“…The study conducted by Cerpakovska and Kalnins [66] proved that the PVA/cellulose fiber composites meet the packaging requirements. In addition, the foam plate produced from potato starch, corn fibers, and PVA could be used to replace expanded polystyrene (EPS) due to its biodegradability [67]. The incorporation of essential oils such as clove and oregano oil could extend the shelf life of PVA/cassava wastes (14% fibers) food packaging by reducing their moisture sensitivity [68].…”

Natural fibers are fine examples of renewable resources that play an important role in the composites industry, which produces superior strength comparable to synthetic fibers. Poly(vinyl alcohol) (PVA) composites in particular have attracted enormous interest in view of their satisfactory performance, properties and biodegradability. Their performance in many applications such as consumer, biomedical, and agriculture is well defined and promising. This paper reviews the utilization of natural fibers from macro to nanoscale as reinforcement in PVA composites. An overview on the properties, processing methods, biodegradability, and applications of these composites is presented. The advantages arising from chemical and physical modifications of fibers or composites are discussed in terms of improved properties and performance. In addition, proper arrangement of nanocellulose in composites helps to prevent agglomeration and results in a better dispersion. The limitations and challenges of the composites and future works of these bio-composites are also discussed. This review concludes that PVA composites have potential for use in numerous applications. However, issues on technological feasibility, environmental effectiveness, and economic affordability should be considered.

“…La dificultad para reciclar los plásticos sintéticos derivados del petróleo ha promovido el desarrollo de materiales biodegradables, fabricados de polímeros agroindustriales obtenidos de recursos renovables, abundantes y de bajo costo (Gàspàr et al, 2005;Dogossy y Czigány, 2006;Davis y Song, 2006;Cinelli et al, 2006;Lui y Peng, 2005). Puesto que cerca del 41% de la producción de los plásticos son utilizados para la industria del embalaje, y el 47% de este es utilizado para el embalaje de alimentos (Fomin y Guzeev, 2001), el uso de biopolímeros dentro de este campo es una excelente alternativa para reducir los actuales problemas de contaminación.…”

ResumenEl objetivo de este trabajo fue evaluar el efecto de las fibras naturales obtenidas de residuos agroindustriales en la densidad, el gramaje y las propiedades mecánicas de las espumas termoprensadas elaboradas de almidón de especies nativas, como lo son el camote, la oca y la arracacha. El proceso de termoformado se llevó a cabo a una temperatura de 145 °C y una presión de 60 bar. El tiempo de horneado fue de 10-15 min dependiendo del contenido de agua en la mezcla. Las bandejas fueron caracterizadas por su densidad, gramaje, ensayo de impacto, ensayos de deflexión, colorimetría y sus valores de dureza y fracturabilidad. Las bandejas elaboradas por termopresión a base de almidón de camote-fibra de bagazo de caña de azúcar al 15%, y de almidón de arracacha-fibra peladilla de espárrago al 30% presentaron mayores valores en resistencia a la flexión frente a las elaboradas con otros tipos de almidones y fibras, incluyendo a pruebas en blanco. De manera general, la dureza de las bandejas se ve favorecida con el incremento de fibra, sin embargo, la fracturabilidad decrece o no mejora la integridad de la matriz polimérica. Los resultados mostrados en esta investigación permitirán la elaboración de bandejas biodegradables para distintas aplicaciones industriales.Palabras clave: biodegradable; espumas termoprensadas; almidón de camote, oca y arracacha; fibra de bagazo y peladilla; propiedades mecánicas. AbstractThe aim of this study was to evaluate the effect of natural fibers derived from agro-industrial waste in density, weight and mechanical properties of the termoprensadas foams made of starch native species, such as sweet potatoes, oca and arracacha. The thermoforming process was carried out at a temperature of 145 ° C and a pressure of 60 bar. The baking time was 10-15 min depending on water content in the mixture. The trays were characterized by their density, weight, impact test, deflection tests, colorimetry, hardness, and fracturability values. The trays prepared by thermopressure based on sweet potato starch-bagasse fiber from sugar cane at 15%, and arracacha starch -peladilla asparagus fiber at 30% had higher values in flexural strength versus those made with other types of starches and fibers, including blank tests. Generally, the hardness of the trays is favored with increasing fiber, however fracturability decreases or does not improve the integrity of the polymeric matrix. The results shown in this study allow the preparation of biodegradable trays for various industrial applications.

“…Though some of the synthetics are biodegradable and have excellent mechanical properties, they are currently expensive when compared with their nonbiodegradable counterparts. Due to the low initial costs and the advantage of being biodegradable into useful compost, the bio-based materials such as starch and cellulose can be considered as promising (Shogren et al 1998(Shogren et al , 2002Lawton et al 2004;Cinelli et al 2006).…”

“…The utilisation of starch as a biodegradable, renewable base material for disposable articles such as plates, utensils, and bags is desirable as an environmentally friendly alternative to the current use of nondegradable, nonrenewable petroleum-based plastics (Shogren et al 1998;Cinelli et al 2006).…”

“…However, the use of this material as a substitute for plastics has been severely limited due to its brittleness and hydrophilicity. Subjects made from starch are weak and brittle at low humidity and swell and deform upon exposure to moisture, which is making them unsuitable for most packaging applications (Shogren et al 1998(Shogren et al , 2002Cinelli et al 2006). Duanmu et al (2007) and Satyanarayana (2009) added mineral fillers and wood fibres to improve strength and coated plates with wax and other materials to improve water resistance.…”

Smítková H., Marek M., Dobiáš J. (2013): Starch tray with addition of different components foamed by baking process. Czech J. Food Sci., 31: 230-235.The possibilities of improving starch/water batter foam properties by additions of inorganic and organic compounds, waste sawdust and waste paper pulp were investigated. The most suitable ratio between starch and water was set to 2:3. The best results were obtained when calcium stearate was added to the starch/water tray because it filled the matrix of the tray and improved the surface. The addition of calcium stearate and a low amount of waste paper pulp and/or waste sawdust also brought good results. Higher amounts of waste sawdust and calcium stearate did not produce the compact and smooth surface of starch trays. The addition of polyvinyl alcohol improved these parameters.
