Strategies for the Transformation of Waste Cooking Oils into High-Value Products: A Critical Review

Polymers, Journal Year: 2025, Volume and Issue: 17(3), P. 368 - 368

Published: Jan. 29, 2025

Waste cooking oils (WCOs) are generated globally from households, the hospitality industry, and other sectors. Presently, WCOs mainly employed as feedstock for biodiesel energy production, strongly depending on availability of WCOs, which often imported countries. The objective this review is to give an overall comprehensive panorama impacts, regulations, restrictions affecting their possible uses producing high-value products, such bio lubricants, surfactants, polymer additives, road construction solvents. Interestingly, many reviews reported in literature that address use but a topic missing. Published studies, industry reports, regulatory documents were examined identify trends, challenges, production statistics, environmental current production. data collected show hold immense potential renewable resources sustainable industrial applications line with global carbon neutrality goals circular economy principles. However, achieving shift requires addressing gaps, enhancing collection systems, optimizing conversion technologies. This underlines need collaborative efforts among policymakers, stakeholders, researchers maximize contribute development.

Multifunctional Paf@Bc Composite Membranes for Efficient Separation, Purification, and Environmental Applications

Published: Jan. 1, 2025

To enhance the device integration and stabilization of porous aromatic framework (PAF) materials for practical applications, fabrication PAFs into membranes has emerged as a promising strategy. Herein, multifunctional composite membrane (PAF@BC) was developed by incorporating hydrophilic bacterial cellulose (BC) with PAF materials. The structural synergy between powders BC matrix creates interfacial gaps, enabling PAF@BC to achieve exceptional separation purification performance, alongside excellent reusability. exhibited high efficiency stability in intercepting both anionic cationic dyes. Additionally, leveraging intrinsic photocatalytic properties PAF, captured pollutants can be effectively degraded. Moreover, demonstrated outstanding iodine ion removal from aqueous solutions, achieving maximum filtration capacity 447.8 mg/g. In gas-phase efficiently intercepted vapor, 96% performance improvement compared pure membranes. This approach addresses prior limitations materials, such their hydrophobicity hindering effective interaction pollutants. show significant potential environmental remediation open new avenues versatile application diverse fields.

Computational and experimental study of terpolymers: spectroscopic, thermal, thermochemical, molecular property, and in silico toxicity analysis

Drug and Chemical Toxicology, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 17

Published: Feb. 28, 2025

In this study, a comprehensive analysis of the CMA2OEM-co-DVB-co-AMPS (2-(bis(cyanomethyl)amino)-2-oxoethyl methacrylate-co-divinylbenzene-co-2-acrylamido-2-methyl-1-propanesulfonic acid) and CMA2OEM-co-DVB-co-VIM methacrylate-co-divinylbenzene-co-vinylimidazole) terpolymers was conducted. The structural chemical properties were examined using Fourier transform infrared (FT-IR) spectroscopy, frontier molecular orbital analysis, electrostatic potential (MEP) maps, 1H, 13C NMR thermochemistry surface maps (TCSM), toxicity assessments, physical properties, electron localization function (ELF), total (ESP) analyses. silico analyses, quantitative structure–activity relationship (QSAR) model used for Toxicity Estimation Software Tool (TEST) ProTox 3.0, web-based virtual laboratory, oral prediction. estimates TEST showed that both exhibited low profiles. Oral prediction emphasizes may pose greater risk compared to CMA2OEM-co-DVB-co-AMPS. addition, experimental thermal characterization these also performed. These analyses have provided significant insights into applications functional terpolymers.

The Fusion of Elemental Sulfur With Waste Cooking Oil‐Based Derivatives: Beyond Renewability

European Journal of Lipid Science and Technology, Journal Year: 2025, Volume and Issue: unknown

Published: April 21, 2025

ABSTRACT Elemental sulfur (S 8 ), previously the powerhouse of modern society, and waste cooking oil (WCO) are nowadays surplus industrial by‐products from oil‐refinery food processing industries, respectively, generating growing environmental concerns economic loss. These unavoidable wastes, which inherent in aforementioned processes, cannot be minimized without substantial advances technology and/or significant modifications consumer behavior. Indeed, there ongoing research activities to enable a powerful strategy for upcycling these wastes into valuable useful products, that is, conversion high‐sulfur content polymeric materials (also known as polysulfides). Among those activities, ones focusing on utilization inverse vulcanization (IV), reverse version well‐known process, provides facile straightforward method allows use S WCO derivatives respective olefin components essential process. Thus, this mini‐review brief overview recent outcomes, challenges, opportunities valorization toward synthesis discussed. Besides, exemplary studies provided illustrate versatility applications ranging energy storage heavy metal remediation, well prospects use. Practical Applications : Beyond highlighting existing applications, review serves comprehensive guide exploring new field, paving way future development.
