“…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].…”

“…Recent studies on technoeconomic analyses of biomass to fuels have been reported extensively. These include the biomass to bioethanol [11,12,14,15,17,19,21,[67][68][69], synthetic fuels from biomass-derived levulinic acid [70,71], bio-jet fuel from biomass [16], biodiesel from biomass [20,[72][73][74], microalgae biorefinery [75], biomass gasification [76], biogas production [77] and biomass fractionation [78]. The aim of this study is to develop a process which converts the raw woody biomass into bio-blendstocks using catalytic depolymerization technology, which could be integrated as part of the conventional petroleum refinery processing, such as blending with reformate, or oxygenated chemicals to produce bio-gasoline.…”

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.

“…Enzyme cost contribution to bioethanol selling price has been shown to be as high as 48% [4] when corn stover is used as feedstock and around 13% on average [1]. Others have shown enzyme cost to have a considerable effect on operating costs varying around 16 [5] to 19% [6], when the feedstock is wheat straw and miscanthus, respectively.…”

“…Often, bioethanol process design studies incorporate enzyme cost and performance as static assumptions [6], specified targets [19] or uncertain variables [20]. There isn't a dynamic link in any of these examples or similar studies that could computationally propagate the effects of enzyme production optimization on the techno-economics of bioethanol production.…”

Biomass is the most versatile feedstock for renewable energy and chemical production. Biochemical techniques such as fermentation and biomethanation have been developed extensively for converting biomass into bioethanol, biogas, and high‐value platform chemicals. However, the techno‐economic feasibility of the various biochemical techniques for the production of a range of biofuels and chemicals has not been fully consolidated in a review. This paper reviews the techno‐economic studies of biochemical conversion of biomass in a comparative fashion between feedstocks, treatment methods, and product types. The review starts with an overview of various biomass treatment approaches and the need for pre‐treatment for processing second‐generation feedstocks. This is followed by a review of the main biochemical conversion processes, offering insights into process stages, product yields and quality, as well as commercialization prospects and challenges. The various techno‐economic aspects of biomass conversion via biochemical techniques, such as conversion efficiency, production capacity, minimum selling price, capital cost, unit production cost, and profitability metrics, are critically reviewed. It was found that bioethanol and biogas are the most commercially viable products from the biochemical processing of biomass. The production of other biofuels and chemicals such as biobutanol, biohydrogen, furfural, volatile fatty acids, succinate, levulinic acid, and sugar alcohols via biochemical techniques is still largely limited by low conversion, frail microbial strains, cost of enzymes, and separation, and refining challenges. Overcoming these technical bottlenecks, and addressing the issues of feedstock price and supply security, are crucial for enhancing the overall techno‐economic attractiveness of biochemical processes for fuels and chemical production from biomass resources. © 2023 Society of Industrial Chemistry and John Wiley & Sons Ltd.
