“…The steam cost was $24/t in 2017, as estimated by scaling the 2001 price given in [48]. With a cash flow of 59% of utility cost and a return of investment of 23% at 7% interest rate, the payback time was 4.7 year at a discount rate of 21.4% [62]. Considering operation for 300 days per year, the bioethanol production cost via recovery is US$0.10/L ethanol.…”

Bioethanol is commonly recovered from fermentation broth via distillation because it is the most economical and reliable process for large-scale industrial operations. Because extraction is a highly energy-efficient process applicable to low-composition bio-product separation, high-performance solvents are necessary for efficient bioethanol recovery. 2-Methyl pentanol, a branched long-chain alcohol, which was used as the extraction solvent, and a deep eutectic solvent, choline chloride and ethylene glycol (1:2), was employed as an entrainer for product refinement. Thermodynamic models of vapor–liquid equilibrium (VLE) and liquid–liquid equilibrium (LLE) systems were derived using molecular simulations and experimental results to develop the bioethanol extraction and refinement processes. The heat duty of the designed process was reduced by a quarter compared to that of previous recovery processes. Graphic abstract

“…Nonetheless, the capacity of their plant model was fixed at 100,000 L/day, and only the chemical composition of the raw material was determined experimentally. Achinas et al (2019) analyzed the feasibility of a bioethanol plant from lignocellulosic feedstocks using a simulation software. Their process consists of multiple cycles of size reduction process to produce 99.7 wt.% ethanol.…”

Oil palm empty fruit bunch and trunk are classified as primary lignocellulosic residues from the palm oil industry. They are considered to be promising feedstocks for bioconversion into value-added products such as bioethanol. However,using these lignocellulosic materials to produce bioethanol remains a significant challenge for small and medium enterprises. Hence, techno-economic and sensitivity analyses of bioethanol plant simultaneously treating these materials were performed in this study. The information based on preliminary experimental data in batch operations wasemployed to develop a simulation of an industrial-scale semi-continuous production process. Calculations of mass balance, equipment sizes, and production cost estimation of the production plant of various capacities ranging from 10,000 L/day to 35,000 L/day were summarized. The result based on 20 years of operation indicated that the net present value of theplant of lower capacities was negative. However,thisvalue became positive when the plant operated with a higher capacity, 35,000 L/day.The highest ethanol yield, 294.84 LEtOH/tonfeedstock, was produced when the planttreated only an empty fruit bunch generating 8.94% internal rate of return and US$0.54 production cost per unit.Moreover, the higher oil palm trunk ratio in the feedstock, the lower ethanol yield contributing to the higher production cost per unit.©2020.

“…Instead, the ESBP can be valorised and used to produce value-added products because it is composed mainly of cellulose, hemicellulose, and pectin. Currently, ESBP has been used as raw material to produce biogas [10], hydrogen [11], ethanol [12], succinic acid [13], lactic acid [14], or enzymes [15].…”

Exhausted sugar beet pulp (ESBP), a by-product of the sugar industry, has been used as a substrate to produce lactic acid (LA). Due to the fact that ESBP contains a high percentage of pectin and hemicellulose, different pretreatments were studied to solubilize them and to facilitate the access to cellulose in the subsequent enzymatic hydrolysis. Several pretreatments were studied, specifically biological, oxidant with alkaline hydrogen peroxide (AHP), and thermochemical with acid (0.25, 0.5, or 1% w/v of H2SO4). Pretreated ESBP was enzymatically hydrolysed and fermented with the strain Lactiplantibacillus plantarum for LA production. The hydrolysis was carried out with the commercial enzymes Celluclast®, pectinase, and xylanase, for 48 h. After that, the hydrolysate was supplemented with yeast extract and calcium carbonate before the bacteria inoculation. Results showed that all the pretreatments caused a modification of the fibre composition of ESBP. In most cases, the cellulose content increased, rising from 25% to 68% when ESBP was pretreated thermochemically at 1% w/v H2SO4. The production of LA was enhanced when ESBP was pretreated thermochemically. However, it was reduced when biological and AHP pretreatments were applied. In conclusion, thermochemical pretreatment with 1% w/v H2SO4 had a positive impact on the production of LA, increasing its concentration from 27 g/L to 50 g/L.
