“…Esta capacidad de biodegradación no sólo está asociada a la fuente de origen, sino también a la estructura química de los monómeros y a las condiciones del medio ambiente, lo que a su vez genera cambios en los tiempos de degradación [22,23]. Los biopolímeros biodegradables constituyen una solución al difícil manejo de los desperdicios que generan los polímeros sintéticos no degradables, ya que permiten reducir la carga ambiental [24].…”

RESUMENEl cuidado del medioambiente y el uso responsable de los recursos, ha promovido investigaciones con diferentes biopolímeros que permitan el desarrollo de nuevos materiales que puedan ser empleados en empaques para alimentos. Entre estos biopolímeros se encuentra la fibroína de seda (FS), que representa cerca del 70% de la fibra de seda y puede ser obtenida a partir de capullos de primera calidad o de los desperdicios generados en la producción serícola. En el desarrollo de empaques de alimentos con FS, se pueden dar dos alternativas de producción, una en la que la FS puede ser funcionalizada por otros componentes, y otra en la que se incluye la FS como componente funcional modificando otros biopolímeros. La FS puede conferirle al material de empaque ciertas propiedades, como: aumento de la permeabilidad de oxígeno, resistencia a la rotura y una mayor velocidad de degradación del biopolímero. Este artículo se centra en cuatro temas principales: empaques, biopolímeros en empaques, FS y finalmente, la FS en empaques para alimentos.Palabras clave: Empaques, Materiales poliméricos, Biopolímeros, Fibroína de seda, Biomateriales. ABSTRACTEnvironmental protection and responsible use of resources, have promoted research of different biopolymers allowing to develop biodegradable materials which can be used in food packaging. Among these biopolymers is silk fibroin (SF), this protein represents nearly 70% of the silk fiber and it can be obtained from high quality cocoons or from waste generated in the silk industry. In the development of food packaging with SF, there are two possible alternative of production, one in what the SF can be functionalized by other components and another in which, the FS is included as functional component modifying other biopolymers. In the case of food packaging, the SF can concede desirable properties to the package such as an increase in oxygen permeability, more tensile strength and a higher biopolymer degradation rate. This paper is focused on four main topics: packaging, biopolymers in packaging, SF and finally, the SF in food packaging.

“…Corn zein, wheat gluten, soy protein, and peanut protein have been investigated for potential uses. New building products made in this way are not yet available, but industries such as the paper and colouring industry are beginning to replace synthetic polymers with natural ones [15]. The packaging industry is also making use of natural plastics for food packaging and protective mouldings.…”

Waste minimisation is increasingly being considered as part of a comprehensive approach to sustainable design. Good site practice and procurement systems can realise some reductions in construction and demolition waste, but to significantly reduce waste and create a virtually zero waste building changes in the building design are necessary. To achieve zero waste buildings, inspiration can be drawn and lessons can be learnt from nature. The cyclical characteristic of natural processes, where plants grow, die and biodegrade becoming a resource for new growth, can be applied to building construction. The concept of biodegradable buildings relates to nature at a theoretical level and its implementation in practice can contribute to a comprehensive agenda for sustainable design.This paper reports on a study of the potential for reducing end of life waste associated with buildings by constructing buildings to be biodegradable, and considers the options for integrating biodegradable materials in mainstream construction. The study compares the end of life waste produced by three building designs including a traditional construction, a mainstream advanced design and a maximum biodegradable design. The results identify possible waste reductions of 85% of non-biodegradable waste measured by weight and 93% measured by volume for the advanced design and 99.6% (weight) and 99.9% (volume) for the maximum biodegradable design compared with the traditional construction. Both designs also achieved overall waste reductions of approximately 70% by weight and 20% by volume. The study concludes that feasible and worthwhile waste reductions can be achieved in mainstream housing construction by designing biodegradable buildings.

“…Como resultado dessas mudanças, em nível de organização molecular, ocorre um aumento da extensibilidade e flexibilidade do filme. Os plastificantes largamente utilizados em alimentos são glicerol e sorbitol (Swain et al, 2004;Vieira et al, 2011). O tratamento térmico modifica a estrutura das proteínas, causando exposições dos grupos SH e, consequentemente, produz ligações intra e intermoleculares, promovendo a exposição de grupos hidrofóbicos durante a secagem (Pérez-Gago e Krochta, 2001).…”

RESUMO -Os filmes produzidos a partir de proteínas podem ser utilizados, parcialmente, como embalagens para alimentos, contribuindo para a manutenção da qualidade e minimizando os impactos ambientais proporcionados pelos polímeros sintéticos. Os isolados proteicos de pescado estão sendo estudados para o desenvolvimento de filmes biodegradáveis. O objetivo do presente estudo foi desenvolver e avaliar as propriedades físicas e mecânicas de filmes elaborados à base de isolado proteico de músculo castanha (Umbrina canosai) -IPC. Para tanto, foi elaborado o IPC pelo método de variação de pH. Os filmes foram elaborados pela técnica de casting sob condições alcalinas a partir de 2% de IPC, 30% de glicerol, 90 °C e desidratação durante 16 h a 35 °C. Os filmes apresentaram uma resistência a tração de 8,8 MPa, claros (L* =93,6 e b*= 12,3), opacidade de 11,7%, uma elongação de 5% e espessura de 0,150 mm, sugerindo que uma melhor formulação deve ser elaborada.
