How to Make Viscose a Sustainable Choice for You

by

Navigating the complex world of textile sustainability can be a minefield of jargon, greenwashing, and conflicting information. At the heart of this complexity lies viscose, a semi-synthetic fiber derived from natural sources, often positioned as an eco-friendly alternative to purely synthetic fabrics. However, the reality is far more nuanced. The journey of viscose, from a tree to a garment, is fraught with environmental and social challenges, but it also presents a significant opportunity for positive change. Making viscose a sustainable choice for you is not about avoiding it entirely; it’s about becoming an informed and deliberate consumer who understands the difference between the good, the bad, and the truly transformative. This guide will equip you with the knowledge and practical strategies to confidently choose sustainable viscose, ensuring your fashion choices contribute to a healthier planet and a more ethical industry.

The Viscose Problem: Unveiling the Hidden Environmental Costs

Before diving into solutions, it’s crucial to understand why conventional viscose is problematic. The core issue lies in the manufacturing process, which has remained largely unchanged for decades. This “open-loop” system is a major contributor to environmental degradation.

Deforestation and Unsustainable Sourcing: The raw material for viscose is wood pulp. While trees are a renewable resource, the sheer scale of global viscose production has led to the deforestation of ancient and endangered forests. Vast areas of biodiverse ecosystems are cleared to make way for monoculture tree plantations, which deplete soil nutrients and reduce natural habitats. A significant portion of the world’s viscose is linked to unsustainable forestry practices, leading to habitat destruction and the displacement of indigenous communities.

Chemical Pollution and Worker Health: The transformation of wood pulp into a soft, drapey fabric is a chemical-intensive process. The open-loop system involves dissolving the wood pulp using harsh chemicals like carbon disulfide and sodium hydroxide. These toxic chemicals are often released as untreated wastewater and air emissions into local ecosystems, contaminating rivers, lakes, and the air. This pollution not only devastates local flora and fauna but also poses severe health risks to factory workers and nearby communities, with links to nerve damage, birth defects, and other serious health issues.

Water and Energy Consumption: The conventional viscose manufacturing process is a heavy consumer of both water and energy. From the cultivation of the trees to the chemical baths and washing stages, vast quantities of water are used. The energy required to heat and run the machinery is typically sourced from non-renewable fossil fuels, contributing to a significant carbon footprint.

How to Identify Truly Sustainable Viscose

The good news is that not all viscose is created equal. A new generation of producers and brands is actively working to mitigate these environmental impacts. Your role as a consumer is to learn how to spot these improved alternatives. The key lies in understanding the certifications, the manufacturing processes, and the branding that signifies a commitment to sustainability.

Closed-Loop Production: The Game-Changer: This is the most critical distinction. Closed-loop manufacturing is a modern, responsible approach where the chemicals used to dissolve the wood pulp are captured, purified, and reused in the production cycle. This process dramatically reduces chemical pollution by up to 95%, minimizes wastewater, and lowers energy consumption. Brands using a closed-loop system will proudly highlight this on their product descriptions or sustainability reports.

  • Concrete Example: A brand’s product page might say, “Our blouse is made from Tencel™ Lyocell, a fiber produced in a closed-loop system where 99% of the solvent is recovered and reused.” This is a clear indicator of a sustainable choice.

Certifications to Look For: Certifications are your most reliable tool for cutting through greenwashing. They are third-party verifications that a product meets specific environmental and social standards. Look for these logos and phrases on garment labels and brand websites:

  • Forest Stewardship Council (FSC) and Programme for the Endorsement of Forest Certification (PEFC): These certifications guarantee that the wood pulp used to make the viscose comes from responsibly managed forests, not from ancient or endangered forests. They ensure that forestry practices are socially beneficial, environmentally appropriate, and economically viable.
    • Actionable Advice: When shopping, search for terms like “FSC-certified viscose” or “viscose from certified sustainable forests.” If a brand makes a vague claim like “from responsibly sourced trees,” ask them for proof of their certification.
  • EU Ecolabel: This is a comprehensive certification for products with a reduced environmental impact throughout their lifecycle. For viscose, it ensures lower air and water pollution, reduced chemical usage, and resource efficiency during production.
    • Actionable Advice: Look for the EU Ecolabel flower on the product tag. This is a robust indicator of a higher standard of environmental performance.
  • OEKO-TEX Standard 100: This certification focuses on the safety of the final product for human health. It tests for harmful substances and chemical residues. While it doesn’t guarantee a sustainable manufacturing process, it does ensure the garment is free from a long list of harmful chemicals.
    • Actionable Advice: The OEKO-TEX label is very common. While not a definitive marker of an eco-friendly process, it’s a good baseline to ensure the product is safe to wear.

The Best Sustainable Viscose Alternatives

The market now offers several superior forms of viscose that embody these sustainable principles. Knowing their names and specific benefits will help you make a targeted and effective choice.

Lenzing Ecovero™ Viscose: This is a branded, eco-responsible viscose fiber produced by the company Lenzing. It is a leading example of closed-loop technology.

