Impact of lots of people
7 Billion people in 2011 / 9 billion people by 2050 Our dependency on many current production methods comes at a huge and unsustainable

Benefit to brand
house/retailer
Feature Benefit to processor
Claim lower water use Single bath system Decrease water consumption
Potential for lower carbon footprint Low processing temperature Decrease energy consumption &
CO2 emissions
1.Create flexible fading effects on
one substrate
2. Reduce the number of substrates
required to get varied wash effects
Color modification of indigo &
sulphur dyestuff
Differentiated and varied casts
compared to the chemical
treatment
Improve quality and consistency
Controlled shade adjustment Lower material rejection compared
with chemical bleach
Controllable and reproducible
process
Reduce the variation batch on
batch
Increase care for people Neutral pH and biodegradable Gentle & safe processing
conditions
No damage to LYCRA® elastane
fiber containing denim when
compared to chemical bleaching
processes
No strength loss Reduce the risk of fabric damage
