Depending on your trash service you can leave larger items just sitting by the cans and they'll throw it in the truck.
That's pretty standard in my area if you're on a route with the guys riding on the truck and not the robotic arm. Also even on the routes with the arm they'll have "large trash pickup" a couple times per year and a seperate "brush truck" after large storms or hurricanes.
Anyway when you set items by the curb if someone wants them before trash pickup they'll take them. If it's metal at the very least a scrapper will take it.
