13. Stahl
EasyBlue Tan™

14. EasyBlue Tan™
One of the many great things about Stahl EasyBlue Tan™ is that you
don‘t have to choose between quality and sustainability as it offers
both.
To be more precise about the environmental benefits:
■ Water reduction of up to 40%
■ Less energy required
■ 80% less salt in waste water
■ Chemicals: 45% less chrome, 60% less acid and 20% less nitrogen
The result? Premium leather quality with the following properties:
■ Very tight, compact and flat grain
■ Higher resistance to milling, less nubuckation
■ Higher tear strength
■ Super white leather achievable
■ High light fastness and heat resistance
■ Less visible veins
■ Fuller flanks

21. We value
partnerships
“The future is green and
sustainable, it really is the
only way to go.”
Marja Baas, Myomy

22. We value
partnerships
“As a fashion designer, I believe
leather should be produced with
respect for people, animals and
the environment.”

23. Social
36.000.000 kilo’s of salt can be
yearly saved in the automotive
industry, by changing the way
we tan leather. Less waste,
less damage to the environment.

24. Social
We could save 7.500.000 KWH
per year in the automotive
industry, enough to power
2500 households for a year.

25. Social
We could save 300.000.000 liters
of water per year in the automotive
industry, by changing the way we
tan leather.

26. We believe that if it can be
imagined, it can be created
