ZDHC Certification

The Zero Discharge of Hazardous Chemicals (ZDHC) certification is a program aimed at reducing the environmental impact of the textile, leather, and footwear industries by eliminating the use of hazardous chemicals. It was initiated by a group of major brands and retailers in the industry to promote sustainable chemical management practices.

The ZDHC program provides tools, standards, and guidance to help companies manage their chemical usage more responsibly. It includes a Manufacturing Restricted Substances List (MRSL) that specifies which chemicals are prohibited or restricted in the production of textiles, leather, and footwear. Companies that meet the requirements of the ZDHC program can achieve ZDHC certification, demonstrating their commitment to sustainable chemical management.

The ZDHC program includes several levels of certification, each representing a different stage of commitment to sustainable chemical management. These levels are:

Level 0: Commitment to the ZDHC program principles and objectives.

Level 1: Implementation of the ZDHC MRSL and conformance to the Wastewater Guidelines.

Level 2: Implementation of Level 1 requirements, plus conformance to the Chemical Management System (CMS) framework.

Level 3: Implementation of Levels 1 and 2 requirements, plus the achievement of third-party certification of the CMS.

Level 4: Implementation of Levels 1, 2, and 3 requirements, plus demonstration of continuous improvement in chemical management performance.

Each level builds upon the previous one, with Level 4 representing the highest level of commitment and achievement in sustainable chemical management. Companies can choose the level that best fits their goals and capabilities.

The ZDHC Manufacturing Restricted Substances List (ZDHC MRSL) is a list of chemical substances banned from intentional use in the processing of textile materials, leather, rubber, foam, adhesives and trims used in textiles, apparel, and footwear industry. Intentional use means the substance used deliberately in a chemical product to achieve a desired look or functionality.

The ZDHC MRSL goes beyond the traditional approaches to chemical restrictions, which only apply to finished products ( Restricted Substances List - RSL) and is focused on consumer safety. The MRSL approach also helps protect workers, local communities, and the environment from the possible impacts of harmful chemicals.

Chemical formulations covered by restrictions in the ZDHC MRSL include, but are not limited to, cleaners, adhesives, paints, inks, detergents, dyes, colourants, auxiliaries, coatings and finishing agents used during raw material production, wet processing, process machinery maintenance, wastewater treatment, sanitation, and pest control. ZDHC MRSL limits apply to substances in commercially available formulations, not those from earlier stages of chemical synthesis.

Using chemical formulations that conform to the ZDHC MRSL allows suppliers to assure themselves, and their customers, that banned chemical substances are not intentionally used during production and manufacturing processes.

By adhering to the ZDHC MRSL, companies can ensure that their products are manufactured using safer chemicals and contribute to the goal of zero discharge of hazardous chemicals into the environment.

The Zero Discharge of Hazardous Chemicals (ZDHC) Wastewater Guidelines provide guidance to textile, leather, and footwear manufacturers on managing and treating wastewater to prevent the discharge of hazardous chemicals into the environment. The guidelines aim to protect water resources, aquatic ecosystems, and human health by reducing the environmental impact of wastewater from manufacturing processes.

Key aspects of the ZDHC Wastewater Guidelines include:

1. Chemical Limits: The guidelines specify the maximum allowable concentrations of certain hazardous chemicals in wastewater, including substances listed in the ZDHC MRSL and other chemicals of concern.

2. Sampling and Testing: The guidelines provide recommendations for sampling and testing wastewater to ensure compliance with chemical limits. This includes guidance on sampling locations, frequency, and analytical methods.

3. Wastewater Treatment: The guidelines recommend various wastewater treatment technologies and practices to remove or reduce hazardous chemicals before discharge. This may include physical, chemical, and biological treatment methods.

4. Monitoring and Reporting: The guidelines outline monitoring and reporting requirements to track the performance of wastewater treatment systems and ensure compliance with chemical limits.

5. Continuous Improvement: The guidelines encourage companies to continuously improve their wastewater management practices by implementing best available technologies and practices.

By following the ZDHC Wastewater Guidelines, manufacturers can reduce their environmental impact and contribute to the goal of zero discharge of hazardous chemicals into the environment.

The Zero Discharge of Hazardous Chemicals (ZDHC) certification offers several benefits to companies in the textile, leather, and footwear industries, including:

1. Improved Environmental Performance: ZDHC certification helps companies reduce their environmental impact by eliminating the use of hazardous chemicals in their manufacturing processes, thereby reducing water and soil pollution.

2. Enhanced Brand Reputation: Companies that achieve ZDHC certification demonstrate their commitment to sustainable chemical management, which can enhance their brand reputation and appeal to environmentally conscious consumers.

3. Access to Markets: Some brands and retailers require their suppliers to be ZDHC-certified, which can provide certified companies with access to new markets and business opportunities.

4. Cost Savings: By adopting more sustainable chemical management practices, companies can reduce the costs associated with chemical procurement, waste management, and regulatory compliance.

5. Risk Mitigation: ZDHC certification helps companies mitigate the risks associated with the use of hazardous chemicals, such as regulatory fines, legal liabilities, and reputational damage.

6. Continuous Improvement: The ZDHC program encourages continuous improvement in chemical management practices, helping companies stay ahead of regulatory requirements and industry best practices.

Overall, ZDHC certification can help companies in the textile, leather, and footwear industries operate more sustainably, reduce their environmental impact, and enhance their competitiveness in the market.

To obtain a Zero Discharge of Hazardous Chemicals (ZDHC) certificate, companies in the textile, leather, and footwear industries must follow these general steps:

1. Commit to ZDHC Principles: Companies must commit to the ZDHC program's principles and objectives, including the goal of zero discharge of hazardous chemicals.

2. Implement ZDHC MRSL: Implement the ZDHC Manufacturing Restricted Substances List (MRSL) to ensure that no prohibited or restricted chemicals are used in the manufacturing processes.

3. Conform to Wastewater Guidelines: Ensure that wastewater from manufacturing processes meets the ZDHC Wastewater Guidelines, which specify the maximum allowable concentrations of certain chemicals in wastewater.

4. Implement Chemical Management System (CMS): Implement a Chemical Management System (CMS) that conforms to the ZDHC CMS framework. The CMS should include procedures for chemical inventory management, risk assessment, training, and communication.

5. Third-Party Certification: Depending on the desired level of certification, companies may need to undergo third-party certification of their CMS to demonstrate compliance with ZDHC requirements.

6. Continuous Improvement: Continuously improve chemical management practices and performance to achieve higher levels of certification and maintain compliance with ZDHC standards.

7. Application and Evaluation: Companies can apply for ZDHC certification through the ZDHC Gateway – Chemical Module. Applications are evaluated based on the company's implementation of ZDHC standards and the results of third-party audits, if applicable.

8. Certification: Upon successful evaluation, companies will receive a ZDHC certificate indicating their level of certification and commitment to sustainable chemical management.

It's important to note that the specific requirements and processes for obtaining ZDHC certification may vary depending on the certification body and the level of certification sought. Companies should refer to the latest ZDHC guidelines and requirements for detailed information.
