Co-substrate analysis for biogas production enhancement in an anaerobic digestion plant of Argentina

Abstract

Anaerobic co-digestion is a feasible option to overcome the drawbacks of mono-digestion and to improve the economic viability of anaerobic digestion plants due to higher methane production. It offer several benefits over digestion of separate materials, such as increased cost-efficiency (one plant several waster), increased degradation of the treated materials due to synergistic effects, improve optimal moisture and nutrient content, and also dilution of inhibitive compounds. The TFM was focused on Sudoeste Plant, a WWTP (wastewater treatment plant) from Buenos Aires where the sludge treatment plant is currently being built. The co-substrate selected was the biowaste from Central Market due to its proximity to the plant
