托福阅读材料:废物利用

2015-01-22 17:17:45来源:网络

  目前,杉木林积肥场正在考虑一个新的处理食物垃圾的方案。在把香蕉皮和面包屑放进积肥堆之前,公司要用它们来创造替代能源。

  Food waste would be separated and sprinkled with bacteria to help the food begin to break down. Then it would be poured into a closed container called an anaerobic digester, where the decomposing food would start releasing large amounts of methane.

  处理过程是这样的:先把食物垃圾分离出来,添加细菌,帮助食物垃圾分解。然后,注入一个叫作真空消化器的封闭容器,分解的食物垃圾在这里面开始释放大量的沼气。

  Instead of letting that methane escape into the atmosphere, where it could contribute to global warming, Cedar Grove would suck it up and store it. Then they could burn it, to power and heat the compost facility.

  如果这些沼气进入大气层,将会加剧全球变暖现象。杉木林积肥场将把这些沼气收集储存起来。然后,他们可以把沼气当成燃料,给积肥场供电供暖。

  Lawrence Klein, technology and development planner for Cedar Grove, says they could also convert the gas from the food waste to compressed natural gas, to fuel their trucks.

  劳伦斯·克莱恩是杉木林积肥场的技术和发展规划师。他说,他们也可以把食物垃圾产生的沼气转换成压缩天然气,给他们的卡车当燃料。

  "I mean, it's a beautiful image," says Klein. "It's taking a waste product and then driving down the highway with it. I'm excited about it."

  “我是说,这是个美丽的前景。利用废物制成产品,然后用它来驾驶汽车跑在公路上。我为此而激动。”
