“…Lignocellulosic plants such as PAB waste are biomass with a potential renewable energy source for the future, which will lessen the use of non-renewable fuels. Safarian et al [76] studied pyrolysis syngas with many other different kinds of agricultural biomass for bioethanol production and found that carbon monoxide (CO) and H 2 in the syngas are the core paramount gases. High ethanol yield production is feasible to modify CO and H 2 in pyrolytic syngas output.…”

Globally, fossil fuel dependence has created several environmental challenges and climate change. Hence, creating other alternative renewable and ecologically friendly bio-energy sources is necessary. Lignocellulosic biomass has gained significant attention recently as a renewable material for biofuel production. The large amounts of plantain and banana plant parts wasted after harvesting, as well as the peels generated daily by the fruit market and industries, demonstrate the potential of bioenergy resources. This review briefly assesses plantain and banana plant biomass (PBB) generated in the developing, developed, and underdeveloped countries, the consumable parts, and feasible products yield. It emphasized the advantages and disadvantages of the commonly adopted treatment technologies of composting, incineration, and landfilling. Further, the utilization of PBB as catalysts in biodiesel synthesis was briefly highlighted. To optimize recovery of biofuel, different integration routes of pyrolysis, anaerobic digestion, fermentation, hydrothermal carbonization, hydrothermal liquefaction, and hydrothermal gasification for the valorization of the PBB were proposed. The complex compounds present in the PBB (hemicellulose, cellulose, and lignin) can be converted into valuable bio-products such as methane gas and bio-ethanol for bioenergy, and nutrients to promote bioactive ingredients. The investigation of the viability and innovation potential of the integrated routes' technology is necessary to improve the circular bio-economy and the recovery of biofuels from biomass waste, particularly PBB.

Biomass pyrolysis is considered as a thermochemical conversion system that is performed under oxygen-depleted conditions. A large body of literature exists in which thermodynamic equilibrium (TE) and kinetic approaches have been applied to predict pyrolysis products. However, the reliability, accuracy and predictive power of both modeling approaches is an area of concern. To address these concerns, in this paper, two new simulation models based on the TE and kinetic approaches are developed using Aspen Plus, to analyze the performance of each approach. Subsequently, the results of two models are compared with modeling and experimental results available in the literature. The comparison shows that, on the one hand, the performance of the TE approach is not satisfactory and cannot be used as an effective way for pyrolysis modeling. On the other hand, the results generated by the new model based on the kinetic approach suggests that this approach is suitable for modeling biomass pyrolysis processes. Calculation of the root mean square error (RMS), to quantify the deviation of the model results from the experiment results, confirms that this kinetic model presents superior agreement with experimental data in comparison with other kinetic models in the literature. The acquired RMS for the developed kinetic method in this paper varies within the span of 1.2 to 3.2 depending on temperature (400–600 °C) and various feedstocks (pine spruce sawdust, bagasse, wood bark, beech wood and paddy straw).

“…Chniti et al [27] obtained a higher ethanol yield of 37.2 g/L by supplementing date syrup with ammonium chloride (1.0 g/L). Shafaghat et al [30] reported that using NH 4 Cl with an initial concentration of 1.5 g/L produced 14.1 g/L of ethanol from molasses (35 g/L). These values of bioethanol concentration are lower than those obtained in the current work, showing the efficiency of the "Khodhari" dates as a promising feedstock for bioethanol production by S. cerevisiae, especially in Saudi Arabia.…”

Given crude oil prices and their environmental impacts, the use of sustainable renewable alternative energies such as biofuels is rapidly progressing in numerous countries. Among biofuels, bioethanol is a renewable and clean fuel that can be obtained from the fermentation of several raw agricultural materials, including date fruit. However, the low product yield, mainly due to the low-grade nutrient content, limits its use as a promising alternative biofuel. This current study investigated bioethanol production from date by-products in Saudi Arabia and examined the impact of calcium and nitrogen sources added at different concentrations (0 to 1 g/L) on the productivity and ethanol concentration using Saccharomyces cerevisiae. Yeast extracts and ammonium chloride (NH4Cl) were tested as nitrogen sources for bioethanol fermentation from date juice. Calcium chloride (CaCl2) and calcium carbonate (CaCO3) were evaluated as calcium sources for the same purpose mentioned above. The results showed that both calcium and nitrogen sources improved ethanol production efficiencies. The addition of calcium sources such as CaCl2 at 0.4 g/L resulted in maximum ethanol concentration (41.5 ± 0.85 g/L) and the highest productivity of 0.511 g/L/h. Thus, an increase of 31.3% compared to the control sample was acquired. Ammonium chloride was found to be the best nitrogen supplement among them. Indeed, supplementing the fermentation medium with 1 g/L NH4Cl gave an optimal ethanol concentration and productivity, reaching more than 65 g/L and 0.83 g/L/h, respectively. This is an increase of 106.6%. The functional group of ethanol (C2H5OH) for all the elaborated samples was confirmed by Fourier-transform infrared spectroscopy (FTIR) and NMR analyses. Moreover, the results confirmed the high quality and purity of the bioethanol products. Thus, the “Khodhari” date variety of low market value is a privileged substrate for industrial bioethanol production. For this reason, a proposed flow diagram of a designed plant for bioethanol industrialization is provided and detailed.
