Nowadays, one of the major scientific challenges is related to the development of chemical-free technologies that do not pose risks to human health and the environment. Thus, substituting petroleum-derived chemicals with renewable resources and using green methods for material synthesis have become central topics for a sustainable future. In this context, nanocellulose extracted from biomass is an excellent starting nano-block. It is abundant in nature, renewable, low in toxicity, and offers numerous practical applications, including existing technologies and the potential for developing innovative ones. During my presentation, I will demonstrate how it is possible to transform Brazil's most abundant agricultural waste, sugarcane bagasse, into renewable materials.
