Resumen

This chapter explores the design of value chains for biorefinery processes utilizing vegetable by-products and secondary products from the agri-food industry. In alignment with Agenda 2030s sustainability goals, the chapter emphasizes the untapped potential of plant-based wastes, rich in bioactive compounds that are often lost through traditional disposal methods. It covers both conventional and modern extraction techniques, such as Soxhlet, enzyme-assisted, and supercritical fluid extraction, which are essential for harnessing these valuable compounds. Biological processes, including anaerobic digestion and fermentation, are also examined for their role in producing biofuels like methane and bioethanol. The chapter concludes that optimizing these processes requires advanced tools and pre-treatments to overcome challenges posed by lignocellulosic materials. Life cycle assessment is highlighted as a strategic method to ensure sustainability by balancing environmental, social, and economic factors. Ultimately, the future of vegetable by-product biorefineries lies in integrating innovative technologies, automation, and green solvents, making biorefineries a vital component of the circular bioeconomy.
