Valorization of Agro-industrial Residues by the Recovery of Functional Compounds by Green Technologies: Green Tomato Waste, Pumpkin Residues, and Apple Bagasse as Examples from Mexico
摘要
The circular bioeconomy encompasses two key approaches: the bioeconomy, which focuses on using renewable biological resources to produce sustainable goods, and the circular economy, which aims to minimize waste generation through various methods, such as resource recovery in production cycles. The generation of agro-industrial waste is a global issue with critical implications due to its alarming increase in production rates. This highlights the importance of developing strategies for sustainable valorization. Among these, the recovery of bioactive and techno-functional compounds, particularly for health benefits, stands out as a high-potential approach. Emerging extraction techniques play a fundamental role in improving the efficiency and quality of compound recovery. Notable cases include the extraction of bioactive pectin from green tomato peels (tomatillo), the recovery of carotenoids using green solvents from pumpkin seed industry waste, and the valorization of pectin from apple pomace. These examples highlight innovative strategies and ongoing challenges in leveraging agro-industrial waste as a resource, fostering sustainable practices within the framework of the circular bioeconomy.
