Is Bamboo a Sustainable Fabric?

You might know bamboo as that hardy, fast-growing plant that’s used in everything from construction to cuisine, but its use in the fabric industry is carving out a new chapter for the material. Soft, drapable, and widely touted for its comfort, bamboo fabric is often marketed as an eco-conscious choice, but is it as sustainable as you’re led to believe?

One of the plant’s plus points is that it’s often grown with little to no use of pesticides. Since bamboo can thrive without fertilizers and with little water, it sets a pretty high standard for sustainability. However, the sustainability story doesn’t stop at the bamboo farm. To judge the overall environmental impact of bamboo textiles, you need to follow the journey all the way to your closet.

I wish I could give you a clear answer on whether or not bamboo is a sustainable material. The reality is that some bamboo textiles are sustainable and others are not, depending on the processes used to turn the plant into soft fibers. However, since bamboo has a reputation as being eco-friendly, a lot of brands will use the cheapest and least sustainable types of bamboo to greenwash the overall sustainability of their clothing and fabric lines.

What is Bamboo Fabric and is it sustainable?

Bamboo fabric is a textile made from the pulp of bamboo grass. It is marketed as an eco-friendly material due to bamboo’s fast growth rate and ability to thrive without pesticides. But is it as sustainable as it seems?

Bamboo is cut down and undergoes a crushing process. The crushed bamboo is soaked in a solution, often containing harsh chemicals, to break down the fibers. The resulting mush is pressed to extract bamboo cellulose. The cellulose is forced through spinnerets to create the yarns that can be woven into various types of fabric.

Though bamboo fabric has potential for sustainability, current mainstream production methods raise environmental red flags. The process of breaking down bamboo and turning it into usable fibers usually uses a rayon manufacturing process that involves extremely toxic solvents. 

Not only do these chemicals (such as carbon disulfide) pose a major risk to workers in the textile production, but they are also released into the surrounding waterways polluting them and causing a whole lot of damage to the environment and the people living in the surrounding communities.

With this in mind, it is important to point out that some manufacturers are working towards more eco-friendly alternatives and safer methods. Bamboo modal, for example, uses less toxic chemicals in the production and uses a closed loop system that avoids polluting neighboring waterways and communities. So, the sustainability of the bamboo fabric really comes down to the way it was produced. 

There have also been some concerns about deforestation that’s occurred due to the rise of bamboo popularity. In some regions, natural forests are being cleared to make way for bamboo plantations. Sustainable management and certification schemes, like the Forest Stewardship Council (FSC), can help ensure that bamboo comes from responsibly managed forests that provide environmental, social, and economic benefits.

Pros of Bamboo Fabric

As a fast-growing plant, bamboo can be sustainably harvested, and it requires less water and pesticides than conventional cotton. Additionally, bamboo fabric is lauded for its softness, moisture-wicking properties, and breathability, which make it comfortable to wear. When manufactured with sustainability in mind, bamboo is a fantastic fabric to use.

• Biodegradable Nature: One of the significant benefits of bamboo fabric is its biodegradable nature. After you discard your bamboo clothing, it can decompose without leaving behind harmful residues, which helps reduce the waste impact on the environment.
• Fast Growing: Bamboo is an incredibly fast-growing plant, capable of reaching maturity in as little as three to five years. This rapid growth means it can be replenished quickly, making it a highly sustainable resource for fabric production.
• Water usage: Bamboo’s water requirements are minimal. It thrives with rainwater and does not rely heavily on additional water sources. This characteristic makes it a more sustainable option compared to plants that require large amounts of irrigated water, such as cotton.
• Fertilizers and pesticides: bamboo does not need synthetic fertilizers or pesticides for growth. Its natural resistance to pests minimizes the need for chemicals that could otherwise harm the environment.
• Softness and Comfort: Your comfort is not disregarded with bamboo fabric. Notably, it is recognized for its softness, which makes it comfortable to wear.
• Moisture-Wicking Properties: If you lead an active lifestyle or seek comfort in various climates, you’ll appreciate bamboo fabric’s moisture-wicking properties. It draws moisture away from the skin, helping to keep you dry and comfortable.

Cons of Bamboo Fabric

Unfortunately, the current state of bamboo textile production means that bamboo is not a wholly sustainable fabric. Many of the marketing surrounding the material can come down to greenwashing, plain and simple. Your understanding of its eco-friendliness should include awareness of the environmental costs and impacts on land use.

• Manufacturing methods: The creation of bamboo rayon requires chemicals like sodium hydroxide and carbon disulfide, which can be harmful to both workers and the environment when not managed properly. Despite bamboo’s rapid growth rate, the transformation of raw bamboo into fabric isn’t always an eco-friendly process. 
• Greenwashing: Some labels may suggest that bamboo fabric is completely natural and green, while omitting details about the chemical processes involved. 
• Deforestation concerns: Finally, the expansion of bamboo farms may lead to deforestation as more forests are cut down to make way for bamboo plantations, potentially threatening biodiversity and carbon sequestration benefits provided by natural forests.

Certifications and What to Look For

When you’re exploring bamboo fabrics, certifications like OEKO-TEX and FSC (Forest Stewardship Council) are good indicators of sustainability. These certifications provide assurances that the products you purchase are produced responsibly.

OEKO-TEX certified bamboo fabrics are tested to ensure they are free from harmful substances. When a product carries this label, you can be confident that it’s safe for your skin and health.

FSC certification focuses on the source of the bamboo. It confirms that the bamboo was harvested sustainably from forests that are managed with consideration for the environment, wildlife, and local communities.

To ensure ethical manufacturing practices, look for transparency in how a company reports its production processes. Ensure they commit to ethical labor and transparent production chains.
