How long do biodegradable bags take to decompose?

How long it takes for biodegradable bags to decompose depends on a range of factors. If they’re placed in a microbe-rich environment to help it break down, biodegradable plastic bags can take anywhere from only a few months to a few years to fully break down. To compare, traditional plastic bags, on the other hand, take hundreds of years to fully decompose.

The issue is where biodegradable bags end up. Properly disposing biodegradable plastic bags and ensuring they end up in the right environment for decomposing is the only way to ensure they’re able to break down fully.
