OK Compost Industrial is an official certification label that tells you a product is compostable, but only in an industrial composting facility—not
at home.

That means the item needs special conditions—like high heat, controlled moisture, and sometimes shredding—to fully break down.

It’s issued by TÜV Austria, one of the main organizations that certifies compostable products in line with European standards (specifically EN 13432). This standard sets the rules for how fast and how completely a material must break down under industrial conditions.
