| '''Look for design opportunities to avoid bleaching. Darker, duller shades may not require bleaching prior to dyeing/finishing.''' ||
Lighter, brighter shades do need to be chlorine bleached before dyeing.
|-
| '''Promote suppliers who use ozone bleaching processes. <br/><br/>Promote the aesthetic of ozone bleach effects.''' || • Ozone has limited availability, and is relatively expensive since it requires investment in an ozone generator.<br/> • Ozone produces a different aesthetic than chlorine derivative or permanganate bleaching.
|-
| '''Promote suppliers who use enzyme process bleaches.<br/><br/>Promote the aesthetic of enzyme bleach effects.''' || Enzyme produces a different aesthetic than chlorine derivative or permanganate bleaching.
|-
| '''Promote suppliers who use low-temperature peroxide bleach processes, such as pad-batch systems.'''
|| Pad-batch bleaching is much slower than high-temperature peroxide bleaching, and requires significant floor space to store batches for long periods of time.
|-
| '''Avoid chlorine bleaching if possible.<br/><br/>For fabric bleaching prior to dyeing/finishing, do not accept chlorine-derivative bleaches when peroxide will suffice.''' || Peroxide might be slightly more expensive than chlorine-derivative bleaches, but they are less toxic.
|-
| '''Promote proper wastewater treatment.'''
