Public Disclosure Portal

The ZDHC Roadmap to Zero Programme has developed the Public Disclosure Portal. This portal provides the industry with an overview of the supply chain performance with respect to the conformance to the ZDHC Wastewater Guidelines.

What kind of wastewater test data is disclosed?
  • Anonymised, aggregated, colour coded wastewater testing data per facility pertaining to ZDHC Wastewater Guidelines Table 2A-N (MRSL Parameters):
  • Verified data are wastewater testing data that are directly uploaded by the ZDHC Accepted Laboratories under the ZDHC wastewater and sludge testing programme upon the completion of wastewater testing. The ZDHC Accepted Laboratories have been reviewed by ZDHC technical staff to ensure they have the technical ability in the appropriate testing analytes, as well as reviewing the laboratories quality assurance programme.
  • Unverified data are wastewater data that are provided by third parties. These wastewater testing may be conducted by any laboratories, which ZDHC has not necessarily reviewed their testing capability and their quality assurance programme.
