Sustainable Product

Being a forward looking company that wants to continue making iconic products in the future, G-Star acknowledges the need to look into sustainable solutions. Only when creating products with minimal environmental impact, are we able to continue as a successful company. We therefore carefully consider the materials used for our products.

We can make a big move towards minimising the environmental impact of our products by looking for materials that contribute to a more sustainable future without compromising on quality, comfort and design. Consequently, we aim to gradually increase the use of sustainable materials in our collection.

G-Star considers the following materials sustainable:

Recycled Cotton

Organic Cotton

In Conversion Cotton

Organic Flax (Linen)

Conventional Flax (Linen)

Mechanically Recycled Nylon

Mechanically Recycled Polyester

Chemically Recycled Polyester

Recycled Wool

Ramie

Organic Hemp

Conventional Hemp

Tencel® (Lyocell product from Lenzing)

Nettle

PLA

Source: MADE-BY Fibre Benchmark

We mostly use organic cotton, recycled cotton, recycled polyester and Tencel® in our products, accounting for at least 9.5% of our collection in 2012. The exact amount of sustainable materials in our collection will be published in June 2013 when our first Scorecard will appear on the website of MADE-BY. The Scorecard will be published each year and will show our social and environmental progress as verified by MADE-BY.

Sustainable materials often require more complex production processes and longer lead-times. Because it concerns innovative materials that are less widely available than conventional ones, fitting them into our supply chain is a challenge that we take on in close cooperation with our suppliers. 

2.1 - Characteristics sustainable materials

Organic Cotton

Organic cotton is cultivated without chemical pesticides and synthetic fertilisers, making it an environmentally friendly alternative to conventional cotton. In addition, organic crops are grown from non-genetically modified seeds and the majority of global production is rain fed as opposed to irrigated, consuming significantly less water.

Recycled Cotton

Recycled cotton is produced from post-consumer or post-industrial waste material. The use of recycled cotton generates savings on raw materials, water, chemicals and energy.

In Conversion Cotton

Cotton in conversion is grown on land that has only recently been converted to organic cultivation (less than 2 to 3 years). Therefore, although no chemical pesticides and synthetic fertilisers are being used, residues may still be found in the soil and the cotton cannot be certified as organic cotton yet. Cotton in conversion is sold to support organic farmers and to stimulate the development of organic cotton.

Tencel® (Lyocell product from lenzing)

Lyocell is a manmade natural fibre of cellulose extracted from eucalyptus wood pulp.  Eucalyptus trees grow rapidly and can thrive on poor quality land without the need for irrigated water or synthetic pesticides. The Eucalyptus trees harvested for Tencel, the Lyocell fibre from the fibre producing company Lenzing, come from FSC (Forest Stewardship Council) certified farms.

Hemp and Organic Hemp

Hemp is in general a high yield, low maintenance crop that is ideal for rotation. Although it requires limited amounts of fertilisers, it does not require pesticides, herbicides or irrigation water. 

Organic certified hemp is grown without the use of synthetic fertilisers and retted to extract the fibre without the use of chemicals.

Linen and Organic Linen

Flax (the plant from which linen fibres are extracted) is a fast growing, renewable crop which is ideal for rotation. It requires relatively low amounts of pesticides and fertilisers.

Organic certified flax is grown without the use of synthetic fertilisers and retted to extract the fibre without the use of chemicals.

Mechanically and Chemically Recycled Polyester and Polyamide (Nylon)

Polyester and Polyamide are manmade synthetic fibres made from crude oil, a non-renewable resource. The process of refining oil, creating a polymer, extruding and spinning the fibre is energy intensive and uses large amounts of water. Recycled polyester and nylon are produced from post-consumer or post-industrial waste materials such as PET plastic bottles, apparel or nylon fishing nets; material that would otherwise have been sent to landfill or for incineration. It prevents the further extraction of a non-renewable resource.

Mechanical recycling utilises energy to re-melt the waste material. However, the resulting CO² emissions are much smaller than those produced from the manufacture of virgin fibre. Chemical recycling utilises chemical additives and involves more energy. 

Recycled Wool

Recycled wool is made from post-consumer or post-industrial wool waste. As this process makes the wool fibres shorter, it is often blended with other fibres such as virgin wool or cotton to increase the average fibre length.

