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

Polymers, Год журнала: 2025, Номер 17(3), С. 368 - 368

Опубликована: Янв. 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.

Waste Cooking Oils into High-Value Products: Where Is the Industry Going?

Polymers, Год журнала: 2025, Номер 17(7), С. 887 - 887

Опубликована: Март 26, 2025

Waste cooking oils (WCOs) are generated globally in significant amounts by various sectors including hospitality, households, and industrial operations. Many nations currently lack dedicated legislation for managing WCOs, creating a pressing environmental challenge. At present, WCOs primarily utilized industries as raw materials biodiesel production energy generation. However, their role second-generation is contingent on availability, often necessitating imports of either or from other countries. The European Union has emphasized the importance prioritizing biowaste high-value alternative products beyond to achieve carbon neutrality 2050. reviews have been published literature reporting potential WCO applications produce biolubricants, biosolvents, animal feed, asphalt additives, among others, however, no detailed analysis trends ever presented. Within this panorama, unlike existing that focus specific polymer classes derived work sought present comprehensive overview use polymeric fuel energy, providing general patents (or alive) last 10 years, together with which innovative being introduced sold market today.

Bio-Oil-Based Epoxy Resins from Thermochemical Processing of Sustainable Resources: A Short Review

Journal of Composites Science, Год журнала: 2023, Номер 7(9), С. 374 - 374

Опубликована: Сен. 6, 2023

Epoxy is the most prevalent thermosetting resin in field of polymer composite materials. There has been a growing interest development bio-based epoxy resins as sustainable alternative to conventional petrochemical resins. Advances this recent years have included use various renewable resources, such vegetable oils, lignin, and sugars, direct precursors produce In meantime, bio-oils produced via decomposition biomass through thermochemical conversion mainly being used liquid fuels. It noteworthy that can be resource This review addresses research progress producing bio-oil-based from processing techniques including organic solvent liquefaction, fast pyrolysis, hydrothermal liquefaction. The production bio-oil its inject sustainability into are discussed. Herein, we intend provide an overall picture current attempts area resins, reveal their potential for stimulate interests green/renewable

The general requirement of replacing petroleum-derived plastics with renewable resources is particularly challenging for new technologies such as the additive manufacturing photocurable resins. In this work, influence mono- and bifunctional reactive diluents on printability performance resins based acrylated epoxidized soybean oil (AESO) was explored. Polyethylene glycol di(meth)acrylates different molecular weights were selected viscosity mechanical properties their binary mixtures AESO. Ternary containing 60% AESO, polyethylene diacrylate (PEGDA) polyethyleneglycol dimethacrylate (PEG200DMA) further improved properties, water resistance resin. Specifically, terpolymer AESO/PEG575/PEG200DMA 60/20/20 (wt.%) modulus (16% increase), tensile strength (63% increase) %deformation at break (21% respect to pure enhancement provided by proven Jacobs working curves accuracy printed patterns. proposed formulation, a biorenewable carbon content 67%, can be used matrix innovative unrestricted applicability in electronics biomedical fields. However, much effort must done increase array bio-based raw materials.

Eugenol-Based Siloxane-Containing Recyclable Epoxy Resins with Tunable Dynamic Properties, Reprocessability, and Degradability

ACS Sustainable Chemistry & Engineering, Год журнала: 2024, Номер 12(46), С. 16976 - 16985

Опубликована: Ноя. 8, 2024

Developing recyclable and biobased thermosetting polymers is of great significance for environmental protection resource recycling. In this work, three liquid eugenol-based siloxane-containing epoxides (ESI1–3) with different rigid side groups functionalities were synthesized cured by anhydride or amine hardeners. The epoxy resins the hardener (ESI-M) show quite dynamic properties, reprocessability, degradability compared to those (ESI-H). Bifunctional (ESI1 ESI2) anhydrides exhibit significantly faster stress relaxation at lower temperatures amines. All can be reprocessed hot pressing due their structures. Both ESI1-M ESI2-M almost fully restore mechanical properties after reprocessing. However, ESI1-H ESI2-H poor reprocessability even when pressed high temperature. ESI degrade rapidly in a tetrabutylammonium fluoride trihydrate/tetrahydrofuran solution, but they distinctly degradation behaviors acidic solutions. Notably, degraded ESI-H HCl solution recycled prepare new resins, whose tensile strengths are comparable original resins. Finally, carbon fiber reinforced composites electromagnetic wave absorbing coatings fabricated based on resin. Carbon fibers magnetite powders quickly nondestructively through degrading

Sustainable approach for catalytic green epoxidation of oleic acid with applied ion exchange resin

Scientific Reports, Год журнала: 2023, Номер 13(1)

Опубликована: Сен. 19, 2023

Abstract Epoxides were primarily derived from petroleum-based sources. However, there has been limited research on optimizing the process parameters for epoxidized palm oil-derived oleic acid, resulting in its underutilization. Therefore, this study aimed to optimize catalytic epoxidation of acid concerning oxirane content by applying ion exchange resin as a catalyst. Epoxidized was produced using in-situ-formed performic combining formic oxygen carrier with hydrogen peroxide donor. The findings revealed that optimal reaction conditions producing highest an Amberlite IR-120 catalyst loading 0.9 g, molar ratio 1:1., and 1:1.1. By employing these conditions, maximum relative conversion achieved at 85%. rate constants (k) based optimized are determined follows: k 11 = 20 mol L −1 min , 12 2 . validated kinetic model showing good agreement between simulation experimental data.
