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.

Circular Chemistry: An Enabler of Circular Economy To Achieve the Zero-Waste Goal

Sustainability & Circularity NOW, Год журнала: 2024, Номер 01(CP)

Опубликована: Ноя. 22, 2024

Abstract The main aims of zero-waste goals are the promotion sustainable production and consumption through societal move toward circular approaches. chemical industry includes a variety processes to produce various useful consumables, but many these have serious negative environmental, health, safety impacts at every level their design, production, processing, uses. Circularity is core eco-design technology in which waste repurposed environmental reduced via 3Rs concepts: reduce, reuse, recycle. integration approaches with chemistry makes it (CC). This article provides brief literature review on CC why important tackle sustainability-related issues. Here we conduct structured opinion as well evidence-based explore role make more sustainable. Fundamental aspects its economy been discussed, concluded that design clean processes, recovery, reuse wastes, reintroducing recovered materials back industrial chain possible scalable. aligns 7 UN’s Sustainable Development Goals, is, 3, 6, 9, 12, 13, 14, 15.

Preparation of poly( endo -norbornene derivatives) with ultra-high molecular weight by combining ROMP and acyclic metathesis reaction

Journal of Macromolecular Science Part A, Год журнала: 2024, Номер 61(11), С. 943 - 952

Endo-norbornene derivatives are much cheaper and more accessible. However, it is difficult to prepare endo-polynorbornenes with ultra-high molecular weight (UHMW) by ring opening metathesis polymerization (ROMP) owing the low activity. The of poly(endo-NB-2OH)n could only reach 309.1 kg mol−1 for 24 h via ROMP. While, UHMW poly(endo-NB-2OH)m was prepared combining ROMP acyclic reaction in shorter time. effects residual monomer, amount H2SO4, concentration, temperature time were investigated depth. P(endo-NB-2OH)m (Mn=2645.5 mol−1, PDI = 1.74) be obtained at 80 °C 5 min H2SO4/G3 as 10/1 concentration 0.1 M. Moreover, P(endo-NBI-OH)m(Mn=1114.2 1.95) also successfully this method. should increase 30/1, reacted 45 steric resistance cyclic dicarboximide. For P(exo-NBI-OH)n lower activity, prolong 3 obtain P(exo-NBI-OH)m(Mn=1716.7 1.93). Finally, P(endo-NB-2alkyne)m, P(endo-NBI-alkyne)m, P(exo-NBI-alkyne)m post-modification. Acyclic a robust universal other functional polynorbornenes, especially endo-polynorbornenes, which not efficiently.
