Lenzing Modal® Edelweiss

 Lenzing presents an environmental innovation – Lenzing Modal® Edelweiss – a new 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* * http://www.apparelcoalition.org/

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. 1,2 Forest land use Agricultural land use 1,0

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!

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

Lenzing Modal® more then fibers…

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!!

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
