That's funny, because the recycling centers where I live have no problem accepting cardboard.
Well yeah paper's paper, you have to understand big recycling center don't bother with the hastle. There'd be more work & less output. Our pic city pic up doesn't want it nor do the bens all around the shopping centers and school. I'm sure it's because people usually don't break them down before tossing them in.
this is quite the hillbilly thing to try, and probably THE WORST thing i have read on this forum yet. all i have to say is show us pics of this pit of death as soon as its built and by all means ACTUALLY try it.
