Panama experiences sustained economic growth in the last 10 years. This results in some potential problems, such as the accumulation of wastewater biosolids (WWB) and they are disposed in landfills. For example, until 2014, approximately 75946 tons of WWB were deposited in the main Landfill in Panama. This situation generates great pressure on waste management and environmental management. In this sense, our research was based on the study of anaerobic digestivity of WWB using the Oxitop system, in order to estimate the kinetics and potential generation of biogas for its possible use. The characterization of WWB studied from various economic activities indicates their viability to use them, given their low concentrations of pollutants and their high content of organic matter. Digestivity tests indicate that the biogas production ranges were between 9.6 and 41.56 mL CH4 /g SV. These values are low compared to those reported in the literature and would not have the capacity to sustain an electricity generation activity; however, is possible to take advantage of theses biosolids if are mixed with other organic substrates to improve biogas production yields. |
