Modified Biochemical Methane Potential (BMP) assays were used to assess biogas production potential of solid landfill samples. In landfill samples with visible soil content, moisture addition alone was generally as effective at stimulating biogas production as the addition of a comprehensive nutrient media. In a variety of samples from humid and semiarid landfills, addition of an aqueous nutrient media was the most effective stimulant for biogas production; however, moisture addition was almost as effective for most samples, suggesting that water addition would be the most cost-effective field approach. Onset of methanogenesis was slower in fresh refuse samples (even when inoculated with anaerobic digester sludge) than in landfill samples, indicating that the soil into which materials are landfilled is a major source of microorganisms. High volatile solids loading in fresh refuse and landfill assays retarded methanogenesis. A comparison of anaerobic and aerobic sample handling techniques showed no significant differences with regard to onset of methanogenesis and total gas production. The technique shows initial promise with regard to replication and reproducibility of results and could be a meaningful addition to landfill site evaluations where commercial gas recovery is anticipated. The BMP technique could also be adapted to assess anaerobic biodegradability of other solid waste materials for conventional anaerobic digestion applications. 9 refs., 6 figs., 2 tabs.
