Beyond Fast Fashion: A Comparative Review of Upcycling and Recycling Strategies in Sustainable Fashion Design

The environmental impact of the global fashion industry has intensified concerns regarding unsustainable production practices and the rapid accumulation of textile waste. As the fast fashion model continues to dominate global clothing markets, researchers and industry stakeholders are increasingly exploring circular strategies capable of reducing environmental harm while maintaining economic viability. Among the most widely discussed approaches are recycling and upcycling, both of which aim to extend the lifecycle of textile materials and reduce dependence on virgin resources. However, existing academic literature often discusses these strategies separately, with relatively few studies offering a systematic comparison between them within the context of sustainable fashion design. This study presents a structured literature review that critically examines recycling and upcycling as complementary strategies within circular fashion systems. Academic articles, books, institutional reports, and conference publications published between 2010 and 2024 were identified through systematic searches of databases including Scopus, Google Scholar, and JSTOR. After applying inclusion criteria related to relevance, academic credibility, and thematic focus, 65 sources were selected and analyzed using thematic content analysis. The findings indicate that recycling is primarily associated with industrial-scale material recovery and technological processing that allows large volumes of textile waste to be converted into new fibers. While this approach can reduce reliance on virgin materials, it may involve technological limitations such as fiber degradation and energy-intensive processing. Upcycling, in contrast, is strongly linked to design innovation and creative reuse, enabling designers to transform existing garments or textile waste into new products without destroying the original material structure. Upcycling can promote emotional durability, cultural value, and consumer engagement in sustainable fashion, although it often faces challenges related to scalability and integration within industrial supply chains. The study argues that recycling and upcycling should not be viewed as competing strategies but rather as complementary components of a broader circular fashion ecosystem. Hybrid models that combine recycling infrastructure with design-led upcycling practices may offer more holistic solutions to the environmental challenges facing the fashion industry. By synthesizing existing research and presenting a comparative framework, this paper contributes to sustainable fashion scholarship and provides insights for designers, policymakers, educators, and industry stakeholders seeking to transition toward regenerative fashion systems.
