“…Therefore, the bioethanolic yield was 79% or 0.79ml bioethanol/ml fermented solution. The bioethanol content obtained in this study is very high compared to plant-based biomass such as agricultural and forest residue and other municipal solid waste, probably due to the very low content of lignin presence in wastepaper while most of the biomass contains high lignin content (Dubey et al 2012, Hossain &Jalil 2015, Hossain et al 2019b).…”

Enzymatic hydrolysis of waste biomass for bioethanol production is considered a traditional, inexpensive, and energy-effective approach decades ago. In the present study, waste office paper was pretreated with diluted sulfuric acid (H2SO4) and hydrolysed with one of the most available and cost-effective enzymes, cellulase from Trichoderma reesei, under submerged static condition. Wastepaper size was reduced to 2cm2, blended with water and dry wet-blended, and pretreated with diluted H2SO4. Among different concentrations (0.5M, 1.0M, 1.5M, 2.0M) of H2SO4, the maximum glucose content was obtained at 2.0M H2SO4 at 90 min reaction time, and glucose yield was 0.11g glucose/g wastepaper. The cut paper, wet-blended, and acid-treated wastepaper was hydrolysed with cellulase enzyme for 2, 4, and 5 consecutive days with 5mg, 10mg, 15mg, and 20mg enzyme loadings. The maximum glucose content was obtained, 9.75g/l after 5 days of enzymatic hydrolysis with 20mg enzyme loading and a glucose yield of a 0.5g glucose/g wastepaper. The wastepaper hydrolysate was further fermented for 6, 8, and 10 hours continuously with Saccharomyces cerevisiae (yeast), and at 10 hours of fermentation, the maximum glucose consumption was 0.18g by yeast. Later, HPLC analysis of the fermented medium presented a strong peak of bioethanol content at 16.12min. Further, the distillation of bioethanol by rotary evaporator presented 0.79ml bioethanol/fermented solution, which indicated the conversion efficiency of 79%.

“…Plant modeling simulated operating costs and the CO 2 and SO 2 emission will be determined to analyze if the overall bioethanol production from particular biomasses is or not economically favorable and environmentally benign. Previously, some researchers used HOMER and FermOpt software to perform this analysis [20,34]. In addition, commercially available process-simulation software packages (Aspen, SuperPro, etc.)…”

Due to the ever-growing pressure on our planet’s natural resources to supply energy, the production of bioethanol by fermentation of lignocellulosic biomass is increasingly important in courses related to engineering and energy. Moreover, recent changes in the teaching–learning paradigm make necessary the introduction of novel teaching tools where students are the protagonist of their education. In this context, the purpose of this study is to compare the results obtained after traditional lessons with those obtained after the implementation of various computer activities based on modeling and simulation of bioreactors to teach biorefinery concepts focused on bioethanol production. Berkeley Madonna was chosen as the digital simulation software package because it is user-friendly, fast, and easy to program. This software allowed students to gain experience writing models that let optimize fermentations in well-stirred bioreactors and others bioprocess of industrial interest. The students (those who participated in the modeling-simulation classes and those who participated in traditional ones) completed a questionnaire and a cognitive test at the end of the course. Students that participated in modeling-simulation classes got a better score than students that participated in traditional classes. Therefore, the study showed the improvement in the understanding of the biorefinery concepts and the students improved their grades. Finally, students’ perception about the proposed modeling-simulation learning was also analyzed and they rated the efficiency of this new learning methodology as satisfactory. There are very few studies providing information about educational experiences regarding the development of skills for the formulation, interpretation, simplification, and use of mathematical models based on mass balances and simple microbial kinetics in biochemical engineering courses. The experience described in this work can be used by professors to plan and conduct courses based on the modeling of biochemical engineering problems.

“…PAB peels, stalks, leaves, pseudostems, bunch-stems, rhizomes, and rotten fruits are categorized as agro-biomass [152]. Hossain et al [153] estimated that, for each tonne of PAB harvested, 4 tonnes of pseudostem are produced and decomposed in the field without any specific treatment, contributing to ecological degradation. Improper disposal of PBB results in harmful emissions of H 2 S, CO 2 , CH 4 , and toxic heavy metals, which can be extracted for functional application for bioenergy production or other industrial applications.…”

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.
