Textile Recycling: A Challenge for the Entire Value Chain, Not Just Technology

For many years, textile recycling has often been viewed as a process at the end of a product’s life cycle: clothes that are no longer usable are collected, sorted, and then turned into rags, filling materials, or recycled fibers. This approach still has value, but its limitations are becoming increasingly apparent. If products are designed from the outset with multiple blended fibers, difficult-to-separate accessories, and complex finishing chemicals, recycling plants will struggle to produce consistently high-quality materials, even as processing technology advances.

As a result, the focus of the circular economy in textiles is shifting from the question “can it be recycled?” to “how is the product designed, used, collected, and processed so that it can return to the value chain?” This change is significant for Vietnamese businesses, which are deeply involved in contract manufacturing but still depend considerably on the materials, technical standards, and purchasing requirements of international brands.

Recycling Does Not Begin at the Processing Plant

In essence, a textile product can follow several processing pathways after it is discarded. Products that are still usable can be resold, donated, or reused. Damaged clothing that remains suitable in terms of its materials can be recycled into new textile products. Some items can be mechanically recycled into short fibers, nonwoven materials, or products with lower performance requirements. When these options are not feasible, waste may be incinerated for energy recovery or sent to landfill, depending on the infrastructure and regulations in each market.

These options are not equivalent in environmental or economic value. Reuse generally retains more value than breaking a product down into fibers. Recycling fibers into new products can reduce demand for virgin materials, but its effectiveness depends on the quality of the incoming material stream, the energy used, the chemicals involved, and the plant’s ability to operate consistently. Therefore, a product cannot be considered “circular” solely because it contains a certain proportion of recycled fibers.

Design decisions directly affect the ability to process a product after use. A garment made from only one type of fiber is easier to sort and recycle than a product made from multiple fiber types. Zippers, buttons, labels, sewing threads, waterproof coatings, laminating adhesives, and decorative elements also increase the complexity of disassembly. In practice, products with durable designs that are easy to repair and whose components can be removed may extend their useful life even before they are recycled.

Blended Fibers Are One of the Major Bottlenecks

Blended cotton and polyester fabric is a commonly cited example in discussions about recycling. This combination can provide suitable product characteristics, such as durability, shape retention, or a particular feel when worn. However, separating the components after use is generally more complex than processing a single-fiber material stream. In mechanical recycling, tearing and shredding can reduce fiber length, making recycled fibers less able to fully replace virgin fibers.

Chemical recycling technologies have been developed to process certain materials by separating or converting them into feedstock for new production processes. However, technology is not an automatic solution for every waste stream. Effectiveness also depends on the cleanliness of the materials, their degree of uniformity, the ability to remove dyes and additives, operating costs, energy consumption, and the availability of a collection system of sufficient scale.

Businesses should therefore avoid treating chemical recycling as a reason to delay simpler solutions at the design stage. Reducing the number of materials used, limiting difficult-to-remove components, selecting suitable dyes and finishing processes, and extending product life remain important measures. End-of-life processing technology can only be effective when the material stream is prepared appropriately from the outset.

Collection and Sorting Determine Material Quality

In the textile recycling chain, collection is often more difficult to control than production. Waste generated in a factory can be sorted relatively clearly by composition, color, or production stage. By contrast, post-consumer clothing comes from many households, retail channels, and geographic areas. Products may be dirty, damp, mixed with other waste, or lacking complete information about their fiber composition.

The quality of collected materials directly affects sorting costs and the marketability of recycled products. If workers have to inspect every item, remove accessories, identify its composition, and address contamination, costs can rise quickly. This is why effective collection systems usually require coordination among brands, retailers, logistics providers, sorting facilities, recyclers, and consumers.

Fiber-content labels are an important source of information, but in many cases they are not sufficient for automated sorting or for tracing the full history of the materials. Businesses can supplement this information with data on suppliers, fiber percentages, dyes, coatings, and accessories in product management systems. As requirements for environmental data and traceability increase, material information will become part of competitive capability rather than merely an internal technical record.

Local Infrastructure Must Go Hand in Hand with Brand Commitments

A brand may set a goal of using recycled materials, but that goal will be difficult to achieve without a stable supply. Supply, in turn, depends on the volume of products collected, sorting capacity, and the plant’s input standards. If each brand builds its own small-scale program, the system may become fragmented, increasing logistics costs and leaving processing facilities without enough material to operate efficiently.

Potential solutions include shared collection points, consistent sorting standards, and data-sharing mechanisms among stakeholders in the chain. However, the specific model must suit the conditions of each market. Not every region has a professional recycling network, and not every type of clothing has sufficient value to offset collection costs.

