Circular business models in the apparel industry signify a transformative shift from the traditional linear “take-make-dispose” approach to a more sustainable framework that emphasizes resource efficiency and waste reduction. These models aim to extend the life cycle of clothing through strategies such as resale, rental, repair, and upcycling, addressing the environmental challenges posed by the fashion industry while catering to evolving consumer preferences for sustainable options. With projections indicating that circular practices could capture 23 per cent of the global fashion market by 2030 and generate significant economic value, the implementation of these models requires a comprehensive approach that integrates innovation, policy, and consumer behaviour. This chapter serves as an overview of the book, which explores various dimensions of circularity in textiles and apparel, including the significance of consumer education and the potential for innovative recycling methods to minimize waste and enhance economic viability.
