The textile industry faces growing pressure to adopt sustainable materials, with bamboo fiber and recycled polyester (rPET) emerging as leading eco-friendly alternatives. Bamboo, a fast-growing, renewable resource, boasts natural antibacterial properties and biodegradability, while recycled polyester repurposes plastic waste, reducing reliance on virgin petroleum. However, their environmental impacts vary significantly.

Bamboo’s sustainability depends on processing methods—mechanical production (bamboo linen) is eco-friendly but rare, whereas chemical-intensive viscose processing raises pollution concerns. Recycled polyester, derived from PET bottles or textile waste, cuts carbon emissions by 23% compared to virgin polyester but sheds microplastics and remains non-biodegradable.

This article compares both materials across carbon footprint, water use, certifications, performance, and end-of-life impact to determine which aligns better with green textile standards. While bamboo excels in biodegradability and low CO₂ emissions, recycled polyester offers scalability and waste reduction. The choice hinges on prioritizing natural renewal versus circular economy principles.
