    • Sustainable Textiles?
    • What we are discussing g today?• Sustainability and sus stainable manufacturing• Why suddenly sustain Why suddenly sustain nability is under lime  nability is under lime light? g• Sustainability rating sy ystem• Sustainability in textile chain• Measuring sustainability in textile chain• N l i l ti / B i h New legislation / Buying‐houses requirement i t• Q/A
    • Sustainable developm ment: It is the developme t th t meets the needs i th d l ent that t th d of the present without compromising the ability of future gen nerations to meet their own needs.
    • Renewable resource 6 of 42 A substance of economic valu th t A bt f i lue that can be replaced or  b l d replenished in the same amo ount. Some renewable resources h have essentially an endless  supply, such as solar energy, wind energy and geothermal  l h l i d d h l pressure, while other resourcces are considered renewable  even though some time or ef h h f ffort must go into their  ff h renewal, such as wood, oxyge en, leather and fish. Most precious metals are con nsidered renewable as well;  even though they are not nat turally replaced, they can be  recycled because they are no ot destroyed during their  extraction and use.Dr. S. P. Abbas Oct. 2012
    • Resource – rate of use 7 of 42 Fifty years ago, the world was  Fift th l Consumption Discovery consuming 4 billion barrrels of  oil per year and the aver rage  discovery was around 30 discovery was around 30 billion 0 billion. 0 Today we consume 30 billion  Today we consume 30 billion barrels per year and the  discovery rate is approacching 4  billion barrels of crude p billion barrels of crude per year. per year.  pDr. S. P. Abbas Oct. 2012 Asi ia newspaper, 4 May 2005, quoted by Rob Hopkins, The Transition Handbook, p. 21

    • Solutions 31 of 42 I. The solutions are complex, and made more so by I The solutions are complex, and made more so by  the lack of a definitive “sus stainable” textile. II. It is not as straightforward as “natural fibres are  better than synthetic better than synthetic”. III. When using natural fibres, the energy, water, and  chemical use in cultivation, , production and  consumer use, washing and care needs to be  consumer use, washing and care needs to be considered, as do issues su uch as environmental  damage, and workers expo damage and workers expo osure to hazardous  osure to hazardous chemicals, dust and fumes.Dr. S. P. Abbas Oct. 2012
