ASTM E1963 Biodegradation Rate in Municipal Waste
The ASTM E1963 test method is a critical tool used to assess the biodegradability of materials intended for disposal in municipal solid waste (MSW) landfills. This service evaluates how quickly organic compounds within products decompose under controlled conditions that simulate landfill environments. Understanding this rate helps stakeholders ensure compliance with environmental regulations and promotes sustainable waste management practices.
The test measures the mass loss or carbon dioxide production from a specified amount of material over time, typically 12 weeks. This duration aligns closely with the average decomposition period in modern landfills. By quantifying biodegradation rates under these conditions, laboratories can provide valuable insights into product performance and environmental impact.
For this test, samples are prepared by cutting them to standard dimensions and weights as per ASTM E1963 guidelines. Samples are then incubated in a controlled environment designed to mimic landfill conditions—specifically, a temperature of 58°C ± 1°C and humidity levels maintained at 80% relative humidity.
The test involves placing the prepared samples into biodegradability bags or containers, which are sealed to prevent external contamination. These containers are then placed in an incubator set to the specified conditions for a defined period of time (usually up to 12 weeks). During this phase, the weight loss of each sample is recorded periodically.
Following completion of the test cycle, samples are removed from the incubation chamber and dried under standardized conditions. The final step involves weighing the samples again to determine their mass loss during the test period. Additionally, carbon dioxide (CO2) production can be measured using gas chromatography for more comprehensive analysis.
