The development of innovative technologies is desirable to accomplish the greenhouse gas reduction targets. The present work is aimed at combining CO2 capture and its use in conjunction with biomass conversion. In constant association with lab-scale and pilot trials, the project focused on demonstration activities directly on the operative sites of industrial partners. CO2 was captured from the local sludge incinerator flue gas and recovered as a concentrated stream. A Two-Phase Anaerobic Digestion (TPAD) process...
