There are still clean up days in my area, but your volume is considered industrial, not homeowner, can I ask how you ended up with that many in the first place?
Don't know if you have recyclers in your area, but you need to locate those that cut them up for use on top of bunker silo's to hold down the plastic on them, the guys that cut them in my area get paid a fee to cut them in half, but you can donate them to those people, they in turn charge the farmer to do the cutting of them.
Wait long enough and the DNR will mandate you have to get rid of them, in x number of days and have a receipt to prove you disposed of them properly, heaven forbid if someone files a complaint against you to them, then there are fines involved and gets expensive I'm told by several that have gone through it, makes the disposal cost look pretty cheap.
