文章大意：这是一篇新闻报道。文章主要介绍西班牙城市塞维利亚的冬季是橙色的季节，但是当地近16500吨的橙子大部分都被作为垃圾掩埋。然而，这一现象即将改变，这些无用的橙子将被用来生产清洁能源。
1 . The over 48,000 orange trees in Seville, Spain, not only fill the city’s air with the pleasant smell of orange blossoms in spring, but they also produce over 16,500 tons of fruit every winter. Though that makes the capital of southern Spain’s Andalusia region Europe’s top orange-producing city, the fruit is too sour to be consumed fresh. While some of the produce is used to make orange jam and an alcoholic drink, most of it ends up in Seville’s landfills (填埋场). However, that may change soon thanks to a clever idea to use the oranges to produce clean energy.
The trial programme is being launched by the city’s council and park department in cooperation with Emasesa, Seville’s water supply and sanitation (卫生) division. Juice from 38. 6 tons of oranges will be left to ferment (发酵) in a specialised facility. The methane (甲烷) released from the fermented liquid will be captured and used to drive a generator to produce clean power. The officials estimate the test run will produce about 1,500 kWh of energy – enough to run one of Emasesa’s water purification plants. To ensure there is no waste, the orange skins, peels, and flesh will be used as fertiliser.
“It’s not just about saving money. The oranges are a problem for the city, and we’re producing added value from waste,” said Benigno Lopez, head of Emasesa’s environmental department.
If successful, by 2023, the city hopes to recycle all the oranges and add the electricity produced back into its power transmission network. In trial runs, one ton of oranges produced 50 kWh of clean energy – enough to cover the daily electricity needs of five homes. The project team estimates that if all the fruit is recycled, it will produce enough energy to power as many as 73,000 residences.
“This project will help us to reach our targets for reducing emissions, energy self-sufficiency, and the circular economy,” Juan Espadas Cejas, mayor of Seville, said in the press conference announcing the trial programme.
