Abstract
EXPRESS will develop an integrated biorefinery to recover high-value compounds and hydrogen from fishery wastes and bioproducts, which are a potential source of hydrolysed proteins, fatty acids, enzymes. In the biorefinery scheme of EXPRESS, soft parts, such as fish viscera and filleting residues, as well as the organic fraction of mollusc wastes will be processed by (photo)fermentation approaches and enzymatic hydrolysis to obtain protein hydrolysates, bioactive peptides, omega-3 rich oils and medium chain fatty acids. The effluent will be sent to a separation section or to other processes to l produce hydrogen and poly-β-hydroxybutyrate. The separation section of EXPRESS will exploit low-temperature processes to purify streams from the upstream processes. Dialysis and electrodialysis will be also considered. The lean streams of the biorefinery will be processed in the energy carrier generation section, where fermentation will be combined with microbial electrolysis to obtain hydrogen. A final process of anaerobic digestion will exploit the remaining energy content of the biorefinery residues. Finally, an alternative biological photofermentation approach will be developed for biogas upgrading by H2S removal and CO2 exploitation by autotrophic metabolism.
