The main objective of this research study was to extract novel natural fibre and filler from biomass wastes and examine their influence on the load bearing properties of epoxy-based composite. The study begins with synthesis of reinforcements and fabrication of composite plates, inclusion of finger millet husk biosilica of 1, 3, 5 vol.% and fibre of 30 vol.% by hand layup method. The tests were conducted as per American Society of Testing and Materials (ASTM) standards. The evaluation provided critical insights that the influence of fibre and biosilica improved the fatigue resistance. The composite N3 with 3 vol.% biosilica and 30 vol.% of fibre exhibited higher fatigue cycle count of 24,093 for 30% of ultimate tensile stress (UTS). Similarly, creep results elucidate that the N4 composite designation delivers low creep strain about 0.0108, 0.0132, 0.0154, 0.0248, and 0.045 for time intervals of 2000, 4000, 6000, 8000, and 10,000 s, respectively. Moreover, it is noted that the presence of biosilica reduced the flammability of composites. The N4 composite designation exhibits comparatively low flame propagation speed of 6.8 mm/min with V-0 grade. The ANOVA results concluded that the results obtained are significant with a P value of 2.7e − 8. Based on the results the novel cellulose fibre improved the load bearing effect along with biosilica of 3 vol.%. However, beyond 3 vol.% of biosilica reduced the load bearing properties. The findings underscore the potential of these composites as sustainable, durable, and fire-safe alternatives for applications ranging from structural engineering to automotives, drones, and defence sector.","PeriodicalId":488,"journal":{"name":"Biomass Conversion and Biorefinery","volume":"25 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141948357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research envisages to develop an eco-friendly solution by creating biodegradable composite pots from banana peels. Banana peel powder and deoiled rice bran plasticized by cashew nut shell liquid and glycerol into pellets. Pellets were molded into pots using injection molding at suitable temperature and pressure. Processing resulted in significant changes in physical properties of the pot and raw materials. CNSL and biopolymers demonstrated strong physical interaction during the construction of a 3D network of pots. The novelty of the work lies in its innovative integration of waste management and sustainable product development. By employing principal component analysis (PCA) for characterization and classification, the research introduces a sophisticated analytical method to evaluate the properties and performance of the composite material. The pots made from 12% CNSL exhibited better mechanical and physical properties in comparison to pots made from glycerol. However, water binding capacity, porosity, and water solubility index (WSI) were higher in pots containing glycerol. SEM analysis evidenced a homogeneous and smoother surface in pots with CNSL. Pots with 12% GL and 12% CNSL degraded in 17 and 15 weeks, respectively.

Most plasticizers are synthetic and have liquid formulations that are equally hazardous. Bio-based sources are abundant in glycols, glycerol, and polyphenols, which, when chemically treated, make them effective plasticizers. This study extracted a solid plasticizer from the lemon grass residue. We applied chemical treatments to the lemongrass residue, which included alkali treatment, the reflux process, flocculation, and purification. We subsequently subjected the obtained solid plasticizer to physiochemical investigation and Fourier transform spectroscopy for characterization. The plasticizer has a low density of 0.982 g/cm3 and an average yield of 35.5%. The X-ray diffraction study revealed that the crystallites measured 15.03 nm in size and had the lowest crystallinity index (45.5%). The scanning electron microscopy study revealed that the plasticizer exhibited a honeycomb structure. The UV analysis of plasticizers reveals active absorption, similar to liquid plasticizers like glycerol and glycols. The glass transition temperature of the plasticizer, 87.67 °C is obtained using differential scanning electron microscopy analysis. The roughness parameters exhibit a clear orientation in the extracted plasticizer. This solid plasticizer was dissolved in water and added as a plasticizer in M30-grade cement concrete, up to 6% by weight of cement. We discovered that adding 6% bioplasticizer to the concrete improved its slump and compressive strength by 1.5% and 5%, respectively. As a result, the characteristics of plasticizers boost their utility in the construction sector.","PeriodicalId":488,"journal":{"name":"Biomass Conversion and Biorefinery","volume":"7 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141969817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sodium carbonate (Na2CO3) was used to modify PG to explore the safe and rational utilization of PG. The modified phosphogypsum biochar (MP-BC) was prepared by mixing the modified phosphogypsum (MPG) with pineapple peel in proportion and applied to the removal of fluoride from wastewater. The X-ray fluorescence spectrum and X-ray diffraction pattern indicate that the chemical component of MP-BC is mainly calcium oxide, that is, an appropriate amount of modified PG (MPG) can load calcium oxide on biochar, thereby improving the physical properties of biochar. The MP-BC exhibited 133 mg/g maximum fluoride adsorption capacity, and the adsorption rate of fluoride in actual phosphogypsum leachate by MP-BC can reach 97.23%. Furthermore, chemical precipitation was the primary adsorption mechanism. Also, the MP-BC can effectively promote fluoride ion conversion into calcium fluoride. In summary, this study proposes a method of green utilization of PG, which effectively alleviates PG pollution, promotes the reuse of PG, and realizes the “treating waste with waste” of industrial waste.","PeriodicalId":488,"journal":{"name":"Biomass Conversion and Biorefinery","volume":"54 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141948360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While various remediation methods exist, they often lack scalability and sustainability. Biochar has emerged as a promising solution due to its eco-friendly nature and multifunctional properties. In particular, engineered biochar, modified to enhance its surface area and functional groups, exhibits superior performance in heavy metal adsorption. Biochar’s diverse morpho-physicochemical features, such as increased surface area and cation exchange capacity, facilitate heavy metal adsorption through various processes. The choice of feedstock materials and modification methods significantly influences biochar’s sorption capacity. Numerous reviews address the toxicity and treatment methods for heavy metals in soil and water. This study aims to advance the research by identifying key challenges and offering insights into engineered biochar production, characteristics, and applications for heavy metal cleanup in soil and water ecosystems. By exploring biochar potential with suitable interventions, we can develop sustainable solutions to mitigate metal toxicity and protect environmental and public health.

