Yes, dyehouses can cut water and energy through low liquor ratio machines, heat recovery, water reuse, high-fixation dyes and processes with fewer rinses. Waterless technologies exist for polyester, but they are not widespread. There is no dyeing without impact, so avoid vague claims.
Ask concrete questions: the liquor ratio, how the wastewater is treated, which dyes are used and whether valid certificates exist for the dyeing unit. Do not assume certifications; ask for the document and check it. A fabric that is dyed right first time, without re-dyeing, is also a water saving.
