Conclusion
Anaerobic Digestion of Biomass

Organic product treatment processes incorporating anaerobic digestion are booming, thanks in particular to the recent development of dry and multi-stage processes, which have now reached a high level of techno-logical maturity. Their scope of application is expanding, particularly in the context of the emergence of new value-added chains, geared towards the conservation and recovery of energy and nutrients, and the production of biosourced molecules. If methanization is to be widely and sustainably integrated into these value chains, overall process performance needs to be optimized. The development and optimization of pre-treatment stages (physico-chemical and biological) upstream of anaerobic digestion; coupling with emerging and/or complementary technologies (electro-fermentation, fermentative biohydrogen production), based on substantial advances in our knowledge of underlying mechanisms...
