 Summary
Lenzing responsibility in the environment
LCA Study of fibers
 An LCA study on fibers was conducted by
Dr. Martin Patel and Li Shen from
Utrecht University in cooperation with
Lenzing.
 The study was subject to a Critical
Review by LCA experts in USA, UK and Germany.
Lenzing AG is a part of sustainable Apparel collation*

Lenzing responsibility in the environment
Consumption of non-renewable energy :
Lenzing Modal® & Lenzing Viscose® Austria have the lowest consumption of
fossil energy (even less than cotton) due to pulp and energy integration on site.
6
Lenzing responsibility in the environment
Global Warming Potential / Greenhouse Gas Emissions :
Lenzing Modal® and Lenzing Viscose® Austria are the only man-made fibers which are
carbon neutral.
7
Lenzing responsibility in the environment
Land Use :
All wood-based man-made cellulose fibres need less land per ton of fiber than cotton
cultivation.
The productivity of Lenzing Modal® from beech wood is 50% higher than that of cotton.

Lenzing responsibility in the environment
Water Use :
Consumption of water for cotton is about 10 to 20 times higher than for all Lenzing
cellulose fibres.
While water for irrigation of cotton fields is extracted from surface and ground water and
completely “consumed”, 80-90% of the water used for industrial production of Lenzing’s
Tencel®, Lenzing Modal® and Lenzing Viscose® fibres is cooling water, which is
immediately returned to surface waters without contamination.

Lenzing responsibility in the environment
Relative Environmental Impact :
The graph presents an aggregated score of the total environmental footprint of a
fibre by calculating its relative contribution to the global environmental impact in the
respective category.
Ozone layer depletion and photochemical oxidation are of negligible importance for
all of the fibres.
The impact of cotton on fresh water and terrestrial toxicity is orders of magnitude
higher than for all man-made fibres and represents a problem of global relevance.
The fibres with the lowest environmental impact are Tencel®, Lenzing Modal®
and Lenzing Viscose® Austria.

Why Lenzing Modal® with edelweiss
technology
 Average production increase has become the environmental challenge for
Lenzing
 Target is to keep up with environmental protection installations
 To stay the best-practice-fiber producer in the world
 Lenzing Modal® 2011 – capacity increase!!!!
 Leads to a new development in production. EDELWEISS!

Tbc…….
Beech wood the source of Lenzing
Modal®
Beech
 Lenzing Modal® is extracted from beech wood
 Beech is the mother of the forest
 History of the beech: for the Celts in the Iron Age –
beech trees were mythical trees
 Beech is grown in Northern and Central Europe
 Yield of beechwood cellulose is two times higher
than from a cotton field
15
Only Lenzing Modal® is made of beech
wood
 Beech wood is the DNA of Lenzing Modal®
 Sustainable through natural growth
 Multiplies via “rejuvenation” without having to
be planted and irrigated by man
 No chemicals used for growing
 No genetic manipulation
16
Lenzing Modal® = CO2 NEUTRAL
CO2-neutral fiber thanks to technology from Lenzing
 The Lenzing pulp factory does not require any
additional energy and in fact supplies energy to the
entire Lenzing site
 Thus Lenzing is a pioneer in the field of woodorganic refineries
 These carbon-neutral thermal processing
techniques were developed by Lenzing engineers
and are unique to Lenzing
17
= CO2 NEUTRAL
Full integration

Lenzing Modal® + Edelweiss
Edelweiss Technology
 The edelweiss technology marks the absolute peak of environmentally
responsible manufacturing processes by using only oxygen chemistry starting from
the pulp production up to the final fiber - and still achieves the reliable Lenzing
Modal® with its well established properties
 With the development of edelweiss technology Lenzing again has set the global
environmental standard for producing Modal fibers
21
Edelweiss Technology
 Production with Oxygen chemistry
 starting from the pulp production
 and now also for the fiber production itself!!
Botanic Purity
22
Well known attributes stay
 Lenzing Modal® produced by edelweiss technology retains well established
properties from Lenzing Modal®
 Lenzing Modal® produced by edelweiss technology results in a product with
slightly lower - but natural - whiteness
 Lenzing Modal® Edelweiss performs identically to the conventional Lenzing
Modal® fiber. The fiber properties, softness and color brilliance, remain intact.
Even the processing in the textile supply chain is the same.
 Blending Lenzing Modal® produced by edelweiss technology with other eco
fibers will enable the design of true eco collections and help our customers to
protect the environment across the board

depletion, human toxicity, pollution of soil, smog formation or
eutrophication.
 The aggregated score of the total environmental impact of Lenzing
Modal® is only 3% that of cotton.
 Lenzing Modal® produced by edelweiss technology is bleached by
oxygen chemistry.
28
Eco textiles
 Samples with edelweiss technology are produced
 The whole product development range is based on sustainable/ecological
production. We developed woven as well as knitted fabrics with GOTS certified
dyestuffs and auxiliaries
 Customers can sample Edelweiss quantities to produce special Eco products –
