Think you know everything about Chicago recycling? Prove it by taking this quiz

Ever since Chicago rolled out citywide curbside recycling in 2011, many residents like to consider themselves recycling experts. However, some items that appear to be recyclable can end up contaminating the carts or clogging up machinery.

If you think you know the answers to these and other recycling questions—or have no clue but are keen to learn—check out this interactive quiz created by Recycle by City in partnership with the City of Chicago. The average score is 74 percent, and just 10 percent of Chicagoan aced all 12 questions. Where do you stack up?
