Abstract
The increasing environmental issue related to textile waste, especially synthetic fibers treated with acrylic resins, demands the creation of sustainable recycling techniques. Biotechnological methods, such as microbial degradation, present a viable solution for the elimination of these coatings and the recovery of important fibers. This study investigates the potential of a biotechnological approach for the removal of acrylic resins from coated woven textile wastes. The biodegradation process of coated woven fabric after the pretreatment at a high temperature (121 °C) or 6% H(2)O(2) was performed using the hydrocarbon-degrading bacterial strain Gordonia alkanivorans S7. Over a 72 h biodegradation period, an increase in emulsifying and esterase activities was observed. A reduction mass of the coated textile waste by up to 7 wt% was achieved, and the elimination of acrylic resin was confirmed through FTIR analysis. The findings indicate the usefulness of the biotechnological method in eliminating acrylic resin from textile waste, presenting a viable strategy for polyester fiber recovery and substantially mitigating its environmental impact.
