OECD 311 Biodegradability (Anaerobic Testing / ISO 11734)
OECD 311 biodegradability testing measures how a substance breaks down under anaerobic, oxygen-free conditions. This test helps determine how materials behave in environments such as anaerobic digesters, wastewater sludge, sediments, and landfills. Because oxygen is absent in these settings, anaerobic testing provides critical environmental information.
In simple terms, this test shows whether microorganisms can degrade a substance without oxygen. As a result, manufacturers can better understand environmental persistence and risk.
OECD 311 is technically equivalent to ISO 11734. Therefore, regulators widely accept the results for environmental fate evaluations.
Why OECD 311 Biodegradability Testing Matters
In many cases, substances enter anaerobic environments after disposal or wastewater treatment. For this reason, regulators expect data that reflects these conditions. OECD 311 biodegradability testing provides that information.
Additionally, this testing helps identify substances that may persist in anaerobic systems. Because of this, the results support environmental risk assessments and product stewardship programs.
How the OECD 311 Test Works
First, the test substance is added to an anaerobic microbial inoculum. Next, the system remains sealed to prevent oxygen exposure. Then, microorganisms begin to degrade the material if it is biodegradable.
During the study, the laboratory measures gas production, mainly methane and carbon dioxide. As a result, gas generation directly indicates biodegradation. Results are reported as a percentage of theoretical gas production over time.
Materials Commonly Evaluated
OECD 311 biodegradability testing applies to many materials, including:
-
Surfactants and detergents
-
Industrial and specialty chemicals
-
Polymers and additives
-
Wastewater-related substances
In addition, manufacturers often use this test alongside aerobic biodegradation studies to build a complete environmental profile.
Regulatory and Environmental Use
Overall, OECD 311 biodegradability data supports environmental risk assessments and regulatory reviews. For example, authorities may request anaerobic biodegradation results when evaluating chemical persistence.
To learn more, review OECD guidance on biodegradation testing published by international regulatory organizations.
