(Editor's note: The following is from Fairfax County):
Now that the holidays are over be sure to go green and recycle your Christmas Tree as well as any old electronics you may no longer use. Fairfax County residents can recycle televisions, computers and peripheral devices -- including keyboards, speakers, printers, external drives and other such materials -- and unbroken fluorescent light bulbs and tubes on Electric Sundays. There is no charge for Fairfax County residents to participate in Electric Sunday; however, they may be required to show proof of residency.
