Products that actually are eco-responsible have been certified by an official third party organization and will have a certification label displayed on their box. Some of the most recognized third party testers are:
• The Compost Manufacturing Alliance
• ASTM International
• The Biodegradable products Institute (BPI)
• TüV Austria
• Din Certco
• European Standard (EN)
Only products that have third party testing can claim to be biodegradable or compostable.
