Zero Discharge of Hazardous Chemicals (ZDHC) Certification & Testing Programs

Overview

Reducing the discharge of hazardous chemicals in the manufacturing process is vital for the health of communities and the protection of the environment. In today’s transparent global marketplace, any release of harmful toxins in wastewater, accidental or otherwise, is a highly scrutinized issue by regulators and the public at large.

With extensive environmental and safety science expertise in textile, apparel and footwear industries, UL can help retailers and buyers identify potential issues within the supply chain and assist in determining sustainable solutions.

This comprehensive and customizable service includes:

  • Wastewater testing with sophisticated analytical instrumentation and benchmarked limits of detection based on a customer’s unique needs.
  • Wastewater sampling and pre-sampling co-ordination.
  • Posting of test results to public platforms including the preparation, data input and data verification.
  • On-site assessments that cover management systems, chemicals and hazardous substances, water use, quality and monitoring, wastewater treatment and emergency responsiveness, as well as supply chain training and education.
  • Conformance certification to ZDHC MRSL Level 1, which requires a 3rd party review of the documentation or analytical test report, data needs to meet the requirements; Documentation Review (formulation disclosure, MSDS, chemical inventory, test reports); and in the case of lack of data, verification testing will be performed.
