Made from a blend of cornstarch and biopolymers, these bags are designed as a compostable alternative to conventional plastic packaging.

They are EN 13432 certified for industrial composting, meaning they meet the requirements of the recognised European standard for industrially compostable packaging.

The bags are also Carbon Neutral certified, reflecting our commitment to considering the environmental impact of our packaging.

These bags are certified for industrial composting under EN 13432.

They are designed for industrial composting rather than home composting. Check whether your local food-waste or commercial composting collection accepts EN 13432-certified compostable packaging before disposal.

Do not place them in conventional plastic recycling, as compostable plastics can contaminate plastic recycling streams.
