【正确答案】 D

【答案解析】[解析] 本题属细节性问题。这个问题出现在文章的最后一段， Shrinking landfill space，and rising costs for burying and burning rubbish are forcing local governments to look more closely at recycling．In many areas，the East Coast especially，recycling is already the least expensive waste management option．对比四个选项，只有D选项other methods are more expensive表达了类似的意思，因此，D选项要比其它三个选项要好，我们选D。
