“…Techno-economic analysis (TEA) is used to calculate the feasibility of xylitol production from EFB. The key factors that affecting the economic feasibility of the biomass conversions were the plant capacity, feedstock cost, product yield, and process configuration [10]. Economic feasibility analysis starts from the estimation of the total capital investment (TCI) using the Peters and Timmerhaus factors seen in Table 1 [11].…”

Empty fruit bunch (EFB), one of the wastes from palm oil production, can be utilized into fuels and chemicals. The aim of this paper is to find the optimum capacity to produce xylitol from EFB. The optimum capacity was found by simultaneously considering its profitability, hazard potential and environmental performances. The process was developed and simulated using Aspen Plus to analyze its technical challenges and economic performances, covering net present values, internal rate of returns and payback period. On the other hand, hazard identification and ranking (HIRA) was used to evaluate its safety performances, while Simapro V.8.5.2 was used to assess the environmental impact via a life cycle assessment (LCA). The results show that the high consumption of steam in chemical hydrogenation causes the main contribution of Global warming potential (GWP) by 62%. This acid pre-treatment is also considered the most toxic part of the process while the hydrogenation of xylitol is the most hazardous part based on fire and explosion perspectives. Then, multi-objective optimization using Genetic Algorithm (GA) was performed in Matlab to find the optimum capacity. The methodology and result of this work lay the foundation of future works in utilizing.

“…First, is the low yield obtained per kg of biomass treated, approximately by 1kg of biomass processed, are produced 100 g of ethanol would be produced. At this point is important to highlight other problem; the water present during the enzymatic saccharification and fermentation, makes the downstream process expensive and energy-intensive, therefore to develop a sustainable biorefining process, the ethanol production must be coupled with the production of high value-added molecules such as xylitol, furfural, organic acids, 5-HMF, and lignin valorization as reported by different authors [27,[34][35][36][37].…”

Currently, the continuous depletion of non-renewable resources of fuels and chemicals has promoted the research and development of different alternatives for the replacement of fossil resources as the feedstock of fuels and chemicals. At present, one of the most important biofuels in the current economy, is bioethanol, contributing to 65% of the total biofuels production. The production of bioethanol is an attractive alternative because it would be produced using indigenous and native raw material, therefore, the socioeconomic impact mainly in developing countries would be measured by the economic incomes and increase the quality of life of small and middle farmers. The first-generation ethanol production from sugarcane, corn, or beet sugar is broadly implemented at an industrial scale. However, the second-generation ethanol (2GE) is currently still in development stages, looking for different alternatives according to each region under study. The 2GE is also subject of diverse opinions about its economic viability and its real impact on the environment, especially due to the CO2 footprint. Consequently, this chapter has presented an overview of 2GE production, the possibilities of co-production of molecules of high value-added, and their economic and environmental assessment, including CO2 release, water consumption, solid residues disposal, and economic analysis to determine the best bioethanol based biorefinery configuration.

Many studies are carried out in different countries to find alternatives of hydrocarbon-based fuels,1 which include hydro, wind, biofuels, solar, and geothermal energy. One of the major biofuels isbioethanol, a clear, colorless liquid, biodegradable, and lowin toxicity, and can be considered as a high-octane fuel oroctane enhancer in domestic petrols. The pre-treatment process for oil palm empty fruit bunches (OPEFB) or empty fruit bunches (EFB)for produce bioethanol require convert the complex lignocellulose structures into enzymatically digestible forms and easy handling for use. The pre-treatment can to be divided into physical, chemical, biological and physico-chemical tre-treatment. Various studies on the subject are presented below either a single treatment or combination of several. Nevertheless, the most important problem with bioethanol downstream processing is the dewatering step due to azeotropic formation during distillation of ethanol-water mixtures. Currently, different methods like direct contact membrane distillation (MDBR), extractive batch distillation, pervaporation, adsorption, molecular sieve and pressure Swing Adsorption (PSA) are used for bioethanol dehydration with regard to the absolute ethanol production. Also, mass and energy integration processes are also reviewed.
