (CH) were explored for added value oils extraction. This research evaluated the influence of granulometry, solids loading and the combination of different enzymes (cellulase, pectinase, xylanase) in both oil yields and functional characteristics extraction. The higher oil yields were obtained from CH and TPS at 20% and 10% solids loading, in the presence of xylanase and pectinase respectively, corresponding to an increase in 62% (CH) and 140% (TPS) compared to the control (no enzymes added). Oils rich in phenolic compounds, within a range of 22.05 ± 0.161-2670.44 4 ± 80 mg GAE/g waste biomass and high antioxidant activity above 60% (except for BSG) were obtained. Textiles functionalized with oils extracted from VST revealed potential for water repellence properties. Textiles with a UPF of 30 were developed by functionalization with CH oils. The outcomes from the presented work demonstrate a sustainable oil extraction methodology and further application to the development of functional textiles.