  • Key Features: Ecovero™ is made from certified renewable wood sources (FSC or PEFC-certified) and uses a closed-loop production process. Compared to generic viscose, its production uses up to 50% less water and emits up to 50% less CO2. It is also biodegradable and compostable.

  • Concrete Example: Instead of buying a generic viscose dress, seek out one from a brand that explicitly states it uses “Lenzing Ecovero™.” This is a reliable marker of a sustainably produced garment.

Tencel™ Lyocell: Tencel™ is a brand name for lyocell, a type of regenerated cellulose fiber. While not technically viscose (it uses a different, less-toxic solvent), it’s often grouped with it due to its similar drape and feel, and it represents the pinnacle of sustainable cellulosic fibers.

  • Key Features: Tencel™ is also made from sustainably sourced wood pulp, typically eucalyptus, which requires little water and no pesticides to grow. The closed-loop process used to produce Tencel™ is highly efficient, with 99.8% of the solvent recovered and reused. It is exceptionally soft, durable, and biodegradable.

  • Concrete Example: A brand might sell a “Tencel™ Lyocell” shirt, marketing it as an eco-friendly alternative to silk. The Tencel™ name itself is a sign of a high-quality, sustainable choice.

Refibra™ Technology: This is an innovative circular economy approach developed by Lenzing that combines wood pulp with recycled cotton scraps from garment factories.

  • Key Features: By incorporating post-industrial waste, Refibra™ technology reduces the need for virgin materials and helps tackle textile waste. It is a form of Ecovero™ or Tencel™ with an added layer of circularity.

  • Concrete Example: You might see a product labeled “Lenzing Ecovero™ with Refibra™ technology.” This signals that the garment is not only made sustainably but also includes recycled content, further minimizing its environmental footprint.

How to Shop for Sustainable Viscose: Your Action Plan

Now that you know what to look for, here is a clear, step-by-step action plan for making sustainable viscose choices in your own life.

Step 1: Check the Label, and Then the Website: Don’t just rely on a brand’s claim of “eco-friendly.” Look for the specific names and certifications discussed above on the garment’s label. If the label is vague or only says “viscose,” go to the brand’s website. Search for their sustainability page, fabric information, or specific product details. A brand that is truly committed to sustainability will be transparent and will provide this information readily.

  • Concrete Example: You’re in a store and see a dress labeled “viscose.” It has a good drape, but you’re not sure if it’s a sustainable choice. You pull out your phone and go to the brand’s website. On their “Sustainability” page, you find a detailed breakdown of their materials, which states, “All of our viscose is sourced from Lenzing and is Ecovero™ certified.” You can now make an informed purchase.

Step 2: Ask Brands Direct Questions: Don’t be afraid to engage with a brand’s customer service. Your questions as a consumer are powerful and signal a demand for transparency and accountability.

  • Concrete Examples:
    • “What percentage of your viscose is certified by FSC or PEFC?”

    • “Do your viscose suppliers use a closed-loop or open-loop production system?”

    • “Can you provide information on the certifications for the viscose used in this specific product?”

    • A brand that provides clear, detailed answers is one you can trust. A brand that gives a vague or non-committal response may be hiding something.

Step 3: Prioritize Brands with Strong Sustainability Credentials: Some brands have built their entire business model around ethical and sustainable practices. Seeking out these companies first simplifies the shopping process and ensures you’re supporting a business that aligns with your values.

  • Concrete Examples: Instead of Browse a fast-fashion site with a massive viscose selection, you can start your search with a list of brands known for using Lenzing fibers. Many ethical fashion directories and articles can help you find these companies. You’ll find that these brands often use Ecovero™ or Tencel™ as their standard for viscose-like fabrics.

Extending the Life of Your Viscose Garments

Choosing sustainable viscose is only half the battle. How you care for your clothes throughout their lifespan has a significant impact on their overall sustainability. Viscose, even the eco-friendly variety, requires specific care to prevent damage and extend its life.

Washing Wisely: Viscose fibers can become fragile when wet. The wrong washing method can lead to shrinkage, stretching, or pilling.

  • Concrete Examples:
    • Hand Wash is Best: Fill a basin with cold water and a mild detergent. Gently submerge the garment and swish it around. Avoid twisting or wringing.

    • Machine Wash with Caution: If the care label allows it, use a cold, delicate cycle. Place the item in a mesh laundry bag to protect it from the machine’s agitation and from rubbing against other clothes.

    • Avoid Fabric Softeners: These can leave a residue on the fibers.

Drying and Ironing: High heat is the enemy of viscose. A dryer can cause permanent shrinkage, and a hot iron can scorch the delicate fibers.

  • Concrete Examples:
    • Air Dry is Key: After washing, gently press out excess water without twisting. Lay the garment flat on a clean towel or hang it on a padded hanger to air dry. Reshape it gently while damp.

    • Cool Ironing: If you must iron, do so on a low heat setting, preferably while the garment is still slightly damp. Iron on the inside of the garment to protect its finish.

Storage: Proper storage prevents stretching and keeps the garment in good condition.

  • Concrete Example: Fold your viscose items and store them in a drawer or on a shelf rather than hanging them. This prevents the fabric from stretching out over time, especially at the shoulders.
