What are <strong>the</strong> major effects?<br />

For <strong>the</strong> base case (mak<strong>in</strong>g <strong>the</strong> products as we do<br />

now) <strong>and</strong> each scenario we have calculated a set <strong>of</strong><br />

environmental <strong>and</strong> socioeconomic <strong>in</strong>dicators for <strong>the</strong><br />

T-shirt <strong>and</strong> <strong>the</strong> blouse. <strong>The</strong> results are shown on<br />

<strong>the</strong> two world maps – which to some extent act as<br />

‘graphic equalisers’ – show<strong>in</strong>g how <strong>the</strong> different<br />

measures change with <strong>the</strong> scenarios <strong>and</strong> between<br />

countries. Each measure is scaled consistently on<br />

both figures. Comparison <strong>of</strong> <strong>the</strong>se measures gives<br />

us various key <strong>in</strong>sights <strong>in</strong>to <strong>the</strong> consequences <strong>of</strong><br />

each scenario, <strong>and</strong> from <strong>the</strong> analysis we can make<br />

recommendations for <strong>future</strong> action.<br />

Transport energy drives <strong>the</strong><br />

impact <strong>of</strong> location decisions<br />

For both products, <strong>the</strong> proportion <strong>of</strong> life-cycle energy<br />

used <strong>in</strong> transportation is small, so chang<strong>in</strong>g production<br />

location has only a small global environmental effect.<br />

<strong>The</strong> use <strong>of</strong> novel technology to produce T-shirts<br />

shows additional benefits on a global scale – as<br />

yarn is converted directly to <strong>the</strong> product without <strong>the</strong><br />

<strong>in</strong>termediate stage <strong>of</strong> flat fabric. <strong>The</strong> three measures<br />

<strong>of</strong> environmental impact are all highest <strong>in</strong> <strong>the</strong> UK,<br />

driven by use <strong>of</strong> electricity for wash<strong>in</strong>g <strong>and</strong> dry<strong>in</strong>g,<br />

but <strong>the</strong> figures <strong>in</strong> <strong>the</strong> USA are also high – around half<br />

<strong>of</strong> those <strong>in</strong> <strong>the</strong> UK. <strong>The</strong>se impacts are pr<strong>in</strong>cipally due<br />

to <strong>the</strong> use <strong>of</strong> diesel <strong>in</strong> agricultural mach<strong>in</strong>ery <strong>and</strong> <strong>the</strong><br />

requirement for electricity to power mach<strong>in</strong>es used for<br />

card<strong>in</strong>g, comb<strong>in</strong>g <strong>and</strong> sp<strong>in</strong>n<strong>in</strong>g cotton fibre <strong>in</strong>to yarn.<br />

Energy use <strong>in</strong> produc<strong>in</strong>g fertilisers <strong>and</strong> <strong>in</strong>secticides <strong>in</strong><br />

<strong>the</strong> USA, is relatively unimportant. However, later on<br />

<strong>in</strong> this report, <strong>in</strong> <strong>the</strong> <strong>the</strong>me headed ‘New products <strong>and</strong><br />

materials selection’ we will explore <strong>the</strong> significance<br />

<strong>of</strong> <strong>the</strong>se agricultural chemicals <strong>in</strong> generat<strong>in</strong>g<br />

environmental impacts associated with toxicity.<br />

New bus<strong>in</strong>ess opportunities with flexible technologies<br />

Computerised seamless knitt<strong>in</strong>g mach<strong>in</strong>es comb<strong>in</strong>ed with<br />

CAD (Computer Aided Design technology) <strong>of</strong>fer a significant<br />

opportunity to achieve ‘mass customisation’ <strong>in</strong> <strong>the</strong> <strong>cloth<strong>in</strong>g</strong><br />

<strong>in</strong>dustry, without <strong>in</strong>creas<strong>in</strong>g costs <strong>and</strong> optimis<strong>in</strong>g <strong>the</strong> material<br />

usage thus reduc<strong>in</strong>g waste. <strong>The</strong> comb<strong>in</strong>ation <strong>of</strong> technologies<br />

can enable <strong>the</strong> delivery <strong>of</strong> a whole garment while allow<strong>in</strong>g<br />

<strong>the</strong> product to rema<strong>in</strong> digital until f<strong>in</strong>al manufacture. Digital<br />

communication <strong>of</strong> designs may also allow a <strong>cloth<strong>in</strong>g</strong><br />

manufacturer to distribute production mach<strong>in</strong>es to multiple<br />

locations, such as retail stores, all over <strong>the</strong> country. Production<br />

