Bioeconomy in Textile Industry: Industrial Wastes Valorisation Toward Textile Functionalization
Short Introductive summary
In the present study, wastes produced by dif ferent industries with a relevant impact on the Portuguese economy (beer spent grain, hot trub, vine shoot trimmings, tobacco plant stream and chestnut hedgehogs) were explored for added value oils extraction. The enzymatic pre-treatment resulted in higher oil extraction yields for all the wastes tested, except for hot trub (no oil was extracted f rom all the conditions tested) compared to the control treatment. The most notorious increase was about 500% and corresponded to vine shoot trimmings with the addiction of cellulase and pectinase. Considering all the conditions tested, the best oil yield was achieved in the extraction with beer spent grain 0,25mm with the enzymatic combination of cellulase and xylanase (0.097 g oil/g waste biomass/mL extract). The characterization of the extracted oils indicated the presence of phenolic compounds (within a range of 22,05±0,161- 1967,73±16,86 mg GAE/g waste biomass, corresponding the higher value to the oil f rom chestnut hedgehogs. In the DPPH assay, all of the essential oils (except for beer spent grain oil) showed high antioxidant potential, with a radical-scavenging activity above 3329.78 %
