Nowadays, plastic contamination worldwide is a concerning reality that can be addressed with appropriate society education as well looking for innovative polymeric alternatives based on the reuse of waste and recycling circular economy point view, thus taking into consideration future world without quite impossible to conceive. In this regard, in review, we focus sustainable materials, biodegradable bio-based polymers, additives, micro/nanoparticles used obtain new environmentally friendly polymeric-based materials. Although polymers possess poorer overall properties than traditional ones, they have gained huge interest many industrial sectors due their inherent biodegradability natural environments. Therefore, several strategies been proposed improve extend applications. Blending strategies, development composites nanocomposites, shown promising perspectives improving performances, emphasizing biopolymeric blend formulations micro nanoparticles produce fully The Review also summarizes recent developments blends, composites, nanocomposite plasticization, particular naturally derived plasticizers chemical modifications increase compatibility matrices. current state art most important reviewed, mainly focusing synthesis processing methods scalable sector, such melt solution blending approaches like melt-extrusion, injection molding, film forming electrospinning, among others, neglecting degradation processes.

Abstract Background Polyhydroxybutyrate (PHB) has emerged as a promising eco-friendly alternative to traditional petrochemical-based plastics. In the present study, we isolated and characterized new strain of Salinicola salarius, halophilic bacterium, from New Suez Canal in Egypt exclusively potential PHB producer. Further genome analysis strain, ES021, was conducted identify elucidate genes involved production. Results Different PHB-producing marine bacteria were producers. Among 17 bacterial isolates, salarius ES021 showed capability accumulate highest amount PHB. Whole implemented PHB-related strain. Putative identified that can function phaCAB produce this These include fadA , fabG P3W43_16340 (encoding acyl-CoA thioesterase II) for production glucose. Additionally, phaJ fadB key fatty acids. Optimization environmental factors such shaking rate incubation temperature, resulted productivity when growing at 30°C on shaker incubator (110 rpm) 48 h. To maximize economically, different raw materials i.e., salted whey sugarcane molasses examined cost-effective carbon sources. The increased two-fold (13.34 g/L) using (5% sucrose) fermentation media. This medium used upscale 20 L stirred-tank bioreactor yielding biomass 25.12 g/L, 12.88 g/L. Furthermore, produced polymer confirmed Fourier-transform infrared spectroscopy (FTIR), gas chromatography-mass (GC–MS), nuclear magnetic resonance (NMR) analyses. Conclusions Herein demonstrated robust natural producer agro-industrial wastes. detailed characterization presented study identifies genes. However, further metabolic engineering is warranted confirm gene networks required Overall, contributes development sustainable strategies.

Using petroleum-derived plastics has contributed significantly to environmental issues, such as greenhouse gas emissions and the accumulation of plastic waste in ecosystems. Researchers have focused on developing ecofriendly polymers alternatives traditional address these concerns. This review provides a comprehensive overview medium-chain-length polyhydroxyalkanoates (mcl-PHAs), biodegradable biopolymers produced by microorganisms that show promise replacing conventional plastics. The discusses classification, properties, potential substrates less studied mcl-PHAs, highlighting their greater ductility flexibility compared poly(3-hydroxybutyrate), well-known but brittle PHA. authors summarize existing research emphasize applications mcl-PHAs biomedicine, packaging, biocomposites, water treatment, energy. Future should focus improving production techniques, ensuring economic viability, addressing challenges associated with industrial implementation. Investigating biodegradability, stability, mechanical durability, cost-effectiveness mcl-PHA-based products petroleum-based counterparts is crucial. future looks promising, continued expected optimize enhance material expand applications. Interdisciplinary collaborations among microbiologists, engineers, chemists, materials scientists will drive progress this field. In conclusion, serves valuable resource understand sustainable However, further needed methods, evaluate long-term ecological impacts, assess feasibility viability various industries.

Conventional passive packaging plays a crucial role in food manufacturing by protecting foods from various external influences. Most materials are polymer-based plastics derived fossil carbon sources, which favored for their versatility, aesthetic appeal, and cost-effectiveness. However, the extensive use of these poses significant environmental challenges due to fossil-based origins persistence environment. Global plastic consumption is expected nearly triple 2060, exacerbating ecological crisis. Moreover, globalization has increased access diverse range around world, heightening importance providing healthier safer with extended shelf life. In response challenges, there growing shift eco-friendly active that not only protects but also preserves authentic qualities food, surpassing roles conventional packaging. This article provides comprehensive review on viability, benefits, implementing bio-based biodegradable polymers packaging, dual goals sustainability extending
