Cellulose acetate degrades in between 18 months and 10 years depending on environmental conditions. A plastic bag can be there in 100 years. > While it was initially believed that CA was virtually non-biodegradable, it has been shown that after initial partial deacetylization the polymer's cellulose backbone is readily biodegraded by cellulase enzymes. In biologically highly active soil, CA fibers are completely destroyed after 4–9 months.
