Seville launched a scheme to produce electricity from the unwanted oranges that turn into a cleaning menace for the city. The southern Spanish city has begun a pilot scheme to use the methane produced as the fruit ferments to generate clean electricity.
The initial scheme launched by Emasesa, the municipal water company, will use 35 tonnes of fruit to generate clean energy to run one of the city’s water purification plants. The oranges will go into an existing facility that already generates electricity from organic matter. As the oranges ferment, the methane captured will be used to drive the generator.
“We hope that soon we will be able to recycle all the city’s oranges,” said Benigno López, the head of Emasesa’s environmental department. To achieve this, he estimates the city would need to invest about €250,000.
