The test substances are exposed to an inoculum that is derived from compost from municipal solid waste. The test method for determining aerobic biodegradation of plastic materials in the marine environment by a defined microbial consortium or natural sea water inoculum (d6691). These standardised biodegradation tests can estimate the biodegradability of pure chemicals or individual components within materials

The assessments are conducted in settings designed to a certain extent, to mirror natural environments.
To support environmental responsibility and regulatory compliance, it is essential to rigorously test and verify biodegradability claims through standardized assessment methodologies.
1.2 this test method is designed to yield a percentage of conversion of carbon in the sample to carbon dioxide The rate of biodegradation is monitored as well. Astm d5338 determines the degree and rate of aerobic biodegradation of plastic materials upon exposure to a controlled composting environment This test is completed under laboratory conditions and at thermophilic temperatures (58ºc).
Key standards include astm d5338 for aerobic biodegradation and astm d6400 for compostability The testing process involves selecting plastic materials, obtaining activated sewage sludge, and measuring how they break down naturally.
