关于West Egg's landfill的argument

nika123UID: 3158898

"Two years ago, consultants predicted that West Egg's landfill, which is used for garbage disposal, would be completely filled within five years. During the past two years, however, the town's residents have been recycling twice as much material as they did in previous years. Next month the amount of recycled material—which includes paper, plastic, and metal—should further increase, since charges for pickup of other household garbage will double. Furthermore, over 90 percent of the respondents to a recent survey said that they would do more recycling in the future. Because of our town's strong commitment to recycling, the available space in our landfill should last for considerably longer than predicted."
这边的since charges for pickup of other household garbage will double怎么理解？是对其它垃圾的分类费用增加，还是说垃圾场收集其它垃圾的费用增加？老题目中是since charges for garbage pickup will double。

抱歉，来讨论下自己的理解。
我个人把它当成一个点来反驳，
since charges for pickup of other household garbage will double.but it does not means the amount of material recycle wil increase, so it cannot make sure whether the space for garbage is enough or not.It may end up that the those cannot recyled one keep on increasing and cause insufficent garbage storage space.

应该是指某些废品的价格涨价了，作者是想借此说明会有更多的人因此回收这些废品。
