Hydrolytic Decomposition of Corncobs to Sugars and Derivatives Using Subcritical Water

Processes, Journal Year: 2025, Volume and Issue: 13(1), P. 267 - 267

Published: Jan. 18, 2025

Corncobs are a widespread and renewable by-product of corn cultivation that typically considered waste or low-value material. contain hemicellulose, cellulose, lignin, which can be converted into valuable products using suitable techniques. Subcritical water is increasingly used as green medium for the extraction components from biomass, it has many advantageous properties (high yield, pure extracts, shorter times) compared to other organic solvents. For this reason, subcritical was in study extract corncobs at different temperatures (150–250 °C) reaction times (10–60 min). During decomposition corncobs, numerous formed aqueous phase depending on temperature time. In addition sugars their derivatives, phenolic compounds were also formed, great importance applications. It found low (150–170 hemicellulose begins decompose and, particular, (glucose, xylose, arabinose, galactose) initially phase. Higher (200 250 more favorable components. The yield increases with due degradation cellulose content lignocellulosic biomass. At same time, several new (furfural, 5-hydroxymethylfurfural (5-HMF), 1,3-dihydroxyacetone, levulinic acid, formic acid well components) through lignin further sugars. most important certainly furfurals, central platform compounds. highest furfural reached 200 °C 60 min accounted almost half all (472.01 ± 5.64 mg/g dry extract). These biomass-derived derivatives production fuels, pharmaceuticals, biodegradable polymers, surfactants.

Phytochemical Profiling and Anticancer Potential of Pistachio Wastes Against MCF-7 Breast Cancer Cells: A Metabolic and Apoptotic Pathway Analysis

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: March 3, 2025

Food waste poses significant environmental, economic, and social challenges worldwide. Pistachio is recognized for its health benefits, particularly anticancer properties. This study assessed the phytochemical characteristics of pistachio hull (PH) shell (PS) using various solvents (ethyl acetate, hexane, methanol). Methanolic extracts showed substantially higher phenolic flavonoid contents along with enhanced antioxidant activity across all tested methods, PH consistently outperforming PS in Cell viability tests on MCF-7 cancer cells indicated that PH-Hexane had a slightly greater effect than PH-ethyl acetate PH-methanol. cycle analysis revealed notable arrest G0/G1 phase compared to control group. Additionally, treatment resulted 21.24% apoptosis, primarily early apoptosis at 19.41%. The pathway involving 46 genes induces by modulating several metabolic pathways, those associated immune system, developmental biology, signal transduction, cellular responses stimuli. induction was characterized substantial upregulation CEBPB, HIF1A, MYC downregulation ATF2, CEBPA, NR3C1 genes. findings this indicate hexane extract derived from high-oil-content wastes has potential as an agent. Future research oil-rich plant-based should consider utilizing solvent further exploration

Utilizing Agro-Waste as Aggregate in Cement Composites: A Comprehensive Review of Properties, Global Trends, and Applications

Materials, Journal Year: 2025, Volume and Issue: 18(10), P. 2195 - 2195

Published: May 9, 2025

Amid growing environmental concerns and the increasing demand for sustainable construction practices, exploration of alternative materials in building applications has garnered significant attention. This paper provides a comprehensive review use agricultural waste as an aggregate cementitious composites, with particular focus on palm kernel shells, coconut hazelnut, peanut pistachio stone fruit shells pits, date grape seeds, rice husks, maize (corn) cobs, sunflower seed shells. For each type agro-waste, discusses key physical mechanical properties, global production volumes, primary countries origin. Furthermore, it offers in-depth analysis existing research incorporation these into cement-based highlighting both advantages limitations their use. Although integration agro-waste presents certain challenges, vast quantities residues generated globally underscore urgency potential reuse. In line circular economy principles, this advocates valorization through innovative within industry.

Degradation of Waste Tetra Pak Packaging with Hydrothermal Treatment in Sub-/Supercritical Water

Polymers, Journal Year: 2024, Volume and Issue: 16(13), P. 1879 - 1879

Published: July 1, 2024

Tetra pak packaging is one of the most frequently used types in food industry. The recycling tetra waste presents a difficult task because its multi-layered, multi-component structure. In this study, degradation subcritical (SubCW) and supercritical (SCW) water was investigated. experiments were carried out or two stages (SubCW SCW), whereby influence reaction temperature time on yield composition products obtained maximum oil phase achieved one-stage two-stage process 60.7% 65.5%, respectively. gas phases composed different hydrocarbons. Higher longer led to higher amounts saturated aliphatic hydrocarbons both phases. aqueous contained sugars (glucose, fructose) sugar derivatives (levulinic acid, glyceraldehyde, furfurals). Based these results, pathway SubCW SCW proposed. results study show that with promising process.
