Green Biocomposites for Packaging Applications

In recent years, research on environmentally sustainable packaging has been gaining momentum, primarily driven by consumer ecological consciousness. Green biocomposites play an important role in novel and innovative materials for the emerging sustainable packaging industry, being intrinsically biobased and biodegradable. Therefore, the following chapter is aimed to make an overview of the main trends on green biocomposites study and development, their environmental impact and their importance in future production systems. A revision of the polymeric matrices and fillers most widely used for green biocomposites and bionanocomposites manufacture is done, and the results of the latest investigations on the subject are discussed. Besides, their role in active and intelligent packaging is reviewed as well as their implementation for 3D printing technologies. Finally, the relevance of these materials study and development in terms of environmental impact is herein considered, remarking the importance of adequate life cycle assessment of the developed green biocomposites in comparison to conventional materials used for similar packaging applications.Fil: Versino, Florencia.

Recent Advances in Sugarcane Industry Solid By-Products Valorization

Sugarcane is among the leading agricultural crop cultivated in tropical regions of the world. Industrial processing of sugarcane generates sugar; as well as various solid wastes (i.e. sugarcane bagasse, pressmud). Improvement of biotechnology in industrial level, offers opportunities for economic utilization of these solid residues. In the last few decades, sugarcane bagasse and pressmud have been explored in the theme of lignocellulosic bioconversion. The recalcitrance of biomass is a major drawback towards successful exploitation of lignocellulosic residues. Pretreatment by suitable/efficient processes can overcome this limitation. In this regards; physical, chemical and biological treatment systems are brought into our perspective. Chemical and physicochemical methods are capital-intensive but not environment-friendly, in contrast, method like biological treatment is eco-friendly but extremely slow. There are still major technological and economic challenges need to be addressed; e.g. bioprospecting, established more reliable genetically modified microorganisms, upgrade gene cloning and sequencing processes, yield improvement at large scale etc. Productions of value-added products from these solid wastes are discussed in such a way that pinpoints the most recent trends and the future directions. Biofuels, enzymes, organic acids and bio-sorbents production draw a clear sketch of the current and future bio-based products. Nano-biotechnology and genetic engineering could be future trends to improved processes and products. This review serves as a valuable reference material for a wide range of scientists and technologists in the relevant fields
