This study explores the production of cellulose acetate from pretreated agave bagasse using deep eutectic solvents (DES). Optimized delignification was achieved with DES and the material was analyzed using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and crystallinity index (CrI) measurements. Cellulose acetates were produced by heterogeneous acetylation, and the degree of substitution (DS) and esterification (ED) were determined. Acetates were further analyzed by FTIR and thermal analyses, specifically thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Deep eutectic solvent pretreatments, especially using ChCl-LA and ChCl-OxA, altered agave bagasse fibers, improving cellulose accessibility. ChCl-LA DES was the most effective, removing 38.99% of lignin. Scanning electron microscopy images showed fiber roughening, and FTIR confirmed lignin deconstruction. ChCl-LA reduced polymerization to 718 and ChCl-OxA reduced it to 326. X-ray diffraction revealed increased crystallinity in all cases. The acetates reached their highest %ED and DS when choline chloride–lactic acid (ChCl-LA) was used, with a %ED of 46.11% and a DS of 2.7. ChCl-Gly, although less effective in structural modification, preserved the degree of polymerization (DP), making it suitable for applications prioritizing polymer retention. Thermal analysis of acetates showed similar results to commercial acetates. These findings highlight the versatility of DES in modifying lignocellulosic materials for industrial application.</p>","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"19 4","pages":"1143-1164"},"PeriodicalIF":3.2,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144647245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ammonia and carbon dioxide provide the anaerobic digestate with buffer capacity and these compounds are responsible for the regulation of the pH of this soil organic amendment. The present investigation used experimental and theoretical data collection to assess the feasibility of isolating ammonium bicarbonate from a complex organic matrix with 95% moisture by a conventional distillation procedure. The anaerobic digestate is a complex blend and similar behavior was expected to that of other non-ideal mixtures, such as the well-known ethanol–water solution. The design of the classical batch distillation setup to handle the anaerobic digestate relied on the modeling of the operation of the distillation column with an ethanol–water mixture, which was used to preliminarily elucidate the relations between heating power, boil-up rate, reflux ratio and separation efficiency. Equilibrium data retrieved from Aspen Plus® v12 and McCabe–Thiele methods were successfully applied to determine the minimum number of stages to isolate ammonium bicarbonate and ethanol in their respective aqueous solutions. Operation at total reflux in the distillation collum with the ethanol–water mixture resulted in an increase in the separation efficiency as the heating rate was increased. Operation at maximum reflux was necessary to retrieve pure ammonium bicarbonate crystals out of the anaerobic digestate. In the case of an aqueous solution including ammonia and carbon dioxide, optimization of the dose of antifoam was required to successfully perform the operation, owing to excessive foam formation.</p>","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"19 4","pages":"1110-1123"},"PeriodicalIF":3.2,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bbb.2776","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144647486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to its high concentration of phenolic groups, lignin has emerged as a promising candidate for natural UV protective materials. This study therefore aimed to produce nanocomposites of lignin from cashew apple bagasse, due to its wide availability and high lignin content, combined with zinc or titanium oxides for sunscreen application. Fourier transform infrared (FTIR) spectroscopy and X-ray analysis confirm interactions between lignin and zinc/titanium oxides. The resulting nanocomposites are stable, as indicated by their zeta potential (−32 mV to −48 mV). Lignin nanocomposites (LigZnO and LigTiO₂) exhibited similar antioxidant activity, though lower than that of lignin alone. Although lignin nanocomposites exhibited low sun protection factor (SPF) values in an emulsion base, they enhanced SPF in a commercial sunscreen. LigZnO (15.9) and LigTiO₂ (15.7) boosted the effectiveness of commercial UV absorbers (Parsol MCX and avobenzone), outperforming formulations with lignin alone or commercial ZnO and TiO₂. The synergistic interaction between LigTiO₂, LigZnO, and organic UV blockers reinforced thixotropy, making lignin nanocomposites a promising additive for sunscreen formulations.

Pine wood residues from sustainable forest management are transformed into bio-oil (BO) and separated into value-added chemicals with an integrated and innovative methodology. First, biomass is thoroughly characterized and the optimum operational parameters to produce BO are determined, the maximum yield being obtained at 450 °C. Second, BO is processed using a novel approach that integrates adsorption chromatography, vacuum distillation, liquid–liquid extraction, and precipitation, all of which are mature techniques at an industrial scale. This methodology offers a step forward to a more integrated strategy than current studies in the literature, allowing the simultaneous recovery of multiple chemicals rather than focusing only on the separation of a single family of compounds. The BO was divided into three fractions: (1) an acid-rich fraction, containing polar compounds with low boiling points such as acetic acid, formic acid, acetol, and furfural; (2) a sugar-rich fraction, containing polar compounds with higher boiling points like levoglucosan, 5-hydroxymethylfurfural (5HMF), and methyl cyclopentenolone, and (3) an antioxidant fraction, containing phenolic species with antioxidant properties such as phenol, guaiacol, catechol and vanillin. Elevated recovery yields were obtained: 69 wt% of the initial acetic acid with a value of 18 g·kg⁻¹ biomass, 92 wt% of the initial levoglucosan with a value of 10 g·kg⁻¹ biomass, and 65 wt% of the initial phenol with a value of 0.7 g·kg⁻¹ biomass.

The kinetics of adsorption were best explained by a pseudo-second-order (PSO) model, indicating that chemisorption is the primary mechanism at work.

Decisions on designing phytoremediation-to-biofuel value chains are even more complicated, due to the involvement of additional stakeholders, contamination impacting the types of biomass that can be grown and its yield, sparse land availability or small land plots – leading to lack of efficiency and economies of scale – and higher technology costs due to the need for contaminant separation. This paper presents a decision support system (DSS) that supports biofuel value chains design when the biomass originates from the phytoremediation of contaminated land. It integrates various tools, including geographic information system (GIS) data input, machine learning for biomass suitability assessment, supply chain optimization, evaluation of economic, environmental, and social key performance indicators, and a multicriteria method for ranking scenarios (i.e. combinations of biomass types and conversion technologies). The aim is to assist various types of stakeholders to assess the feasibility of establishing a phytoremediation-to-biofuel value chain, to decontaminate land, and to produce clean biofuels, while simultaneously considering multiple environmental, social, and economic criteria. A case-study application in Greece is also presented and the findings are discussed.
