Abstract

The rapid expansion of the textile and fashion industries has led to a significant increase in global textile waste, posing serious environmental concerns. As one of the largest global contributors to waste, the textile sector urgently needs innovative, sustainable recycling solutions. This review paper critically examines recent advancements in textile recycling, including mechanical, chemical, and biochemical methods, and compares their efficiency and economic feasibility. It also highlights the role of emerging technologies such as artificial intelligence-assisted sorting, fiber regeneration through circular approaches and supportive global policy frameworks. By addressing key research gaps, this paper provides valuable insights for developing scalable and environmentally friendly textile recycling strategies. It evaluates their sustainability impact and proposes an outlook focused on circular economy, policy integration, and societal transformation. The review emphasizes for the need that integrating AI-based sorting, scalable biochemical recycling, and robust policy frameworks is essential to achieving a circular textile economy.
