Degradable bags are made from plastic with other chemicals added (including heavy metals) that cause the plastic to break down and disintegrate over time when exposed to sunlight and heat. Like degradable bags, biodegradable are often still plastic bags that have microorganisms added to break down the plastic.
Compostable means that a product is capable of breaking down into natural elements in a compost environment. Because it’s broken down into its natural elements it causes no harm to the environment. The breakdown process usually takes about 90 days.
