“…According to Kučerová [19], triticale is considered to be one of the best types of biomass for the production of bioethanol. Triticale can provide both starch and cellulose, and therefore it is important to assess its suitability as a raw material for biofuel production [21,22]. Triticale is particularly considered a promising source of biomass in Europe and is increasingly used in the production of bioethanol [23,24].…”

Energy use in agricultural production has been increasing faster than in many other sectors of the world economy. Owing to high energy consumption during the production of agricultural inputs, with mineral nitrogen fertilizers in particular, it is often questioned as to whether agricultural production is still energy efficient. The objective of this research was to evaluate the energy efficiency of different intensity systems for the production of semi-dwarf winter triticale cultivar ”Twingo”. Cultivar “Twingo” entered the Polish National List in 2012 as one of the best yielding. For this reason, it was used in this experiment to examine its response to basic agrotechnical factors. The field experiment was conducted in the Agricultural Experiment Station in Tomaszkowo in 2013–2015. Low-input, medium-input and high-input production systems were evaluated. The compared systems differed in nitrogen fertilization rates and the level of fungicide protection. The highest output/input ratio was noticed growing winter triticale in low-input production system. The most energy-consuming operation during winter triticale production in the compared systems was mineral fertilization. The high-input production system was significantly lower energy efficiency than the other systems (6.21, medium-input 5.95, low-input 8.19). The energy return on investment (EROI) ratio was low, but above 1, in all the analyzed technologies (low-input 1.30, medium-input 1.14, high-input 1.15). The energy value of the bioethanol produced was higher than the energy inputs into the production of raw material and its processing. The conversion of winter triticale grain to bioethanol proved that the EROI reached the most favorable value for the low-input production system.

“…SuperPro Designer® process simulator has been extensively used in modelling, evaluation and optimization of integrated biomass conversion process, especially for the first generation of biorefinery, such as bioethanol production [11,14,17,19,22,67,69], biodiesel production [72], food waste valorization [79], microalgae biorefinery [75], bio-jet fuel production [73,74], biogas production [77], hydrogen production from bio-methane [80]. Most of these processes are biochemical or fermentation processes.…”

“…Commercial and demonstration plants that turn wood scraps into ethanol have been either established or are being constructed by several chemical companies [5][6][7][8][9][10]. According to a number of recent studies, enzymatic hydrolysis of lignocellulosic biomass to ethanol and fuels has found to be generally economically feasible [11][12][13][14][15][16][17][18][19][20][21][22][23]. However, its operability at full capacity has not yet been attained due to a number of technical and economical hurdles [24].…”

In this study, the conceptual process flowsheet was developed and the economic feasibility of woody biomass conversion to biofuel as feedstock was analysed by considering several promising experimental processes for lignin depolymerization, such as hydrodeoxygenation and hydrogenolysis, along with lignocellulosic biomass fractionation processes. The engineering simulation process toward the commercial production of bio-gasoline from lignocellulosic biomass using SuperPro Designer® was modeled. The compatibility of the end products with the current gasoline specifications was evaluated and various blending options were investigated to meet the octane number and Reid vapor pressure requirement of the product. The economic potential of the simulated engineering process was then evaluated from an economic perspective. The operating costs and capital investment of three scenario using three different catalytic systems were estimated and discussed to assess of the potential of commercializing of woody biomass valorization process. The main potential market segments were identified, including the process by-products such as xylose and cellulose pulp. From the economic evaluation study, it was found that selling the biomass fractionation products alone does have a greater profit than valorization of lignin to produce bio-gasoline, with net present value of RMB 22,653,000 and RMB 177,000, respectively at the same return on investment if the plant is set up in Hong Kong. It was also found that catalysts play a pivotal role in determination of the profitability in the valorization process, not only because of the price of the catalyst, but also the product distributions obtained with various types of it. To obtain the same gross profit, the sale price of biogasoline has to be set higher with platinum catalysts than with ruthenium catalysts (nearly 10 folds). Thus, catalyst development and process improvement are crucial in the establishment of bio-based circular economy.

“…For bioethanol production, the effect of feedstocks and pre-treatment technologies on technoeconomics has been widely studied (Tao, et al, 2011) (Dickson, et al, 2018) (Mupondwa, et al, 2018). However, in the literature, there is lack of detailed cost analysis on immobilized cells and process types for bioethanol production.…”

Lignocellulosic ethanol production: Evaluation of new approaches, cell immobilization and reactor configurations

2019

The environmentally-friendly, economically-viable production of ethanol from cellulosic biomass remains a major contemporary challenge. Much work has been done on the disruption of cellulosic biomass structure, the production of enzymes for the conversion of cellulose and hemicellulose into simple sugars that can be fermented by bacteria or yeast, and the metabolic engineering of ethanol-producing microbes. The results of these studies have enabled the transition from laboratory to industrial scale of cellulosic ethanol production. Notably, however, current processes use free microbial cells in batch reactors. This review highlights the advantages of using immobilized and co-immobilized cells together with continuous bioreactor configurations. These developments have the potential to improve both the yield and the green credentials of cellulosic ethanol production in modern industrial settings.
