Spent coffee ground (SCG) is the residue obtained during the brewing process. It represents an abundant source of energy biomass, or raw material for added value products but it is still largely unexploited. This residue may find several applications, such as in polymers/composites precursors, solid/liquid biofuels, biofertilizers, and so forth. The aim of the present paper was the pilot production of pellets by mixing SCG and other residual biomass feedstock. Coffee residues were mixed at different ratios (0, 10, 30, 50, 70, 90 wt%) together with: (i) forestry residues; (ii) sawmill residues; (iii) urban prunings; (iv) maize residues; (v) peach prunings; and (vi) miscanthus. Samples of each fuel mixture were analyzed at the Solid Fuels Laboratory of CPERI/CERTH (Chemical Process and Energy Resources Institute/Centre for Research and Technology Hellas) in Greece by applying established standards. The results of the analyses show that the mixing of biomass residues with coffee could result in competitive solid biofuels. More specifically, pellets with up to 10% coffee residues, mixed with sawmill residues, complied with the class A2 limits set by the international standard ISO 17225-2 for wood pellets, and pellets with up to 30% coffee residues complied with the class B limits for wood pellets for commercial/residential applications. Urban prunings mixed with 10 wt% coffee residues are within the limits set for class B wood pellets.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"18 4","pages":"968-989"},"PeriodicalIF":3.2,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bbb.2646","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141340104","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}

These leather wastes have a high fat content, which could be used for valuable products. This study focuses on the conversion of such fats into a biocrude to be distilled into a bio-based hydrocarbon fuel blendstock. A biorefining technology defined as ‘gas-phase catalytic cracking’ (GCC) over activated carbons, also referred to as ‘greasoline’, was used for conversion, and GC–MS/FID and simulated distillation for product characterization. The experiments were performed at ambient pressure and 450 °C reaction temperature, with 40 g h−1 of fat being processed over 55 g of steam-activated carbon under a nitrogen atmosphere for a duration of 4 h. Fleshing oil obtained from the pre-fleshing of double-face lambskins by extraction with supercritical CO2 yielded almost the same mass fraction of organic liquid product (OLP) (59 wt%) as palm oil used as a reference (62 wt%). In both OLPs, n-alkanes from heptane to heptadecane predominate, with a clear predominance of n-pentadecane and n-heptadecane and no unsaturated molecules among the major components. For both oils, about 85 wt% of the OLP is in the boiling range of diesel fuel, and about another 12 wt% is in the gasoline boiling range.

This study explored the synergistic effect achieved by combining chicken feathers with elephant grass to create a composite feedstock for biochar production. The biochar was subjected to liquid-phase exfoliation using acid and acetone. Elemental analysis indicated that the co-carbonization of the combined biomass produced an enriched hybrid biochar. The oxygen content in both exfoliation routes (acid and acetone) increased, with an increase and decrease in carbon content in acetone and acid exfoliation, respectively. Textural analysis revealed significant enhancement, with surface areas of the acid-exfoliated biochar more than twice the size of the hybrid biochar. The pore volume of both exfoliated samples was double that of the hybrid biochar. Microscopic surface examination revealed rougher, porous structures in the exfoliated biochars in comparison with the smooth, cohesive surface in hybrid biochar. Functional group analysis showed the presence of aromatic rings, a carbocyclic group, and an alkene, suggesting potential applications in adsorption.

The full process included acid–base treatments, phase separation, and adsorption, and the glycerol purity and recovery were optimized by varying the pH during saponification and acidification, the solvent-to-glycerol ratio, and type of base used in the process to enhance both. The testing campaign resulted in a final purity of up to 87% wt starting from a very low-quality ‘end-of-life’ waste glycerol sampled from different refineries. The net glycerol recovery at laboratory scale reached 42% of the initial glycerol in the feedstock and the maximum ash removal exceeded 90% given the low quality of the feedstock and high content of impurities and the attempt to achieve high glycerol recovery. The experiment showed that mild operations such as saponification with KOH (pH of 8), acidification with H3PO4 (pH of 6), an ideal 2-propanol to glycerol volume ratio equal to 3 and potassium hydroxide as a base for the neutralisation step were the optimum conditions despite the differences between samples.

However, it is unclear how these additives would affect engine operation. The effects of commercial nanoadditives on engines have been the subject of several studies. The current study focuses on nanoparticles derived from agricultural waste – specifically rice husk (RH) – to enhance their value. This study therefore examined silica (SiO2) doped with Adansonia digitata methyl ester (ADME) and tested it in a diesel engine. All nanofuel blends were prepared using an ultrasonication process, incorporating 400 ppm of SiO2 nanoparticles, fuels, and 1% surfactants. The results revealed that the brake thermal efficiencies (BTE) at maximum brake power (BP), for B20, B20 + SiO2, B100, and B100 + SiO2 fuels, were 29.9%, 28.2%, 28.44%, and 27.1%, respectively. Brake-specific fuel consumption (BSFC) was also reduced when the engine ran from 4 to 16 kW BP. The exhaust gas temperature (EGT) of B100 and B100 + SiO2 increased more than that of B20. The peak heat release rates (HRR) of the B100 + SiO2 and B20 + SiO2 were slightly higher by 2.9% and 2.6%, respectively than the neat B100 at medium BP. However, in-cylinder gas pressure (CGP) increased in the following order: B20 + SiO2 < B20 < B100 < B100 + SiO2 < B0. Moreover, the exhaust emissions of nanofuel blends showed a greater reduction in CO, total hydrocarbon (THC), CO2, NOX, and particulate matter (PM) in comparison with B20 and B100. Overall, this study recommends that SiO2 nanoadditive is a beneficial substitute fuel additive to use with biodiesel and its blends due to enhanced engine performance efficiency and reduced emissions.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"18 5","pages":"1437-1454"},"PeriodicalIF":3.2,"publicationDate":"2024-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142123339","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}

