“…It was assumed that RBE would be produced chemically using the same equipment and, after minor modifications and additions, the same equipment would also be used for the production of RBE by applying the biotechnological method. Considering that butanol, in contrast to synthetic methanol, is obtained by biotechnological methods, its energy contribution was calculated according to the value of the life cycle energy efficiency indicator of butanol, 1.88, and the calorific value of butanol [14].…”

“…Thus, it is not possible to assert that the cellulosic residues will be cheaper than molasses. Van der Merwe et al [64] reported analyses of the energy efficiency and economics of biobutanol production using sugarcane molasses. Another important point to be analyzed related to the choice of substrate and its availability throughout the year.…”

Recent studies have shown that butanol is a potential gasoline replacement that can also be blended in significant quantities with conventional diesel fuel. However, biotechnological production of butanol has some challenges such as low butanol titer, high cost feedstocks and product inhibition. The present work reviewed the technical and economic feasibility of the main technologies available to produce biobutanol. The latest studies integrating continuous fermentation processes with efficient product recovery and the use of mathematical models as tools for process scale-up, optimization and control are presented.

“…For instance, pervaporation (a membrane-based separation technique) may reduce production costs, especially if combined with the fermenter as a hybrid process [6,71,72]. Recently, conceptual designs of alternative process routes for biobutanol production from sugarcane molasses were done using Aspen Plus and Aspen Icarus modeling tools [73]. Different fermentation modes (batch or fed-batch), bacterium strains (Clostridium acetobutylicum ATCC824 or PCSIR-10, Clostridium beijerinckii BA101) and downstream processing techniques (steam stripping distillation, liquid-liquid extraction or gas stripping with CO 2 ) were investigated.…”

European legislation concerning biofuels and their sustainability criteria are also briefly described. The need to develop methods to ensure more sustainable and efficient biofuel production processes is recommended. In addition, the assessment method to evaluate the sustainability of biofuels is considered and sustainability assessment of selected feedstocks for biobutanol production is performed. The benefits and potential of using lignocellulosic and waste materials as feedstocks in the biobutanol production process are also discussed. Sustainability assessment in this paper includes cultivation, harvest/collection and upstream processing (pretreatment) of feedstocks, comparing four main biomass sources: food crops, non-food crops, food industry by-product and wood-based biomass. It can be concluded that the highest sustainable potential in Finland is when biobutanol production is integrated into pulp & paper mills.
