Microbial PolyHydroxyAlkanoate (PHA) Biopolymers—Intrinsically Natural

Bioengineering, Год журнала: 2023, Номер 10(7), С. 855 - 855

Опубликована: Июль 19, 2023

Global pollution from fossil plastics is one of the top environmental threats our time. At their end-of-life phase, plastics, through recycling, incineration, and disposal result in microplastic formation, elevated atmospheric CO2 levels, terrestrial aquatic environments. Current regional, national, global regulations are centered around banning plastic production use and/or increasing recycling while ignoring efforts to rapidly replace alternatives, including those that occur nature. In particular, this review demonstrates how microbial polyhydroxyalkanoates (PHAs), a class intrinsically natural polymers, can successfully remedy persistent dilemma. PHAs bio-based, biosynthesized, biocompatible, biodegradable, thus, domestically industrially compostable. Therefore, they an ideal replacement for dilemma, providing us with benefits meeting all requirements truly circular economy. PHA biopolyesters green materials stages life cycle. This elaborates production, consumption, profile embedded current topical, 12 Principles Green Chemistry, which constitute basis sustainable product manufacturing. The time right paradigm shift manufacturing, use, disposal. Humankind needs alternatives which, as recalcitrant xenobiotics, contribute deterioration planet. Natural represent shift.

Synthesis, Modification, and Applications of Poly(vinyl chloride) (PVC)

Polymer-Plastics Technology and Materials, Год журнала: 2024, Номер unknown, С. 1 - 40

Опубликована: Ноя. 1, 2024

One of the polymers with biggest production volume is poly(vinyl chloride) (PVC) considering their versatility, durability, lightweight, as well low cost production, plastics have recently become an essential part everyone's daily life. However, increased and usage poses significant environmental problems because incomplete utilization, a lengthy biodegradation period, detrimental effects on living things. This study examines latest findings in PVC research, including its properties, polymerization, modification, recycling, diverse applications. It has been proposed that during along application both inorganic organic thermal stabilizers, can mitigate some basic limiting characteristics PVC. chemistry extended by vast continuous study, mainly chemical transformations this polymeric material. describes modification using different materials active modifying agent. The latter included substitutions, modifications, nucleophilic radicals, removal or dehydrochlorination, grafting polymerizations. PVC's consequences are examined, overview functionalization provided article, discussion main reactivity trends lens recycling.

Circular Economy and Supply Chain Sustainability

Advances in logistics, operations, and management science book series, Год журнала: 2024, Номер unknown, С. 1 - 30

Опубликована: Апрель 9, 2024

Pollution, climate change, and the loss of natural resources are still major concerns that must be addressed immediately. More more, industries realizing they need to include sustainability, social responsibility, circular economy, ethical sourcing in their operations. This chapter aims highlight how principles economy ideas—reducing, reusing, recycling, recovering—may help develop a sustainable supply chain, which is crucial addressing these urgent from industry revolution. Apart environmental considerations, industrial innovation, sustainability inside chains, this also describes those techniques (data analytics, blockchain, internet things [IoT], artificial intelligence [AI], etc.) with economy. Practicing chain management within working towards future more egalitarian, ecologically aware, resilient highlighted chapter.

Microplastics in Seabird Feces from Coastal Areas of Central Chile

Animals, Год журнала: 2023, Номер 13(18), С. 2840 - 2840

Опубликована: Сен. 7, 2023

Pollution from plastic waste thrown into the ocean affects all levels of food chain. Marine species birds are affected by particles different sizes, especially mesoplastics (1 to 10 mm) found in their digestive tract, which mainly cause obstructions. In case microplastics (1.000 µm 1 mm), presence tract these has been widely reported. We studied fecal samples Dominican gull (Larus dominicanus) (n = 14), Magellanic penguins (Spheniscus magellanicus) 8), and Humboldt penguin humboldti) 1) obtained Wildlife Rehabilitation Center Biobío region, Chile. Microfibers various colors were present feces gulls penguins, corresponding composition polypropylene (PP) (83%) rayon (77%). These results demonstrate that microplastic occur coastal environments central Chile suggest they probably circulating

A metabolomics perspective on the effect of environmental micro and nanoplastics on living organisms: A review

The Science of The Total Environment, Год журнала: 2024, Номер 932, С. 172915 - 172915

Опубликована: Май 6, 2024

The increasing trend regarding the use of plastics has arisen an exponential concern on fate their derived products to environment. Among these derivatives, microplastics and nanoplastics (MNPs) have been featured for associated environmental impact due low molecular size high surface area, which prompted ubiquitous transference among all interfaces. Due heterogenous chemical composition MNPs, study particles focused a number studies, as result myriad physicochemical properties that contribute co-transference wide range contaminants, thus becoming major challenge scientific community. In this sense, both primary secondary MNPs are well-known be adscribed industrial urbanized areas, from they massively released environment through multiscale level, involving atmosphere, hydrosphere, lithosphere. Consequently, much research conducted understanding interconnection between those interfaces, motivate spread contaminants biological systems, being mostly represented by biosphere, especially phytosphere and, finally, anthroposphere. These findings highlighted potential hazardous risk human health different mechanisms environment, requiring deeper approach define real exposure. As result, there is gap knowledge high-throughput perspective. review, metabolomics-based overview interfaces was proposed, considering technology highly valuable tool decipher opening novel perspective contaminants.
