These eco-friendly bags fully biodegrade and compost, significantly reducing waste in landfills and improving environmental sustainability.

Tiny Box Company’s compostable bags are 100% compostable when disposed of correctly. Some are suitable for home compost bins alongside food waste and garden cuttings, while others require industrial composting - check each product’s description for details.

Although compostable bags might break down in landfill, we strongly advise using the recommended composting methods for maximum environmental benefit. Composting times vary depending on material type and conditions.

Store your compostable bags in a cool, dry place, away from moisture, direct sunlight, and strong odours to maintain their quality.
