The depletion of fossil fuels and environmental concerns have driven the development sustainable materials, including bio-based biodegradable plastics, as alternatives to conventional plastics. Although these plastics aid in waste management climate change mitigation, their vulnerability oxidative degradation impacts longevity, durability, performance. Natural antioxidants such tocopherols, flavonoids, tannins, extracted from plants or agri-food waste, present a alternative synthetic stabilizers by enhancing thermal stability polymers like poly(lactic acid) (PLA), poly(butylene succinate) (PBS), succinate-adipate) (PBSA), adipate-co-terephthalate) (PBAT), poly(hydroxyalkanoate) (PHA), starch-based materials. This review highlights recent advances stabilized with natural antioxidants, mechanisms action, role improving material properties for applications packaging. Additionally, it explores impact on recycling processes, advancements composite production techniques, future research directions. Bioplastics can achieve enhanced performance, reduce support circular economy incorporating antioxidants.

Abstract Poly(hydroxyalkanoates) (PHAs) are a class of sustainable, bio-based thermoplastic polymers with attractive physiochemical properties, including non-toxicity, biocompatibility, elastomeric behavior by design, and piezoelectric characteristics. In the ongoing effort to reduce plastics waste, PHAs can play substantial role due their inherent biodegradability free microplastics, customizable versatile applications. This includes tremendous potential in broad range biomedical Biomass-based materials have recently gained great interest health sector, given vast amount interdisciplinary research bioengineering medicine. Implantable biomaterials should not elicit any negative response at implantation site, which differentiates them from general-purpose polymers. do induce thrombosis or antigenic even after being contact blood human body during long-term use. The biocompatibility is also key factor rapid growth proliferation tissues onto within these when served as tissue engineering scaffolds. By application, field was estimated be second-largest market share for PHAs, terms volume, 2022. While PHA-based bring forth opportunities, they present challenges that limited widespread use greater share. A better understanding properties biodegradation rates, production challenges, need cost-effective strategies some hurdles addressed. review paper provides an overview commonly used PHA homopolymers copolymers fields packaging industries. introduction manuscript presents concept bioplastics environmental significance, highlighting urgent alternatives conventional fossil-based plastics. next sections briefly cover synthesis, well homopolymer copolymer formulations, followed application field.

The introduction of bio-based matrices in automotive applications would, principle, increase their sustainability and, case the use secondary raw materials is also involved, even result reduced resource depletion. polymer composite matrix that has been mainly brought forward towards industrial application poly(lactic acid) (PLA), which often proposed as replacement for based on polyolefins fields such packaging and short-term commodities since, general, it matches needs conventional thermoplastic production processes. passage to sector not obvious, though: problems affecting durability, relation with water environment, together requirement outstanding mechanical impact performance appear very stringent. On other hand, PLA obtained durable success additive manufacturing a competitor acrylonitrile butadiene styrene (ABS). Also, perspective 3D 4D printing does be confined bare prototyping.

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.

It has been well known for the past decade that accumulation of food E-preservatives in human body harmful consequences health. Furthermore, scientists have realized despite convenience offered by petrochemical-derived polymers, a circular economy and sustainability are two current necessities; thus, use biodegradable alternative materials is imposed. The packaging sector one most rapidly changing sectors world. In recent years, many studies focused on development active films to replace old non-ecofriendly techniques with novel environmentally friendly methods. this study, self-healable, film was developed using poly(lactic acid) (PLA) as biopolymer, which incorporated nanohybrid solid material natural preservative. This derived via absorption carvacrol (CV) essential oil an activated carbon (AC) nanocarrier.
