Compostability

As consumers and industries alike become increasingly concerned about the environment, the demand for compostability/biodegradability testing is also on the rise. As part of NSF's mission to protect public health and the environment, NSF provides high-quality laboratory testing to demonstrate compliance with the following biodegradability standards:

  • ASTM D6400 - Standard Specification for Compostable Plastics
  • ASTM D6868 - Standard Specification for Biodegradable Plastics Used as Coatings on Paper and Other Compostable Substrates
  • EN 13432 - Requirements for Packaging Recoverable Through Composting and Biodegradation - Test Scheme and Evaluation Criteria for the Final Acceptance of Packaging

Meeting these compostability standards verifies that your plastic products will biodegrade swiftly and safely during municipal or commercial composting.

There are three main types of testing required by these standards:

  1. Biodegradation - Test runs anywhere between 9 and 24 weeks; determined by measuring the amount of carbon dioxide produced from degrading plastic
  2. Disintegration - A 12-week test similar to the biodegradation test without the gas measurement
  3. Eco-toxicity - Roughly a 3-week test; determined by measuring plant growth and germination from soils mixed with varying concentrations of compost and product

Accreditations

NSF International is approved by the Biodegradable Products Institute (BPI) to conduct testing and demonstrate compliance with ASTM D6400, ASTM D6868, and EN 13432 for compostability. See the NSF listing on the BPI website or visit www.nsf.org/info/bpi_compostable.

In addition, NSF has a 60-plus year history of testing and laboratory accreditations including ISO/IEC 17025, International Accreditation Service, Standards Council of Canada (SCC), Occupational Safety and Health Administration (OSHA), and American Society of Sanitary Engineering. NSF is fully equipped to offer you the finest compliance services available today.

Known for its dedicated customer service and state-of-the-art test laboratories, NSF can offer you timely, cost-effective testing to determine the compostable nature of your products.
