Seville Oranges: Uses and Benefits

In Seville, the abundance of orange trees creates both a picturesque scene and urban challenges. While the fruit is largely unused locally, it is exported to Britain for marmalade. A new initiative by Seville's water utility company aims to convert the oranges into clean energy, potentially powering thousands of homes. This process not only addresses waste but also contributes to climate change mitigation. The leftover pips and skins are used as organic fertilizer, completing a sustainable cycle.
