1.1 This test method covers determination of the degree and rate of anaerobic mineralization of carbon-based materials in a simulated landfill test environment. 1.2 This test method is also designed to produce mixtures of household waste and test materials after different degrees of decomposition under conditions that resemble landfill conditions. The test materials are mixed with pretreated household waste and exposed to a methanogenic inoculum derived from anaerobic digesters operating only on household or municipal waste. The anaerobic decomposition occurs under dry (more than 30% total solids) and static nonmixed conditions. 1.3 This test method can be used to assess the potential biogas production of test materials in landfill conditions. The mixtures obtained after this test method can be used to assess the environmental and health risks of materials that are degraded in a landfill.

This is a mirrored test method with D5526 which is under the jurisdiction of D20 (Plastics). There is industry interest in using this method for carbon-based materials that are not plastic, such as paper, fiber and other such materials. Per discussions with the chairpersons of both D20 and D34 as well as ASTM staff, it was decided that D34 should ballot the relevant standards within D34 that mirror the procedure but expand the types of materials used as test specimens. These new test methods may not be verbatim as they may have alterations that are relevant to differing types of carbon-based materials and use terminology as relevant for waste management and D34.