<strong>and</strong> retail could <strong>the</strong>n take place <strong>in</strong> a jo<strong>in</strong>t facility. This allows<br />

<strong>the</strong> customer to be <strong>in</strong>volved <strong>in</strong> <strong>the</strong> design <strong>of</strong> <strong>the</strong> garment.<br />

3D design technology allows <strong>the</strong> simulation <strong>of</strong> true-to-life<br />

garment <strong>and</strong> fabric drap<strong>in</strong>g us<strong>in</strong>g an ‘Avatar’ – a personalised<br />

body created by scann<strong>in</strong>g techniques that form a virtual 3D<br />

garment over a virtual body us<strong>in</strong>g a 2D pattern <strong>in</strong>put. This<br />

ensures that <strong>the</strong> lead-time <strong>in</strong> gett<strong>in</strong>g <strong>the</strong> prototype right is<br />

reduced <strong>and</strong> gives a customised f<strong>in</strong>al sample which is errorfree<br />

E1 . Novel digital pigment <strong>in</strong>k pr<strong>in</strong>t<strong>in</strong>g technologies can<br />

also be added to enhance this form <strong>of</strong> product <strong>in</strong>novation E2 .<br />

Technically feasible but not pr<strong>of</strong>itable: <strong>the</strong> recam carpet recycl<strong>in</strong>g story<br />

In <strong>the</strong> last half <strong>of</strong> <strong>the</strong> 1990s <strong>the</strong> EC Brite Euram recovery project<br />

RECAM (Recycl<strong>in</strong>g <strong>of</strong> Carpet Materials) achieved remarkable<br />

technological results. Dur<strong>in</strong>g <strong>the</strong> €5.5 million project a closed<br />

loop system for recycl<strong>in</strong>g <strong>of</strong> carpet materials was developed.<br />

<strong>The</strong> system had huge potential: <strong>the</strong> partners <strong>in</strong>volved <strong>in</strong><br />

RECAM (research <strong>in</strong>stitutions <strong>and</strong> producers <strong>of</strong> carpets <strong>and</strong><br />

chemicals) estimated that it would be technologically possible<br />

to recycle more than one million tonnes <strong>of</strong> European carpet<br />

waste per year. A life cycle assessment study also looked very<br />

promis<strong>in</strong>g: implementation <strong>of</strong> <strong>the</strong> complete RECAM system<br />

would reduce all <strong>the</strong> exam<strong>in</strong>ed environmental effects by more<br />

than 50% compared to current practice at <strong>the</strong> time. <strong>The</strong> system<br />

<strong>in</strong>cluded collection <strong>of</strong> carpet waste, automated equipment<br />

for sort<strong>in</strong>g (based on near-<strong>in</strong>frared technology), mechanical<br />

recycl<strong>in</strong>g <strong>of</strong> wool <strong>and</strong> polypropylene <strong>and</strong> mechanical <strong>and</strong><br />

chemical recycl<strong>in</strong>g <strong>of</strong> polyamide.<br />

<strong>the</strong> total amount <strong>of</strong> carpet waste l<strong>and</strong> filled <strong>in</strong> <strong>the</strong> USA by<br />

more than 100,000 tonnes per year. However, <strong>in</strong> <strong>the</strong> autumn<br />

<strong>of</strong> 2001 <strong>the</strong> commercial plant <strong>in</strong> <strong>the</strong> USA closed <strong>in</strong>def<strong>in</strong>itely<br />

due to higher than expected production costs comb<strong>in</strong>ed<br />

with unfavourable bus<strong>in</strong>ess <strong>and</strong> economic conditions. From<br />

an environmental <strong>textiles</strong> perspective <strong>the</strong> RECAM project was<br />

a huge technological success, with significant environmental<br />

benefits, but under current economic conditions <strong>the</strong> project<br />

has so far failed to be pr<strong>of</strong>itable <strong>and</strong> <strong>the</strong>refore susta<strong>in</strong>able E3 .<br />

As a sp<strong>in</strong>-<strong>of</strong>f from <strong>the</strong> RECAM project a $100 million<br />

commercial-scale plant was established <strong>in</strong> Augusta, USA.<br />

<strong>The</strong> plant was designed for mechanical <strong>and</strong> chemical<br />

recycl<strong>in</strong>g <strong>of</strong> polyamide carpet waste to recover <strong>the</strong> monomer<br />

caprolactam. It was anticipated that <strong>the</strong> facility would reduce<br />
