Nevertheless, the proposed biorefinery structures must be evaluated to determine whether they offer more environmentally sustainable alternatives to current practices. This research aims to assess the potential environmental impact of corn stover (CS) valorization within the framework of the planetary boundaries (PB). Three CS valorization scenarios were proposed and compared with a base case scenario, where CS is traditionally used as mulching in the Sucre region of Colombia. The valorization alternatives were modeled and evaluated using Aspen Plus V14.0 and SimaPro V8.3, relying on the PB-Life Cycle Assessment methodology to quantify the level of PB transgressions. Results showed that the Scenario 0 of CS utilization as mulching remained within the downscaled safe operating space. Notably, biochar utilization in Scenario 1 showed positive results as a carbon sequestration strategy to reduce the environmental impact of CS transformation processes at the PB of climate change. In contrast, Scenario 2, focused only on xylitol production, exceeded the PB for climate change and ocean acidification owing to increased emissions from higher energy needs. These findings highlight the importance of integrating CS valorization processes with biochar conversion, exploiting its potential for agricultural remediation and long-term carbon sequestration. Such practice could enhance the environmental sustainability and feasibility of biorefineries, ensuring they operate within the PB limits while maximizing resource efficiency.</p>","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"19 5","pages":"1411-1424"},"PeriodicalIF":2.9,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100920","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}

Although the PSILCA approach identifies social hotspots effectively, reliance on generic data may not accurately represent the local context.

Traditional organic solvents used for phenolic extraction can be toxic and are highly flammable, raising environmental concerns. In contrast, natural deep eutectic solvents (NADES) present a greener alternative, as they are formed through hydrogen bonding between donors like sugars, amines, carboxylic acids, amino acids or alcohols, and acceptors like quaternary amines. The number and strength of these hydrogen bonds influence the physicochemical properties of NADES, and these in turn influence the extraction efficiency and selectivity of phenolic compounds. This study aimed at understanding how the physicochemical properties of NADES, particularly polarity, viscosity, conductivity and pH, affected the extraction efficiency of phenolic compounds from grape seeds, their antioxidant activity and the selectivity toward reducing sugars, compared with a hydroalcoholic solvent. NADES with different physicochemical properties were chosen, namely choline chloride with 1,2-propanediol, urea or malic acid, and at varying water contents (25, 50 and 75% w/w). The highest extraction efficiencies were obtained with 1,2-propanediol (TPC 5.13% DW) and malic acid (TPC 5.11% DW) at 50% water. Polarity was found to be a key property as matching the polarity of NADES to that of the target molecules led to improved extraction efficiency.

Furfural, 5-hydroxymethylfurfural (5-HMF), and 5-methylfurfural (5-MF) are furans that can be obtained by carbohydrate dehydration under acidic conditions at elevated temperature and pressure. One of the mechanisms to produce these compounds from lignocellulosic materials relies on prior fractionation of biomass carbohydrates and further dehydration catalysis. However, this is a costly and technically challenging method and it would be advantageous to develop a one-pot conversion mechanism that facilitates simultaneous biomass fractionation and conversion to furans. <i>Ulva lactuca</i> is an alga that has the advantage of being lignin-free and rich in glucose, rhamnose, and xylose, which are ideal for producing 5-HMF, 5-MF, and furfural, respectively. The high diversity of sugar constituents is also relevant for the production of added-value oligosaccharides. Catalysis with inorganic salts has been reported as a successful tool for biomass upgrading to furans when combined with hydrothermal pretreatments, and could provide a cheap and environmentally friendly one-step methodology for furan production. This study therefore aimed to investigate the effect of hydrothermal and dilute acid pretreatments, as well as treatment with inorganic salt solutions (ferric chloride, ferric nitrate, and aluminium nitrate) on <i>U. lactuca</i> biomass to produce oligosaccharides, monosaccharides, and furans (furfural, 5-HMF, and 5-MF). These methods resulted in a maximum sugar solubilization of 65% in non-salt-assisted hydrothermal pretreatments and 84% in salt-assisted hydrothermal pretreatments, with inorganic salt catalysis also resulting in 100% xylose, 36% glucose, and 46% rhamnose conversion to the respective furans.</p>","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"19 5","pages":"1308-1325"},"PeriodicalIF":2.9,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145102178","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}
