Single Stream Recycling

My area is starting single stream recycling, but (a) how does this get separated out at the recycling center? (Is it sorted out manually?) And, (b) what if you make a mistake placing a questionably recycleable item in the stream?

FYI: I searched the SDMB archives back 2 years and found nothing matching this question.

I only know what we were told when it started here. Which is yes, it’s separated by hand and non-recyclable items will be removed and discarded.

It’s usually a combination of both hand- and machine-sorting of materials:

Most of the sorting is done by machines using gravity, water, optical sensors, magnets, etc…

Jinx… me too. Today was the first day.

Harford County?? :wink:

I’m going to need a bigger tote. Too many 12oz glass bottles :frowning:
