“…Chitin stands as the predominant amino polysaccharide polymer found in the natural world, serving as the structural foundation that fortifies the exoskeletons of crustaceans and insects, as well as the cell walls of fungi [ 65 ]. Studies have found that chitin not only shares a lot of the chemical and physical similarities with synthetic plastics, but it has also improved oxygen permeability and water vapor properties compared to PE and PS [ 66 ]. Keratin is also chemically and physically similar to synthetic polymers and is often used as a bioplastic alternative for the same reason [ 67 ].…”

Unprecedented plastic production has resulted in over six billion tons of harmful waste. Certain insect taxa emerge as potential agents of plastic biodegradation. Through a comprehensive manual and bibliometric literature analysis, this review analyses and consolidates the growing literature related to insect-mediated plastic breakdown. Over 23 insect species, representing Coleoptera, Lepidoptera, and 4 other orders, have been identified for their capacity to consume plastic polymers. Natural and synthetic polymers exhibit high-level similarities in molecular structure and properties. Thus, in conjunction with comparative genomics studies, we link plastic-degrading enzymatic capabilities observed in certain insects to the exaptation of endogenous enzymes originally evolved for digesting lignin, cellulose, beeswax, keratin and chitin from their native dietary substrates. Further clarification is necessary to distinguish mineralisation from physicochemical fragmentation and to differentiate microbiome-mediated degradation from direct enzymatic reactions by insects. A bibliometric analysis of the exponentially growing body of literature showed that leading research is emerging from China and the USA. Analogies between natural and synthetic polymer’s degradation pathways will inform engineering robust enzymes for practical plastic bioremediation applications. By aggregating, analysing, and interpreting published insights, this review consolidates our mechanistic understanding of insects as a potential natural solution to the escalating plastic waste crisis.

“…After 45 days, during the last stage, the mass decreases significantly until total degradation takes place (day 90). Generally, the biodegradation of chitin and chitosan occurs over 25 days or more [42][43][44].…”

Pachycymbiola brasiliana is a marine snail found in the seas adjacent to the coasts of Brazil, Uruguay, and Argentina, whose eggshells are composed primarily of chitin. In this work, Pachycymbiola brasiliana eggshells were used to prepare films and their structural and physicochemical characteristics were investigated. The main focus was on their mechanical stability, water sorption, and methylene blue rejection. From the FTIR spectra, the bands corresponding to chitin were identified. The differential scanning calorimetric (DSC) data showed that the biopolymer has a glass transition temperature of around 32 °C. The morphological analysis was carried out by using SEM and XRD. The study of the films’ mechanical stability showed an improvement with an increase in water activity. Regarding the methylene blue separation processes, a low permeation through the film and a rejection rate of 94 to 99% were demonstrated. Therefore, Pachycymbiola brasiliana eggshell can be considered a promising source of biopolymers for preparing biodegradable, non-toxic films with valuable separative properties.

“…Chitosan ( Figure 1 ) is a versatile and promising biopolymer that has garnered significant interest in various fields due to its unique characteristics and properties. Derived from chitin, which is predominantly found in the exoskeleton of crustaceans, insects, and the cell walls of fungi, chitosan is the second most abundant natural polysaccharide after cellulose [ 1 , 2 , 3 ]. Its biodegradability, biocompatibility, non-toxicity, antimicrobial properties, antitumor effect and ability to sensitize tumor therapy [ 4 , 5 ] make it an attractive material for numerous applications, particularly in the food industry and medicine [ 6 , 7 , 8 , 9 ].…”

Antibacterial chitosan films, versatile and eco-friendly materials, have garnered significant attention in both the food industry and medicine due to their unique properties, including biodegradability, biocompatibility, and antimicrobial activity. This review delves into the various types of chitosan films and their distinct applications. The categories of films discussed span from pure chitosan films to those enhanced with additives such as metal nanoparticles, metal oxide nanoparticles, graphene, fullerene and its derivatives, and plant extracts. Each type of film is examined in terms of its synthesis methods and unique properties, establishing a clear understanding of its potential utility. In the food industry, these films have shown promise in extending shelf life and maintaining food quality. In the medical field, they have been utilized for wound dressings, drug delivery systems, and as antibacterial coatings for medical devices. The review further suggests that the incorporation of different additives can significantly enhance the antibacterial properties of chitosan films. While the potential of antibacterial chitosan films is vast, the review underscores the need for future research focused on optimizing synthesis methods, understanding structure-property relationships, and rigorous evaluation of safety, biocompatibility, and long-term stability in real-world applications.
