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

今年，城市管理部门将专注于回收足够的（非焚化）垃圾，从而减少焚化垃圾的运量至去年的一半。

意思是分出一批垃圾进行回收再利用，从而减少垃圾被焚化的数量，也就减少了Ash的数量了。
