Vetted Performance Status

For BPI certification, this product was subjected to the following tests:

  • Biodegradation testing: measures the inherent ability of the organic carbon in a material to be consumed by microorganisms and shows that the material or item will not accumulate in nature.
  • Disintegration testing: measures whether the finished item physically breaks down and falls apart, demonstrate that the item will not create visual contamination in the compost, and indicates that the item is being successfully attacked by microorganisms (so that the carbon is readily available for biodegradation). It is based on the maximum thickness (or grammage for natural fiber) of the disintegration test determines the thickness/grammage of the product used for the disintegration test determines the certified maximum thickness/grammage for the item.
  • Compost Quality testing: this includes testing for metals/fluorine, Ash (VOC), and FTIR, as well as tests for Carcinogens, reproductive toxins, and mutagens (CRM). These tests and restrictions are designed to ensure that the compostable material or item does not have negative effects on compost quality.

Safety

Users must consider the following advice to ensure the safe and appropriate use of the product:

  • The bags are for food waste purposes. It is advised they are used within a year after purchase, and within 9 months after opening the package.
