Recycled old clothing is becoming a source of high-end regenerated raw materials for the luxury industry. Data from the China National Textile and Apparel Council (CNTAC) shows that China generates over 26 million tonnes of waste textiles each year, yet the regeneration utilisation rate is less than 15%. About 70% of old clothes enter industrial regeneration processes, and after more than a dozen purification steps, fibres meeting standards can reach the raw material requirements for luxury production. One tonne of qualified waste polyester clothing can yield 0.9 tonnes of high-purity regenerated polyester fibre, with performance equal to or even better than virgin fibre, at a cost more than 30% higher than virgin fibre.

Key Points

  • China generates over 26 million tonnes of waste textiles annually, with a regeneration utilisation rate below 15%; raising it to 30% could save nearly 8 million tonnes of crude oil and cut carbon emissions by nearly 20 million tonnes per year (CNTAC data)
  • About 70% of old clothes enter industrial regeneration processes; less than 30% — only items 90% new or better and undamaged — enter donation or affordable resale channels after disinfection
  • The regenerated raw material side doesn't care about how new the clothing is, only about fabric purity: solid-coloured garments of 100% pure cotton or 100% polyester are optimal; one tonne of waste polyester can be refined into 0.9 tonnes of high-purity regenerated polyester fibre

Many people's impression of old clothing recycling stops at "second-hand resale" or "charitable donation," but the actual channel diversion goes far beyond that. According to industry processes, only less than 30% of old clothes — those 90% new or better, undamaged and stain-free — enter charitable donation or affordable resale after strict disinfection, while the remaining roughly 70% flow into industrial regeneration.

There are two common misconceptions on the consumer side. First, that the newer the old clothes, the more valuable they are — the regenerated raw material side does not price on this basis. Whether garments are new or old, pilled or seam-split, does not affect the fibre quality after purification; what truly determines value is fabric purity and contamination. Solid-coloured garments of pure cotton or pure polyester are most welcomed by the regeneration supply chain; blends, due to complex composition and high separation costs, struggle to meet the raw material standards of high-end brands; large-area screen prints, rivets, sequins and other decorations are likewise rejected by high-end regeneration chains due to excessive impurities. As long as there is no contamination from strong acids, alkalis or other chemical reagents, and no stubborn mildew or oil stains, all can be processed after disinfection and impurity removal.

Second, that old clothes can ultimately only be made into mops and workwear. Regenerated polyester fibre is not inferior to virgin fibre in performance, and is superior in some metrics. Although it costs over 30% more, precisely because of this, it has secured a place in the regenerated raw material procurement of luxury goods and high-end apparel, with demand rising year by year.

For ordinary households, improving recycling efficiency can start with two things. First, do basic sorting: pick out garments that are mouldy, contaminated with chemical reagents or heavily oil-stained for separate handling, and roughly classify the rest by fabric type. Second, avoid casual disposal: synthetic fibres take over a hundred years to naturally degrade, and incineration releases harmful gases, so handing them to formal recycling channels is the better choice.

From an industry perspective, old clothing recycling has upgraded from low-value disposal to a decarbonisation link that drives the textile raw material supply chain. Every one percentage point increase in the regeneration utilisation rate means a simultaneous decline in crude oil consumption and carbon emissions, and will also push more high-end brands to include regenerated fibres in their regular procurement lists.
