Determining the potential of both pure anaerobic sludge and anaerobic sludge mixed with Eucalyptus' ashes as fertilizers.

The generation of urban and industrial solid residues fit for recycling and reuse, calls for studies into the best ways to their reutilization. In this study, the potential use of both anaerobic pure sludge and anaerobic sludge mixed with Eucalyptus’ ashes as fertilizers was determined through mixing the of residues in the ratios of 30, 50 and 100 percent ashes in relation to the weight of dry sludge. Samples were collected and sent to the laboratory for analysis. The parameters that determine agronomical potential such as pH, humidity, volatile/total solids ratio, total organic carbon, sulphur, phosphorus, amonyacal nitrogen, total Kjeldahl nitrogen, potassium, magnesium and lime, were analysed. The vegetable biomass ashes from VERACEL Company contain accentuated alkalyne content. The mixing of anaerobic sludge and ashes is an advantageous process because the later contributed with potassium, lime and magnesium and the sludge provided nitrogen, and phosphorus, generating biosolids with the necessary nutrients for agricultural soil fertilization.
