Shanmugam, P and Horan, NJ (2009) Simple and rapid methods to evaluate methane potential and biomass yield for a range of mixed solid wastes. Bioresource Technology, 100 (1). pp. 471-474. ISSN 0960-8524
Abstract
This paper describes rapid techniques to evaluate the methane potential and biomass yield of solid wastes. A number of solid wastes were mixed to provide a range of C:N ratios. Empirical formulae were calculated for each waste based on the results of chemical analysis and these formulae were used to estimate the COD equivalent and stoichiometric methane potential (SMP). The actual COD and biochemical methane potential (BMP) were determined experimentally for each waste and for both parameters there was a good agreement between the empirical and experimental values. The potential of adenosine triphosphate (ATP) to act as an indicator of biomass yield (mg VSS mg1 COD removed) was determined during the anaerobic digestion process. The biomass yield determined from ATP analysis was in the range 0.01–0.25 mg VSS mg1 COD removed which corroborated well with previously reported studies. Empirical formula based SMP together with ATP measurement were shown to provide rapid methods to replace or augment the traditional BMP and VSS measurements and are useful for evaluating the bioenergy and biomass potential of solid wastes for anaerobic digestion.
