Used clothing recycling is not the source of the "black-heart cotton" that outsiders fear, but a resource-based recycling industry covering three stages: collection, processing, and sales. After professional sorting, discarded clothing can be processed into primary products such as cloth strips, mop cloths, and greenhouse insulation felt, or refined through regeneration technology into raw materials like cotton, nonwoven fabric, and chemical fiber. Accessories such as metal zippers and plastic buttons are separated separately and enter the metal and plastic recycling streams.

Key Points

  • For every ton of used clothing recycled, professional processing can yield 0.99 tons of nonwoven fabric or 0.99 tons of color-sorted cotton yarn.
  • This output is equivalent to saving 1.1 tons of textile raw materials or 0.8 tons of cotton.
  • Industry sales channels include renewable resource companies, textile manufacturers, and export operators, all of which are lawful and compliant business entities.

The industry's profit mainly comes from the primary processing of used clothing and the reuse of raw materials. Sorting is the core step: after clothing is classified by material, color, and condition, it goes down different processing paths. Some becomes primary products such as cloth strips, mop cloths, and greenhouse insulation felt, while the rest enters the regeneration stage and is converted into high-value raw materials such as cotton, nonwoven fabric, and chemical fiber. Non-textile components such as zippers and buttons are not discarded either, but recycled separately as metal and plastic.

The resource math is quite straightforward. According to industry estimates, one ton of used clothing can be processed into 0.99 tons of nonwoven fabric, or 0.99 tons of color-sorted cotton yarn; the corresponding resource substitution is 1.1 tons of textile raw materials or 0.8 tons of cotton. This means the value of used clothing recycling lies not only in "disposing of waste" but also in reducing the consumption of virgin raw materials.

In terms of volume, the total amount of discarded clothing generated by each city every year reaches tens of thousands of tons. If these clothes can be effectively utilized, the effects of saving resources and protecting the environment will appear at the same time. In the context of "Internet Plus," building online clothing recycling platforms is seen as a feasible path to broaden the channels for recycling waste textiles, making it more convenient for used clothes scattered in households to enter the formal recycling chain.

For the industry, the degree of standardization of this chain determines whether it can shed the "black-heart cotton" label. Only when sorting, processing, and reuse each play their proper role can used clothing truly turn from waste into priced raw materials.
