| These are parameters that are amenable to treatment by an effluent treatment plant, meaning proper operation is critical to controlling their discharge. The parameters mostly relate to the proper operation of an effluent treatment plant (including not overloading its capacity). They include factors such as temperature, pH, biological oxygen demand, or chemical oxygen demand (Appendix A, Tables 1A-1B). ZDHC Signatory Brands acknowledge the relevance of these parameters and their high importance for the textile, apparel and footwear industry. Therefore, these guidelines align on these parameters with foundational, progressive and aspirational limit values. |