Co-liquefaction provides a viable alternative for managing plastic waste while contributing to biofuel production. The purpose of this article is to provide a comprehensive review of the advances in the co-liquefaction of various mixtures of plastic waste and different types of biomass feedstocks (lignocellulosic and algal) for the production of biofuels.The influence of various reaction parameters, such as feedstock composition (blending ratio), temperature, catalyst type and loading, solvents, and reaction time on the product yield are explored. The synergistic interaction during the co-liquefaction of biomass and plastic and the distribution and properties of biofuel products are also discussed.The findings demonstrate that maximum product yields vary depending on the final temperature, and the blending ratio plays a crucial role in determining the distribution of liquefaction products. Of particular interest is biocrude oil, the components of which are influenced by the composition of the feedstock material. The distribution of organic elements in the biochar is contingent upon the type of plastic used. Although the analysis of gas-phase components is often overlooked, the reaction medium's composition is shown to impact the resulting gas composition.Finally, based on the insights gleaned from the literature, this review presents future perspectives on the subject matter. In general, the co-liquefaction process offers a viable option for sustainable biofuel production and is a promising approach to address the waste plastics disposal challenges effectively, contributing to the valorization of plastic waste to achieve a circular bioeconomy in the future.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"18 5","pages":"1799-1820"},"PeriodicalIF":3.2,"publicationDate":"2024-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bbb.2641","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142123411","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}

Xylose is a precursor for various biochemicals. However, the recalcitrant nature of ANH makes saccharification more complex. To address this, lime and acid pretreatments were carried out to enhance the susceptibility of biomass to saccharification. Before this, a compositional analysis was conducted to determine the initial constituents of the feedstock. Saccharification was conducted under the following conditions: 2% (wV−1) substrate loading, 100 rpm agitation, and 30 °C hydrolysis temperature for 12 h hydrolysis time at pH 4.5 to 5.0. However, parameters like xylanase enzyme loading were varied to enhance the saccharification of the ANH. The results demonstrated that acid-treated husk (ATH), lime-treated husk (LTH), and raw husk (RH) achieved the highest yield (gg−1) of reducing sugar, approximately 90, 83, and 15%, respectively, at an enzyme loading of 15.0 IUg−1. Various analytical techniques, including Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), zeta potential, thermogravimetric analysis (TGA), X-ray diffraction (XRD), and field emission scanning electron microscopy (FESEM) were used to examine structural changes in the native, pretreated, and saccharified residues of ANH. The analysis revealed that a significant amount of partial crystalline and amorphous cellulose in the ANH biomass was hydrolyzed during the saccharification process. However, saccharification also led to the removal of amorphous substances, disruption of the crystalline structure, and conversion of crystalline regions into amorphous domains.","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"18 5","pages":"1495-1510"},"PeriodicalIF":3.2,"publicationDate":"2024-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142123410","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}

The present study highlights the economic application of different Dunaliella species and the available sustainable technologies for the cultivation, harvesting, and extraction of bioactive compounds that have the potential for commercial scaleup. Their incorporation into biorefinery processes can reduce dependency on energy-intensive and low-yield processes.This review briefly discusses the technoeconomic analysis (TEA) of Dunaliella-driven industrial approaches for the optimization of effective yield and determination of final production costs.

The authors have comprehensively deliberated different aspects of Dunaliella from physiological to industrial applications, meanwhile underscoring the existing knowledge gaps that impede the success of Dunaliella biorefineries. The current industrial methods being employed for biorefineries are limited to producing individual bioproducts, which may not be fully cost effective, making them less competitive in the global market.

Understanding and modeling of hydrothermal liquefaction is currently mostly based on a simplified biochemical analysis and product yield data. This paper presents a large dataset of 2439 experiments in batch reactors that were extracted from 171 publications in the scientific literature. The data include biochemical composition data such as fiber content and composition, proteins, lipids, carbohydrates, and ash. The experimental conditions are recorded for each experiment as well as the reported yields. The objective of this paper is to make a large database available to the scientific community. This database is analyzed with machine-learning tools. The results show that there is no consensus on the analysis techniques, experimental procedures, and reported data. There are many inconsistencies across the literature that should be improved by the scientific community. Machine-learning tools with a large dataset allow the generation of reliable yield production tools with a large application field.
