ISO 14855 – Ultimate Biodegradation – CO2 Evolution

ISO 14855 is a standard biodegradation test method that determines ultimate aerobic biodegradability and disintegration of plastic materials under controlled composting conditions.

To successfully compost a material or product, it must pass the phytotoxicity test to determine the quality of compost.This method predominantly measures ultimate aerobic biodegradation by the analysis of evolved carbon dioxide.

Ultimate aerobic biodegradation: Microorganisms fully consume a chemical compound or organic matter by in the presence of oxygen. Produces carbon dioxide, water and mineral salts.

Test requirements for ISO 14855 include standard testing for a minimum of 90 days and then the biodegradation results are determined after an analysis of evolved CO2.

A limitation seen with both ISO 14855 and ASTM D5338 is that these standard methods represent idealized composting facilities. To cover small-scale pilot composting, the ISO 16929 method is recommended in addition to the other standard test methods.

Compostable products have become more readily available; however, producers must perform compostability testing on their products in order to claim that their products are indeed compostable.

Compostable products have become more readily available; however, producers must perform the required testing on their products in order to make performance claims and achieve market acceptance.

Solid aerobic biodegradation and disintegration of plastic materials under controlled composting conditions is generally the accepted form of testing to make product performance claims.  However, it is highly recommended that customers check with their respective regulatory agency to determine which biodegradation test is required to make performance claims about their product’s biodegradability.  ASTM D5338, a more commonly requested test method, is performed at our laboratory.
