What is the difference between biodegradable and compostable bags?
Biodegradable and compostable bags are both types of eco-friendly bags that are designed to reduce environmental impact. However, there are some key differences between the two.
Biodegradable bags are designed to break down into natural materials, such as carbon dioxide, water, and biomass, when exposed to certain environmental conditions, such as heat, light, or moisture. However, there are no specific requirements for how long it takes for biodegradable bags to break down, and some biodegradable materials may still leave behind harmful microplastics.
Compostable bags, on the other hand, are specifically designed to break down quickly and completely in a composting environment, where they can be turned into nutrient-rich soil. Compostable bags are made from natural materials, such as plant fibers, and are certified to meet specific standards, such as the ASTM D6400 or EN 13432 standards, which ensure that they will break down within a certain timeframe and leave behind no harmful residue.
In summary, while both biodegradable and compostable bags are eco-friendly alternatives to traditional plastic bags, compostable bags are a more sustainable option because they are designed to turn into nutrient-rich soil, while biodegradable bags may still leave behind harmful microplastics.
