Water and Energy Reduction in Clothing Production
Dyeing gets most of the attention in conversations about textile production and water, but it’s only one stage in a much longer process. Spinning, weaving, finishing, and general facility operations all draw on water and energy too, and small brands rarely have visibility into any of it unless they specifically ask.
This guide covers where water and energy actually get used across production, what genuine reduction looks like at the facility level, and what questions are worth asking a manufacturer directly. It builds on our broader guide to sustainable production, and pairs closely with our guide on low-impact dyes, since dyeing is one part of this broader picture.
Where Water and Energy Get Used in Production
Fabric production draws water at multiple stages beyond dyeing: washing raw fiber, various wet processing and finishing treatments, and general facility cooling and cleaning. Energy use covers running spinning and weaving machinery, heating water and finishing chemicals, and powering the facility itself.
Reduction opportunities exist at nearly every one of these stages, though the scale of impact varies. Facility-wide changes, like switching energy source or installing water recycling systems, tend to move the needle more than smaller process tweaks, but both matter.
Renewable Energy in Manufacturing
Some manufacturers now run partially or fully on renewable energy, most commonly solar, either generated on-site or purchased through renewable energy certificates that fund clean energy elsewhere on the grid. This is one of the more verifiable claims in this category, since a facility either has documented renewable capacity or it doesn’t.
Ask directly what percentage of a facility’s energy comes from renewable sources and how that’s verified. A vague claim of being “eco-friendly” is worth much less than a specific, documented figure you can actually reference in your own product story.
Water Recycling and Closed-Loop Systems
Closed-loop water systems treat and reuse water within the facility rather than discharging it after a single use and drawing fresh water for the next batch. This significantly reduces both total water consumption and the volume of wastewater requiring treatment or discharge.
The Zero Discharge of Hazardous Chemicals (ZDHC) program is a widely recognised industry initiative specifically focused on eliminating hazardous chemical discharge from textile production, and manufacturer participation in it is a useful signal worth asking about directly.
Questions to Ask Your Manufacturer
- What percentage of facility energy comes from renewable sources, and how is this documented?
- Does the facility operate a water recycling or closed-loop system, and for which production stages?
- Is the facility part of ZDHC or a similar recognised industry sustainability initiative?
- How is wastewater treated before discharge, and is that treatment independently verified?
Few small brands will get a fully detailed answer to every question, but a manufacturer’s willingness and ability to answer specifically, rather than vaguely, tells you a lot about how seriously they treat this area.
What You Can Control as a Brand
Beyond manufacturer selection, you have direct control over order efficiency. Consolidating orders to reduce the number of separate production runs, and choosing manufacturers geographically closer to reduce transport-related energy use, both fall within a brand’s own decision-making rather than depending entirely on a factory’s practices.
Production location specifically ties into local and nearshore production, which covers how shortening your supply chain reduces the transport emissions layered on top of manufacturing impact itself.
Common Mistakes
- Only asking about dyeing. Water and energy use spans the entire production process, not just the colouring stage.
- Accepting vague “eco-friendly” claims. Ask for specific, documented figures on renewable energy and water recycling.
- Overlooking your own order patterns. Order efficiency and manufacturer location are decisions within your own control, not just the factory’s.
- Assuming one certification covers everything. Renewable energy, water recycling, and chemical management are separate practices worth verifying individually.
Frequently Asked Questions About Water and Energy Reduction
Fiber washing, wet processing and finishing treatments, and general facility operations like cooling and cleaning all draw on water. Energy powers spinning and weaving machinery, heats water and finishing chemicals, and runs the facility itself.
A closed-loop system treats and reuses water within the facility rather than discharging it after a single use and drawing fresh water for the next batch. This reduces both total water consumption and the volume of wastewater requiring treatment or discharge.
Zero Discharge of Hazardous Chemicals (ZDHC) is a widely recognised industry initiative focused on eliminating hazardous chemical discharge from textile production. Manufacturer participation is a useful signal worth asking about when evaluating a supplier’s environmental practices.
Ask what specific percentage of the facility’s energy comes from renewable sources and how that figure is documented or certified. A vague claim of being ‘eco-friendly’ carries far less weight than a specific, verifiable figure.
Order efficiency and production location are within a brand’s own control. Consolidating orders to reduce separate production runs, and choosing manufacturers geographically closer to your customer base, both reduce impact independent of a specific factory’s practices.
