Combined with our innovative business services, they enhance performance and help everyone have confidence in the things they buy and use – from the toy in a child’s hand to the aircraft overhead. By understanding commercial needs and consumer priorities, we touch every part of everyday life – helping our world work better.” – ASTM International

Bioplastics Certifications

• Test method that determines the amount (%) of new carbon (biomass carbon) compared to old carbon (fossil carbon)
• Based on total carbon content of the material and not total mass of the material
• Contemporary biomass has 100% radiocarbon and is absent (0%) of fossil fuels. ASTM D6866 uses this difference to determine the amount of biomass carbon vs. fossil carbon.

• Specification for compostable plastics
• For plastic films and solid plastic products
• Specifies three criteria
  1. Disintegration
     • Less than 10% of test material remains on 2mm sieve
     • Controlled compost conditions at thermophilic conditions (135°F / 58°C) as defined in ASTM D5338 & ISO 16929 test methods
     • Time: 12 weeks or less (84 days)
  2. Mineralization / Inherent Biodegradation
     • 90% Conversion to carbon dioxide, water & biomass via microbial assimilation
     • ASTM D5338 – defines test method used
     • Time: 180 days or less (the same rate as natural materials – leaves, paper, grass, and food scraps)
  3. Safety
     • No impacts on plant growth, using OECD Guide 208
     • Regulated (heavy) metals less than 50% of EPA prescribed threshold

• Specification for compostable plastic used on paper and other compostable substrates
• For packaging and food service items, made of plastic coated paper, board, and other fibers.

• Provides an independent certification program for products that meet all requirements of the ASTM D6400 and ASTM D6868 (if applicable) standards
• Uses independently approved labs and reviewers
• Not based only upon manufacturer’s claims
• Recognized by municipalities and composters across the US and Canada
