Lenzing Modal® Edelweiss
Lenzing presents an environmental innovation – Lenzing Modal® Edelweiss – anew fiber produced by an innovative, eco-friendly manufacturing technology.
Agenda
Lenzing responsibility in the environment (LCA, Apparel coalition)
Why Lenzing Modal® with edelweiss technology?
Lenzing Modal® more then fibers – by product – full integration
Edelweiss technology
Premium eco product development
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 offossil energy (even less than cotton) due to pulp and energy integration on site.
7
Lenzing responsibility in the environment
Global Warming Potential / Greenhouse Gas Emissions :
Lenzing Modal® and Lenzing Viscose® Austria are the only man-made fibers which arecarbon neutral.
8
Lenzing responsibility in the environmentLand Use :
All wood-based man-made cellulose fibres need less land per ton of fiber than cottoncultivation.
The productivity of Lenzing Modal® from beech wood is 50% higher than that of cotton.

Lenzing responsibility in the environmentWater Use :
Consumption of water for cotton is about 10 to 20 times higher than for all Lenzingcellulose fibres.
While water for irrigation of cotton fields is extracted from surface and ground water andcompletely “consumed”, 80-90% of the water used for industrial production of Lenzing’sTencel®, Lenzing Modal® and Lenzing Viscose® fibres is cooling water, which isimmediately 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 afibre by calculating its relative contribution to the global environmental impact in therespective category.
Ozone layer depletion and photochemical oxidation are of negligible importance forall of the fibres.
The impact of cotton on fresh water and terrestrial toxicity is orders of magnitudehigher 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 edelweisstechnology
Average production increase has become the environmental challenge forLenzing
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!

Beech wood the source of LenzingModal®
15
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 higherthan from a cotton field
16
Only Lenzing Modal® is made of beechwood
Beech wood is the DNA of Lenzing Modal®
Sustainable through natural growth
Multiplies via “rejuvenation” without having tobe planted and irrigated by man
No chemicals used for growing
No genetic manipulation
17
Lenzing Modal®
CO2-neutral fiber thanks to technology from Lenzing
The Lenzing pulp factory does not require anyadditional energy and in fact supplies energy to theentire Lenzing site
Thus Lenzing is a pioneer in the field of wood-organic refineries
These carbon-neutral thermal processingtechniques were developed by Lenzing engineersand are unique to Lenzing

Lenzing Modal® more then fibers…
Lenzing Modal® + Edelweiss
21
The edelweiss technology marks the absolute peak of environmentallyresponsible manufacturing processes by using only oxygen chemistry starting fromthe pulp production up to the final fiber - and still achieves the reliable LenzingModal® with its well established properties
With the development of edelweiss technology Lenzing again has set the globalenvironmental standard for producing Modal fibers

Edelweiss Technology
Production with Oxygen chemistry
starting from the pulp production
and now also for the fiber production itself!!

Well known attributes stay
Lenzing Modal® produced by edelweiss technology retains well establishedproperties from Lenzing Modal®
Lenzing Modal® produced by edelweiss technology results in a product withslightly lower - but natural - whiteness
Lenzing Modal® Edelweiss performs identically to the conventional LenzingModal® 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 ecofibers will enable the design of true eco collections and help our customers toprotect the environment across the board

Summary
Lenzing Modal® consumes less fossil energy than synthetic fibers andcotton.
Lenzing Modal® is carbon neutral; the fiber does not contribute to globalwarming.
Lenzing Modal® has a 50% higher yield per ha of land than cotton.
The Lenzing Modal® production process consumes 10 times less waterthan cotton irrigation; 90% of the Modal water consumption is just forcooling.
Lenzing Modal® does not have a significant contribution to ozone layerdepletion, human toxicity, pollution of soil, smog formation oreutrophication.
The aggregated score of the total environmental impact of LenzingModal® is only 3% that of cotton.
