(Un)sustainability

The clothing and textile industry is huge

Worth over US$ 1 trillion world-wide

It contributes to 7% of world exports

It employs approximately 26 million people

However as an industry the clothing industry is locked into a cycle of unsustainability

The relationship between productivity (added value) and resourceuse has entered into a chronic and unsustainable pattern

Definition of Sustainability

“Corporate Sustainability is a business approach that creates long-

term shareholder value by embracing opportunities and managing

risks deriving from economic, environmental and social

developments.“ (DJSI, business oriented)

“..development meeting the needs of the present without

compromising the capacity of future generations to meet their own

needs.“ (Brundtland, society oriented)

“improved quality of life without compromising the quality of life of

future generations“ (UK government)


2009 MARCH

Definition of Sustainability

This demands an integrated management of three dimensions

Triple Bottom Line


2009 MARCH

Lenzing’s Approach

Sustainability is the cornerstone of Lenzing’s philosophy

We create our products from renewable raw materials

We work towards ecological production and energy generation

Our processes are geared to protecting the environment

We strive to produce ecologically sustainable and commercially

successful products

Products that are safe to use and safe to dispose of

4


2009 MARCH

Transforming philosophy into technology

Use wood from sustainably managed forests

Improve resource efficiency of production processes (raw materials,

chemicals, energy, water)

Avoid or reduce the use of harmful chemicals (chlorine compounds,

APEO’s, …)

Close the loops of industrial processes by appropriate recovery and

recycling technologies (acetic acid, xylose, sodium sulphate,…)

Minimize pollution of air, water & soil by efficient treatment systems

Evaluate the environmental footprint of products and processes as a

basis for continuous improvement

Identity crisis?

“Yes I’ve been using TENCEL………it’s a type of nylon’”

Identity crisis ………less so within the textile trade

Identity crisis ……….far more so with consumers

Unlike certain textile fibres

• Cotton – absorbent, comfortable

• Linen – cool

• Wool – warm

• Polyester – easy care

• Cashmere – soft

MMC fibres do not have a profile within the consumer’s psyche

So how would I sum up man-made cellulosic fibres?

Why cellulose?

Most important natural building block

Available in abundance

Cellulose is generated by photosynthesisconsumes CO2

Biodegradable / compostable

Renewable

Sustainable

Recyclable


2009 MARCH

Man-made cellulosics

Lenzing fibers use cellulose from trees

as their raw material

Wood is a renewable resource

Trees grow on marginal land unsuitable

for food crops

Lenzing only uses raw material from

sustainable sources which are certified

by an independent certifying bodies

FSC

PEFC

SFI

CSA

17


2009 MARCH

Wood as a raw material

Storageof the forest’s carbon right through the life of the products and beyond, through recycling

Substitutionfor other products which produce higher CO2 emissions

Recoveryof the energy stored in the wood at the end of the products’ life by combustion as a substitute for fossil fuels

Renewalof the forests, as timber use stimulates the expansion of forests, increasing the carbon sink effect and sequestering more CO2 from the atmosphere

Questions

What is the impact of fibres on global problems such as …

• Global warming

• Depletion of limited resources

• Impact on human health

• Impairment of ecosystems

Is the environmental impact of fibres relevant on a global scale ?

Do natural fibers show a better eco footprint than man-made fibres ?

Can we measure the environmental footprint of Lenzing’s fibres in

direct comparison to cotton and synthetic fibres ?

The best tool used to answer these questions is a Life Cycle Analysis (LCA) acc. to ISO 14040 ff

LCA of fibres

Fibres are raw materials for textile and nonwoven products

There are huge differences in usage patterns and lifetime

Fibre blends are very common

A comparative cradle-to-grave assessment of different fibre

materials on the basis of the same final product is difficult and often

not realistic (PP shirt?)

To compare the LCA aspects of different fibre materials it is useful,

to take a “cradle-to-factory-gate” approach and then include “final-

post-consumer-disposal”

Land Usage (Utrecht LCA)

Cotton US : 0,88 ha/t

Cotton China : 0,77 ha/t

Cotton average US &China : 0,82 ha/t

Cotton World average : 1,06 ha/t

Lenzing Modal : 0,58 ha/t

TENCEL® (Austria) : 0,21 ha/t

Cotton needs about 4-5 times more land per tonne of fibre than

eucalyptus-based TENCEL®

Further to this trees are grown on what is known as marginal land

whereas cotton is grown on agricultural land

Water consumption (Utrecht LCA)

Pulp and fiber production are known to be water intensive

The water consumption in cotton is frequently under-rated

There is no artificial irrigation for trees

Pulp and fibre production requires water for processing and cooling

The comparative water consumption figures for our fibers are :

Lenzing Modal : 494 m³/t, TENCEL® (Austria) : 266 m³/t

This represents about 10 - 20 times less water than cotton

Previously cotton data was taken from a publication which reported

up to 29,000 m³/t consumed for cotton in Sudan

This is roughly 100 times more than for TENCEL®

The recent lower figures for cotton irrigation result from improved

irrigation practices, higher yields (GMO) and the allocation of ~15%

of the water consumption to the by-product cotton seed

Summary of LCA

Oil based fibres require more non-renewable energy and generate more greenhouse gases than the other fibres

Cotton and PLA both need arable land for their production

PLA cannot be readily compared with the other fibres because of the absence of published information on the CML indicators

Cotton stands out because of the very significant land and wateruse and a significantly higher impact in terms of both aquatic and terrestrial toxicity

Overall, Lenzing Fibers have an extremely favourable eco profile

Global Relevance

Global cotton production* accounts for:

16% of the global impact on freshwater aquatic ecotoxicity

11% of the global impact on terrestrial ecotoxicity

2.6% of the global water use**

Global polyester fiber production*** accounts for :

0.12% of the global greenhouse gas emission

0.31% of the global abiotic depletion

*) Based on the global impact and production figures from 1995 and calculated from present consumptionand emission rates of US and Chinese cotton production assuming that this is representative for theglobal cotton production in 1995**) Source : A. Chapagain, A. Hoekstra, et al. 2006***) calculated from present consumption and emission rates of WE producers and 1995 global production

Conclusions

Lenzing man-made cellulosic fibers offer a sustainable solution for the needs of the Textile Industry

With pressure on oil reserves, water supplies and arable land, cellulose based man made fibres offer an excellent option to help conserve the planet’s resources

Alternative staple fibers are dependent on polymers from oil, orrequire arable land and significant water use for their feedstock

Extensive experience and best practice in manufacturing mean that Lenzing can offer a sustainable option


2009 MARCH

Conclusions - beyond organic?

Ultimately Lenzing cellulosic fibres offer a convincing eco-footprint:

• No pesticides

• No herbicides

• No irrigation

• Use of low grade land

• No GMO

• Natural, renewable and recyclable raw material
