What is the easiest way to get rid of a very large patio door?
You could get one of those large low cost plastic material tarps. Fold it out double thickness on the ground outside. Then lay the glass panels down flat on the tarp to break them up. You can successively break larger pieces down to smaller pieces that you can dispose of in the trash bin. After you have gathered up all the larger pieces for disposal you can use the tarp to bundle all the small shards and slivers of glass for disposal.
