Is bamboo fabric actually sustainable or is it greenwashing?

Most fabric sold as bamboo is actually bamboo viscose or bamboo rayon, which is a chemically processed regenerated cellulose fiber. The manufacturing process dissolves bamboo pulp using carbon disulfide, a toxic solvent linked to neurological damage in factory workers. By the time the fiber is produced, virtually none of the original bamboo's natural antimicrobial or structural properties remain.

The FTC has taken action against companies for marketing bamboo viscose as natural bamboo fabric, calling it deceptive advertising. The finished fiber is chemically identical to viscose made from any other wood source. The bamboo plant itself grows quickly without pesticides, but the processing negates much of that environmental benefit through toxic chemical use and wastewater generation.

Truly sustainable alternatives include Tencel (lyocell), which uses a closed-loop solvent system that recovers and reuses over 99% of its solvent. Organic cotton and linen are also straightforward choices with minimal processing chemicals. ONDU favors Tencel over bamboo viscose because it delivers similar softness and performance through a genuinely cleaner manufacturing process.
