The conversion of renewable biomasses into biofuels and chemicals represents a strategic way to reduce the use of fossil feedstock, by contributing in switching to a more sustainable society. The use of agro-industrial wastes does not subtract resources destined for food consumption. In addition, waste utilization would result in a reduction of its accumulation, with a consequent decrease of environmental impact and financial losses due to the relevant disposal. In this context, a wide variety of exploitable agricultural resources can be used to support this sustainable growth. However, the characterization represents the first step towards a targeted and proficient exploitation of the chemical and energetic potential of a residual biomass. In this work, some representative residual (Mexican) biomasses were investigated: pepper residues ( Hungarian yellow and red variety ), coconut shells ( Cocos nucifera ), flamboyant pods ( Delonix regia ), seeds of avocado ( Persea Americana ), palm ( Palma de Coroco ) and nance ( Byrsonima crassifolia ) were chemically characterized and the relevant potential applications for the synthesis of biofuels and fine chemicals were specifically evaluated. Lipids, structural carbohydrates, and lignin were specifically valorized in a proficient cascade of technologies, which aim to exploit the correspondent potential, according to the principles of biorefinery and circular economy.
