Its acquisition involves acid hydrolysis, resulting in a challenging separation and purification process due to the formation of a dilute azeotropic mixture. This complexity renders separation costly and presents a hurdle for large-scale production. Various purification methods, including hybrid and intensified systems, have been proposed to address this issue. However, a systematic synthesis methodology incorporating multi-objective optimization considering economic and environmental factors has yet to be applied to this mixture. Hence, this study employs such a methodology to derive sustainable and thermodynamically feasible intensified designs. The optimization algorithm employed is differential evolution with a tabu list. Two objectives are considered: total annual cost as the economic criterion and the eco-indicator 99 as the environmental index. The intensified design, incorporating thermal coupling, presents the best results of the designs studied, with a total annual cost value of $13.9 million and 4.21 × 10<sup>9</sup> environmental points per year. This represents an economic saving of $4.6 million per year and reduces environmental impact by 1.15 × 10<sup>9</sup> points compared to the reference design, providing a sustainable alternative for purifying levulinic acid at a cost of $0.261 per kilogram.</p></div>","PeriodicalId":487,"journal":{"name":"BioEnergy Research","volume":"17 3","pages":"1724 - 1738"},"PeriodicalIF":3.1,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140883062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It analyzed three 24-year scenarios based on primary data collected from the mixed product harvest with whole tree harvesting systems that primarily produce clean chips, dirty chips, or pulpwood and dirty chips. Using a joint product costing approach, proportional costs of shared processes were allocated to different products on a mass basis. Uncertainty associated with key stochastic variables was incorporated into the model to generate net present values (NPV), benefit–cost ratios (BCR), and minimum selling prices (MSP) via Monte Carlo simulation. The clean chip scenario produced an NPV of $1.36 million and a BCR of 1.03, while the pulpwood scenario’s NPV and BCR ($0.06 million and 1.02) were lower, and the dirty chip scenario generated negative NPV (− $0.02 million) and a BCR of 0.99. The probabilities of achieving positive NPVs for all three scenarios fell between 47 and 56%. The mean MSP for one clean chip scenario was $94.03/dry Mg, while the mean MSPs for two dirty chip scenarios were $74.79/dry Mg and $75.93/dry Mg. NPV results were most sensitive to forest biomass feedstock harvesting production levels, transportation distances, and delivered prices, followed by diesel fuel consumption for in-wood harvest and diesel fuel price.</p></div>","PeriodicalId":487,"journal":{"name":"BioEnergy Research","volume":"17 3","pages":"1739 - 1754"},"PeriodicalIF":3.1,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140883210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bio-oil extraction has largely focused on regular bio-oils (~ 33 wt% O) and partially deoxygenated oils (< 12 wt% O). Furthermore, it is desired to extract phenolics without direct distillation of bio-oils, which would enable extraction from the heaviest portion of bio-oil. Mid-level oxygen (MLO) bio-oils (16–25 wt% O) produced from switchgrass were characterized for their ability to separate into phenolic-rich fractions. Toluene-soluble portions of the oils underwent NaOH extraction to extract one-ring phenolics, while toluene-insoluble portions were fractionated with iso-propyl alcohol (IPA). While phenolic extraction proceeded without distillation (having been a prerequisite for partially deoxygenated bio-oils), the efficiency of extraction was less than optimal, owing to the presence of other oxygenated compounds in the hydrocarbon-rich fraction. Both IPA-insoluble and IPA-soluble fractions underwent solvent liquefaction reactions with base additives. While using water as a reaction medium produced greater concentrations of phenols than when using methanol, addition of sodium carbonate produced narrower product distributions of phenols and inhibited formation of benzenediols.</p></div>","PeriodicalId":487,"journal":{"name":"BioEnergy Research","volume":"17 3","pages":"1784 - 1793"},"PeriodicalIF":3.1,"publicationDate":"2024-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140655990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conversion of fish waste to economically important and eco-friendly products will make fishing and fish processing more valuable and sustainable. This study evaluated waste residues from fish processing waste subjected to conventional physical extraction of fish oil for single-cell oil production using oleaginous yeast. Potential application of the single-cell oil to produce biodiesel was evaluated. The treatment containing fish waste residue (5%, w/v) and glucose (20 g/L, w/v) displayed the highest rate (14%) of total lipid generation.

At 15% (w/v) fish waste residue and 20% (w/v) glucose amendment of the medium, the highest biomass production was observed. The yeast bio-oil has a lipid profile like vegetable oils and consists of mainly long-chain fatty acids (between C14 and C24) which are suitable for biodiesel production. The most abundant fatty acids were palmitic acid (C16:0), elaidic acid (C18:1n-9t), and stearic acid (C18:0). FTIR analysis of the transesterification reaction product using the yeast oil confirmed its conversion to biodiesel.

The results showed the potential of electric energy and heat that could be generated by burning the biomass in a CHP system. Also, they presented the respective avoided greenhouse gas emissions in situations where biogas is applied to replace conventional heat or electricity sources.

The experimental data obtained was subjected to calculations that indicate an electric generation of 202.98 kWh/ton of cambuci biomass and heat generation of 913.40 MJ/ton of cambuci biomass. In this theoretical scenario, for each ton of cambuci, it is possible to produce 913.4 MJ of thermal energy and 202.98 kWh of electric energy, considering the biogas burning into a CHP system. In the analysis of types of substrates regarding growth capacity, it was concluded that the substrate with a 30% dilution of the digested end was the one that showed the best growth of the cultivar’s stem, obtaining a CEC of 9.1516 mol/g.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":487,"journal":{"name":"BioEnergy Research","volume":"17 3","pages":"1375 - 1385"},"PeriodicalIF":3.1,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140609034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
