‘A role model’: how Seville is turning leftover oranges into electricity
Pilot scheme will use methane from fermenting fruit to create clean power for city water plant
In spring, the air in Seville is sweet with the scent of azahar, orange blossom, but the 5.7m kilos of bitter fruit the city’s 48,000 trees deposit on the streets in winter are a hazard for pedestrians and a headache for the city’s cleaning department.
Now a scheme has been launched to produce an entirely different kind of juice from the unwanted oranges: electricity. The southern Spanish city has begun a pilot scheme to use the methane produced as the fruit ferments to generate clean electricity.
