I have a set of chemicals that I would like to submit to ZDHC for review. Are there limits to the kind of submissions that ZDHC will accept?

Everyone agrees that water is a scarce resource and should be conserved. Textile and leather processing being water intensive industries, all efforts should be made to reduce water use in the wet processes. However, it is seen many times that the cost of water is not reciprocative of the investments (in terms of low liqor machines or water saving chemicals) required to reduce its use and hence water efficiency is not always given the importance that it requires. How can we motivate suppliers to invest in water efficiency? Are there any use cases that demonstrate bottomline benefits due to water reduction at a facility? Would linkage of water use to energy reduction help?

Everyone knows wastewater treatment uses a lot of energy, which is a big sustainability challenge. In the textile industry, ZLD (Zero Liquid Discharge) is mostly done using MEE+RO systems, traditional systems are still widely used even though they consume huge amounts of energy. Many suppliers focus only on meeting legal rules (compliance) rather than saving energy, because new technologies need high upfront investment and the benefits take time to recover.

What are the benefits of being a ZDHC Signatory?

We’d like to include the ZDHC logo in some of our communication materials. Could someone clarify which version of the logo we’re allowed to use, and if there are any guidelines we should follow? Thanks in advance!
