• Biobased BDO can be synthetized from the chemical biobased succinic acid platform . However, Novamont (Italy) and Genomatica (US) have pioneered direct biobased BDO production methods, with the direct conversion of carbohydrates into BDO by fermentation . • Commercial fossil-based AA is mainly obtained by oxidation of cyclohexanol and cyclohexanone with nitric acid. To replace this rough process, many pathways have been developed for the synthesis of biobased AA , such as (i) a process based on 5hydroxymethylfurfural from different saccharides, (ii) the hydro-deoxygenation of glucaric acid by oxidizing D-glucose, or (iii) another way based on γ-valerolactone, synthetized by hydrogenation of levulinic acid, obtained from polysaccharides such as cellulose and hemicellulose. • The production of biobased TA is currently under strong investigations with great investments at academic and industrial levels, in the frame of the development of fully biobased PET. TA could be for instance obtained by oxidation of biobased p-xylene from different biomass . Several other pathways for the synthesis of TA from biomass can be based on terpenes, and are currently studied for industrial scaling up .
