| Summary: | "Biogas production has become a common practice for obtaining renewable energy, being implemented or expanded in many countries due to a large number of advantages. The organic material conversion to biogas may be improved and optimized by co-digestion that ensures a better supply of nutrients and oligo-minerals for the microbial population. Comparative assays were conducted on the co-digestion of selected waste under different mixing ratio to identify the optimal feedstock composition for a better biomethane production. Also, experiments investigated the influence of 5% microalgal biomass addition to the selected organic mixtures on biogas production and showed that the microalgal biomass slightly increased the biogas quantity and quality without causing any delay on the mass biodegradability. The anaerobic digestion of microalgae-additivated substrates may be used as optimization method to increase the economic profitability of the biogas plants. Further research is required to establish at which extent different percentages of microalgae may induce changes in the substrates biomethane potential. " |
