What to do with a broken heavybag.

[Orange Lightning]

How about just standing it up next to a solid wall? This way it won't move. You might have to put some kind of a cushion between the wall and the bag.

You mean just put it up to something where I can pound it regardless? Like strap it to a tree or something? I've thought about it. Continuing too. I don't really have any good options for that. Might end up happening at some point though.
At this current time, I'm just striking soft trees with smooth bark with my palms, the...blade? (part opposite of your thumb for doing chops and hammer fists), and my shoe wearing feet. I heard an inventive idea to wrap a basketball in a towel tied to a rope, and to tie that rope to a post, and then to hit the ball. Interesting. I doubt I'll do that though. I'll see if I can't "upgrade" a tree or post of some sort with a heavybag or padding.
