Biobutanol has been emerging as a renewable replacement to overcome fossil fuel limit due to its attractive qualities. The waste resources utilization is an economically feasible and eco-friendly way to produce biobutanol. In this work, the potential of butanol fermentation with sweet potato residue (SPR) obtained from ethanol fermentation was evaluated. To assist sugar release for butanol production by Clostridia acetobutylicum, a pretreatment approach with dilute sulfuric acid was established via response surface methodology. The maximum butanol concentration of 3.77 g/L was obtained at the optimal conditions of pretreatment at 1% (v/v) dilute sulfuric acid, and 115℃ for 30 min. Detoxifying the hydrolysate with XAD-4 resin significantly enhanced butanol fermentation performance, while adding nutritional supplements had no significant influence. The stability of the fermentation process was verified by the 2 L-scale of fermentation, resulting in 7.96 g/L of butanol, 13.42 g/L h of Acetone-Butanol-Ethanol (ABE), and 0.34 g/g of ABE yield, respectively. This study demonstrates a bio-refinery strategy of conversion from waste biomass to energy, confirms the feasibility of utilizing the cost saving SPR as feedstock to produce butanol through fermentation, and provides a novel approach for minimization of environmental pollution.

“…Currently, oil, coal and gas still account for most of primary energy consumption [1]. However, due to the limited supply of fossil fuels, the increasing and fluctuating price of gasoline and environmental concerns brought by greenhouse gas emissions, there has been an increased interest in looking for green and sustainable energy [2].…”

A ternary nanocatalyst consisting of nickel cobalt oxide (NiCo 2 O 4 ), reduced graphene oxide (rGO), and platinum (Pt) was introduced as a promising catalyst for application in the sorbitol oxidation reaction (SOR) process for use in fuel cells. Other catalysts such as NiCo 2 O 4 , NiCo 2 O 4 -rGO, and NiCo 2 O 4 /Pt were prepared for comparison. The structure and morphology of the synthesized nanocatalysts were examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The efficiency of the as-synthesized materials was assessed by electrochemical tests of cyclic voltammetry (CV), linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS), and chronoamperometry (CA). The comparison of the SOR process for the synthesized nanocatalysts showed that NiCo 2 O 4 -rGO/Pt has the highest current density (57.2 mA cm À2 , 45.04 mA/mg) at a scan rate of 10 mV/s and the lowest peak potential (0.64 V) as well as the highest cyclic stability than other materials. The superior electrocatalytic performance is attributed to the synergistic effect of the components. Moreover, the charge transfer resistance of SOR for NiCo 2 O 4 -rGO/Pt catalyst is 702 Ω, lower than that for NiCo 2 O 4 /Pt (930 Ω). Thus, NiCo 2 O 4 -rGO/Pt constitutes an efficient and promising nanocatalyst for SOR.

“…The combination of the Delphi method and the Abacus of Régnier will be referred to as "Delphi-Régnier" in the following sections of this document. This combination is often used to quickly collect and summarize expert opinions [9,77], to facilitate debate and decision making [77,78], and foster creativity [26,79]. We will describe the conditions for implementing this study in the following subsections.…”

“…Some other studies have shown that between five and 11 experts ensures sufficient reliability, and that beyond 13 experts per group the average error of the group hardly decreases [79]. On the other hand, it can be noted that most of the recent studies combining the Delphi method and Régnier's abacus are based on a panel of about twenty experts [77,78,85,86]. Considering all the positions held during the three years preceding the time of the study, the panel of experts was finally composed of 24 experts distributed as follows: eight industrials, eight integrators, and eight academics.…”

Enhancing the Decision-Making Process through Industry 4.0 Technologies

In order to meet the increasingly complex expectations of customers, many companies must increase efficiency and agility. In this sense, Industry 4.0 technologies offer significant opportunities for improving both operational and decision-making processes. These developments make it possible to consider an increase in the level of operational systems and teams’ autonomy. However, the potential for strengthening the decision-making process by means of these new technologies remains unclear in the current literature. To fill this gap, a Delphi study using the Régnier Abacus technique was conducted with a representative panel of 24 experts. The novelty of this study was to identify and characterize the potential for enhancing the overall decision-making process with the main Industry 4.0 groups of technologies. Our results show that cloud computing appears as a backbone to enhance the entire decision-making process. However, certain technologies, such as IoT and simulation, have a strong potential for only specific steps within the decision-making process. This research also provides a first vision of the manager’s perspectives, expectations, and risks associated with implementing new modes of decision-making and cyber-autonomy supported by Industry 4.0 technologies.
