“…Finally, further improvements could allow even more flexible grades of PHAs or transparent ones through the control of its crystallisation to be obtained (Table 5). This range of interesting properties and processability open up a bright future for PHB in applications ranging from surgical sutures, tissue engineering [87] and agricultural foils to packaging for the storage of food products [88]. Like PVC and PET, it exhibits good barrier properties [89], and can be used in the packaging industry as a biodegradable plastic for contributing to solving environmental pollution problems [90].…”

Abstract. Polyhydroxyalkanoates (PHAs) are gaining increasing attention in the biodegradable polymer market due to their promising properties such as high biodegradability in different environments, not just in composting plants, and processing versatility. Indeed among biopolymers, these biogenic polyesters represent a potential sustainable replacement for fossil fuel-based thermoplastics. Most commercially available PHAs are obtained with pure microbial cultures grown on renewable feedstocks (i.e. glucose) under sterile conditions but recent research studies focus on the use of wastes as growth media. PHA can be extracted from the bacteria cell and then formulated and processed by extrusion for production of rigid and flexible plastic suitable not just for the most assessed medical applications but also considered for applications including packaging, moulded goods, paper coatings, non-woven fabrics, adhesives, films and performance additives. The present paper reviews the different classes of PHAs, their main properties, processing aspects, commercially available ones, as well as limitations and related improvements being researched, with specific focus on potential applications of PHAs in packaging.

“…It is a polymer having hydrophobic and highly crystalline feature 16 , with mechanical properties comparable to a conventional thermoplastic 17,18 . However, application on an industrial scale is limited due to low strain rate, rapid thermal degradation and mainly the high cost compared to conventional thermoplastic polymers 16,19,20 .…”

Polyhydroxybutyrate Composites with Random Mats of Sisal and Coconut Fibers

et al. 2016

Biodegradable polymeric composites using natural fibers have been investigated aiming to mitigate environmental impacts. In this paper, polyhydroxybutyrate (PHB) composites obtained using random mats of sisal and coconut fibers by compression molding in a hydraulic press, and the fiber content varied between 10% and 15% relative to the weight of the polymer. Thermal analyses were performed such as Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA). Flexural and tensile tests were performed before and after conditioning in climate chamber with temperature and moisture. The results of thermal analysis show that the thermal stability of the materials remained, both PHB without fiber as for composites with natural fibers mats. The results of mechanical tests indicated that the PHB without fibers and composites showed similar flexural strength values, while the results of the tensile test PHB without fibers showed resistance to higher tensile composite.

“…O aumento da preocupação mundial com o meio ambiente tem impulsionado a produção de embalagens biodegradáveis como uma opção viável para a gestão destes resíduos [79] . Os polímeros melhor adaptados à biodegradação completa são os naturais, aqueles hidrolisáveis a CO 2 e H 2 O, ou a CH 4 e os polímeros sintéticos que possuem estruturas próximas aos naturais [80,81] .…”

AesumoA mudança de hábito e o aumento do consumismo nas últimas décadas levaram a inovações tecnológicas e consequentemente à maior produção de bens de consumo, o que gerou um aumento na produção de embalagens. As embalagens estão presentes em diversos setores, dentre eles destacam-se as indústrias de alimentos, nas quais as embalagens têm como principal função contribuir para conservação do alimento, além de vender o produto. Diferentes materiais são utilizados na fabricação de embalagens para alimentos, sendo eles os plásticos, metais, vidro e celulose. Cada material possui suas diferentes características para conservar o produto, dentre elas as principais são propriedade de barreira a gases, aroma, luz, água, microrganismos e resistência mecânica. No entanto, apesar das diversas vantagens de sua utilização, seu uso e descarte desordenado gera um grande volume de resíduos sólidos, que estão associados ao impacto ambiental. Em preocupação a essa situação têm-se buscado meios alternativos para reduzir tais impactos podendo destacar a reutilização e reciclagem das embalagens, bem como o desenvolvimento de polímeros verdes e materiais biodegradáveis. Palavras-chaves: meio ambiente, biodegradáveis, reciclagem, resíduos sólidos. AbstractChange of habits and increasing consumerism observed in the recent decades have widely influenced technological innovations, as well as the growth of consumer goods production, which has consequently required a crescent packaging production. Packages are used in diverse sectors, among them the food industry stand out, in which their main functions are to contribute to food conservation and selling the product. Different materials, such as plastics, metals, glass and paper, have been used in the food packaging production. Each material has different attributes that help to conserve the product: gas, aroma, light, water barrier, microorganisms and mechanical strength are the main ones. Despite the several advantages of its application, its uncontrolled use and disposal result in a large volume of solid residues and environmental impact. Concerning this situation, alternative practices, such as reuse and development of biodegradable and green polymers, have been considered in order to reduce the impacts.
