They meet the stringent requirements of BPI (Biodegradable Products Institute) and adhere to the ASTM D6400 standard for commercial compostability. This means they will break down into natural elements (water, CO2, biomass) in a commercial composting facility within approximately 90-180 days.
Made primarily from plant-based materials like corn starch and PLA, these bags help reduce reliance on fossil fuels and combat plastic pollution. Choosing ORIZON compostable bags is a step towards a more sustainable future.
