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.

12

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

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.

Lenzing Modal® produced by edelweiss technology is bleached byoxygen chemistry.
