One thing I've noticed since relocating to Tucson is how many different trash companies there are. I'm actually not sure how many there are. Some just process commercial dumpsters, whilst others focus more on residential. The company that picks up my trash does not pick up my father's garbage even though he only lives two miles away. Those of us outside the City of Tucson get different trash service than the one provided by the city. It just doesn't seem very efficient.
And some companies pick up the recycling the same day as the trash--mine does this. Others pick up recycling on different days. I've never lived anyplace like it. We certainly did not have such options in Colorado.
