What Is ASTM D5526 Plastic Anaerobic Accelerated Landfill Biodegradation?
The ASTM D5526-18 standard test method evaluates the biodegradation behavior of plastic materials under simulated landfill conditions. In this test, regulated mixtures of plastics and household waste are created, and their breakdown is observed under anaerobic, landfill-like conditions.
The technique aids in evaluating the environmental and human health effects of landfill-degraded plastics. Throughout a landfill’s active life, accelerated biodegradation helps recover landfill gas, reduce long-term aftercare, and reduce waste volume.

Our ASTM D5526 Testing Procedure
Reactor Setup
Waste and plastic samples are loaded into sealed reactors and placed in incubators at 35 ± 2°C for stabilization.
1Incubation
Reactors are kept under dark conditions for extended incubation.
2Pressure Monitoring
Internal pressure is monitored and measured when it reaches 700 mbar.
3Gas Release & Continuation
Gas is released to atmospheric pressure, and testing continues until gas production stops or reference degradation exceeds 70%.

ASTM D5526 Plastic Anaerobic Accelerated Landfill Biodegradation FAQs
ASTM D5526 determines the degree and rate of anaerobic biodegradation of plastic materials under accelerated landfill conditions. The test evaluates the conversion of carbon in the plastic into gaseous carbon, primarily through anaerobic biological activity.
The method was developed for plastic materials exposed to biologically active landfill-like conditions. Test specimens are mixed with pretreated household waste and exposed to a methanogenic inoculum under dry, static, non-mixed conditions.
Biodegradation is evaluated by measuring the conversion of carbon from the plastic into gaseous carbon, including carbon dioxide and methane. Results are compared with appropriate reference materials to determine the extent of anaerobic biodegradation under the specified laboratory conditions.
ASTM D5526 was designed to create a standardized, accelerated laboratory environment resembling a biologically active landfill, but it does not represent every type of landfill. In particular, results may not reflect conditions in biologically inactive landfills.
Results should not be used to make an unqualified “biodegradable” claim. The original method states that performance claims should be limited to the numerical results obtained under the specified test conditions and should not be extrapolated beyond the actual test duration.
