Anaerobic Biodegradation of Plastic Materials ASTM D5511

Anaerobic Biodegradation of Plastic Materials ASTM D5511

ASTM D5511 is used to determine Anaerobic Biodegradation of Plastic Materials Under High-Solids Anaerobic-Digestion Conditions. This test procedure is helpful for different types of plastic materials.


    ASTM D5511 determines the rate and degree of anaerobic biodegradation of plastic materials in high-solids anaerobic conditions. The test samples are exposed to a methanogenic inoculum (methane-evolving microorganisms) obtained from anaerobic digesters working on pretreated waste. The ASTM D5511 test procedure is useful for different types of plastic materials. 

    Test Procedure:

    Anaerobic Biodegradation of Plastic Materials test by ASTM D5511 is performed by using a concentrated anaerobic inoculum. The test material is exposed to an anaerobic static batch fermentation, and the total carbon in the gas (carbon dioxide and methane) evolved is measured as a function of time. The percentage of biodegradability is achieved by calculating the percentage of sample carbon converted to methane and carbon dioxide). 

    Sample size:

    The test samples can be in the form of pellets, films, powder, articles, or dog bone-shaped samples as specified by ASTM D618 guidelines. The test samples are analyzed for their carbon content as per ASTM D4129 guidelines.