Nettle

Nettle is a natural fibre derived from the nettle plant that is rainfed as opposed to irrigated and grows easily without pesticides. The process to extract the fibre does not need any additional chemicals, enzymes or other auxiliaries. It makes use of the natural enzymes existing in the nettle plants itself.

Ramie

Ramie is a sustainable bast fibre, similar to flax. It is one of the strongest natural fibres and can be up to 8 times stronger than cotton. However, the processing of ramie requires the use of chemicals to de-gum the fibre.

PLA

PLA, short for polylactic acid, is a sustainable alternative to fibres made from non-renewable crude oil, since it can be produced with the use of renewable agricultural by-products such as corn starch, sugar or wheat. However, processing the fibre requires a relatively high amount of energy and pesticides and fertilisers are used in intensive agriculture of corn, sugar or wheat.

2.2 - RAW Sustainable

In accordance with G-Star’s nature to push boundaries by constantly developing new products, the RAW Sustainable programme was set up. This programme is entirely made of innovative sustainable fibres.

Currently, the RAW Sustainable programme consists of three lines, each with its own characteristics and recognisable label:

·         RAW Nettle

Nettle plants require much less water and chemicals than conventional cotton. G-Star therefore combines organic cotton with nettle plant fibres to create sustainable denim with a reduced environmental footprint.

Materials: Any blend of nettle and certified organic cotton.

·         RAW Recycled

RAW Recycled blends post-consumer denim with organic cotton to give a second life to the material. The use of recycled cotton generates savings on raw materials, water, chemicals and energy.

Materials: Any blend of recycled cotton and certified organic cotton.

·       RAW Organic

RAW Organic is made of organic cotton that is cultivated without chemical pesticides and fertilisers, making it an environmentally friendly alternative to conventional cotton.
Materials: 100% certified organic cotton.

Next to the RAW Sustainable programme we also gradually increase the use of sustainable materials in the rest of our collection by replacing conventional cotton with more environmentally friendly fabrics such as organic cotton, recycled cotton and Lyocell (Tencel).

2.3 - Textile Exchange membership

Textile Exchange membership

According to the Textile Exchange Farm and Fibre Report 2010, organic cotton still represents only a small fraction of all cotton produced, counting for 1.1% of global cotton production in 2010. Access to organic cotton and other sustainable materials is still a significant barrier to increasing the use of these materials in the fashion industry.

Textile Exchange is a non-profit membership based organisation that works to increase the global market for sustainable fibres, with a special focus on stimulating farming and trading of organically grown cotton.

G-Star is a member of Textile Exchange and supports the efforts of this organisation to minimise the harmful impacts of the global textile industry and maximise its positive effects. For more information about Textile Exchange, please visit www.textileexchange.org.

2.4 - Sustainable washing and manufacturing

We are working with our suppliers on various innovative dyeing and finishing processes, including ozone bleaching, laser treatments and natural tanning of leather, that have a reduced social and environmental impact:

Lexicon Denim 
Styles in Lexicon Denim DK Aged fabric are made using innovative dyeing and finishing processes that generate a big reduction in water (up to 95%), energy and chemical usage in comparison to conventional processes. In addition, these denims are dried in the air with a rotating system that is able to dry 40.000 jeans in 25 minutes, instead of using conventional dryers. Lexicon denim is available in the G-Star collection since the Spring/Summer 2013 collection.

Stover Nylon 
As of the Autumn/Winter 2012 collection, several coats are made from a special compactly woven fabric called Stover Nylon. With an innovative weaving technique, the fabric is woven into a tight compact weave. This generates a high degree of water repellency without the need for chemicals.

Sandblasting Ban
We publically announced in November 2010 to ban the use of sandblasting in our production process and to stop the sale of sandblasted products as of end 2011. Sandblasting involves the use of pressurised air to spray sand against garments to abrade the fabric and achieve a ‘worn and faded look’. When the proper measures and precautions are in place, sandblasting is a safe technique. Without proper measures and precautions in place, sandblasting can cause serious illnesses to the workers that practice this technique due to the exposure to silica dust (a compound found in sand). From the very beginning that G-Star used sandblasting, strict health and safety requirements were set and we looked into alternative techniques to get the same look for our denim. To prevent any residual risks, we publically announced in November 2010 to ban the use of sandblasting in our production process and to stop the sale of sandblasted products as of end 2011. All our suppliers have been specifically informed about the ban on sandblasting. Monitoring of compliance with the sandblasting ban is included in our regular compliance process.
