We put our trash out in bags. After we do that, the crows make the rounds and poke holes in the bags as they look for anything to eat. They usually do that when the bag is on the ground and they can sit on the ground to tear holes in the bags and pull stuff out. I have been experimenting to see if putting the bag in a small cart slows them down. So far it seems to be helping, but it would take a closed container to fully stop them. At least it was fun to photograph this one through my window.
