Less than 1% of the material used to produce clothing is recycled into new garments. This low recycling rate occurs even as 10% to 40% of all garments manufactured remain unsold, according to Sciencedirect. This imbalance reveals a critical textile waste problem within the fashion industry.

The fashion industry urgently needs to transition to a circular economy to combat massive waste, but the core concepts of circular fashion are poorly defined and its economic benefits may be significantly overestimated. Designers and companies seeking circular fashion longevity waste reduction strategies face considerable challenges.

Based on the current lack of rigorous definition and overblown economic projections, the widespread adoption of truly effective circular fashion practices will likely be slower and more challenging than currently anticipated. This could lead to continued environmental impact if the approach is not critically re-evaluated.

The fashion industry is projected to consume up to 25% of the world's carbon budget by 2050, according to pmc.ncbi.nlm.nih.gov. The projection that the fashion industry will consume up to 25% of the world's carbon budget by 2050 mandates new models to manage resources and waste. The concept of a circular economy proposes a systemic shift from the traditional linear model of 'take-make-dispose'.

This transition aims to keep products and materials in use for as long as possible, extracting maximum value from them while in use, then recovering and regenerating products and materials at the end of their service life. Such an approach seeks to reduce waste and pollution, circulate products and materials, and regenerate natural systems. For fashion, this means rethinking design, production, and consumption to extend garment lifespan and minimize environmental harm.

The current 'circular fashion' paradigm, however, faces significant scrutiny regarding its foundational claims. Circular fashion aims to keep resources in use for as long as possible, but its proposed framework has encountered definitional and economic challenges. Many of its core concepts stem from 'gray literature', which includes reports and policy documents not typically subjected to rigorous academic peer review, according to Frontiersin.
