I have roughly 110 (8 by 16) cement pavers that I need to dispose of in Delaware County, PA. How can they be disposed of?
A: Craigslist, curb alert, free pavers.
B: By the side of the road, with a sign "free pavers".
To really make them move, C: by the side of the road, a sign, "pavers, $2 each" (don't expect the $2, but you could get lucky, and the folks that think they are stealing them might be more eager than the ones that are taking them for free.)
Contact your local community garden or Habitat for Humanity and donate them.
Sell them on Craig's list or Ebay!! Those things are valuable. Do you have any neighbors with drainage issues, land slides in their back yards? Find a RESTORE type outfit nearby. They'll come and do all the work (as they should)and take them away. Put an ad up in your neighborhood hardware/lumber yard. Don't forget to go TALK to the manager(s) of the store, they'll know someone who would love to get paver CMU's cheaply.
I am sure that there is a concrete/asphalt recycling place nearby. You just have to load, haul, unload all of this GOLD with no help.
Another option is to use them as a garden wall, similar to ledger stone. 15 to 18 inches high, slightly battered, drainage and soil behind, a thick concrete cap and you've increased the value of your home more than a remodeled kitchen or an extra bathroom. This enables a new dimension to your yard versus 2 dimensional flat.
Look up debris hauling, recycling, concrete removal...if you want to get rid of those pavers you shouldn't have to lift a finger other than making a few calls.
Do you have a local "freecycle" e-mail group? Always works for me, where I live. Just join (free), post your offer, sit back and wait for e-mails from people who want them.
