An important element of the value chain
Fibres are an important part of the value chain. Therefore it’s a logical next step for ZDHC Roadmap to Zero Programme to include fibre production processes and their raw materials. In 2018, the scope of the Programme extended to include the production of Man-Made Cellulosic Fibres (MMCF). This is the first fibre production area included in the Programme. More materials will be added in the future.
Global viscose production is growing fast, which is why the initial focus is on Man-Made Cellulosic Fibres (MMCF; including viscose, modal and lyocell). MMCFs are produced from natural feedstock like wood or plants, using hazardous chemicals. Within the production process of viscose and modal, particularly where that’s not an integrated (closed loop) process, chemicals react with the cellulose. This creates by-products, which can be released into the air, water and soil, so we’ve been working to tackle the issue.
An 2018 industry expert report commissioned by ZDHC concluded that restricting chemicals via the ZDHC MRSL approach would not work. The restrictions would halt most MMCF production processes. We would achieve most impact by collaboratively setting guidance around good chemical management and limits for wastewater, sludge, and air emissions during fibre production. At the same time ZDHC can continue researching MMCF production processes using less hazardous chemicals.
In March 2018, ZDHC hosted the first multi-stakeholder MMCF roundtable with representatives from approximately 80% of the global MMCF production. Several ZDHC Signatory Brands attended, including C&A, Coop Switzerland, Esprit, Inditex, H&M, M&S, Primark, PVH Corp and F&F, as well as Value Chain Affiliates Lenzing Group, BIRLA CELLULOSE, Sateri, Canopy, Textile Exchange, Bluesign and the China Chemical Fibers Association (CCFA), the Collaboration for Sustainable Development of Viscose (CV) and the Partnership for Sustainable Textiles.
The roundtable agreed that ZDHC should lead a collaboration to develop a framework of guidelines for wastewater, sludge, waste and air emissions specific to MMCF production, and expectations for process by-product recovery rates. The guidelines will, for now, focus on MMCF production. Dissolving pulp production processes will be considered at a later stage.
Ensuring consistent, accurate testing data
ZDHC acceptance means that a laboratory has the personnel, equipment and processes in place to analyse wastewater and sludge samples. It does NOT however offer any assurance that data will be acceptable for any given sample. That can only be assured by examination of the associated quality control samples.

A paradigm shift is happening throughout the value chain. By managing chemical inputs, we
want to ensure safer products, cleaner water and fresher air. That will truly benefit both people and planet. Our solutions help the industry to transform their value chains.
As part of the open approach we take, our door is always open for new information. The ZDHC Submission platform is part of this two-way communication. It's a channel to gather new submission to amend a limit, propose a new substance or a process that should be added to the ZDHC MRSL or the ZDHC Wastewater Guidelines. If we are missing information, we want to know about it. This platform will allow people to submit their suggestions quickly and easily.
The ZDHC MRSL is regularly updated with new chemicals and processes that should be phased out of the supply chain. We want to ensure those updates are always done in a transparent, consistent way. So we created this guidelines document to keep everything on track. It explains the process of how we update the ZDHC MRSL.

Collaboration is a key success factor when implementing the ZDHC MRSL. We’ve identified four key stakeholder types that play a key role: Certification Bodies, “Chemical” Formulators, Facilities/Suppliers and Brands/Retailers. By implementing in a collaborative, connected way, these stakeholders can reduce the impact of the implementation efforts. This document provides a standard approach to help achieve this.
The ZDHC InCheck Report (Inventory Check) helps a supplier to check their chemical inventory against the ZDHC MRSL Accepted Certifications in the ZDHC Gateway. This helps the Supplier to improve their chemical management practices. The InCheck Guidelines contain all necessary information for the industry regarding the Performance InCheck Report.
Commodity chemicals are within the scope of the ZDHC MRSL, but are excluded from the Performance Incheck Report. This is due to the challenge of engaging the commodity chemicals industry in the ZDHC Gateway and populating these products in the ZDHC Gateway database of ZDHC MRSL conformant products.
Commodity chemicals tend to be low priced, and easily replaced with another similar product without any need for specific process change. They are not expected to remain on the finished article, but to be washed off in processing, putting the risk on wastewater and sludge quality. Being sold in pure form it is unlikely that they are a ZDHC MRSL intentional addition.
This document outlines the requirements for indicating ZDHC MRSL conformance. It shows how confident we are that a chemical formulation would always conform. That's useful information for chemical formulators wanting to make safer products. Because ZDHC Accepted Certification Standards are used to indicate conformance, this document also shows those standards how to earn ZDHC acceptance.

Onsite assessment of chemical hazard assessment capability plus evidence that Level 1 and Level 2 requirements are fulfilled.
This online platform helps us to scale our efforts. We created the world's first database of safer chemistry for the entire value chain. This digital tool simplifies the search for alternatives. It provides an easy entryway to register and browse safer chemistry solutions. The Gateway builds trust and reduces the administrative burden throughout the value chain.
The ZDHC Gateway - Chemical Module is a web-based solution that supports the entire value chain. This advanced search engine enables registering and finding chemical formulations that comply with the ZDHC MRSL. It simplifies the search for more sustainable chemicals and best practices.
Chemical formulators that join the ZDHC Gateway play a leading role in advancing the industry towards safer chemical management. When their product conforms to the ZDHC MRSL, they can upload it and show its performance. This platform lets formulators classify their chemical products, while virtual catalogues help them reach out to customers.
ZDHC ChemCheck Report
Formulators can generate a ZDHC ChemCheck Report for their published products on the ZDHC Gateway - Chemical Module. They can use it to assure customers that their chemical products meet ZDHC MRSL requirements. This report can be downloaded, printed or shared electronically via PDF. More info.
Suppliers can browse through a central library of chemical formulations that conform to the ZDHC MRSL. For various chemical products, ZDHC MRSL Conformance Levels and details are available. Suppliers can invite their chemical formulators to register more products on the ZDHC Gateway, which also supports continuous improvement of the ZDHC Gateway chemical inventory.
ZDHC InCheck
This report shows how much a chemical inventory conforms to the requirements of the ZDHC MRSL. A comprehensive overview of a supplier’s chemical inventory and its overall conformance is produced, all in an easy-to-read report. ZDHC InCheck provides clear, understandable results and helpful guidance to increase the use of safer chemistry. More info.
By acting as a library for safer, innovative chemical alternatives, the Gateway increases transparency, while supporting more sustainable procurement decisions. Brands can use the platform to educate their suppliers on the more sustainable procurement options. It also helps in asking suppliers to raise the bar on chemical management.
Increased Efficiencies
The Gateway removes the burden of maintaining positive lists and highlighting preferred chemistry to multiple suppliers. Brands can simply mark their preferences in one place, where suppliers can then find them. In addition, brands can see verified wastewater results via ClearStream Reports. These are based on tests conducted by ZDHC Accepted Laboratories, in accordance with the ZDHC Wastewater Guidelines.
