ASTM WK49654

    New Test Method for Determining Anaerobic Biodegradation of Materials in Landfill Environments by Bio-Chemical Methane Potential

    (What is a Work Item?)

    Developed by Subcommittee: D34.03 | Committee D34 | Contact Staff Manager


    1. Scope

    1.1 This test method covers the determination of the degree and rate of anaerobic biodegradation of carbon-based organic materials in municipal landfill conditions. The test materials are exposed to a methanogenic inoculum derived from a mixture of: organic fraction of decomposed municipal solid waste (MSW), anaerobic mixed municipal waste treatment digestate/sewage sludge, and landfill leachate. The anaerobic decomposition takes place under high-solids (more than 30% total solids) and static non-mixed conditions. 1.2 This test method is designed to yield a percentage of conversion of carbon in the sample to carbon in the gaseous form under conditions found in municipal landfills. 1.3 This test method is designed to be applicable to all carbon-based materials that are not inhibitory to the microorganisms present in municipal landfills. 1.4 Reports shall clearly state the percentage of net gaseous carbon generation for both the test and reference samples at the completion of the test. 1.5 The values given in SI units are to be regarded as the standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.7 Specific hazards are given in Section 8.


    anaerobic biodegradation; biodegradation; landfill


    Biodegradation of a material within a municipal landfill is an important phenomenon because it will affect the methane production, stabilization, toxicity, and overall long-term composition of the landfill site. This procedure has been developed to permit the determination of the rate and degree of anaerobic biodegradability of materials when placed in a municipal landfill. It is expected that this standard will be used by academia, laboratories, and landfill operators to measure and evaluate the biodegradation behavior of materials once disposed of within municipal landfills.

    The title and scope are in draft form and are under development within this ASTM Committee.
