### Sustainable Development Goals (SDGs)  
The valorization of mango waste in beer production directly contributes to several key Sustainable Development Goals (SDGs), particularly SDG 12 (\"Responsible Consumption and Production\"), SDG 9 (\"Industry, Innovation, and Infrastructure\"), and SDG 8 (\"Decent Work and Economic Growth\"). This innovative approach offers significant environmental, economic, and social benefits while promoting a circular economy model that integrates waste into production. 1. SDG 12: Responsible Consumption and Production: Reusing mango waste in beer production supports SDG 12 by promoting more responsible consumption and production patterns. This practice aligns with the principles of a circular economy, where agricultural by-products are transformed into valuable products, reducing waste and minimizing environmental impact. The integration of mango waste directly addresses the issue of food waste, which remains a significant global challenge. By utilizing what would otherwise be discarded, this approach reduces the overall carbon footprint of beer production, optimizes resource use, and helps mitigate the environmental impacts of traditional manufacturing methods, particularly water and energy consumption. Furthermore, it encourages industries to rethink waste as a resource, which is essential for driving the transition toward sustainable production models. 2. SDG 8: Decent Work and Economic Growth: The valorization of mango waste can create new economic opportunities, contributing to SDG 8 by fostering job creation and economic growth. This practice stimulates the creation of new markets for agricultural by-products, providing farmers with alternative revenue streams and enhancing the overall profitability of agricultural enterprises. Furthermore, it opens up new opportunities within the brewing industry, particularly in areas such as waste management, product innovation, and the marketing of sustainable beverages. By promoting sustainable practices, this initiative not only strengthens the economic viability of small-scale farmers, but also contributes to the creation of decent work opportunities within the local community, particularly in regions traditionally underrepresented in the brewing industry. 3. SDG 9: Industry, Innovation, and Infrastructure: The incorporation of mango waste into beer production exemplifies industrial innovation, as it challenges conventional brewing processes and encourages the adoption of new technologies and sustainable practices. This innovative approach creates new products and stimulates advancements in biotechnology and waste processing. Moreover, it highlights the need for infrastructure that supports the collection, processing, and transportation of agricultural by-products, an essential component for developing resilient supply chains. By integrating mango waste into brewing, this initiative strengthens local infrastructure, particularly in rural areas, which can have broader economic and social impacts. Such infrastructure development promotes local economies and supports the establishment of circular supply chains that can benefit both the brewing and agricultural sectors. This initiative exemplifies how integrating agricultural waste into industrial production can contribute to broader sustainability goals. As consumers increasingly demand more sustainable products, this practice offers a unique competitive advantage, differentiating products in a crowded market. However, achieving commercial success will require overcoming consumer skepticism regarding unconventional ingredients. Therefore, it will be essential to implement targeted marketing strategies that communicate the environmental and functional benefits of products made from mango waste, ensuring that consumers understand the value and quality of these ingredients. In conclusion, the valorization of mango waste in beer production presents a promising pathway for contributing to multiple SDGs, particularly through its environmental, economic, and social benefits.
