Repeating what I posted earlier......

How does the trash hauler cause this much damage without a) knowing it happened and b) reporting it to their supervisor?

Generally speaking......their job is to watch out when handling bulk matter. It's like a crane operator....it's his job to be aware of everything going on in their sphere.

The trash hauler is the one at fault. Go to them - their employer - whatever. You have to present as much documentation as possible. Photos along with written report and as much detail as possible.

That is where I would start before heading in the legalities...
