What is single stream recycling?

• It's when you place all recyclable items into one container

• It's when you sort recyclable materials into separate categories

• It's when you dump all of your recyclables into a stream

• It's when you don't recycle items

Answer explanation

Single-stream recycling began in the 1990s with two main goals in mind. The first was to make recycling easier and more convenient for the consumer with the intention of diverting more waste from landfills. The idea was if items didn’t need to be sorted, residents would be more likely to throw recyclables into the recycling bin rather than the waste bin.

The second goal was to reduce collection costs. By throwing everything into one recycling receptacle, collection trucks can work more quickly and expediently.
