| Title | Insights into the synergistic effects of the anaerobic co-digestion of sludge and food waste through the modelization of semi-continuous experimental tests |
| Abstract | Food Waste (FW) anaerobic digestion has often experienced acidification problems in continuous systems. To investigate the reasons for this event, semi continuous experiments were carried out with variable operational conditions, including a set of anaerobic codigestion (AcoD) test conducted with FW and Waste Activated Sludge (WAS). The experiments were modelled with the Anaerobic Digestion Model n°1 (ADM1), whose outcomes were compared with microbial analysis, based on FISH and CARD FISH techniques. The synergistic effects of substrates merging were investigated, from both a mechanistic and biological point of view; in this light, a strategy capable to settle the acidification issue and exploit the FW methanation potential was proposed. |
