products in the other stream. From an end consumer perspective, single-stream is easier to participate in. However, single-stream recycling has disadvantages, including the output of lower quality plastics and paper to recyclers. This lower quality material has to be processed more downstream. The increased flow of decreased quality recyclables from Europe and North America in part due to single-stream recycling was part of China's motivation for launching its

Reduced collection costs because single-compartment trucks are cheaper to purchase and operate, collection can be automated, and collection routes can be serviced more efficiently. Single-stream reduced the amount of time it takes for a driver to collect the recyclables, which reduces the driver time

Phoenix, Arizona, began exploring single-stream recycling in 1989. A contract was awarded to CRCInc in 1992, and its MRF, the first large-scale recycling facility to process commingled materials in North America, began operation in 1993. Subsequently, many large and small municipalities across the

The single-stream option replaces the dual-stream option, which is where people separate certain recyclable materials and place them in separate containers for collection. Typically, dual-stream has partial commingled materials such as glass, plastic and metals in one stream separated from paper

A single-stream system is a complex network of machinery that uses a combination of newer and older technologies to sort materials for recycling, including PET, HDPE, aluminum, tin cans, cardboard and paper.
