Though biodegradable and compostable packaging is infinitely better for the environment than your degradable bags and boxes, there are a few differences between them. Biodegradable packaging contains microorganisms that help break down plastics into the Earth and turn it into carbon dioxide, water vapor, and organic material. They break down anywhere between a few months to years -- a far better option than degradable plastic’s 1000-year breakdown time. The foundation of compostable packaging is natural plant starch that breaks down through microbial activity. The process creates compost, which breaks down easier. Compostable material is the superior option for packaging; biodegradable materials are still significantly better for stores to aid in their mission to reduce the amount of waste they produce.
