逻辑题意不是太明白...

一道旧题了，问题在于句子的最后一句话（加粗)
"This year city services will separate for recycling enough refuse to reduce the number of truckloads of refuse to be incinerated to half of last year’s number"中的"separate"这个词怎么理解，是理解为“city services（主） will separate（谓） for the purpose of recycling xxx...（状语从句）”么？

Last year all refuse collected by Shelbyville city services was incinerated. This incineration generated a large quantity of residual ash. In order to reduce the amount of residual ash Shelbyville generates this year to half of last year’s total, the city has revamped its collection program. This year city services will separate for recycling enough refuse to reduce the number of truckloads of refuse to be incinerated to half of last year’s number.

Which of the following is required for the revamped collection program to achieve its aim?
A.  This year, no materials that city services could separate for recycling will be incinerated.
B.  Separating recyclable materials from materials to be incinerated will cost Shelbyville less than half what it cost last year to dispose of the residual ash.C.  Refuse collected by city services will contain a larger proportion of recyclable materials this year than it did last year.
D.  The refuse incinerated this year will generate no more residual ash per truckload incinerated than did the refuse incinerated last year.
E.  The total quantity of refuse collected by Shelbyville city services this year will be no greater than that collected last year.

个人觉得芦竹理解得没错，是做目的状语，separate这里是“分离处理”的意思。
