Abstract Bioethanol production from lignocellulosic biomass has become an economical and environmentally friendly substitute to current petroleum-based fuels. This is due its ability decrease carbon dioxide emissions make use of plentiful natural resources. Current advances in this area concentrate on improving the effectiveness expandability conversion procedures by using inventive pretreatment approaches, enhanced enzyme compositions, refined fermentation technologies. Consolidated bioprocessing (CBP) utilizing genetically modified microbes have expedited decomposition intricate complexes overall productivity. Furthermore, process intensification developments, such as adoption hybrid reactors continuous systems, considerably decreased expenses energy usage. Nevertheless, there are still obstacles overcome, including raw materials inconsistency, demand for efficient recovery purifying techniques, financial viability extensive processes. study examines latest developments bioethanol biomass. It focuses ecological technical advancements, main that need be overcome exploit promise a biofuel fully. review primarily focused outcomes documented last five years 2019 2024. The first segment work second-generation process, which includes: properties composition biomass, pretreatment, enzymatic saccharification, fermentation. subsequent portion paper techno-economic analysis, prospective technology outlook. finishes discussing findings research fields haven't been investigated yet, besides faced manufacturing methods.

Efficient Bioethanol Production from Spent Coffee Grounds Using Liquid Hot Water Pretreatment without Detoxification

Fermentation, Год журнала: 2024, Номер 10(8), С. 436 - 436

Опубликована: Авг. 21, 2024

Coffee beans, a popular commodity in the world, are processed into coffee, which generates considerable quantity of spent coffee grounds (SCGs). However, SCGs, byproduct rich hemicellulose, poses challenge due to fermentable sugar loss during conventional pretreatment. This study investigates efficient production bioethanol from SCG using an optimized liquid hot water (LHW) pretreatment combined with separate hydrolysis and fermentation (SHF) process. LHW at 180 °C for 20 min high solid-to-liquid ratio (SLR) 1:6 (w/v) was disrupt lignocellulosic structure retain levels sugars, included mannose glucose. approach achieved concentration 15.02 ± 0.05 g/L productivity rate 1.252 g/(L·h), demonstrating efficiency this integrated Interestingly, SLR significantly reduces usage enhances product concentration, offering promising, environmentally friendly, economically viable method industrial SCGs without necessity detoxification.

To burn or valorise bark from a pulp mill: Environmental sustainability analysis using prospective consequential life cycle assessment

The Science of The Total Environment, Год журнала: 2025, Номер 976, С. 179234 - 179234

Опубликована: Апрель 9, 2025

Bark represents 10 % dry weight of spruce trees and is a major side stream from pulp production. Currently, mills burn bark to produce energy with low economic value, directly emitting biogenic carbon dioxide the atmosphere. Biorefining using continuous flow-through fractionation process generates high added-value compounds (tall oil, starch, phenol, pulp) that allow for extended storage durations. This study assesses potential future environmental impacts valorising instead burning it. We conduct LCA combining prospective consequential modelling perspective an input-related functional unit account effects storing in bark-based products. Our findings show biorefining maintains lower than combustion, reducing time-differentiated climate by up 30 %, but only when used pulping recirculated processes are integrated co-located mill supplying surplus waste energy, considered have no associated impacts. Storing longer period time has positive effect on mitigating short-term However, our analysis reveals while time-dependent decrease, there increase human toxicity ecotoxicity impacts, combustion performing better these categories. highlights importance expanding scope studies include beyond change. Overall, this work demonstrates relevant approach emerging biorefineries thus supports development sustainable circular bioeconomy.

Python-Based Algorithm for Calculating Physical Properties of Aqueous Mixtures Composed of Substances Not Available in Databases

ACS Omega, Год журнала: 2025, Номер 10(16), С. 16683 - 16694

Опубликована: Апрель 15, 2025

In this study, we developed a Python-based open-source algorithm compatible with the aqueous physical property models provided in electrolyte templates of AspenTech software. To validate accuracy model, results obtained from proposed were compared to experimental data for 37 binary mixture systems covering properties such as density, heat capacity, viscosity, and thermal conductivity. The input variables included our previous research on pure component prediction nonrandom two-liquid (NRTL) model parameters based UNIFAC simulations. This is mean absolute percentage errors (MAPE) conductivity 2.88, 0.355, 12.1, 10.1%, respectively. case density actual trends could not be accurately reflected under high-concentration conditions certain substances. addition, it was confirmed that inaccurate predictions viscosity commercial-scale falling-film evaporator simulation l-valine production led overall transfer coefficient. Therefore, caution required when predicting missing using approach significant may occur. Nevertheless, can provide an initial parameter value are existing databases without any commercial package.
