“…In 2013, these prices were reported to be between US$ 2.40/kg and US$ 2.60/kg, while those for bio‐based succinic acid were in the range of US$ 2.86/kg to US$ 3.00/kg, depending on the supplier and on the chemical specification . The main current production route is through oxidation of n‐butane to produce maleic anhydride, which is then hydrogenated and hydrolyzed . Succinic acid is also a common metabolite of living organisms, since its ionic form (succinate) is one of the intermediates of the tricarboxylic acid cycle and the glyoxylate shunt.…”

Bio‐based succinic acid is a potential building block for the production of renewable chemicals and polymers. The use of hemicellulosic hydrolyzate from sugarcane bagasse allows production of succinic acid without competing with food chains and increasing the biomass ‐aggregated value. This work assesses the economic impacts of integrating the production of ‐succinic acid on an optimized sugarcane biorefinery with the production of first‐generation ethanol and electricity. Process simulation was performed to obtain mass and energy balances of the entire process, from bagasse pre‐treatment to pentose fermentation and succinic acid recovery, using several pieces of technical information and data taken from the scientific literature. After ‐assessing the impacts of key economic variables through risk analysis, the obtained results were benchmarked against those of an optimized ethanol distillery. Calculated succinic acid production cost was US$ 2.32/kg, comparable to costs related to less expensive sugar sources. The integrated succinic acid biorefinery presented a slightly lower internal rate of return (IRR) compared to an ‐ethanol distillery. However, even when considering uncertainties, succinic acid production has a strong probability (84.6%) of achieving an IRR higher than 12%. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd

“…Hydrolysates of bladderpod press cakes have been investigated for microbial fermentations for producing succinic acid [116] and butanol [118]. Production of itaconic and succinic acids has been reported by fermentation of hydrolysates of jatropha press cakes [119]. Hydrolysates of jatropha hulls were suitable for producing 2,3-butanediol [120].…”

Biodiesel production currently follows a first-generation model using edible oils as raw materials. Such a production model is unsustainable, considering that it is limited by the high cost of edible oils, competes with the food sector, and is linked to deforestation and other environmental threats. Changing the raw material base to non-edible oils provides an opportunity to increase the sustainability of the biodiesel industry and to avoid conflicts with food production. Processing non-edible oilseeds for extracting the oil to be used for producing biodiesel generates large amounts of residues, such as de-oiled cakes, seed husks, and fruit shells and pods as well as plant stems and leaves resulting from pruning and other agronomy practices. Most of those residues are currently disposed of by burning or used in a suboptimal way. Bioconversion following the sugar platform route, anaerobic digestion, or enzyme production provides means for upgrading them to advanced biofuels and high-added value products. Bioconversion of plant biomass, including oilseed residues, requires pretreatment to enhance their susceptibility to enzymes and microorganisms. This review provides an outlook on bioconversion approaches applicable to different residues of oilseed-bearing plant species. Recent reports on the pretreatment of non-edible oilseed residues for enhancing their bioconversion through either the sugar platform route or anaerobic digestion are critically discussed. This review is based on an exhaustive Web of Science search performed in January–May 2023.
