While often confused, compostable and biodegradable bags are not the same—and the difference matters, especially in foodservice operations aiming for sustainability.
Compostable bags are made from plant-based materials and designed to fully break down into non-toxic components—water, carbon dioxide, and biomass—within a specific timeframe under industrial composting conditions. These bags must meet strict standards like ASTM D6400 or EN 13432 to ensure they leave no harmful residue.
Biodegradable plastic bags, on the other hand, are often petroleum-based and engineered to break down more slowly. However, the term 'biodegradable' is loosely regulated, and these bags may only fragment into smaller pieces of plastic (microplastics) rather than decompose entirely.
For foodservice businesses, compostable bags provide a more transparent and reliable path toward sustainability. They align better with composting systems and offer verifiable environmental benefits, whereas biodegradable plastics can create confusion or contamination in waste streams.
Choosing the right type of eco-friendly bag helps businesses meet local regulations, reduce environmental impact, and demonstrate a real commitment to greener practices.
