Reduce your environmental impact
Taking environmental impacts into consideration during the production and manufacturing process is known as eco-design. Eco-design not only improves the environmental outcomes, it can also reduce your costs in the long-term.
What are the impacts?
The production, manufacturing, transportation and use of textiles for fashion and interior furnishing applications can include:
- yarns (both natural and synthetic fibres)
- paper patterns
The main environmental impacts arise from material selection and use, manufacturing processes, the dyes used to print fabrics, and the ethical issues around the human labour used to create garments.
Natural and synthetic fibres are the two main types of fibres used to make materials. Natural, or organic fibres include cotton, wool, hemp and bamboo, while synthetic or man-made fibres include polyester, nylon, spandex and acrylic.
Minimising the impact of materials
- when selecting materials, consider how the product will be used, and match durability with garment type.
- washing can also contribute a considerable amount of environmental impacts to a garment. Choosing fabrics that require less detergents and can be cleaned in cold water will reduce environmental impacts.
There are a variety of production techniques used in the manufacture of fabrics, including:
- wet treatment
Apart from the energy and water used during manufacturing, there are also inevitable waste products – such as waste water – that may be contaminated with chemical products.
The manufacturing of garments or soft furnishings from prepared fabrics can result in off-cuts.
Minimising the impact of manufacturing
- Waste can be minimised through good pattern design and cutting techniques.
- To reduce the impacts associated with manufacturing, choose manufacturers who employ cleaner production, or have environmental management certification.
Inks and dyes
Most fabrics go through a process of wet treatments, such as:
Many of these processes require chemicals and dyes that are potential environmentally hazardous waste products, contribute to climate change, and may release Volatile Organic Compounds (VOCs) into the atmosphere.
Minimising the impact of inks and dyes
- Avoid inks and dyes that contain toxic heavy metals (for example, cadmium and beryllium) and preference natural dyes made from plant materials.
- Look for dye manufacturers who recycle their waste.
As most garments are lightweight and ambient, large quantities can be shipped at a time, making transport less of a priority with regard to environmental impacts.
Heavy vehicles such as trucks also contribute considerably to climate change through their carbon dioxide (CO2) emissions.
Minimising the impact of transportation
- Always preference shipping over airfreight for international transportation, and for ground transport preference rail over road.
Care instructions and labelling
The care instruction label provides an opportunity for your customers to minimise the environmental impacts associated with a product's life.
Washing in hot water requires energy to be used and so contributes to climate change. Garments that require harsh detergents for washing pollute wastewater.
Minimising the impact by labelling
- Items that can be washed effectively in cold water and with a minimum of detergents will have a reduced impact throughout their life – where possible, always indicate cold wash on your care instruction labels.
Wider ethical issues
The fashion industry is often criticised for the use of unethical labour practices, particularly in the production of garments and footwear.
Minimising unethical labour practices
- There has been a rise in consumer labels that promote 'ethical' fashion, such as the 'no sweat', 'fair trade' or 'sweatshop free' brands. These have been strong and successful communication tools for consumers, and are worth investigating as options for your products.
- If you are producing offshore, check the working conditions of manufacturing operations and request third party verification.
Sustainable fashion design checklist
1. Identify key outcomes in the design brief and concept
- how the pattern will be laid out on flat fabric
- the amount of waste generated
- whether the garment can be constructed in a different way to reduce waste
- exploring ways of reducing labour costs in the manufacturing process, such as 3D knitting.
2. Select sustainable materials
- Consider the life of the garment and select the right textile to minimise wear, tear, stains or the need for specialist cleaning. Natural fibres such as cotton and bamboo have a lower environmental impact than synthetic fibres such as spandax and polyester.
- Select inks and dyes that are non-toxic, natural or vegetable-based.
- Consider composite approaches in your material selection – for example, research shows that 50/50 cotton-polyester mixes are likely to last twice as long as 100 percent cotton sheets and may have a significant reduction in environmental impacts associated with laundering.
- If you adopt sustainable practices in the selection of materials, consider having your products certified organic that will generate goodwill with customers who support sustainable living.
3. Minimise waste during pattern making
- Think about how you can construct the garment in a different way to reduce waste, such as offcuts and end-of-roll.
- Select textiles that have a repeat pattern with no beginning or end, so that the entire roll of fabric can be used.
- When garments are constructed, waste is usually a by-product, so think about how you can reuse or recycle the waste and offcuts.
4. Opt for ethical garment construction
- During the production process, use textile workers that work under ethical conditions.
- Garment labels communicating information on garment use, care and recycling can help consumers to avoid discarding it prematurely and minimise environmental impact during washing.
5. Reduce waste in packaging
- Think about the way you package the finished product and if you could reduce the amount of packaging used.
- Find a local service to recycle packaging.
