Building on ZDHC’s Foundations for the Next Phase of Impact
As the textile and apparel industry evolves, circularity is increasingly shaping how materials and processes are approached.
At ZDHC, our work on sustainable chemical management has contributed to some of the underlying conditions required for circular systems. A key focus has been on how materials move through production, ensuring that inputs are appropriate, processes are controlled, and outputs do not create unintended downstream risks.
The ZDHC MRSL is central to this approach. By restricting hazardous substances at source, it helps reduce the presence of chemicals that may limit the ability of materials, whether virgin or recycled, to be reused, repurposed, or further processed.
In parallel, ZDHC has developed guidelines for fibres such as Recycled Polyester and Dissolving Grade Pulp, providing clarity on how these materials can be produced in alignment with safer chemistry principles, where the chemical profile of materials influences their suitability for reuse or recycling.
Together, these efforts have contributed to greater consistency in how materials are produced and managed. This consistency is an important precondition for enabling circular flows.
As work on circularity progresses, it is becoming evident that material innovation and recycling technologies alone are not sufficient.
The ability to reuse materials at scale depends on a number of additional factors, particularly the availability of reliable information, the consistency of inputs and the conditions under which materials are processed.
Building on its existing work, ZDHC is expanding its scope to address several of these areas:
These areas extend the focus from managing chemical risk towards enabling conditions that support more circular use of resources.
For circularity to be implemented at scale, these elements need to be integrated into existing frameworks in a consistent way.
As part of this next phase, ZDHC is working to build on and align the guidelines and frameworks within the Roadmap to Zero (RtZ) Programme, with the objective of embedding circularity considerations more explicitly.
This includes strengthening linkages between existing tools and expanding them where needed, so that they can support not only compliance and performance, but also circular outcomes.
The emphasis remains on practical implementation, ensuring that any extensions are aligned with how the industry operates and can be applied consistently across the value chain.
Circularity introduces new requirements, but it also builds on existing foundations.
The safe and consistent management of chemistry remains a key enabler, particularly as materials move across multiple lifecycles. Without this, efforts to reuse or recycle materials may introduce variability or unintended risks.
By extending its current approach, ZDHC aims to support the development of systems where materials, chemicals, and resources can be managed in a way that is both controlled and adaptable to circular use.
This will require continued collaboration across the value chain, as well as a focus on aligning technical approaches with practical implementation.
