A viral Instagram post with over 14,000 reposts claims that bamboo fabric is not eco-friendly and may even be harmful to the environment:
The images argue that while bamboo “in its natural form uses low water, grows without pesticides, and is breathable,” the problem is that “99% of manufacturers use a highly toxic chemical to break the plant down into a fiber.” They further claim that “almost all bamboo clothing/textiles today are not actually bamboo” but are “considered rayon/viscose,” produced using the chemical carbon disulfide, which has been “linked to nerve damage, heart disease, reproductive harm, and mental health effects,” and that this process “continues to pollute the communities around manufacturing facilities.” The post concludes that bamboo is a “Frankenstein-type creation, full of chemicals and not much better than plastic.”
Looking into the claim, we found that it is true that most bamboo fabric on the market is made using the viscose (rayon) process. The U.S. Federal Trade Commission (FTC) has clarified that products marketed as “bamboo” textiles are typically rayon and must be labelled as “rayon made from bamboo,” because the fibre is chemically transformed during manufacturing.
In that process, bamboo cellulose is chemically dissolved using carbon disulfide and regenerated into fibre. Carbon disulfide is a hazardous chemical and has historically been associated with serious occupational health harms to workers exposed to carbon disulfide fumes in poorly regulated factories. These harms include but are not limited to nerve damage (causing memory problems, tremors, mood changes), heart disease, and reproductive problems.
However, the claim that “99% of manufacturers” use this process is not supported by any publicly available industry-wide data. While viscose dominates the bamboo textile market, the specific statistic appears unverified.
The statement that bamboo textiles are “not actually bamboo” is also misleading. Bamboo viscose is derived from bamboo cellulose, though it is chemically transformed and therefore classified and labelled as rayon in many jurisdictions. It is not raw bamboo fibre, but neither is it unrelated to bamboo.
The comparison that bamboo fabric is “not much better than plastic” overstates the case. Regenerated cellulose fibres such as viscose are plant-based and generally biodegradable under suitable conditions. Synthetic plastics like polyester are petroleum-based polymers and are not biodegradable in the same way. While viscose production can be chemically intensive, equating it with plastic is inaccurate.
Finally, the environmental impact of bamboo fabric depends heavily on how and where it is produced. Modern facilities in regulated regions may use solvent recovery systems that captures carbon disulfide vapours using enclosed ventilation systems. This helps to significantly reduce carbon disulfide emissions in the bamboo fabric production process and enables the factory to reuse the vapours in their next fabric production cycle.
A cleaner alternative to converting bamboo into fabric also exists, involving mechanically processing bamboo by crushing bamboo stalks then using natural enzymes (either cellulase or laccase) to retrieve fibres which are then spun into fabric. However, it is highly labor-intensive and costly, making it less common than the chemical production method using carbon disulfide.
In summary, the images correctly highlight that most bamboo fabric is chemically processed and that carbon disulfide poses real health and environmental risks. However, the broader claim that bamboo fabric is inherently not eco-friendly and essentially comparable to plastic is misleading and oversimplified.