In Vietnam, the challenge also lies in connecting export garment manufacturers, material suppliers, collection facilities, and waste-processing providers. Most contract manufacturers produce according to customer requirements, meaning that decisions about design, materials, and product standards may rest with the brand or buyer. Nevertheless, garment manufacturers can still improve circularity by better controlling production waste, separately sorting each material stream, reducing losses, and maintaining material data.

Policy Pressure Is Expanding from Products to the Entire Chain

In many markets, environmental policy for textiles is no longer focused only on end-of-life waste treatment. Regulators are paying increasing attention to product durability, repairability, material information, restrictions on destroying unsold goods, and producer responsibility after products are sold. These requirements mean that businesses must consider the entire life cycle rather than simply optimizing costs at the sewing stage.

In 2024, the European Union adopted the Ecodesign for Sustainable Products Regulation. This legislation establishes a framework for setting requirements on durability, repairability, resource use, and product information for many categories of goods. Textiles are among the sectors receiving attention as specific product requirements are developed. This approach indicates that exporters will need to monitor not only customs regulations, but also material data and the environmental performance of their products.

Regulation does not mean that every business must immediately switch to a specific recycling technology. More importantly, businesses need to prepare data systems, supplier-control procedures, and evidence supporting material claims. General statements such as “green,” “sustainable,” or “environmentally friendly” will be difficult to substantiate without a clearly defined scope, measurement method, and verification documentation.

Extended producer responsibility requirements may also have different impacts across markets. When collection and processing costs are allocated to manufacturers or brands, businesses have greater incentive to design products that are easier to process. On the other hand, if fee systems do not distinguish between product types, businesses may not receive a strong enough signal to invest in circular design. Fee calculations based on materials, durability, and recyclability could create clearer incentives, but they require appropriate data and management capacity.

Where Should Textile Businesses Begin?

For a garment factory, the first step does not necessarily have to be investing in a recycling line. A step that can be implemented sooner is mapping material flows in production. Defective fabric, fabric ends, leftover fabric, yarn, packaging, and other types of waste should be sorted by composition and condition. When material streams are separated, businesses can more easily identify what can be reused, what can be sold to processing facilities, and what must be handled in accordance with regulations.

The next step is controlling supplier data. Material records should show fiber composition, blend percentages, dyes, finishing treatments, and relevant certifications when required. This data helps businesses answer customer questions more accurately while reducing the risk of making unsupported environmental claims.

At the product level, businesses can work with brands to assess design choices that affect recyclability. Removing a component is not always feasible because the product must also meet functional, aesthetic, and safety requirements. However, the assessment process can help stakeholders identify trade-offs and choose more suitable solutions rather than simply shifting processing costs to the end of the product’s life cycle.

Recycled Materials Should Not Be Equated with a Circular Model

Using recycled polyester or recycled cotton can reduce demand for some virgin materials, but it is not enough to demonstrate that the entire product operates within a circular model. Businesses must also consider the source of the recycled materials, the method used to verify the percentage, product quality, durability, repairability, and the route the product will take after use.

In particular, environmental benefit claims need to be presented within a specific scope. A product containing a percentage of recycled material but wearing out quickly may not deliver the same results as a more durable product that is used for longer. Conversely, a product that cannot yet be fully recycled but has a durable, repairable design and an appropriate take-back network may still make a positive contribution to reducing waste.

Life-cycle assessment is a useful tool for comparing options, but the results depend on the data, assumptions, and scope of the study. Businesses should not use a single indicator to claim that a product is superior in every respect. Cautious communication that clearly states data limitations and distinguishes between targets and achieved results will help build customer trust.

Prospects Depend on the Ability to Coordinate

Textile recycling will struggle to develop if it relies solely on the efforts of processing plants. Designers need to consider product life cycles; suppliers need to provide material data; garment manufacturers need to control waste and processes; brands need to establish take-back mechanisms; consumers need to extend product use and sort items correctly; and regulators need to create suitable standards and infrastructure.

In the short term, the most feasible solutions are often reducing waste at the source, improving product quality, repairing, reusing, and separately sorting valuable material streams. Advanced recycling technologies still require investment, but their commercial effectiveness will depend on scale, a stable supply of materials, and the ability to sell the resulting products.

For Vietnam’s textile and garment industry, the shift toward a circular economy is both a compliance requirement and an opportunity to move up the supply chain. Businesses with strong data management and material-control capabilities, and that can demonstrate performance through reliable documentation, will have an advantage as international customers demand higher environmental standards. Recycling, therefore, should not be viewed as an isolated project at the end of the production line. It is the result of a series of decisions made from the selection of fibers and product design through the organization of production and the moment the product leaves the consumer’s hands.
