Sustainability & Circularity
Sustainability and circularity in textiles cover recycled fibers, third-party certifications such as GOTS and OEKO-TEX, and circular strategies like recycling, resale, and repair. Together with traceability systems, these tools help the industry reduce waste, verify material and chemical claims, and keep fibers and garments in use longer.

What are recycled fibers and how are they made?
Recycled fibers are produced from material diverted from the waste stream rather than from virgin raw inputs. Sources are typically described as pre-consumer (production scrap and offcuts) or post-consumer (used products such as discarded garments or bottles). The two principal routes are mechanical recycling, which shreds or grinds material back into fiber, and chemical recycling, which breaks material down to monomers or other feedstock that can be re-polymerized or re-spun. Mechanical recycling is generally simpler and lower-input but can shorten fiber length and affect strength, often requiring blending with other fibers. Chemical recycling can yield fiber closer to virgin quality and handle certain blends or contaminated inputs, but is more process-intensive. Both natural fibers (such as cotton) and synthetic fibers (such as polyester) can be recycled, though feedstock purity, sorting, and fiber-type separation are common technical challenges.
Why do GOTS and OEKO-TEX certifications matter?
Third-party certifications give buyers and brands an independent way to verify claims that are otherwise hard to confirm by inspection. GOTS (Global Organic Textile Standard) addresses textiles made from organic fibers, setting environmental and social criteria across processing stages, restricting certain chemical inputs, and requiring chain-of-custody so certified material can be traced through the supply chain. OEKO-TEX refers to a family of independent standards. Several focus on testing finished textiles and components for the presence of regulated and harmful substances, providing assurance on chemical safety; other modules in the family address production-site conditions and chemical management. Because their primary emphases differ, GOTS and OEKO-TEX are frequently used alongside one another rather than as direct substitutes.
What does circularity mean for textiles?
Circularity aims to keep textiles and their constituent fibers in productive use for as long as possible and to recover value at end of life, in contrast to a linear take-make-dispose model. It begins at the design stage with choices that favor durability, repairability, mono-material construction, and ease of disassembly, which make later recovery feasible. During and after a product's first life, circular strategies include repair and maintenance to extend wear, resale and secondhand markets, rental and reuse models, remanufacturing, and finally recycling of fibers back into new material. These approaches are often described as a hierarchy in which reuse and life extension are generally preferred over recycling, and recycling is preferred over disposal.
How does traceability support sustainability claims?
Traceability is the ability to follow a textile product and its inputs through stages of the supply chain-fiber, yarn, fabric, processing, and assembly-and to document where and how each step occurred. It underpins chain-of-custody, which records the custody of certified or claimed materials as they move between operators so that a final claim (for example, recycled or organic content) can be substantiated. Traceability mechanisms range from documentation and transaction certificates to digital identifiers and product-level data records. Robust traceability supports due-diligence efforts, helps detect substitution or mixing of materials, and complements certification: standards set the criteria, while traceability provides the evidence trail showing those criteria were met for a specific batch or product.
GOTS vs OEKO-TEX: qualitative scope and coverage
| Characteristic | GOTS | OEKO-TEX (standard family) |
|---|---|---|
| Primary focus | Organic-fiber textiles with environmental and social processing criteria | Tested chemical safety of textiles and inputs, with additional modules for production and chemical management |
| Fiber requirement | Requires a defined share of certified organic natural fibers | Generally not tied to organic or fiber-origin requirements |
| Scope of criteria | Covers ecological and social/labor criteria across processing stages | Core modules center on substance testing; broader modules address site conditions and chemical inputs |
| Chain-of-custody / traceability | Requires traceability of certified material through the supply chain | Certification applies to tested products/components; some modules address process and supply-side |
| Typical use case | Verifying organic content and responsible processing of natural-fiber textiles | Demonstrating that products have been tested for harmful substances |
| Relationship | Often used together with OEKO-TEX rather than as a substitute | Complements organic and processing standards such as GOTS |
