Dual stream recycling collection is gaining appeal in some areas of North America as more and more groups are moving away from single stream recycling at the curb.
Some officials are pointing to dual stream collection as a solution to a recycling market downturn from Chinese import restrictions. While in other cases, a return to dual stream is not directly tied to China, but the market downturn has helped programs explain its benefits.

In the midst of a recycling market downturn, a growing number of small municipal programs across North America are moving away from single-stream at the curb.
Some program officials point to dual-stream collection as a solution to market woes brought on by the disappearance of Chinese companies as downstream buyers. Given the market shift, they say, program changes are necessary to create a clean product that can be marketed to alternative buyers. In other cases, a return to dual-stream is not directly tied to China, but the market downturn has helped programs explain the benefits of the approach.
At this point, program changes are not involving construction of new dual-stream facilities. Communities are making their shifts on the collection side and leveraging existing processing infrastructure.