XOS display great thermostability (100 °C) and strong acid resistance over a pH range (2–7), making them suitable for gastrointestinal administration given their potential to tolerate gastric acid. XOS improves digestion and nutrient absorption while also providing health advantages by inhibiting the formation of harmful microorganisms. XOS, generated from lignocellulosic biomass (LCB) through enzymatic or chemical hydrolysis, have significant prebiotic characteristics and broad applications in medicine, food, and health. The XOS purification has become crucial to their subsequent industrial application. Still, it needs further exploration to lower costs and increase the purity of the XOS-supplemented diet. It benefits host wellness in numerous ways because of its immunomodulatory, growth-regulating, anticancer, antibacterial, antioxidant, and other bioactive compounds. Collaboration among researchers, industry stakeholders, and policymakers is critical for converting research findings into practical implementations. An academic search engine (Web of Science) was accessed to identify the most relevant literature on the XOS derived from agro-waste. Additional information was obtained from SCOPUS and Google Scholar databases. This review paper explores developments in agro-waste-derived XOS and its potential as an ingredient in food, cosmetics, pharmaceuticals, and the agriculture sector. The review also highlights its production and purification methods as well as health benefits. Furthermore, the global market potential of XOS creates a vision for extensive areas of growing impact in the field.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":488,"journal":{"name":"Biomass Conversion and Biorefinery","volume":"29 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141948355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aimed to optimize acidic demineralization using various HCl concentrations of 1, 2, 3, 4, 5, and 10% on chitosan extraction and characterization of morphological and physicochemical properties. Chitosan production with a high deacetylation degree (89.7–93.8%) for all samples was confirmed by FT-IR spectroscopy compared to commercial chitosan. The ash content, moisture content, and chitosan yield were in the ranges of (0.24–0.89%), (0.26–5.1%), and (15.1–51.3%), respectively. Furthermore, XRD showed that commercial chitosan had a completely amorphous structure. In contrast, the isolated chitosan samples showed a low crystallinity index (3.57–19.58%) due to the formation of natrite (Na2CO3) and thermonatrite (Na2CO3.H2O) as indicated by SEM–EDS. Additionally, this study found that chitosan production can be optimized from white Pacific shrimp shells (Litopenaeus vannamei) with high resemblance to commercial chitosan using the optimal acidic demineralization concentrations of 1–3% hydrochloric acid at room temperature under stabilized conditions of deproteinization and deacetylation processes. Furthermore, future research will focus on optimizing the deproteinization and deacetylation stages of the chemical extraction of chitosan using the optimal demineralization conditions found in the current study. Additionally, utilizing the byproducts of the chemical extraction stages as liquid fertilizers in agriculture develops an integrated industrial sustainable solution for shrimp waste management.","PeriodicalId":488,"journal":{"name":"Biomass Conversion and Biorefinery","volume":"71 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141948358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultrasonication experiments were carried out to optimize the process for recovering antioxidant-rich bioactive compounds from P. gymnospora by employing sample-to-solvent ratio and extraction time as independent variables using response surface methodology. A second-order response surface regression model was developed as a function of sample-to-solvent ratio and extraction time, and the optimum extraction condition was obtained by the desirability function. Biomass obtained after the ultrasonication process was then subjected to alginate extraction using the citric acid–based method (2 and 4%) as a step toward cascaded biorefinery. Employing a 2% citric acid–based method has shown improved viscosity of 5.41 cP and a higher zeta potential value of − 48.13 mV with a lower Polydispersity Index value of 0.359. Taking into consideration the commercial significance of natural antioxidants and alginate, the method developed can have significant implications in the food and nutraceutical industry. Further, the technology employed, viz., ultrasonication for seaweed extract production and citric acid for alginate extraction, is a greener process pointing toward the promising possibility of designing a greener biorefinery approach for seaweed biomass utilization.","PeriodicalId":488,"journal":{"name":"Biomass Conversion and Biorefinery","volume":"18 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141969832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
