What are biodegradable fabrics?

Biodegradable fabrics are textiles made from natural or regenerated fibers that can be broken down by microorganisms and returned to the earth at the end of their useful life. Common examples include organic cotton, hemp, linen, merino wool, silk, and regenerated cellulose fibers like Tencel (lyocell) and modal. These materials decompose naturally under the right conditions, unlike synthetic fabrics such as polyester and nylon, which can persist in the environment for hundreds of years.

The rate and completeness of biodegradation depend on several factors, including the fiber composition, any chemical treatments or dyes applied during manufacturing, and the conditions of the disposal environment. A garment made from 100% untreated organic cotton may fully decompose in a matter of months in a composting environment, while blended fabrics or those treated with synthetic finishes will take significantly longer and may leave behind residues.

ONDU focuses on curating products made primarily from biodegradable natural fibers because we believe the end-of-life impact of clothing matters as much as how it is made. Brands on our platform like Organic Basics, Mate the Label, and Boody prioritize materials that will not burden landfills or pollute ecosystems long after they have been worn and loved.
