Abstract

Currently, the need to develop and commercialize materials based on plant fibres constituents has grown due to the awareness on issues related to environmental impact and sustainable development. Large quantities of lignocellulosic materials are generated worldwide from various human activities. A very important factor is the life-cycle assessment of products based on natural fibres that show an extremely favorable environmental balance. The components with natural fibres consume less power (45%) when compared to components with glass fibres, resulting in lower emissions into the atmosphere. Another very important factor is the diversity of natural fibres in our planet. Pineapple is an important crop in the world, as one of the most appreciated and consumed sources, due to its intense productivity generates a significant amount of co products when processed industrially and even supermarket chains and hortifruts of trade, such as products are sources of compounds (especially cell wall polysaccharides) that can be used for high value-added products such as biofuels, reinforcements in polymeric materials and biodegradable materials for making food packaging.The pell and crown of pineapple will be used for the preparation of biodegradable materials for packaging foods. The hemicelluloses (previously extracted from these fibres) are the molds for the production of films. The cellulose, in turn, be used to prepare nanocrystals which are used as reinforcing material for films hemicellulose. The lignin will also be added at different levels, the nanocomposite films for evaluation of their effects on the films. The extracted pectin is also used for reinforcement in various proportions. This work is focused on the extraction and characterization of pulp, as well as the preparation of nanocellulose, hemicellulose, pectin and lignin from the aforementioned residues (husk and pineapples). They will be prepared nanocomposite films and studied the influence of cellulose nanocellulose and lignin on the mechanical properties, barrier, optical and thermal. (AU)
