“…Historicamente, uma embalagem convencional desempenha proteção (química, física e/ou biológica), comunicação (informação nutricional, marketing e rótulo) e distribuição de mercadorias, desde a produção até o consumo final (Kalpana, Priyadarshini, Leena, Moses, Anandharamakrishnan, 2019). Os materiais de embalagem habituais constituem de vidro, papel, e plásticos derivados do petróleo (Thulasisingh et al, 2021). Geralmente, essas embalagens convencionais possuem uso único, resultando um descarte imediato, o que desencadeia o impacto ambiental adverso (Thuppahige, & Karim, 2022).…”

“…Com este intuito, pesquisas foram iniciadas sobre a degradação térmica e biodegradabilidade no solo, que indicam o quanto embalagens naturais são capazes de suportar, isso deve ser fundamental na avaliação de sua capacidade de tornar-se uma embalagem no mercado (Jaramillo et al, 2016). A biodegradabilidade de uma embalagem pode ser afetada pelas características do polímero estabelecido na confecção da embalagem, origem e condições ambientais como luz, temperatura e umidade, do local de onde é depositada (Thulasisingh et al, 2021).

Apesar das embalagens plásticas serem parte da vida do homem, muito tem-se falado em alternativas para substituir a produção das que são provenientes do petróleo. Como estratégia interessante, o amido, em especial, o de mandioca se destaca como fonte biodegradável, que quando comparado com o material de origem fóssil apresenta alta biodegradabilidade e vantagens mediante ao uso. Muitos estudos já demonstraram algumas vantagens e limitações desta matéria-prima, contudo, mais informações acerca do tema se torna relevante uma vez que, o Brasil é um grande produtor de amido e a produção de embalagens renováveis é de interesse mundial. Assim, o objetivo desta revisão bibliográfica narrativa foi abordar sobre as embalagens biodegradáveis como alternativa promissora para conter o avanço desenfreado da produção de lixo não degradável, demonstrando diferentes aplicações de filmes e revestimentos comestíveis de caráter biodegradável à base de amido de mandioca. Nesse contexto, diversos achados atuais foram inseridos nesta revisão para expor o conceito das embalagens biodegradáveis, além de demonstrar que a biodegradabilidade de uma embalagem pode ser afetada pelas características do polímero utilizado, e nesse sentido o amido demonstrou um tempo de degradação menor do que outros materiais poliméricos e vantagens para seu uso em embalagens. Assim, esta revisão pode servir para uma ampla gama de oportunidade de conhecer o amido de mandioca como biopolímero disponível a ser utilizado em escala industrial, garantindo assim uma maior biodegradabilidade de materiais provenientes desta matriz polimérica e consequentemente uma menor dano ao ambiente.

“…Plastic products are lightweight, durable, and inexpensive, making them suitable for several daily-use products . With the widespread use of plastic products, the generation and disposal of plastic waste have become a critical environmental problem. − Once plastic products are lost or disposed of in nature, photo-oxidation, thermal oxidation induced by sunlight, ,− and biodegradation by microorganisms in the sludge and ocean − accelerate the fragmentation of plastics. Finally, derelict plastics are degraded to particles with sizes ranging from several millimeters to hundreds of nanometers, which are widespread in the environment, particularly in the ocean.…”

Ghost fishing, caused by lost fishing lines and nets, has become a severe problem in marine environments. To eliminate ghost fishing in the ocean, the environmental degradation behavior of fishing lines must be understood. In this study, the environmental degradation of biodegradable nylon 4 fishing lines and commercial nylon 6, poly(ethylene terephthalate) (PET), and poly(vinylidene fluoride) (PVDF) fishing lines was simulated in the laboratory using an artificial weathering tester and biodegradation test in extracted seawater. To understand the degradation mechanism, the chemical and structural changes induced by photo-oxidation and biodegradation were investigated using tensile test, scanning electron microscopy, differential scanning calorimetry, gel permeation chromatography, infrared spectroscopy, and wide- and small-angle X-ray scattering. The results indicated that photo-oxidation occurred in the amorphous phase of the nylon 4, nylon 6, and PET fishing lines during ultraviolet (UV) exposure. The nylon 4 fishing lines exhibited excellent biodegradability, whereas the nylon 6, PET, and PVDF fishing lines could not be degraded by microorganisms in the extracted seawater. Both processes, i.e., photo-oxidation and biodegradation, were confined to the amorphous regions of nylon 4. Note that the PVDF fishing lines could not be degraded by UV exposure and biodegradation and, hence, should be recycled after use.

“…Biopolymers such as proteins, polysaccharides and lipids, with the aid of some additives, appear to be promising raw materials [ 11 , 12 ]. Biopolymers can be obtained from a variety of animal or plant sources; some can be chemically synthesized from bio-based monomers (e.g., polylactic acid) or synthesized by microorganisms (e.g., cellulose, polyhydroxyalkanoates, xanthan) [ 13 ]. An overview of the main biopolymer classes based on their origin and chemical nature is shown in Figure 1 .…”

Biopolymers of different natures (carbohydrates, proteins, etc.) recovered from by-products of industrial processes are increasingly being studied to obtain biomaterials as alternatives to conventional plastics, thus contributing to the implementation of a circular economy. The food industry generates huge amounts of by-products and waste, including unsold food products that reach the end of their shelf life and are no longer usable in the food chain. Milk proteins can be easily separated from dairy waste and adapted into effective bio-based polymeric materials. Firstly, this review describes the relevant properties of milk proteins and the approaches to modifying them for subsequent use. Then, we provide an overview of recent studies on the development of films and coatings based on milk proteins and, where available, their applications in food packaging. Comparisons among published studies were made based on the formulation as well as production conditions and technologies. The role of different additives and modifiers tested for the performances of films and coatings, such as water vapor permeability, tensile strength, and elongation at break, were reviewed. This review also outlines the limitations of milk-protein-based materials, such as moisture sensitivity and brittleness. Overall, milk proteins hold great potential as a sustainable alternative to petroleum-based polymers. However, their use in food packaging materials at an industrial level remains problematic.
