Seeking to meet as much as possible the requirements of green chemistry, research has been developed targeting processes that enable the use of reagents that are mostly obtained from renewable sources and that allow the absence of catalysts and solvents. In this context, lignocellulosic fibers, as sisal, and their main components, cellulose and lignin, together with oilseeds, such as castor and soybean oil (epoxidized), Figure 1, have been used as raw materials in syntheses in which simultaneously films or composites fiber-reinforced are formed. Hydrogels formed from the deconstruction of lignocellulosic fibers have also been investigated. Regarding the films, they have been formed from the synthesis of biobased polyurethanes, with or without additives, targeting properties, including biocompatibility and antimicrobial, that can potentially lead to a wide range of applications. Syntheses of bio-based polyurethanes or epoxy resins, with the respective reagents previously mixed with the reinforcing agents (short lignocellulosic fibers or mats), have been carried out in molds under temperature and compression aiming at the formation of composites with good properties, with emphasis on impact and flexural strength. These studies are ongoing, but many promising results have already been obtained.
