NIKE encourages each vendor to have a short-term strategy based on improving manufacturing        process        efficiencies        –        fixing         leaks; replacing old dyeing machines with more        water-efficient        equipment;        optimizing         rinsing and scouring steps; and ensuring their wastewater        meets        the        requirements        of        the         ZDHC Wastewater Guideline – since all of these will        result        in        a        more        cost-effective        long-term         strategy for wastewater recycling.
