Natural vs. Synthetic
Why Natural Materials Are Key to Sustainable Fashion's Future:
As the fashion industry shifts towards more eco-friendly practices, the debate between natural and synthetic materials has become a focal point in the sustainability conversation. With an increasing awareness of the environmental damage caused by the fashion sector, especially by fast fashion, more consumers and brands in the UK are questioning the materials used in their clothes.
The decision between natural and synthetic fabrics is more than just a personal preference for style or comfort—it directly impacts the environment. In this blog post, I’ll explore the differences between natural and synthetic materials, their environmental impact, and why embracing natural materials is essential for the future of sustainable fashion.
What Are Natural and Synthetic Fabrics?
Before diving into the environmental implications, it's important to understand the fundamental differences between natural and synthetic fabrics:
Natural fabrics are made from fibres derived from plants, animals, or minerals. Common examples include cotton, linen, wool, silk, and hemp. These materials are renewable, biodegradable, and have been used for centuries in clothing production.
Synthetic fabrics, on the other hand, are man-made and are typically derived from petrochemicals. Examples include polyester, nylon, acrylic, and spandex. These materials are cheaper to produce on a mass scale, but they come with significant environmental drawbacks, including being non-biodegradable and contributing to plastic pollution.
Why Natural Materials Are Key to Sustainable Fashion
When it comes to sustainability, natural materials have a clear edge over synthetics for several reasons. Here’s why natural fibres should be a core part of the sustainable fashion movement:
1. Biodegradability
One of the most significant environmental benefits of natural fabrics is their ability to biodegrade. When natural fibres like cotton, linen, wool, and silk are discarded, they decompose back into the earth over time, leaving no harmful traces behind. In the right conditions, they can break down within a few months to a couple of years, depending on the material.
In contrast, synthetic fabrics like polyester, nylon, and acrylic take hundreds of years to degrade. These materials are essentially forms of plastic, and as they decompose, they break down into microplastics—tiny, harmful particles that infiltrate ecosystems, waterways, and even our food supply. Microplastic pollution has become a growing concern in the UK, and the fashion industry is a major contributor. By opting for natural materials, we can reduce the long-term waste that synthetic fibres create and lessen the environmental burden of clothing disposal.
2. Renewable Resources
Natural materials are typically derived from renewable resources, such as plants and animals, that can be replenished naturally. Cotton, linen (made from flax), hemp, and wool are examples of materials that can be sustainably sourced if grown or produced under the right conditions. On the other hand, synthetic materials are made from fossil fuels, primarily petroleum, a non-renewable resource. The production of synthetic fibres is energy-intensive and contributes to climate change through greenhouse gas emissions. As the UK and the global community strive to reduce dependence on fossil fuels, turning to natural materials can help decrease the fashion industry's carbon footprint.
3. Lower Environmental Impact During Production
The environmental impact of textile production varies greatly between natural and synthetic fibres:
Natural fibres such as hemp, linen, and organic cotton have a lower environmental impact during production, especially when grown using sustainable farming practices. Organic cotton, for example, uses far less water and harmful chemicals compared to conventional cotton farming. Hemp and linen require fewer pesticides, less water, and are highly durable, making them excellent options for eco-friendly clothing.
Synthetic fibres, however, are produced through a highly energy-intensive process. Manufacturing polyester, nylon, and other synthetics releases large amounts of greenhouse gases and toxic emissions. Additionally, the production of these materials is often reliant on harmful chemicals, which can have detrimental effects on both the environment and the workers in production facilities.
By choosing natural fibres that are grown and processed with sustainability in mind, the fashion industry can significantly reduce its environmental footprint and ensure a cleaner, greener production process.
4. Avoiding Microplastic Pollution
One of the less visible but increasingly concerning aspects of synthetic fabrics is their contribution to microplastic pollution. Every time synthetic clothes are washed, tiny plastic fibres—known as microfibres—are shed into the water system. These microfibres are too small to be filtered out by standard wastewater treatment plants, meaning they end up in rivers, lakes, and oceans.
Research has shown that a single load of laundry can release thousands of microplastic fibres, which accumulate in marine environments and cause harm to aquatic life. A recent study found that 35% of all microplastics in the ocean come from synthetic textiles, making fashion one of the leading causes of plastic pollution.
In the UK, organisations like The Microfibre Consortium are working to tackle this issue by developing solutions to reduce fibre shedding. However, switching to natural fibres offers a direct way for both consumers and brands to avoid contributing to this pollution.
Challenges of Natural Materials in Fashion
While natural materials offer many sustainability benefits, it's important to acknowledge the challenges and trade-offs involved. Not all natural fibres are created equal, and some can have significant environmental impacts if not produced sustainably. For example:
Conventional cotton farming is known for being water-intensive and heavily reliant on pesticides and fertilisers. However, organic cotton presents a more sustainable alternative, using fewer chemicals and less water.
The production of animal-based materials like wool and leather can raise ethical concerns related to animal welfare and farming practices. Sustainable alternatives like plant-based leather (made from pineapple, mushrooms, or cactus) are emerging to provide cruelty-free options.
To ensure that natural materials remain part of a truly sustainable fashion future, it’s essential for brands and consumers to support certified sustainable practices, such as organic farming, fair trade production, and ethical sourcing.
How UK Consumers Can Support Sustainable Materials
For UK consumers, making informed choices about the fabrics in their wardrobe is a crucial step toward reducing the environmental impact of fashion. Here are some practical ways to prioritise natural materials and make more sustainable fashion choices:
Look for organic certifications: When shopping for natural materials like cotton, seek out brands that use organic cotton, which is grown without harmful pesticides and with reduced water consumption. Certifications like GOTS (Global Organic Textile Standard) can help identify genuinely sustainable products.
Opt for less resource-intensive fibres: Explore alternatives to conventional cotton by choosing fabrics like hemp, linen, or bamboo. These fibres require fewer resources and are often more durable, meaning they last longer and reduce the need for frequent replacements.
Choose wool over synthetics: When it comes to winter wear, wool is a natural, renewable, and biodegradable alternative to synthetic fibres like polyester or acrylic. UK-based brands like Finisterre use sustainably sourced wool in their outdoor wear, ensuring both performance and eco-friendliness.
Avoid fast fashion: Synthetic materials dominate fast fashion, which is built on the rapid production of cheap, low-quality clothing. Instead, invest in timeless, high-quality pieces made from sustainable natural fibres that will last for years and reduce your overall clothing consumption.
As the UK fashion industry continues to evolve towards sustainability, choosing natural materials over synthetics is a powerful way to reduce the environmental impact of clothing production and consumption. While synthetic fibres like polyester and nylon may offer affordability and convenience, their long-term effects on the planet, including microplastic pollution and reliance on fossil fuels, cannot be ignored.
Natural fibres, particularly those produced using sustainable and ethical methods, offer a renewable, biodegradable, and lower-impact alternative. By embracing natural materials and supporting sustainable practices, UK consumers and brands can play a crucial role in shaping the future of fashion—one that values the planet as much as it values style.
